Definition Study – Defintion Of EPC Terms Oil & Gas Industy
ACCEPTABLE QUALITY LEVEL
[R]∙ The AQL is the maximum percent defective (or the maximum number of defects per hundred units) that, for purposes of sampling inspection, can be considered satisfactory as a process average
ACCEPTANCE
[R] An act of acknowledging that an activity or item has been reviewed per established requirements without noting any non-approved nonconformances. Acceptance does not imply assumption of responsibilities, endorsing or adding positive authorization.
ACCEPTANCE CRITERIA
[R] A limit is placed on the variation permitted in the characteristics of an item expressed in definitive engineering terms such as dimensional tolerances, chemical composition limits, density and size of defect, temperature ranges, time limits, operating parameters and other similar characteristics.
ACCOUNT CODE (See also CODE OF ACCOUNTS)
[B] The code of accounts enables estimating, charging, reporting and forecasting items of equipment, materials, subcontract and labor cost. The individual account codes should break costs down into many small pieces, but without creating excessive and confusing detail.
For each category of equipment, material and service, the approved bidders list is set up by code of accounts. Thus for each object (deliverable) of work, it is recorded which suppliers are on the list, regardless for which project.
[A] The code of account identifies the object of the work, i.e. the type of deliverable. The code of account is the link between WBS( Work Breakdown Structure), OBS (Organization Breakdown Structure), CBS (Cost Breakdown Structure), PDS (Plant Data Structure), and enables to control a project on costs.
The code of account, being the universal link, can be used in identifying WBS elements (for example to identify an activity), OBS elements (for example to determine who delivers what), CBS elements (for example to identify the level of cost consolidation) and PDS elements (for example to link materials with cost and budget).
[B] Code of accounts is applied for
- tagging and identification of equipment and material
- numbering of technical documents, specs, data sheets, drawings, requisitions and purchase orders
- procurement commodity codes
- scheduling activities in E, P, C
- estimating equipment, materials and services
- recording manhours on timesheets in the field and in the home office
- recording project scope changes
- project accounting and invoices
- project cost and progress reporting
- project document filing

[D] Predefined series of actions, using human, financial or other means.
[S] A certain level in a work breakdown structure.
[P] Task, function or decision that requires work and consumes time.
[A] To an activity is assigned resources. Resources cost money. An activity results into deliverables. Deliverables cost money. The total project budget minus the total money spent (cost) is profit (if greater than zero) or loss (if less than zero)
[A] The owner of an activity is responsible for that activity from beginning till end.
All resources working on a specific activity must book on that activity account, even though the resources may be from different organizational units or disciplines.
[O] An activity should basically be identified by the intersection of WBS, OBS and CBS.
ACTIVITY BREAKDOWN
[B] Structuring of an activity into smaller activities, and possibly again these smaller activities into smaller ones.
ACTIVITY CLASS
[M] Same as ‘task category’. It bundles certain activities with common characteristics (user defined) together in that the activity class or task category specifies the kind of work.
ACTIVITY LEVEL(S)
[A] For example : Project, job, activity class (=task category), activity.

AREA / UNIT (see also WBS)
[O] Logical part of a plant. For Company, an area may have one or more units.
[A] Company Project Controls tends to consider an area to be the same as a unit because usually area versus unit is one-to-one, hence the use ‘AREA/UNIT’.
[B] There are different kinds of areas :
- Scheduling area, based on geography
- Cost area
A scheduling area can be considered as a project that can be engineered, procured and constructed independently from the next area.
A scheduling area cannot be in more than one cost area. Scheduling areas can be summed up into a cost area. Boundaries for a scheduling area are based on geography and never on systems or accounting codes.
[B] In a WBS the first subdivision of for example a hydrocarbon processing complex may consist of process facilities and offsite facilities.
The second subdivision would be the individual process units and the individual offsite units.
The third subdivision would be a geographical subdivision (area) within each of the units. Thus a unit may have one or more areas.
ASSIGNED
[D] Not exactly the same ‘allotted’ or ‘allocated’. It means either to delegate or to have or to use for a specific purpose.
[S] Project management software packages, such as PMW, use assign in the context of resources and tasks/activities.
AS-BUILT DATA
[R] Documented data that describes the condition actually achieved in a product (ANSI N45.2).

[A] Available manhours to be consumed by resources who are working on activities in order to produce deliverables. Budget can also be money available to support deliverables (e.g. services, supplies, etc.), in that for a deliverable to be produced, materials must be purchased which generates cost that must be budgeted.
[P] [for performance = actual performance] MANHOURS FORECAST TO COMPLETE = (ALLOCATED MANHOURS * ACTUAL PERFORMANCE) – ACTUAL MANHOURS.
[P] [for performance = 1:] MANHOURS FORECAST TO COMPLETE = ALLOCATED MANHOURS * ((100 – ACTUAL PHYSICAL PROGRESS) / 100).
[P] [for performance = user defined:] MANHOURS FORECAST TO COMPLETE = (ALLOCATED MANHOURS * USER DEFINED PERFORMANCE) – ACTUAL HOURS.
[P] [for performance = actual performance:] MANHOURS FORECAST AT COMPLETION = ALLOCATED MANHOURS * ACTUAL PERFORMANCE.
[P] [for performance = 1:] MANHOURS FORECAST AT COMPLETION = ALLOCATED MANHOURS * ((100 – ACTUAL PHYSICAL PROGRESS) / 100) + ACTUAL MANHOURS.
[P] [for performance = 1:] MANHOURS FORECAST AT COMPLETION =
ACTUAL MANHOURS + ALLOCATED MANHOURS * (100 – ACTUAL PHYSICAL PROGRESS) / 100.
[P] [for performance = user defined:] MANHOURS FORECAST AT COMPLETION = ALLOCATED MANHOURS * USER DEFINED PERFORMANCE.
[P] REVISED BUDGET = MANHOURS ORIGINAL + MANHOURS CHANGES INTERNAL + MANHOURS CHANGES EXTERNAL.
[A] EXPECTED BUDGET = REVISED BUDGET + MANHOURS CHANGES PENDING.

[B] BUDGET INDEX = (ACTUAL + FORECAST) / ORIGINAL BUDGET;
BUDGET , ORIGINAL -
[S] Initial estimate (baseline) of available manhours.
BUDGET , REVISED -
[O] New estimate of available manhours. Must be approved prior to be used.
[A] REVISED BUDGET = MANHOURS ORIGINAL + CUMULATED MANHOURS CHANGES INTERNAL + CUMULATED MANHOURS CHANGES EXTERNAL.
BUDGETED COST OF WORK PERFORMED (= BCWP) (see also ACWP)
[S] The cost of the completed portion of tasks/activities based on the baseline usage data. Also called EARNED VALUE.
[B] The value of completed work. It reflects the progress made along the contract plan.
BCWP = BUDGET FOR ALL COMPLETED WORK + COMPLETED PORTIONS OF IN-PROGRESS WORK.
[B] BCWP, when compared with ACWP (actual cost of work performed), indicates whether the progress achieved is worth the money spent.
[A] The BCWP is the earned value, i.e. the planned value of the work accomplished.

BUSINESS OBJECTIVE
[A] The objective that an enterprise wants to realize. Business objectives are supported by one or more business functions.
BUSINESS FUNCTION
[A] The definition of a cluster of work performed by an organization to obtain a certain result or situation, which is defined to entirely or partly accomplish a business objective. The work process in an enterprise can decomposed into independent subprocesses; these are called business functions. Business functions are necessary for realizing the business objectives.
[A] A business function is independent of how the work process in an enterprise is delegated to different organizational units. The decomposition into business functions may or may not be reflected in the organizational units of an enterprise.
[A] Business functions are generally considered more stable than organizational units because the organizational units can be changed at any time. Business functions support, however, business objectives. Therefore, business functions will only change if the business objectives change (e.g. because market demands change).
CALENDAR , GLOBAL -
[S] Record of default holidays and business days applicable to all projects. When creating a new project, the PROJECT CALENDAR starts with the same settings as the GLOBAL CALENDAR, but remains independent from it.
CALENDAR , PROJECT -
[S] Record of default holidays and business days applicable to a specific project. Normally takes the values from the global calendar. Changes can be made, however, independently from the global calendar.

[O] Report of deviation from the scope of contract.
[B] Change must be resisted by the project management and only be allowed if it can be proved that the project deliverable will not work without the change and if the change has been fully recorded and authorized by the owner who has accepted the impact upon cost and schedule. A clear distinction between ‘must’ and ‘want’ be made at all times.
Changes have detrimental effect on project performance, such as increasing cost, causing of delay, reducing productivity and worsening of relationships among those involved.
CHANGE ORDER
[O] Deviation, authorized by client and LCV, from the scope of contract.
CHARACTERISTIC
[R] A characteristic is an inherent and measurable property of an item. Such a property may be electrical, mechanical, thermal, hydraulic, electromagnetic, or nuclear and can be expressed as a value for stated or recognized conditions. A characteristic may also be a set of related values of a property, usually shown in graphical form.
CHART OF ACCOUNTS
[W] representing the overall costs of the company at corporate level
Each country/office should establish a link (relation) between the DETAIL CODE OF ACCOUNT and the CHART OF ACCOUNTS. That is the only practical way to make the EPC contractor worldwide adhere to the headquarters CHART OF ACCOUNTS. This concept is already practiced by most offices. Only, a uniform coding structure cq format should be agreed upon.
Classification, such as for example ‘offshore’ versus ‘onshore’, can be expressed in the value of jobnumber, which eliminates the need for an additional coding element.
The company charts of accounts should reflect the type(s) of business we are in.
CHECK
[R] Verification of conformance to a specified requirement by review or inspection. The checks’ intensity, varying from complete to random sampling, depends on the specified requirements. These requirements will be specified in advance.
CHECKING DESIGN
[R] Is the detailed technical examination of a document to make certain that it is accurate and to ensure that all the technical design inputs, design bases and other design criteria have been correctly incorporated (IAEA-50-SG-QA6).
CHEMICAL ANALYSIS (CA)
[R] A product, check or verification analysis of the semi-finished or finished product, usually for the purpose of determining conformance to the specification requirements (ASTM-A751).
CLIENT
[O] A legal entity in the market place, to which Company offers full scope EPC Projects or EPC services.
[R] The organization to which the engineering organization has contracted its services to engineer (design and analyze) designated items or systems contract services may also include procurement and construction of the designated items or systems
CODE
[R] A standard which is recommended or imposed by a regulatory body (ISO 6215, BS 5882).
Note: This definition includes “rules” and regulations”.
CODE OF ACCOUNTS
[W] The codes of account structure is usually as follows :
PROJECT xxxxx (not really needed because jobnumbers are unique)
JOB xxxxx
UNIT xx (always 1:1 with area)
MAJOR CODE OF ACCOUNT x
SUB CODE OF ACCOUNT x
DETAIL CODE OF ACCOUNT xx
TYPE OF EXPENSE xxxxx
This is based on the functional layers :
- Project Management using code of accounts (outer layer)
Cost control (inner layer)
versus
Project Accounting (Inner layer)
General Accounting using company chart of accounts (outer layer)
where Cost Control is subpart of Project Management
and Project Accounting is subpart of General Accounting
and where Cost Control and Project Accounting are interrelated as to ‘interface’ Project Management with General Accounting.
The inner layers connect the outer layers, i.e. are interfaces between the outer layers.
Often there are overlaps between the WBS, CBS and OBS, largely caused by the inclusion of organizational elements in the WBS and the CBS; in other words, the structures are not normalized, i.e. not pure.
The things that need to be done first are :
- Normalize/purify the codes of account in a way that there are no dependencies on organization
- Normalize/purify the work breakdown structure in a way that there are no dependencies on organization
Prerequisites are :
- The WBS must reflect purely the work in order to map activities against. The WBS must not have any organizational elements.
- The CBS must reflect purely the cost of deliverables; the CBS should not have any organizational elements.
- The OBS must reflect purely the organization, i.e. organizational resources only.
Once the structures are normalized, i.e. purified, they can be maintained independently from one another and can be related to one another without any overlap.
The new codes of account structure is therefore as follows :
PROJECT xxxxx (not really needed because jobnumbers are unique)
JOB xxxxx
UNIT xx (always 1:1 with area)
MAJOR CODE OF ACCOUNT x
SUB CODE OF ACCOUNT x
DETAIL CODE OF ACCOUNT xx
Company CHART OF ACCOUNTS (format/structure to be determined)
So instead of TYPE OF EXPENSE there will be company CHART OF ACCOUNTS.
The advantages of this structure are :
- there is automatically a relationship between the CBS and the WBS
- because via the RAM the relationship between the OBS and the WBS is established, there is now automatically a relationship between the OBS and the CBS
- because the CBS is related with the company chart fo accounts, there is now automatically a relationship between the OBS and the company CHART OF ACCOUNTS
- and there is automatically a relationship between the WBS and the company CHART OF ACCOUNTS
Thus it has become possible to produce any composite overview, for example
- who (OBS) does what (WBS) against what deliverables costs (CBS)
- how much did the company spend (CHART OF ACCOUNTS) on engineering (OBS)
- how much did the company spend (CHART OF ACCOUNTS) on materials (CBS) for what type of units (WBS)
In order to ensure supporting multi-office projects and corporate finacial consolidation, each country/office should adhere to the same MAJOR CODE OF ACCOUNT and the same SUB CODE OF ACCOUNT, but be free in the way using the DETAIL CODE OF ACCOUNT.
This means that there should be a uniform coding for MAJOR CODE OF ACCOUNT and for SUB CODE OF ACCOUNT world wide.
Each country/office should be responsible for relating the DETAIL CODE OF ACCOUNT with the company CHART OF ACCOUNTS.
As far as it is not the case, the company CHART OF ACCOUNTS should be adapted to reflect EPC business.
COMMISSIONING
[R] The initial testing and start-up process by which a plant is put into operation (ISO 6215*, BS 5882).
COMMODITY
[A] All physical parts of a plant, that are necessary to accomplish and support the operational configuration of all equipment pieces.
COMPETENT PERSON
[R] A competent person is one who would be recognized as competent by those normally engaged in or responsible for similar activities. If the task is one usually entrusted to persons holding qualifications bestowed by, or recognized by, a professional body, he is expected to possess such qualifications, and where experience is normally required in addition to qualifications, he is expected to have had such experience. Similar principles are applicable where the individual can be expected to be skilled in a particular trade or other activity.
CONFORMITY
[R] The fulfillment of a specified (see also: Nonconformance) requirement by a quality characteristic of an item or service, the assessment of which does not depend essentially on the passage of time (BS 4778).
CONSTRUCTION PHASE
[R] A period which commences with receipt of items at the construction site and ends when the components and systems are ready for turnover to operations personnel (ANSI N45.2).
CONSTRAINED , TIME -
[S] If an activity or task is time-constrained, it must be finished within a specific amount of time.
3
CONSTRAINED , RESOURCE -
[S] If an activity or task is resource-constrained, it must be finished with the resources that are made available to the task or activity.
CONTINGENCY
[B] A provision for an occurrence dependent on chance, accident or uncertain event.
There are always possibilities of errors due to
- engineering omissions or errors
- cost and rate changes
- construction problems
- schedule slippages
- miscellaneous unforeseens
- estimating inaccuracies
Not all things will go wrong, however, an average contingency could be determined for each account. The total contingency (overall) could be available to the project as a whole.
Problem areas in each account code should be thought of. The average contingency percent decreases at each next stage of the project, for example
- stage 0 initial concept prior to finalization of process design
30 %
- stage 1 bulk materials factored but not priced
20 %
- stage 2 completion of basic engineering, p&ids, plot plans, etc.,and preliminary take-offs with quoted prices
13 %
- stage 3 engineering & design complete with final quantities taken-off and purchase orders placed
8 %
- stage 4 mechanical erection complete
4 %
- stage 5 final completion
0 %
CONTRACT
[R] A document which governs the relationship between client and contractor. Within Badger the following types of contracts are used:
Cost Plus Open Ended
Cost Plus Not to Exceed
Cost Plus Guaranteed Maximum
Cost Plus Fixed Fee
Cost Plus Incentive Fee
Firm Fixed Price
Fixed Price with Reimbursable Expenses
Time and Materials
Time and Materials Open Ended
CONTRACT BUDGET BASE (CBB)
[M] Sum of performance measurement baseline and budgeted management reserve. It is the total dollar amount budgeted for the contract.

CONTRACT COST VARIANCE AT COMPLETION
[M] Substraction of the latest revised estimate at completion from the performance measurement baseline.
CONTRACT WORK BREAKDOWN STRUCTURE (CWBS)
[O] The CWBS is critical to effective performance measurement and considerable care needs to be exercised in its preparation.
Integration of the CWBS and OBS at the cost account level may be visualized as a matrix with the functional organizations on one axis and the applicable CWBS elements on the other axis; each organization may then be clearly identified with the work for which it is responsible. Treatment as individual CWBS elements and cost accounts facilitates performance measurement.
CONTRACTOR
[R] Any organization or individual under contract supplying items or services to the client. It may include the terms Supplier, Subcontractor, Fabricator and subtier levels of these where appropriate (ANSI N45.2).
CONTROLLING
[R] The continuous assessment of the most effective use of money, material and resources to maintain a smooth progression towards completion.
CORRECTIVE ACTION
[R] The analysis and implementation of the most effective action to recover or reverseany adverse trend of progress, productivity or cash flow.
[R] Those planned actions taken to ensure that conditions adverse to the achievement of quality requirements are identified and corrected, such as item and equipment malfunctions, deficiencies, deviations, and nonconformances. For significant conditions adverse to quality requirements, the program shall provide that the cause of such conditions be determined and corrective actions taken to prevent repetition (ISO 6215).
COST
[A] Cost can be subdivided into
- cost related to manhours
- cost for materials
- cost for subcontracts
- other cost
Cost predictions are normally channeled to Accounting.
COST ACCOUNT
[B] A project can be broken down into segments to support performance analysis. Such a segment may have one or more work packages. Each cost account is a natural subdivision of the work on a project and should have formally assigned to it the following
- description of the scope of work to be performed
- who is responsible for this work
- the resources required
- a plan, with scheduled starts & finishes
- the work packages that make up (i.e. are below) the cost account
[O] At cost account level, BCWS, BCWP and ACWP are determined.
COST BREAKDOWN STRUCTURE (CBS)
[O] The CBS also includes information about availability and rates of resources.
[O] The cost breakdown structure (cost control structure) is located at the lowest level of the WBS & OBS and its objective is to control the original budget.
The CBS coding structure should be introduced to compare the original budget and the actual costs per work package. The CBS structure depends on the way cost control takes place; for example it can be performed per cost group, cost center or cost element.

COST CENTER
[B] Area of responsibility as it appears in the responsibility matrix.
COST CONTROL
[B] The objective of cost control is to keep the project within budget, which is achieved by early warning on deviations, and the information to take corrective action before costs are out of control.
Cost control refers to costs before, during and after the fact.
The elements of cost control are :
- preliminary estimate must be available at the beginning of design and converted into a preliminary budget
- code of accounts should be prepared so that the cost of each item of equipment, material and labor cost can be estimated, charged and forecasted for the project
- cost trend estimates should include the amount that purchase commitments are over/under budget, and the cost effects of changes in scope, quantities, design criteria and schedule
- definitive estimate should contain the best assessment possible of the effects of inflation; principal uncertainties are construction direct & indirect labor costs and the cost of completing design
- contingency should not be applied as insurance against overrun but rather to cover cost of changes
- management review concerning total definite estimate, contingency and change allowance
- cost forecasting for every account, including those that are under budget
- change orders to be reviewed and approved before implementation; cost effects on each affected code of account should be added to the budget
- schedule monitoring on a monthly basis; activities significant behind schedule will cause increase cost during time.
[B] Cost control is the maintenance of costs within budget by taking corrective actions where necessary, as indicated by the analysis of predicted cost relative to budget.
Cost control is only effective if all personnel involved is cost conscious; for example if a drawing is reviewed, often areas of savings can be found which repeated many times can lead to major savings.
Cost control for Construction seems more evident, because of the physical objects (materials), however, optimization of the design has generally greater impact on the overall project.
COST CONTROL FOR COMMODITIES
[B] Commodity price control can be achieved by :
- Obtain at least 3 competitive quotes; review the market ahead of time to determine which suppliers need work
- Do not issue inquiries until specifications and quantities are firm as to avoid price change after the PO has been placed
- Obtain fixed price quotes or fixed unit prices; do not accept escalation clauses or other price adjustment clauses which cannot be easily monitored
- Do not place orders which are open ended or where the fabricator can invoice to his measurement, in particular for pipe fabrication
COST CONTROL FOR EQUIPMENT
[B] Equipment cost control can be achieved by :
- Do not issue inquiries prematurely; wait until equipment definition is firm so that sellers can bid on definite information
- Obtain competitive bids from at least 3 sellers; search the market ahead of time to determine which vendor shops need work
- Obtain firm price quotations; if escalation clauses are unavoidable, specify an escalation formula which can be monitored and relates to the required delivery
- If attachments may be added or changed, obtain fixed unit prices for these additions prior to placing the PO
- If spares are required, obtain firm price quotations with the bid or before placement of the PO
COST FORECASTING
[B] Final cost can be forecasted for already started individual cost accounts, work breakdown structure items, and organizational cost accounts.
The following elements are used in cost forecasting :
- Performance (index) to date (CPI) = BCWP/ACWP
- Budgeted cost for the remaining work = BAC – BCWP
- Estimate to complete (ETC) = (BAC – BCWP) / CPI
- Forecast cost at completion (EAC) = ACWP + ETC
For the not yet started segments, no forecast can be made, except to take the average overall performance, taking extrapolative forecast as a starting point; for example the CPI for a department involved with a specific cost account can be taken as the initial CPI for that cost account, thus dividing the CPI into the budgeted cost for the remaining work gives the cost forecast for that account.
COST OF WORK PERFORMED (SPI, CPI)
[S] Cumulative actual usage of manhours from the start of the task or activity up to the current project date times billing rate.
[A] MANHOURS COST ESTIMATED AT COMPLETION = {BUDGET} BUDGET FORECAST AT COMPLETION * {RESOURCE} BILLING RATE OF MEMBER ROLE.
[B] COST PERFORMANCE INDEX = BUDGETED COST OF WORK PERFORMED / ACTUAL COST OF WORK PERFORMED;
If CPI (cost performance index) is less than 1, then it can be safely assumed that there is a problem concerning cost.
[M] CPI % = (BCWP / ACWP) * 100; if CPI falls below 100 % then it indicates that less than a dollar’s worth of work was accomplished for every dollar spent.
The CPI is an indicator of spending performance to date and indicates the cost efficiency of a contract or an item as a percentage of the earned value.
[B] SCHEDULED PERFORMANCE INDEX = BUDGETED COST OF WORK PERFORMED / BUDGETED COST OF WORK SCHEDULED;
If SPI (scheduled performance index) is less than 1, then it can be safely assumed that there is a problem concerning budget.
[M] SPI % = (BCWP / BCWS) * 100; if SPI falls below 100 % then it indicates that less work has been accomplished than planned.
[B] If ACWP (actual cost of work performed) is greater than BCWP (budgeted cost of work performed), then CV (cost variance) is less than 0 (zero), thus over cost.
[B] If ACWP (actual cost of work performed) is less than BCWP (budgeted cost of work performed), then CV (cost variance) is greater than 0 (zero), thus under cost.
COST PLUS OPEN ENDED (CPOE)
[R] Cost-plus-open-ended contracts provide for payment of allowable costs plus negotiated burden rates on labour and/or costs, without any funding limitation on expenditures.
COST PLUS NOT TO EXCEED (CPNTE)
[R] Cost-plus-not-to-exceed contracts provide for payment of allowable costs plus negotiated burden rates on labour and/or costs, subject to a limitation on the cumulative expenditures. Contractually, the company is not obliged to incur costs and the customer is not obligated to reimburse the company beyond the estimated funding limit.
COST PLUS GUARANTEED MAXIMUM CPGM)
[R] Cost Plus Guaranteed Maximum price contracts provide for payment of allowable costs plus negotiated burden rates on labour and/or costs up to a ceiling price. The Guaranteed Maximum price differs from a not-to-exceed contract in that completion of the contract is required regardless of cost. Sharing agreements may or may not be part of the contract.
COST PLUS FIXED FEE (CPFF)
[R] Cost-plus-fixed-fee contracts provide for payment of allowable costs plus negotiated burden rates on labour plus a negotiated lump sum fee.
COST PLUS INCENTIVE FEE (CPIF)
[R] Cost-plus-incentive-fee contracts provide for payment of allowable costs plus negotiated burden rates on labour and/or costs plus incentive fee amount based upon specific evaluation criteria.
COST VARIANCE (see also SCHEDULE VARIANCE)
[M] A negative cost variance indicates overspending, i.e. the monetary value of the work accomplished is less than the amount spent.
A positive cost variance indicates cost savings, i.e. less than a dollar was spent to accomplish a dollar’s worth of work.
[A] Cost variance is the difference between the budgeted cost of work performed and the actual cost of work performed. A negative value indicates that costs have exceeded the baseline plan; a positive value indicates cost savings.
[B] A negative cost variance indicates a poor performance.
[B] The cost variance can be graphically shown by S-curves; the cost variance is measured on the Y-axis (cost), the schedule variance on the X-axis (time).
[S] COST VARIANCE = EARNED VALUE – ACTUAL COST;
[B] COST VARIANCE = BUDGETED COST OF WORK PERFORMED – ACTUAL COST OF WORK PERFORMED; i.e. CV = BCWP – ACWP;
COSTS
[B] Costs can be subdivided into :
- Home office costs, such as
. salaries & benefits of personnel (engineering, procurement and supporting services)
. overheads for accommodation, facilities and non-chargeable support staff
. miscellaneous, i.e. reproduction, communications, travel, business expenses, computer time
- Construction costs, such as
. wages & benefits of direct hire construction labor
. salaries & benefits & expenses of construction supervisors
. rental, purchase and maintenance of construction tools & equipment
. provision of temporary construction facilities, buildings, utilities, construction supplies and protection materials
In all major subdivisions, the salaries/wages is the major cost that can be controlled
C/SCSC
[B] Integrated approach to project controls that interrelates the work scope definition, the schedule, the estimate or budget, the physical performance, and the actual expenditure.
Basically it comprises the following steps :
- Define the work, using a WBS
- Define coding and numbering, e.g. WBS levels, organizational units, types of activities, etc.
- Define the organization, using an OBS
- Assign responsibility for execution of the work (WBS)
- Schedule the work
- Prepare estimates/budgets per resource
- Establish performance baselines, i.e. integrate the schedule and the cost elements to create performance baselines for each accountcode in the WBS
- Record actual costs (e.g. by WBS account code, by organizational unit, etc.)
- Measure performance (e.g. manhours, costs, quantities, etc. relative to the estimate or budget)
- Compare planned progress (i.e. budgeted cost of work scheduled [BCWS]), earned value (i.e. physical progress, budgeted cost of work performed [BCWP]), and actual cost (actual cost of work performed [ACWP], obtained from Accounting)
- Monitoring and corrective actions.
[O] Contractors also benefit from management control systems employing the C/SCSC approach for performance measurement. Benefits experienced by contractors are
- improved operational discipline
- integration of budget and schedule plans for performance
- added dimension of earned value
- improved planning
- better communication internally and with the customer
- more detailed and earlier project visibility
- increased cost and schedule awareness at all levels, particularly at the lower management levels
[P] Contractor’s management control should include policies, procedures and methods that are designed to ensure accomplishing the following :
- Organization
. Define all authorized work and related resources to meet the requirements of the contract, using the CWBS framework
. Identify the internal organizational elements and the major subcontractors responsible for accomplishing the authorized work
. provide the CWBS and the OBS to integrate contractor’s planning, scheduling, budgeting, estimating, work authorization and cost accumulation
. Identify managerial positions responsible for controlling overhead (indirect costs)
. Integrate the CWBS with the contractor’s functional OBS in a way that permits cost & schedule performance measurment for contractor WBS & OBS
- Planning & budgeting
. Schedule the work in a way as to describe the sequence of work and to identify the significant task interdependencies required to meet the delivery requirements of the contract
. Identify physical products, milestones, or other indicators that will be used to measure performance
. Establish & maintain a time-phased budget baseline at the cost account level against which performance can be measured; initial budgets established for this purpose will be based on the negotiated target cost; any other amount used for performance measurement purposes must be formally recognized by both the EPC contractor and the client
. Establish budgets for all work with separate identification of cost elements (code of accounts) such as labor, material, etc.
. In case work-packages are applied, establish budgets for this work in terms of dollars, hours or other measurable units
. Provide that the sum of all work-package budgets + planning package budgets within a cost account equals the cost account budget
. Identify relationships of budgets or standards to budgets for work-packages
. Establish overhead budgets for the total costs of each significant organizational component whose expenses will become indirect costs
. Identify management reserves and undistributed budget
. Provide that the contract target cost plus estimated cost of authorized but unpriced work is reconciled with the sum of all internal contract budgets and management reserves
- Accounting
. Record direct costs to be controlled by the general books of account
. Summarize direct costs from cost accounts into the WBS, allocating a single cost account to only one WBS element
. Summarize direct costs from the accounts into the contractor’s functional OBS, allocating a single cost account only to one OBS element
. Record all indirect costs allocated to the contract
. Identify the bases for allocating the cost of apportioned effort
. Identify unit costs, etc, as applicable
. The contractor’s material accounting must provide for
- cost accumulation and assignment of costs to cost accounts in a manner consistent with the budgets
- determination of price variances by comparing planned versus actual commitments
- cost performance measurement at the time most suitable for the category of material involved, but no earlier than the time of actual receipt of material
- determination of cost variances attributable to the over (including excessive usage), short or damage of material
- full accountability for all material purchased for the contract, including the residual inventory
- Analysis
. Identify at cost account level, using data from
- BCWS and BCWP
- BCWP and applied (actual where appropriate) direct costs for the same work
- BAC and EAC
- variances resulting from the above, together with the reasons for significant variances, including technical problems
. Identify budgeted indirect costs, actual indirect costs and variances along with the reasons
. Summarize the above information and associated variances through the OBS and the WBS to the reporting level specified in the contract
. Identify significant differences between planned and actual accomplishments together with the reasons
. Identify managerial actions taken as a result on the above
. Based on performance to date and on estimates of future conditions, develop revised estimates of cost at completion for WBS elements identified in the contract and compare these with the contract budget base and the latest statement of funds requirements reported to the client
- Revisions
. Incorporate contractual changes in a timely manner recording the effects of such changes in budgets and schedules; before negotiations of a change, base such revisions on the amount estimated and budgeted to the functional organizations
. reconcile original budgets for those elements of the WBS identified as priced line items in the contract, and for those elements at the lowest level of the project summary WBS, with current performance measurement budgets in terms of
- changes to the authorized work
- internal replanning in the detail needed by management for effective control

[P] Project overall schedule (POS), level II, for the first 6 weeks up to 3 months of a project, issued in anticipation of a project detail schedule (PDS).
EARLY START
[S] The earliest date a task can be started.
[A] The early start of an activity makes only sense if it is certain that there is full productivity throughout that activity and no budget is wasted due to resource idle time.
EARNED VALUE
[M] For certain tasks the percentage of work completed may not equal the percentage earned; for example, when 30 % of the work is complete, the task earns 50 % credit; when it is 75 % complete, it earns 90; etc.
[B] Earned value indicates the accomplishment in terms of budget hours.
[B] Each quantity measurement unit (e.g. tons, cubic yards, number of drawings, etc.) has its particular unit hourly rate. For example, the labor hours for a large concrete pour could be 8 hours per cubic yard. Another example, the hourly rate for a piping isometric might be 5 hours, whereas the rate for a P&ID could be 350 hours. Thus the
EARNED VALUE IN BUDGET HOURS = QUANTITY * BUDGETED HOURLY RATE;
[B] For effective performance measurement, the work must be subdivided into packages in which the measurement units and the hourly rates are the same for all quantities in the package. The measurement units and the unit hourly rates must be the same as those in the budget.
[B] The earned value is the multiple of the quantity completed times the milestone percent times the unit hourly rate.
[B] The earned value is the number of units or quantity that has reached a milestone, times the milestone percent, times the unit hourly rate.
[B] The cost of the completed portion of a task or activity based on the baseline total usage. The usual elements are :
- budgeted cost of work scheduled, i.e. the cost of baseline total usage up to the project as-of date
- actual cost for work performed, i.e. cost of cumulative actual usage
- estimate at completion, i.e. estimated cost of resource usage at the completion of a task or activity (= actual plus estimate to complete).
[P] For LGV, according to the PROMISYS documentation, the earned value curves should contain
- actual man-hours for work performed
- budgeted manhours for work scheduled
- budgeted manhours for work performed
[B] In fact, earned value is another expression for reliable measurement of progress of work done that is percentage complete.
[A] EARNED VALUE = ALLOCATED MANHOURS * PHYSICAL PROGRESS;
[P] EARNED WEIGHT VALUE = ALLOCATED MANHOURS * PHYSICAL PROGRESS;
[P] ACTUAL PHYSICAL PROGRESS OF PDS = (SUM EARNED WEIGHT VALUES PWS) / BUDGET MANHOURS;
EARNED VALUE ANALYSIS (= EVA)
[S] Also called PERFORMANCE MEASUREMENT, which is a calculation of actual work accomplished in relation to what was planned when the BASELINE BUDGET was established.
EIS (= EXECUTIVE INFORMATION SYSTEM) INFOCENTER
[A] For an EPC contractor an executive information system would allow to keep track of the project progress at all levels in a work breakdown structure. Any change at a certain level immediately shows the affected higher levels. From any level, any lower level can be zoomed into for more details.
Technically, an EIS is supported by (fourth generation) software that can transparently (for the user) access and relate any database and aggregate at any predefined level in the work breakdown structure. EIS is the ultimate infocenter front-end to support decision making.
EIS should provide the possibility to relate the WBS and the OBS to zoom into the responsibility assignment matrix, for which it would be advisable to include the accountnumber in activity identification because any OBS element working on a WBS element should book on that WBS element.
[A] An EIS works only as good as the underlying method of project progress control. A good method is :
- Establish a deliverable oriented WBS (Work Breakdown Structure) and an overall schedule derived by adding logic between the elements at a given level. The calculated dates impose constraints on lower levels of the structure.
- Establish an OBS (Organization Breakdown Structure)
- Establish a RAM (responsibility Assignment Matrix) with cost centers on the grid. The RAM shows on one axis which OBS element is responsible for what cost centers, and on the other axis which WBS element (deliverable) is associated with what cost centers.
The cost center is a control point where
. responsibility is assigned
. budgets are assigned
. costs are approved
. schedules are approved
. baselines are maintained
- Establish procedures for management of cost centers
- Break down each cost center into work packages to form the detail schedule
- Setup dependencies between work packages for critical path analysis of the plan
- Spread the resource requirement over the duration of the work package, calculating the quantity and associated cost of each resource, per accounting period, using the project calendar
- Establish a CBS (Cost Breakdown Structure) and detail the resources in the structure. Link the CBS with rate tables. Include resource availability.
- Manage each cost center by
. developing detail breakdown of tasks, including start & end dates and float
. assigning resourtces to the plan to obtain detailed cost estimates and resource plans
. reschedule the plan to obtain optimum usage of resources
. revise the latest estimate where needed
. produce forecasts from actuals and latest estimates
. enter actual manhours and costs expended against the plan
. summarize to cost center level for performance reporting
- Record actuals (cost and quantities) against cost center
- Summarize (roll-up) costs and quantities through each level of the structure
- Using baseline, progress and actuals, calculate the Earned Value (BCWP) to measure the true amount work performed, and how this varies from what was budgeted and what was actually spent.
- Report via the structures that is most appropriate to the various project responsibles, for example
. in numeric form within the WBS, OBS, CBS and RAM
. predefined graphs concerning a cost center or any element of the structures or of the RAM
. highlight any relevant aspect of the project per individual requirements
The important point is that the method must be refelected in a data structure that is congruent with the breakdown structures (WBS, OBS, CBS, RAM)

ESTIMATE
[O] A statement that tells what it takes to deliver something. Sometimes called ‘guesstimate’.
[B] Most EPC contractors use standard unit hourly rates (i.e. standard hours, basic hours) for their activities. The standard hours reflect the time it would take to perform an activity under normal conditions. For plants built under different conditions, the standard hourly rates are adjusted by a project productivity factor.
BUDGET HOURS = STANDARD HOURS * PROJECT PRODUCTIVITY FACTOR;
The productivity factor may be different for each work package within a project, or may be a constant for a discipline or for a department/section.
[B] OVERALL PROJECT ESTIMATE MATRIX is composed of PROJECT CODE OF ACCOUNTS (for example : equipment [heaters, vessels, rotating], bulk materials [buildings, piping, instrumentation, etc], services [home office, construction, misc, etc], etc.) and PROJECT SUBDIVISIONS (for example : process plants [crude unit, reforming unit, etc], utilities & services [water facilities, fuel facilities, waste disposal, etc], civil works [fences, roads, dikes, etc]). The matrix is used to support estimating.
[B] At various project stages, particular estimating can be done, for example :
- Conceptual stage : Order of magnitude estimate, derived from curves or return costs from previous similar projects.
- Process design complete : Preliminary control estimate
- Basic engineering complete : Definitive estimate
- Quantities and prices known : Detailed or check estimate
[A] Estimates must be done only by the owner of the area of estimation, noone else.

[R] Description of a certain work procedure and determined pattern of action in given situations (NS 5801).
LEAD AUDITOR
[R] An individual qualified to organize and direct an audit, report audit findings, and evaluate corrective action (ANSI N 45.2).
LINE DESIGNATON TABLE
[R] Listing of engineering flow diagram pipelines. It contains additional information including maximum temperature for thermal stress calculations, operating pressure and temperature, design pressure and temperature, testing pressure and medium, insulation code and thickness, paint code and type of heat-tracing.
LOADING PATTERN
[M] The pattern of usage for a resource assigned to a task or activity. The most widely used loading patterns are : Uniform, front, back, contour.
LOSS (I.E. UNNECESSARY COST TO THE PROJECT)
[B] To illustrate the influence of the cost of borrowing, consider the following example :
Suppose for a large project $3 billion would be set aside at the start of the job, and the job will take 5 years, then (taking a uniform spread) half of the money would not be put to productive use. If the borrowing cost were 13 percent and the short-term return is 5 percent, then roughly the net loss to the project owner is approximated to be
0.5 * $3 billion * 0.5 * 5 years * (13%-5%) = 300 million
This is of course a very crude calculation, but it does make clear some potential overall costs.

MANHOURS , EFFECTIVE -
[P] Total manhours minus vacation, holidays, sickleave, absence.
MANPOWER (ESTIMATING)
[B] MANPOWER PERFORMANCE INDEX = EARNED VALUE / ACTUAL VALUE;
ESTIMATE TOTAL MANHOURS = PLANNED MANHOURS / MANPOWER PERFORMANCE INDEX;
[A] The required manpower for the remaining period will be based on the manhour estimates to complete given by the Lead Engineers, or calculated based on performance.
MANUFACTURER
[R] One who constructs any class of components, part, or appurtenance to meet prescribed design requirements (ANSI N45.2).
MANUFACTURING
[R] Collective term for purchasing, production, inspection and storing.
MATERIAL
[A] Equipment or Commodities.
MILESTONE
[M] Establishes one or more identifiable elements that contribute to the overall work package. Accomplishing any milestone earns a certain predefined value. Accomplishing all the milestones in the work package means that the work package has been completed satisfactorily.
[A] A predefined end-result on the time axis. Trends in slippage of completion dates for parts of the project can be shown.
[P] A turning point in the execution of an activity. Once a milestone is reached, a certain percentage of completion is assumed.
[D] In general, showing the distance to particular points.
[S] A significant date or event in a project.
[B] Many activities may go through a series of steps before they are completed. For example, in the field a foundation must first be excavated, then formed, concrete added and finally grouted out. Another example, a drawing is first drafted, then reviewed for design, then material taken off and finally issued for construction. These steps are completion points in time. The earned value is the number of units or quantity that has reached a milestone, times the milestone percent, times the unit hourly rate.
MILESTONE DATES , SCHEDULED -
[P] Result of distribution (according to manhours distribution method) of allotted manhours from start date to finish date (including no-work days).
MONITORING
[B] To determine specific problem account areas in a project. The next step is to determine the reasons for the deviations from the plan and to assess what corrective actions on significant variances are needed to get back on course.
[R] The continuous assessment of the work completed in every discipline and every stage until completion.
ORGANIZATIONAL BREAKDOWN STRUCTURE (= OBS)
[O] The OBS is used to generate planning reports required by the departments involved in the project. This is made possible by specifying which parties are supposed to supply information and which parties are supposed to receive information during the execution of the project.
To identify all organizational elements in a project organization, the organizational structure should be presented as a coding structure. When each party involved has a place in this organization structure, it will also be allocated a place in the coding structure. By using this code, all involved parties can be identified throughout the project.
An example of OBS coding :
- Location
- Division
- Department
- Section
[B] Is similar in concept as the WBS, being a hierarchical family tree defining the organizational elements in successively greater levels of detail. A specific OBS for the project depicts those organizational elements responsible for performing the work. For example :
Level-0 The company
Level-1 Division, such as Engineering, Procurement, Construction
Level-3 Department, such as (within Engineering) Process, Civil, Piping, Electrical
Level-4 Section, such as (within Civil) Structural
The integration of the WBS and the OBS forms the responsibility matrix.
[M] According to the PACS procedures, the OBS is as follows
Level-1 Company
Level-2 Divisions
Level-3 Departments
Level-4 Sections
Level-5 Task Categories
Level-6 Activities
[A] Please note that Level-1 to -4 are organizational and level-5 to -6 are work related, i.e. should be part of WBS, not OBS.
[W] OBS, organization breakdown structure, representing the project’s organizational resources
ORGANIZATIONAL UNIT
[A] Departments or sections. Organizational units (OU for short) execute one or more business functions; business functions are delegated to one or more organizational units.
PENDING VARIANCE
[M] Difference between total usage and new total usage.
PERCENT COMPLETE
[B] The percentage completion for an accountcode is the sum of the earned values for the work packages divided by the total budget for the account.
[B] PERCENTAGE COMPLETION FOR AN ACCOUNT = SUM EARNED VALUES FOR THE WORK PACKAGES / TOTAL BUDGET FOR THE ACCOUNT; earned values may be in terms of manhours, quantities or costs, depending on the units used to establish the budget for the account
[S] User defined completion estimate used in EARNED VALUE analysis and used to display the status of activities (tasks) in the Gantt chart view.
[A] A completed portion of an activity.
[B] PERCENT WORK COMPLETED = (ACTUAL / (ACTUAL + FORECAST)) * 100;
[B] NET PERCENT COMPLETED = PERCENT PERFORMANCE * WEIGHTED PERCENT;
[P] PERCENTAGE COMPLETE FORECASTED = 100 * (PERIOD END DATE – DATE START FORECASTED + 1) / (DATE FINISHED FORECASTED – DATE START FORECASTED + 1);
[P] PERCENTAGE COMPLETE SCHEDULED = 100 * (PERIOD END DATE – DATE START SCHEDULED + 1) / (DATE FINISHED SCHEDULED – DATE START SCHEDULED + 1 );
[P] PERCENTAGE COMPLETE ACTUAL = 100 * (PERIOD END DATE – DATE START ACTUAL + 1) / (DATE FINISHED ACTUAL – DATE START ACTUAL + 1);
[P] WEIGHTED PERCENT COMPLETE = (PERCENT COMPLETE / 100) * WEIGHTED PERCENTAGE;
[P] WEIGHT PERCENTAGE COMPLETE SCHEDULED = 100 / (SUM REVISED WEIGHT /
SUM WEIGHT PERFORMED SCHEDULED);
[P] WEIGHT PERCENTAGE COMPLETE ACTUAL = 100 / (SUM REVISED WEIGHT /
SUM WEIGHT PERFORMED ACTUAL);
[P] WEIGHT PERCENTAGE COMPLETE FORECASTED = 100 / (SUM REVISED WEIGHT /
SUM WEIGHT PERFORMED FORECASTED);
PERCENT SCHEDULE USED
[B] PERCENT SCHEDULE USED = (DURATION USED / TOTAL DURATION) * 100;
PERFORMANCE ANALYSIS
[B] To determine, for the money spent, whether or not the progress is achieved as defined; the analysis also includes to determine how much should have been spent for the progress achieved, and how this actually compares with what is actually spent.
[B] To compare planned progress, earned value and actual cost.
[A] Performance analysis means finding out whether we are going to be on schedule and on budget, looking at the trend of progress and cost.
[B] Performance measurement for all E, P, C, SC activities must be by means of physically measurable yardsticks (quantities, milestones). Performance measurement must NOT be measured in terms of calendar time or manhours/costs expended.
[B] The purpose of performance analysis is to find out concerning :
- the schedule
. where there is a variance
. why there is a variance
. what effect does the variance have on the project
- the budget
. where there is a variance
. why there is a variance
. what caused the variance
. who is responsible for the variance
. what can be done about the variance
- the trend
. what is the progress
. what is the cost
- forecasting
. what will be the final cost
. what will be the completion date
- monitoring
. what is the rate of built-up cost
. what is the rate of progress
. how does cost relate with time.
[B] For effective performance measurement, the work must be subdivided into packages in which the measurement units and the hourly rates are the same for all quantities in the package. The measurement units and the unit hourly rates must be the same as those in the budget.
[B] On timecards, hours are recorded per work package code (account code). There should be no manipulation of timesheets to make budgets look good. Only accurate reports can aid good projections to complete.
[B] Performance measurement for combined accounts can only measured in terms of dollars. Therefore, each cost account must be estimated with the same units of measurement as its actuals, and all must be capable of being translated into dollars.
[B] The following table is an example that illustrates performance analysis
[B] Performance analysis objective is to answer questions like
- Are we on schedule, on the project as a whole and the individual parts of it ? In case of a variance, why did it occur and who is responsible for it ? What effect will it have on other parts of the project and what can we do about it ?
- Is the work being completed to the budget estimate. In case of a variance, where did & why & how did it occur, who is responsible for it and what can we do about it ?
- Are we going to be on schedule & budget, i.e. what is the trend of progress and cost?
[O] To help forecast future contract performance, it would be very useful to use current and past contractor cost & schedule data concerning similar work.

PERFORMANCE & FORECASTING
[P] Performance is the ratio between time progress (actual manhours spent) versus physical progress.
[P] [for performance = actual performance:] MANHOURS FORECAST TO COMPLETE = (ALLOCATED MANHOURS * ACTUAL PERFORMANCE) – ACTUAL MANHOURS;
[P] [for performance = 1 (i.e. as planned):] MANHOURS FORECAST TO COMPLETE = ALLOCATED MANHOURS * ((100 – ACTUAL PHYSICAL PROGRESS) / 100);
[P] [for performance = user defined:] MANHOURS FORECAST TO COMPLETE = (ALLOCATED MANHOURS * USER DEFINED PERFORMANCE) – ACTUAL HOURS;
[P] [for performance = actual performance:] MANHOURS FORECAST AT COMPLETION = ALLOCATED MANHOURS * ACTUAL PERFORMANCE;
[P] [for performance = 1:] MANHOURS FORECAST AT COMPLETION = ALLOCATED MANHOURS * ((100 – ACTUAL PHYSICAL PROGRESS) / 100) + ACTUAL MANHOURS;
[P] [for performance = 1:] MANHOURS FORECAST AT COMPLETION = ACTUAL MANHOURS + (ALLOCATED MANHOURS * (100 – ACTUAL PHYSICAL PROGRESS) / 100;
[P] [for performance = user defined:] MANHOURS FORECAST AT COMPLETION = ALLOCATED MANHOURS * USER DEFINED PERFORMANCE;
[B] PERCENT PERFORMANCE = TOTAL ACTUAL / TOTAL ESTIMATED;
[A] Contract performance should normally be measured against a formal, contract related baseline rather than against a contractor’s internal operating plan, which may represent something other than the contractual commitment.
PERFORMANCE PERCENT COMPLETE
[M] Percent of work performed to date against the total budget.
[M] PERFORMANCE PERCENT COMPLETE = (100 * BUDGETED COST OF WORK PERFORMED) / BUDGET AT COMPLETION.
PERFORMANCE , WEIGHT
[P] WEIGHT PERFORMED SCHEDULED = REVISED WEIGHT / (100 / PERCENTAGE COMPLETE SCHEDULED );
[P] WEIGHT PERFORMED ACTUAL = REVISED WEIGHT / (100 / PERCENTAGE COMPLETE ACTUAL );
[P] WEIGHT PERFORMED FORECASTED = REVISED WEIGHT / (100 / PERCENTAGE COMPLETE FORECASTED );
PHYSICAL PERCENT COMPLETE
[B] Probably the most widely used tool for schedule monitoring. The standard way of doing is to compare the forecasted progress (curve) with the actual progress (curve).
[B] PHYSICAL PERCENT COMPLETE = TIME SPENT / (TIME SPENT + TIME TO BE SPENT);
PHYSICAL PERCENT COMPLETE is not : TIME SPENT / TIME ESTIMATED TO BE SPENT;
PHYSICAL PROGRESS
[P] Physical progress is the percentage completion of an activity at a given moment.
[P] The actual physical progress curve of a task category starts at the earliest found actual start date of the PWS activities related to the task category, and finishes at the latest found actual finish date.
[P] The actual physical progress curve of a department/section starts at the earliest found actual start date of the PWS activities related to the department/section, and finishes at the latest found actual finish date.
[P] [per progress date :] ACTUAL PHYSICAL PROGRESS OF A TASK CATEGORY = SUM OF EARNED WEIGHT VALUES / BUDGET MANHOURS;
[P] [per week :] SCHEDULED PHYSICAL PROGRESS OF A TASK CATEGORY = ((CUMULATED SCHEDULED MANHOURS PER WEEK) / (TOTAL ALLOCATED MANHOURS PER TASK CATEGORY)) * 100 % ;
[P] [per department/section :] SCHEDULED PHYSICAL PROGRESS OF A DEPT/SECT = ((CUMULATED SCHEDULED MANHOURS PER WEEK) / (TOTAL ALLOCATED MANHOURS PER DEPT/SECT)) * 100 % ;
[P] SCHEDULED PHYSICAL PROGRESS PER PERIOD FOR TASK CATEGORY = (CUMULATED SCHEDULED MANHOURS PER PERIOD / TOTAL ALLOCATED MANHOURS PER TASK CATEGORY) * 100 % ;
[P] SCHEDULED PHYSICAL PROGRESS PER ORGANIZATIONAL UNIT = (CUMULATED SCHEDULED MANHOURS PER PERIOD / TOTAL MANHOURS PER ORGANIZATIONAL UNIT) * 100 % ;
[P] [per week :] FORECASTED PHYSICAL PROGRESS OF A TASK CATEGORY = ((CUMULATED FORECASTED MANHOURS PER WEEK) / (TOTAL ALLOCATED MANHOURS PER TASK CATEGORY)) * 100 % ;
[P] [per department/section :] FORECASTED PHYSICAL PROGRESS OF A DEPT/SECT = ((CUMULATED FORECASTED MANHOURS PER WEEK) / (TOTAL ALLOCATED MANHOURS PER DEPT/SECT)) * 100 % ;
[P] FORECASTED PHYSICAL PROGRESS PER PERIOD FOR TASK CATEGORY = (CUMULATED FORECASTED MANHOURS PER PERIOD / TOTAL ALLOCATED MANHOURS PER TASK CATEGORY) * 100 % ;
[P] FORECASTED PHYSICAL PROGRESS PER ORGANIZATIONAL UNIT = (CUMULATED FORECASTED MANHOURS PER PERIOD / TOTAL MANHOURS PER ORGANIZATIONAL UNIT) * 100 % ;

in an efficient & effective way.
The focusing on costs rather than manhours has become more important because cost is the major issue concerning profitability.
Company is moving towards 3 major areas of business
- EPC (Company), requiring integrated systems
- multi partner (Company + other companies), requiring Company ability to consolidate data from foreign (non-Company) systems
- project management consultant (Company as PMC), requiring the image to be able to act as overall project manager having all the tools available.
PROJECT REPORTS

- Narrative report. Usually distributed to the highest levels of client and contractor management
- Construction scheduling area plan. This is a tangible frame of reference of the amount of work contained within each scheduling area.
- Milestone report. High level concise project planning overview for client, contractor and project management.
- Hotline report. Provides detailed explanation of each critical milestone in the milestone report.

- organizations and people involved in working on the lowest level of the WBS must be identified, i.e. responsibility matrix
- cost accounts cq work packages, i.e. intersection of WBS with OBS; each intersection point has identifiable responsibility, scheduled start & finish, budget and methods to monitor progress, cost & changes
- one level of planning must be integrated with the work packages

REQUIISTION
[R] This document contains the full technical description of the material or work, and the quantities required.RESOLUTION
[R] Determining the disposition of a non-conformance as either use-as-is, repair, rework or replace and the associated instructions.
RAM
[W] responsibility matrix, representing the intersection between OBS and WBS, i.e. who does what; each cell in the RAM may represent a responsibility ‘center’ or a workpackage or an activity
RESOURCE
[B] Whole or part of organization required to complete a project or part of it. Sometimes costs are treated as a resource, as to simplify determination of budget and cash flow requirement analyses.
[S] A human, financial or other means, having the capability to execute or support an activity, partially or wholly.
[O] Any object necessary to perform a task.
RESOURCE LEVEL
[B] To be applied in short term forecasting.
RESOURCE LEVEL = (FORECAST / REMAINING DURATION) * DAYS IN THE PERIOD;
RESPONSIBILITY MATRIX (RAM)
[O] The combination of the WBS (project structure, the work that needs to be done, and when it is scheduled), the OBS (who is going to do the work), and the CBS (to summarize costs and analyze the results), that makes up the relationship of scope of work, organization, cost accounts, budgets, estimates and schedules.
[O] The RAM allocates organizational responsibility for each work element and relates it with the cost account (budget).
[B] The responsibility matrix is the intersection of the WBS and the OBS. Each cell which is formed by the intersection is considered as a unique area in which an element of work scope is assigned to a single organization, thus forming a cost center or a (code of) account.
WBS Level-n : Each descending level provides increasing detailed definitions of the individual tasks, until organizational elements (taken from the organizational breakdown structure OBS) can intersect with the WBS elements. The intersection is the responsibility assignment matrix. Each cell in the matrix is in effect a management control point and can have a cost center number (account code) assigned to. At OBS discipline level, budgets are approved, costs are collected and performance is measured.
[B] For each intersection point of the matrix must be assigned
- description of the work performed
- who is responsible for the work
- time phased budget for the work
- resources required
- schedule start & finish
[A] According to the PACS procedures (re: Integration of OBS and WBS), task categories are in the OBS, but in fact task categories represent work, not organization, thus logically should not be part of the OBS, rather part of the WBS. The responsibility matrix cells, according to the current Company way, are formed by intersecting task categories with work packages; this is not consistent with the definitions of WBS and OBS.

RULES
[R] The Rules are to be understood as being all regulations and requirements decided by the Certification Authorities.
S-CURVE (see also MANPOWER and EARNED VALUE)
[B] S-curves show quantitative progress rather than qualitative because the important thing to know is whether the job is handled volumetrically at a rate appropriate for the given time span, rather than knowing for example which pieces of pipe are erected by a specific date.
S-curves can be applied to show for example
- Material take-off quantities
- Cubic yards of earth excavated
- Feet of cable installed
- Number of requisitions
- Dollar value of purchase orders
- etc.
[B] An S-curve is a graph of the cumulative value of manhours, percentage complete or cost against time. The S-shape is because most projects have a slow start, followed by a longer period of relatively constant activity at a high rate, and finally falling off of this rate to give a slow finish.
In manpower analysis the slope of the curve represents the rate of expenditure of manhours (= velocity) and the rate of build-up or run down of the momentum of work (= acceleration or deceleration of the pace of work).
S-curves should not be smoothened to look good. The purpose is to show deviations from the schedule and act upon, not to simulate a statement of security.SAFETY
[R] Those activities related to securing human life and health, protecting the environment and securing material values.
SAFETY RELATED
[R] Pertaining to those structures, systems and components of installations the satisfactory performance of which is important to the prevention of accidents that could cause undue risk to the health and safety of the public, or to mitigation of the consequences of such accidents (BS 5882*).
SAMPLE
[R] A group of items or individuals, taken from a larger collection or population, that provides information needed for assessing a characteristic (or characteristics) of the population, or which serves as a basis for action on the population or the process that produced it (BS 4778)
Note : The term may also be used to describe a portion of material taken for the same purpose from a larger bulk of material or a sample of observations. Many statistical techniques require that the sample shall be drawn at random.
SCHEDULE
[D] A plan that gives a list of activities, events, etc., together with the timing each activity, event, etc. should happen.
SCHEDULE INDEX
[B] SCHEDULE INDEX = PERCENT SCHEDULE USED / PERCENT WORK COMPLETED;
SCHEDULE PERCENT COMPLETE
[S] Percentage of budget at completion represented by budgeted cost of work scheduled.
[S] SCHEDULE PERCENT COMPLETE = 100 * BUDGETED COST OF WORK SCHEDULED / BUDGET AT COMPLETION.
SCHEDULE PERFORMANCE INDEX (SPI)
[M] An approximate indicator of schedule performnace to date, indicating the schedule status of a contract or an item as a percentage of the earned value.
SPI % = (BCWP / BCWS) * 100;
An SPI of 100 % indicates that all work is completed, but it does not indicate whether the work was compleetd on time.
[S] Index of budgeted cost of work performed and the budgeted cost of work scheduled.
[S] SCHEDULE PERFORMANCE INDEX = COST OF WORK PERFORMED DIVIDED BY BUDGETED COST OF WORK SCHEDULED.
SCHEDULE VARIANCE
[M] Indicates how far behind or ahead of schedule the project is for the current period or for all periods to date.
[S] Difference between the earned value and the planned value. A negative schedule variance means the earned value is less than the plan and the project is behind schedule.
[S] SCHEDULE VARIANCE = EARNED VALUE – PLANNED VALUE; i.e. SV = BCWP – BCWS;
[B] If BCWP (budgeted cost of work performed) is greater than BCWS (budgeted cost of work scheduled), then SV (schedule variance) is greater than 0 (zero), thus ahead of schedule.
[B] If BCWP (budgeted cost of work performed) is less than BCWS (budgeted cost of work scheduled), then SV (schedule variance) is less than 0 (zero), thus behind schedule.
[B] A negative schedule variance indicates that the earned value is less than the plan, and the project is behind schedule.
SCHEDULE VARIANCE INDEX
[S] Index of the variance between budgeted cost of work performed and the budgeted cost of work scheduled.
[S] SCHEDULE VARIANCE INDEX = (BUDGETED COST OF WORK PERFORMED – BUDGETED COST OF WORK SCHEDULED) / BUDGETED COST OF WORK SCHEDULED;
[B] If the schedule performance index is greater than 1 (one), then the earned value is ahead of plan, thus good performance.
If the schedule performance index is less than 1 (one), then the earned value is behind plan, thus poor performance.
[B] SCHEDULE VARIANCE = EARNED VALUE – PLANNED VALUE;
[B] SCHEDULE VARIANCE = BUDGETED COST OF WORK PERFORMED – BUDGETED COST OF WORK SCHEDULED;
[B] Also referred to as the ratio of the earned value to the plan. A value in excess of 1 means that the earned value is ahead of plan, thus good performance.
SCHEDULED AUDIT
[R] An audit applied on a scheduled basis after contract award. This audit evaluates, but is not limited to, the effectiveness of the QA program, pertaining methods, manuals, procedures and instructions.
SCHEDULING

SCRAPPING
[R] Decision to reject a product or a service (NS 5801).
SENSIVITY
[B] The quality of being keenly susceptible and responsible of external forces.
One cost account may have greater impact on the overall project cost than another cost account. The analysis of contingency per cost account indicates the potential areas with high sensivity (for example concerning labor cost versus labor productivity). Additional surveillance for these cost accounts should therefore take place.
SERVICE LIABILITY (See:Product liability
SERVICES
[R] The performance by a supplier of activities such as design, fabrication, inspection, non-destructive, examination, repair or installation (IAEA-50-SG-QA1).

90 % SYNDROME
[B] Progress and expenditure reports look favorable until 90 % completion is reached; then the last 10 % shows a considerable overrun in manhours and schedule time. This is mainly caused by :
- unrealistic manhour budgets and unrealistic schedule periods
- no fixed yardsticks to measure progress against
- assuming that meeting a schedule date means no further charge of manhours (for example follow-up, removal of holds, replies to queries, etc. even after AFC)
STORAGE

TIME AND MATERIALS OPEN ENDED (T&MOE)
[R] A time-and-materials contract with no funding limitation on expenditures.
TIME CARD
[A] At some contractors, hours are booked on charge number (project- or jobnumber) and task category. In fact, to accurately record how many hours are related with what object of work (i.e. deliverable or type of material), the hours should be booked on corresponding codes of account as well, otherwise it is impossible to know for example how much money is spent on earthwork, cooling towers, crystallizers, etc.
In this sample, the time card conatins WBS work breakdown structure), OBS (organization breakdown structure) and CBS (cost breakdown structure) information.
TRACEABILITY

TRAINING
[R] A continuous program of learning to gain knowledge and improve one’s ability in any subject, art or profession. Developing skills and attitudes through self-teaching, working on-the-job, workshop seminars, or formal classroom instructions.
TRENDING
[B] In addition to the overall project, project trending methods can be applied to specific work areas or activities as well. The most common use is for schedule and cost trending. Typical applications are for example :
- Engineering
. manhour expenditure v. budget
. productivity/performance v. target
. drawing production rate v. plan
. final MTO v. estimate
- Procurement
. Inquiry/po cycle time v. plan
. Purchase commitment rate v. target
. Actual vendor delivery time v. promise
- Construction
. Labor manhour expenditure v. budget
. Labor productivity/performance v. target
. Equipment/material erection rate v. plan
. Material quantities used v. estimated
Results of trends should normally not be used as forecasts, but persistent trend indications should be taken into account when making forecasts.
TYPICAL
[R] When associated with a dimension, means that the dimension applies to all features that appear to be identical in size and configuration. The tolerance stated for a dimension labelled typical also applies to each identical feature.
UNIT

UTILITIES FLOW DIAGRAM (UFD)
[R] This document shows how utilities are generated and distributed from the source or supply point to the various parts of an installation. The diagram shows common control loops, additional equipment that is deemed necessary to supply the utility as required and the safety measures necessary. The diagrams shall be drawn in accordance with the geographical layout of the plant.
VARIANCE
[S] Deviation between actual and planned performance. Some elements are :
- schedule variance, i.e. difference between budgeted cost of work performed and the budgeted cost of work scheduled
- cost variance, i.e. difference between budgeted cost of work performed and the actual cost of work performed
- variance at completion, i.e. difference between latest revised estimate at completion and the baseline budget at completion; if value is less than zero, then costs are projected to be over budget when the work is completed
[B] Cost variance shows whether the work done costs more or less than estimated.
Schedule variance gives a cost measure of how far behind or ahead of schedule the cost account, WBS item or the project is.
VARIANCE AT COMPLETION (= VAC) ; AT COMPLETION VARIANCE (= ACV)
[S] The difference between the latest ESTIMATE AT COMPLETION (EAC) and the baseline BUDGET AT COMPLETION (BAC). A positive value indicates that the task is proceeding as planned; a negative value indicates a cost overrun.
[A] At contract level, total budget is usually equal to the contract value; therefore, the difference between BAC and EAC forecasts a contract overrun/underrun.

VERIFIED CERTIFIED MILL TEST REPORT
[R] A CMTR whose authenticity is confirmed by positive proof. Photocopies of CMTR’s are not generally acceptable without further laboratory check testing (to the requirements of the appropriate product specification) unless the vendor or supplier verifies the photocopy by company stamping and signing in ink on the photocopy that the copy is either an original or stating the actual location where the original is held.
VERSION

WITNESS POINT
[R] Point of which the QA department shall be notified and work shall not proceed until required inspections and tests have been witnessed.
WORK BREAKDOWN STRUCTURE (= WBS) (see also : EIS)
[O] The WBS is the preferred management tool for identifying and defining the work. The WBS provides a structured framework for planning and controlling the cost, schedule and performance.
Example of a WBS
- Project phase
- Main group
- Function group
- Group activity
- Task
[O] Hierarchical structure that is used to break down a project into identifiable components.
[S] Usually a deliverable oriented hierarchical tree that organizes and defines the project tasks that are necessary to accomplish project objectives.
[B] For each intersection point of the matrix must be assigned
- description of the work performed
- who is responsible for the work
- time phased budget for the work
- resources required
- schedule start & finish
These cost accounts represent sizable amounts of work (-packages); each of them could be broken down into lower level tasks and job assignments.
According to the WBS, roll-up of physical progress and cost progress is applied.
[M] According to the PACS procedures, a WBS has two sections
- higher level
1 . project
2 . job
3 . area (unit)
- lower level
4 . major code of account
5 . subaccount
6 . work package element (which is an aggregate of various forms of documents), mainly used for inquiry and subcontracting; similar to Company task category.
[O] For each WBS element, cumulative values can be monitored, i.e. budget, earned value, actual costs, re-estimate and cost variance.
[B] A large project can be subdivided into its various units, areas and plant elements to facilitate control and reporting. The number of sub-project numbers should be kept to a minimum to give reasonable control. On a major multi-unit project the following breakdown is recommended
- overall project number for summary cost reports and common/bulk requirements
- individual sub-project numbers for each major identifiable process unit within complex
- one or more sub-project numbers for offsite systems, depending on size and scale
- separate sub-project numbers for geographically distinct locations such as marine terminals, rail loading, dispatching stations, etc.
[B] A WBS has various levels :
- Level-1 of a project WBS represents the quantified project objective, i.e. the total facility.
- Level-2 contains the major work segments grouped as subprojects. These work segments may be several process units comprising a process area or aggregation of services.
- Level-3 is subordinate to level-2 and further defines the project in terms of individual plant units as in a process area.
- Level-n : Each descending level provides increasing detailed definitions of the individual tasks, until organizational elements (taken from the organizational breakdown structure OBS) can intersect with the WBS elements. The intersection is the responsibility assignment matrix. Each cell in the matrix is in effect a management control point and can have a cost center number (account code) assigned to. At OBS discipline level, budgets are approved, costs are collected and performance is measured.
[W] WBS, work breakdown structure, representing the project’s deliverables
WORK PACKAGE
[A] A collection of activities, materials, manhours, equipment, etc. that is needed to reach a specific deliverable.
The NAM for example calls work packages ‘cost, time, resource’, which is the same as CTR-code used by Company.
A work-package may have 1 or more codes of accounts.
WORK PROCESS
[A] A specific cluster of work performed by a human resource or machine, in order to obtain a certain result or situation, which is defined to execute one or more business functions.
WORK STANDARD
[R] Document or physical specimen giving example of professional performance of work.
