DEVELOPMENT OF COST ESTIMATE PLANS AS
APPLIED IN ENGINEERING, PROCUREMENT, AND
CONSTRUCTION FOR THE PROCESS INDUSTRIES
TCM Framework: Reference 7.3 Cost Estimating and Budgeting
June 12, 2009
INTRODUCTION

Purpose

This recommended practice (RP) of AACE International (AACE) is a guideline for development of cost
estimate preparation plans for engineering, procurement and construction (EPC) projects in the process
industries.

The purpose of a cost estimate preparation plan (herein referred to as "estimate plan") is to establish and
communicate how the preparation, development, review and approval of the estimate will be completed.


Background

AACE International's Total Cost Management (TCM) Framework[4] section 7.3.2.1 "Plan for Cost
Estimating and Budgeting" highlights the need to develop estimate plans. This RP delineates industry-
specific practices for development of an estimate plan as they are applied to EPC projects in the process
industries. (A future AACE International RP will provide a guideline for development of a generic cost
estimate plan.)

Cost estimating in the hydrocarbon processing industries (e.g.; chemical, refining, petroleum production
facilities, etc.) has evolved to a relatively advanced state over more than four decades of application.
These industries have developed many common practices and identified industry-specific best practices
through benchmarking and knowledge-sharing. The practices reflected in this document are a result of
compiling notes made by industry practitioners, lessons learned and publicly available documents.


Scope

With reference to the TCM Framework, this document addresses the steps before and after the "Plan for
Estimating and Budgeting" step to the extent necessary for an effective estimate plan.

This document is primarily focused on estimates prepared for project sanction purposes of land-based
facilities. Typically, project sanction is based on a Class 3 estimate. Estimate plans for other classes of
estimates may be adapted from this document.

The basic principles are applicable to all contracting strategies and asset owner (herein referred to as
"owner") configurations. For example, contracting strategies may be in the form of reimbursable
engineering with fixed price procurement and construction and/or EPC alliances, etc. Owner
configurations may include self-perform, partnerships with a named "operating company" or consortiums
responsible for managing the project/program and so on. Some key principles are:


Preparation of an estimate plan helps to ensure successful estimate completion in an effective
and timely manner.

Engaging key stakeholders in the estimate planning process prior to the start of the estimate
development process, improves the likelihood of meeting estimate objectives.

The estimate plan defines what information is required from who and when.

An approved estimate plan provides a duly authorized basis to proceed with the estimating effort,
clarifies requirements and responsibilities.

RECOMMENDED PRACTICE

This recommended practice is divided into three main sections:

1. The Estimate Development Plan Process defines the main steps and discusses issues to be
considered in preparing an estimate plan.
2. The Estimate Plan Format and Content provides a suggested format for an estimate plan along
with annotations. It is designed to allow practitioners to use and modify it as needed for their
specific situation.
3. Appendices contain sample formats which are used in conjunction with the estimate plan.


ESTIMATE DEVELOPMENT PLAN PROCESS

Figure 1 illustrates a summary of the estimate development plan process.


Figure 1. Estimate Plan Development Process


Inputs to Estimate Plan Development

It is recommended that owners furnish specifications for estimate plans within the contract or prior to the
contractor(s) preparing an estimate plan. In any case, the onus is with the lead estimator of each
organization to develop an estimate plan which will satisfy the owner's needs. Where multiple contractors
are involved, the owner is ultimately responsible to ensure that all organizations involved are properly
coordinated in terms of scope delineation, estimate delivery timing and consolidation. In cost
reimbursable situations, owner agreement on how the estimate will be prepared before developing the
estimate is crucial. If this is not done, accusations of wasting the owner's money may be directed toward
the contractor and it may result in the owner's refusal to pay for the "wasted effort". It is not only important
in terms of keeping good client relations but also in terms of helping to ensure the owner has properly

understood and clarified what is required. Mature project management organizations have appropriate
estimate review processes in place to provide executives with an understanding of the estimate variability
(risks, uncertainty, etc). Buy-in up front from the owner saves valuable time at the end of the estimating
cycle when the owner project team is under pressure to deliver the estimate to their management.
Ideally, the owner estimator only needs to verify that the contractor performed what was agreed
beforehand and conduct a final benchmarking analysis of the results before recommending approval to
owner project management. Contractor completion of an estimate is only the beginning of the owner's
approval process, therefore it is critical, regardless of contract form, to ensure alignment on timing of
estimate review and delivery requirements at the outset. Owner organizations typically have
predetermined dates when board meetings are held and their agendas are set several months in
advance. Larger projects tend to be separate agenda items. Delays in the estimating process may cause
the project to miss a critical window of opportunity. For smaller projects, the timing and process for owner
annual budgeting decisions need to be understood.

Despite all the effort that goes into cost estimates and the resulting volume of documentation for project
sanction, estimates are usually summarized into a single line input to project economics in the form of a
cash flow. The basis for the time-spread of cash flows must be given careful thought when prepared, and
adequate scrutiny when reviewed. Some organizations designate cash flow development as a function of
scheduling due to the interrelationship between activity timing and costs. In any case, it is advisable to
assign this important task to an experienced person who is knowledgeable in how invoices are paid
relative to work completion and areas where the schedule may not contain activities which reflect
significant cost items. For example, insurance premiums, typical payment terms for large value
equipment (prior to knowing actual terms), or the fact that "variable indirects" tend to be front and back
loaded rather than spread evenly over time. Cash flows developed without adequate analysis and/or
hastily under tight time pressures to support project approval processes may result in economic projects
being cancelled or uneconomic projects being approved. Cash flows are also used for determining
escalation and are therefore a key deliverable to be identified in estimate plans. Owners using the
accrual-based accounting method usually require a cost flow (incurred cost timing) in addition to cash
flow (payment timing). Costs are typically incurred about two months earlier than they are paid but it
varies significantly depending on owner and contractor procedures as well as vendor invoicing habits.
The necessity of an incurred cost flow to accompany the estimate should be clarified prior to completion
of the estimate plan.

Updated scope and project execution plan information are critical to planning estimate development. The
project execution plan describes contracting strategies, work schedules/shifts/overtime, labor sources,
fabrication and modularization, and so on. Checklists are an effective aid to ensure portions of scope are
not omitted. A more advanced approach is to ensure that the estimating deliverables and controlling
documentation are identified for each portion of scope and corresponding execution plans.

The most current schedule information is needed to analyze resource requirements and peaks in addition
to any weather windows, planned outages, tie-in opportunities, etc. This may include potential cost
impacts of plans to perform work less efficiently than normal, or constraints, or innovation.

Estimate data (quantities, hours, costs) should be coded in a manner that considers how the estimate is
prepared (including related source data), reviewed (including benchmarking) and how it will be used for
cost control. Recasting an estimate consumes valuable resources and poorly formatted estimates may
result in situations where the control team takes several months to establish control. The contractor may
need to submit its project code of accounts to the owner for development of cross-reference mapping to
owner's code of accounts. The contractor may be required to provide summarization of project costs
according to owner-specified formats. Any other special requirements must be considered such as: pre-
investment cost breakout; property tax cost breakout; separation of facility ownership values; asset
valuation; asset financial value depreciation and income tax classes; final cost report formats; partner
reporting requirements; currency conversions; etc.

Risks and opportunities from the prior phase and any updates should be addressed (mitigated, accepted,
etc.) such that their disposition is known for the follow-on estimating and risk analysis. Ideally, this is

done in an aggressive manner to improve the chances of producing a good estimate and project
success.

Lessons learned from the prior phase can be a source of opportunities to reduce costs or highlight
significant gaps in past practices which need to be addressed prior to completing the estimate. Any
assumptions that can be removed or clarified should be.

Stating the planned sources of estimating basis such as project historical data is important for obtaining
owner and contractor alignment and confirming validity. This also applies to the estimating tools,
processes, and estimator qualifications.

In summary, all inputs to the estimate and required outputs should be identified and included in the
estimate plan. If requirements are not clear, meetings should be held to outline the estimate planning
process and obtain alignment.


Prepare Draft Estimate Plan

A draft estimate plan is prepared based on all the inputs available including any related clarifications. If
the estimate is to be delivered as part of a larger package which includes other deliverables such as the
scope document, engineering design basis, schedule, execution plan, risk analysis, etc., it should be
reflected accordingly within the estimate plan.

The level of project definition and facility process complexity will have a significant impact on estimate
plan content and volume. For example, a project with a mine or subsurface components, several
processing units, storage facilities, offloading/export facilities, and pipelines will require much more
documentation than a project to install a single process unit or replace a piece of equipment. A multiple
small projects environment where facilities are installed and estimated on a routine basis, may require
less formality and planning than suggested by this guideline if executed by a team of people who have
done so together over several years.

Publishing a team contact list with the estimate plan and/or as part of an estimate responsibility matrix is
recommended.

Word-processing software is best suited for documenting the estimate plan. It can be supplemented with
spreadsheet software for more complex tables and numerical/date information management. For
complex projects, scheduling software is suggested for planning the specific work activities necessary to
complete the estimate including the estimate plan, estimate basis, and deliverables to estimating. The
estimate planning and development activities should be an integral part of the project schedule for that
phase.


Estimate Plan Reviews

Once a draft estimate plan and corresponding schedule are complete, a set of review meetings are held
with all key stakeholders to communicate any defined requirements and responsibilities. It is imperative
during this review that everyone with a key deliverable commits to meeting their assigned dates or else
the entire plan will be in jeopardy of slipping, including the final due date to the owner. Issues and
concerns relative to the estimate plan are documented along with plans to resolve them.


Estimate Plan Approval

Once an estimate plan is satisfactory to the owner, the authorized owner and contractor representative(s)
should endorse it with signatures to indicate alignment and approval. Preferably, this occurs after other
key stakeholders have signed to indicate buy-in and committed to be accountable.

Upon approval of the estimate plan, roll-out sessions are held to communicate the approved basis for
proceeding with estimate development.


Estimate Development Process

A good estimate plan will make the estimating process more efficient. If conditions change significantly,
updates to the estimate plan are necessary to maintain alignment. Changes are integrated and dealt with
through the project change management process.

The final version of the estimate plan may be used as the starting point for the basis of estimate by
carrying over common elements and wording from the estimate plan. Preparation of the basis of estimate
document while the estimate is being prepared is preferred to completing it after the estimate when time
is short and key information may have been forgotten or gone missing along with personnel that are no
longer available.


ESTIMATE PLAN FORMAT AND CONTENT

The extent to which each of the sections below can be completed as indicated is highly dependent on the
level of definition available. Since it is a recommended practice to define as much of the project as
possible up front, that is assumed to be the case. It may be necessary to explain what information is not
available at the time of estimate plan preparation, when it will be available and how it will be handled.
Alternatively, there may be a plan to update the estimate plan at an appropriate point before substantial
work is done on the estimate. Be aware that if several "workarounds" are planned, it may be a sign there
is misalignment between available project definition and estimate objectives.


Purpose of Estimate

The purpose of the estimate sets the focus for the remainder of the document. Summarize what the
estimate will be used for and by who. For example, describe the overall facility type and location. Identify
whether the estimate is a part of requirement for approval to proceed to the next phase of the project
(i.e.: AFE, company-specific stage gate, etc.), a special study, to update the cost control baseline and so
on. Secondary purposes are to establish a basis for project control, to quantify resource requirements
and provide owner decision-makers with an appropriate level of confidence in the estimate.

Based on level of project definition, state the expected accuracy range and AACE International Estimate
Class[7]. (E.g.: It will be a Class 3 estimate and the final cost is expected to be within -10% to + 15% of
the estimate after applying contingency.)


Key Estimate Development Milestones

As discussed above, the estimate plan activities should be an integral part of the project schedule for that
phase. The detailed estimate plan schedule is discussed later in the document. A table of the key
deliverables and planned dates based on the detailed schedule of the estimate plan should be prepared
for management summary purposes. The table may be expanded to contain details such as the expected
status of each deliverable or an estimator site visit. Table 1 is provided as an example. The table may be
extracted for reporting estimate development status to management by adding a column for actual date
completed.

Project Scope and Execution Plan Summary

Summarize the project scope and execution plan for each project phase and make reference to the
primary documents. Identify each process unit, offsites, utilities, subsurface facilities, etc. Indicate
capacities and any other significant factors such as contracting, fabrication and modularization strategies.
Explain the labor type (union, open shop, mixed, or other) and quantify expected sources (number of
local, travel cards, temporary foreign workers, etc.) Provide an estimated overall progress completion
percentage for engineering at the estimate cut-off point.


Construction, Fabrication, and Operating Parameters

Refer to an authoritative source of average annual weather conditions at the job site along with
maximums, minimums and time of year they occur. Corresponding design basis criteria such as
pressures, amount of alloy materials, minimum and maximum ambient design temperature should be
stated. Known soil conditions are summarized (e.g.: clay/rock, topsoil depth, permafrost, water table,
underground aquifers, etc.) Distance to nearest major population centers, infrastructure availability, and
distances are worth stating.


Project Execution Schedule Basis

At the estimate planning stage, a summary execution schedule (by facility, phase, unit, and
commodity/discipline) is included with the estimate plan. Any special schedule events that impact costs
are shown on the schedule and/or described further in the narrative. Examples are: weather windows
(shipping and site); operating plant outages; tie-ins: shift work; extended overtime; union contract

expiration dates; peak manpower periods; planned downtime (e.g.: holidays, planned evacuations in
existing facilities); and known and pending regulatory/environmental issues.


Estimating Methodology

Cover items such as estimate type (capacity ratio, equipment factored, detailed, etc.) Refer to the
expected accuracy range stated in the purpose section and summarize how it will be accomplished with
any applicable discussion of risk analysis to be completed.


Estimating Software

Describe all software and versions to be used including how it is to be used. (E.g.: simulated quantities,
internal database, interface software to load productivity rates into estimating program, etc.)


Coding and Formatting

Attach project code of accounts and project work breakdown structure (WBS) or other specified coding
and formatting requirements as an appendix to the plan or refer to it. The formats to be used in
presentation of the estimate should be clearly identified and agreed with the owner before starting the
estimate. This includes the detailed and summary forms. The cost estimate must show all calculations.
Quotes from vendors and in-house cost databases do not necessarily need to be included with the
estimate but should be referenced and available for viewing by the owner throughout the life of the
project. As a minimum, the detailed forms will contain quantities, unit of measure, hours per unit, labor
hours, labor cost per hour, labor cost, material cost per unit, material cost, equipment cost per piece, and
total equipment cost. Subcontract units, hours, and costs should be broken down in the same manner to
determine camp space (if applicable) and worker densities.

Cost estimate summaries may be specified by the owner. Costs for each inside battery limits (ISBL)
process unit as well as outside battery limits (OSBL) costs should be separated. Allocation of indirect
costs to each ISBL unit and OSBL unit for estimating purposes depends on the execution strategy. If a
single contractor is involved with more than one process unit, then indirect costs should be separated by
the contractor. If a contractor is only responsible for one process unit, the indirect costs will be part of the
total costs for that unit.


Filing Structure

The estimate material including all backup is to be primarily filed and maintained according to the WBS
and code of accounts referenced in the Coding and Formatting section. Other information is to be filed
according to the format of the estimate basis. Additional sections may need to be created for the
following:

Request for Proposal
Review Comments and Minutes
Competition
Drawing List

Miscellaneous


Units of Measure

State the type of units of measure (i.e.; metric, imperial) and any exceptions that may apply.

Currency and Exchange Rates

State the currency to be used (e.g. US Dollars - USD). Indicate the exchange rates for foreign purchases
as applicable.


Process Equipment Pricing

Indicate expected rough percent of equipment costs to be based on budget quotes, firm bids, in-house
pricing or other basis. This varies depending on desired estimate accuracy and level of engineering
development. A summary of the bidding process may be included such as minimum number of bidders,
how bids are normalized for evaluation purposes including exchange rate basis of foreign currencies and
bid validity periods. The planned method of estimating shop inspection, testing, witnessing, and related
travel requirements should be described. Identify whether electrical and instrumentation/automation
equipment are covered under the respective bulk commodity material sections. This should be consistent
with the coding/formatting requirements. Freight and vendor representatives for construction,
commissioning, and start-up should be separately identified whether or not they are part of the equipment
account. Specify whether ladders and platforms will be included with the equipment, "dressed" onsite or
offsite and other similar clarifications. E.g.: equipment insulation is in bulk materials if not supplied by the
equipment vendor. Provide a current version of the equipment list with targeted items for firm quotes
identified. A "priced equipment list" should be specified as an estimate deliverable. Discuss how any
design allowances for equipment will be developed such as guidance from the discipline specialists,
project execution and procurement personnel. Design allowances for equipment are discussed here and
included with the table of bulk commodity material allowances shown in Appendix A.


Spares

Spares require consideration of financial accounting rules and operating philosophy. This includes freight
for spares when practical to separate.

Capital spares should be identified by individual piece of equipment. Refer to owner definition of capital
spares.

Explain the basis for estimating commissioning and start-up spares such as vendor recommendation or if
it will be done by the start-up team. Refer to owner definition of commissioning and start-up spares.

Operating spares and initial stores stock inventory should either be identified as excluded or included as
directed by owner. Agreement with the owner accounting controller is advised regarding categorization of
spares, initial stores stock, and non-capital expense ("OPEX") versus capital ("CAPEX").

Describe how the costs will be determined for each type of spare such as historical data, reference data
and/or discussion with discipline specialists or experts.


Non-Process Equipment Pricing

Refer to the project code of accounts as a guide for segregation of process equipment versus non-
process equipment purchased for use during operation of the permanent facilities. Mobile equipment
(front-end loaders, bucket wheels, excavators, etc.); rolling stock (rail locomotives, cars, etc.); cranes;
personnel vehicles (cars, vans, busses, etc.); maintenance vehicles (flat bed, fork lift, man lift, bundle
pullers, etc.); emergency vehicles (fire truck, foam wagon, ambulance, etc.); fire protection and safety
equipment (extinguishers, hose reels, etc.); lab equipment; office computers; supply boats; and so on.

Vendor Representatives

Identify separately vendor representatives estimated for each piece of equipment or tagged item. If it is
an overall allowance then state the basis for the allowance.


Bulk Commodity Material Quantities

For each commodity, describe the methods to be used such as: detailed material take-offs, based on
sketches, standard detail designs, computer-simulated take-offs, or factored. The extent of planned input
from vendors, discipline specialists/experts and project execution personnel should be stated. The
portion of quantities expected to be available from a 3D computer design model are provided as
applicable for each commodity. Examples of further details needed to adequately explain quantity basis
for each commodity are provided in Appendix C. A table summarizing the planned quantity development
and take-off basis for each commodity can be a helpful quick reference as shown in Appendix B.


Bulk Material Quantity Take-Off Allowances (Design Development Allowance)

Material take-off allowances are based on an estimate of the known but undefined quantities. For each
commodity, describe the rationale for estimate allowances in relation to the level of engineering definition
and the methods to be used to develop quantities. A table listing the estimated allowance for each
commodity and percentage of the base is to be included for quick reference. Refer to Appendix A.


Bulk Material Construction Waste Allowances

Explain the basis to be used for construction waste allowance (e.g.: discussion with specialists, historical
data) by commodity. For quick reference, this is shown with design development allowances in a
summary table. Refer to example in Appendix A.


Bulk Commodity Material Pricing

Indicate expected percent of bulk material costs which will be budget quotes, firm quotes, in-house
pricing or other sources. Include basis for equipment (process, non-process, electrical, instrumentation)
shop inspections and testing. Separately address material supplied to fabricators and material for site
installation. A table could be used to summarize this as well.

Address any special considerations such as whether a concrete batch plant will be used at site.


Offsite Fabrication

The planned amount of offsite fabrication of bulk materials (if available) and the estimating methodology
should be explained (e.g.: unit rate, by weight, by pipe class, fabricator quotes, etc.)


Offsite Module Assembly

Describe the extent of offsite module assembly planned to be done and the geographical locations of the
assembly facilities. Briefly discuss whether modules are placed directly on foundations or at an interim
staging area for further work to be done before moving to final location. Provide the basis for estimating
module yard labor hours and cost rates. Address assembly of pipe rack modules and equipment modules
here. Equipment purchases and "skid packages" are covered under equipment.

Freight

Cost of freight for process equipment should be identified separately from other freight. Indicate how
domestic freight for bulk material will be calculated. Describe availability and pricing source of special
module transportation equipment and other "heavy hauls". Reference the discussion above regarding
placement of modules directly onto foundations and impact on freight cost. Foreign freight costs should
clearly state how the ocean-, air-, and land-based shipping are to be priced as well as any export
preparation/crating and applicable duties.


Construction Labor Productivity

Explain how labor productivity will be determined for each commodity and equipment. It should address
items such as: adjustments to a base productivity for labor density, facility complexity, excessive
overtime, weather, shifts, labor quality, labor availability, worker facilities (e.g.: lockers, washrooms,
lunchrooms) proximity to ISBL and OSBL work areas and support facilities (e.g.: tool crib, warehouse,
material staging area), greenfield versus brownfield versus revamp versus shutdown conditions, soil
conditions, elevated work, geographic location, and any other factors affecting productivity. Provide a
description of the base productivity including the types of projects included, such as company USGC, 3rd
party software database, in-house data, etc. A table should be provided in the estimate plan showing how
each factor will be applied and its affect on the rate to be used in the estimate.


Construction Work Week and Overtime

Indicate the construction work week basis and applicable shift schedules (e.g.: 8 hours per day x 5 days
per week.) Explain how overtime hours and related cost allowances will be determined.


Construction Labor wage rates

Describe how crew mixes, union contracts, non-union wages, benefits and other factors will be used to
build-up the labor rates. Obtain a copy of the craft labor agreements when available. Crew mixes
includes portions of apprentices, foremen, general foremen, journeymen. For each commodity, crew mix
also refers to potion of total for each trade (e.g.: pipefitters, welders, carpenters, electricians, etc.)


Construction Subcontracts

It is preferable to quantify all subcontractor hours for construction infrastructure planning and worker
density analysis purposes. Subcontractor materials are to be separately identified as owner, contractor,
or sub-contractor supplied. State the construction strategy pricing basis (unit-price, lump-sum, etc.) for
each subcontract. E.g.: piling based on firm unit rates including aggregate and all embeds but excludes
pile caps and dewatering beyond a predetermined amount; insulation based on budget quotes; painting
is included with steel, pipe and equipment pricing except field touch-up which will be based on in-house
data; and so on.


Construction Indirect Costs

The cost basis for construction indirect costs should be broken down according to the code of accounts
as per the following example:

Construction Management To be developed using a personnel plan by position or by discipline spread
over the project duration. Explain how office and travel costs are covered including courier, temporary
office furniture, office equipment, supplies, computers, and telephone charges. Consider design and

drafting be done at the construction site including as-built drawings. Specify what is part of the as-built
scope e.g.: process flow diagrams (PFD); process and instrument diagrams (P&ID); undergrounds;
junction box wiring diagrams; single line diagrams; load lists; schematics; 3D model updates; etc.
Personnel costs are normally kept separate from office costs in detail cost accounts but they may be
discussed together in the estimate plan. Construction insurance may be included here if it is not covered
by owner project overheads. Bond costs may be included if applicable.

Camp (if applicable) Identify who will stay in the camp and related construction manpower peaks.
Include catering and what is to be part of the price such as lunches for personnel not staying in camp,
whether any utilities (water, gas, power, etc.) are part of the cost. Consider whether it will be pre-fab, built
on site and if personnel will be housed single, double, or otherwise. State amenities to be included such
as laundry facility, exercise room, indoor/outdoor recreation, etc.

Temporary Facilities - Describe onsite or offsite locations for temporary buildings, roads, parking,
laydown areas and material staging, etc. State how requirements for temporary offices and other facilities
will be determined. Document any existing utility facilities available for construction use and/or source.

Utility Consumption It is recommended utility consumption (gas, power, water, sewer) be kept separate
from the related facilities cost for estimating and control purposes. These costs can vary significantly and
may be provided from various sources such as existing plant, temporary facilities, and/or new permanent
facilities. Identify construction power requirements for electric welding machines, warehousing,
construction offices, parking lot lighting and plug-ins, onsite fabrication shops, etc. The same applies for
fuel, gas, potable water, and sewer.

Temporary Services Note any special safety requirements and who is responsible (e.g.: Nomex, gas
sniffers, fire watch, etc.) Weather protection may be based on a percentage of concrete and piping per
historical data. An allowance for general site dewatering will be based on average annual rainfall and
water table data. Drinking water supply source and pricing basis are described.

Construction Equipment Typically, a table is developed showing monthly requirements for cranes, man
lifts, and other construction equipment. Availability and pricing basis to be used for cranes should be
discussed. Describe the number and type of cranes needed for heavy lifts. Include freight/shipping, and
mobilization/demobilization. Include assembly/disassembly if not covered elsewhere.

Small Tools Delineate how cost of small tools is allocated between indirects and subcontractor rates as
applicable. A brief discussion of the source (e.g.: tool crib rental, purchase, etc.) should be included.
Refer to any definition of small tools. Discuss small tool replacement and repair requirements.

Scaffolding Explain whether scaffolding labor will be factored from specific direct accounts based on
historical data and adjusted for height in conjunction with discussion with construction specialists.
Scaffold material requirements basis is provided by construction and/or historical data.

Consumables Provide basis to be used in estimating consumables and refer to any definition of
consumables including differentiation with "construction aids" which tend to be consumable over the life
of a long project but re-usable within that time. E.g.; tarps, rope, etc.

Craft Benefits and Burdens - Normally part of the craft wage rate build-up but may be separately
identified if required by the owner or contractor estimating methodology and execution strategy. Obtain a
copy of the craft labor agreements for determining benefits and special conditions such as: mileage
payments, health care expenses, payroll taxes, workers compensation, etc.


General Demolition

This addresses general demolition of decommissioned and/or abandoned facilities. Demolition for
revamps is typically included with each commodity/discipline. Describe the general demolition scope and

how it will be estimated. Where possible, it should be based on field-verified quantities and quoted
subcontract rates. The owner should provide any direction required on treatment of expense versus
capital for demolition.


Commissioning and Start-Up

Explain how commissioning and start-up costs will be determined and briefly describe the related scope
(e.g.: crew-based, factored from historical data, etc.) Refer to owner-approved definition of mechanical
completion to distinguish between commissioning work and construction work. Reference spares
discussion above. Quantities of initial fills of lube oil, heating/cooling mediums, chemicals, etc. to be
estimated by process group based on equipment sizing, vendor information, and process conditions.
Catalyst and packing pricing may be based on discussions with licensors, engineering contractors, and
vendors.


Engineering and Home Office Hours

For each discipline, describe how the labor hours will be determined (e.g.: deliverables, commodity
quantities, time-based, etc.) Estimating of work week and overtime for head office personnel should be
discussed. Include construction support to home office, home office support to construction, engineering
site visits, vendor shop inspections, start-up support, preparation of operating manuals, engineering
services such as reliability and maintainability (RAM) studies, heavy lift studies (if applicable),
environmental consultants, HAZOP (hazardous operations reviews) facilitators, constructability
consultants, module coordinators, etc. State whether field engineering and site based "as-built drafting"
work are included with construction indirect costs. Project management may be separately addressed
depending on how the cost account structure is organized.


Engineering and Home Office Costs

Show how the engineering labor rates are to be built-up. Describe how other office costs and fees will be
covered and refer to any contracts in place. Identify prior project phases to be included in the estimate
such as front end loading 2 (FEL2) and FEL3.


Clarifications, Qualifications and Assumptions (to be included under discussion of each commodity or in
general)

Clarifications and assumptions which apply to more than one commodity or are more effectively identified
separately are addressed in this section. The rationale for any assumptions to be used should be
provided. Consider the items in Appendix D which are often omitted but should be clarified. This section
may be combined with Exclusions.


Exclusions

Contractors often state anything not specifically identified is assumed to be out of scope. Owners assume
everything required is included in contractor estimates unless they have specified otherwise. Neither
approach provides sufficient information to prepare a good estimate. All known estimate exclusions
should be listed with an explanation of why. For example:


Financing charges will not be included because they will not be allocated back to the project.
Operating and maintenance spares are excluded. They will be purchased by operations.

Recoverable taxes and duties are excluded (identify which taxes e.g.: sales tax.) These costs will
be paid by the project but credited upon recovery.

Owner Costs

Do not create a separate section for owner costs. Owners may execute all of the project scope or none
and all options in between. Therefore, owner scope should be addressed in the appropriate section of
estimate plans or clarified in contractor estimate plans by listing each specific owner scope item
excluded. Refer to Appendix H for typical items to be clarified for each estimate.


Late Changes

Explain how late changes subsequent to the estimate cut-off date will be handled. A log should be kept of
all changes and integrated with the project change management procedures. The log will be part of the
estimate package. Consider any owner formatting requirements for late changes.


Escalation

Include a description of escalation calculations and sources. As a minimum it should be broken down into
the major categories of equipment, bulk material, construction labor, and engineering. Known wage rate
increases after the point in time of the estimate basis are covered by escalation and should not be
included in the base estimate to maintain consistency.


Risk Analysis and Recommended Contingency

Contingency is typically recommended by contractors but determined by owner management based
primarily on the results of the cost estimate and schedule risk analyses. State the software and
methodology to be used. A different contingency may be appropriate for each process unit or area of the
facility due to varying levels of definition and confidence in the base estimate. A summary of the risk
analyses results should be included in a separate section of the basis of estimate with a cost risk profile
chart. The chart should show the P10, P50, expected value and P90 points on the curve or other points
specified by the owner. On larger projects, a tornado diagram showing the top ten risks and opportunities
may be included.


Benchmarking

As part of the estimate review and validation process, benchmarking should be performed. The intended
source(s) of benchmark data is stated as well as the metrics to be used in benchmarking. Key metrics
should be included with the estimate basis for quick reference. These will vary depending on the class of
estimate. Refer to Appendix E for an example list of metrics.


Cash Flow/Cost Flow

Provide a sample cash flow in table format according to the intervals required by the owner (monthly,
quarterly, etc.) Describe how the cash flow will be determined for each category breakdown such as:
historical data, project-specific progress and manpower profiles, standard payment terms, etc.


Estimate Development Schedule

The estimate development schedule should be an integral part of the project schedule for the applicable
phase. For large projects, it will be within a CPM schedule which can be used for integrating the estimate
plan with other phase deliverables and for tracking. This approach keeps focus on the engineering and
execution development activities required to meet the objectives for that phase and the desired estimate

accuracy. AACE International RP 18R-97 (Cost Estimate Classification System As Applied In
Engineering, Procurement, And Construction For The Process Industries)[7] provides a summarized
estimate input checklist and maturity matrix. A detailed estimate development schedule is produced to
show the timing of activities required. Refer to Appendix F for example list of activities shown in no
particular order.


Estimate Responsibility Matrix

An estimate responsibility matrix is a useful tool in planning and managing the key estimating
deliverables. Develop a matrix indicating which documents will be used in the estimating process, who
will provide them (including organization), the expected level of completion (i.e.: preliminary, IFD, etc.)
and the date. The matrix can be an extract from the project schedule or in spreadsheet format. Providing
contact information for each person shown in the matrix is helpful. Refer to Appendix G for an example
matrix. An improvement to this format would be to add a column for who will estimate the items.

APPENDIX C Examples of Planned Bulk Material Quantity Basis

Earthwork and Site Work Reference geotechnical data, topographical drawings, or photogrammetric
maps, to be used. State whether tree/brush clearing/grubbing is required in addition to topsoil removal
and general cut and fill operations to level site. Explain whether excavation and backfill quantities are to
be developed from standard foundation details, underground trench sketches, or other method. E.g.,
dewatering for excavation of permanent facilities will be a percentage of excavation of backfill quantities.
Address whether quantities will be generated for permanent fencing, signage, and landscaping and how.
Similarly discuss road, railway, and marine work.


Piling Explain how quantities are determined for each type of pile. E.g., diameter and depth for drilled
caissons. Include any clarifications for quantifying rebar, aggregate, sonotube, etc.


Concrete Reference any standard foundation designs which may exist and describe how quantities are
developed for cast in place concrete formwork, insulation, aggregate, embeds (rebar, anchor bolting,
etc.) Also address specialty items such as curing agents or cementitious grout. Explain any strategies
regarding quantities of pre-cast concrete whether purchased or precast at site. Reusable forms may be
addressed here or in indirects depending on the code of accounts in effect.


Structural Steel Separate module assembly quantities from site-installed quantities. If MTO's are
desired by light, medium and heavy this needs to be stated. Define whether tube-shape pipe supports
are part of piping quantities or structural steel account.


Buildings Sizing basis such as equipment layouts/sizes shown on issue for design (IFD) revision of plot
plan. Determine extent of furnishings and fixtures included for each building as well as single or multiple
floors. Categorize buildings as process, electrical, maintenance shops, warehouse/storage or
administration for estimating and financial treatment.


Piping Define the sizes included in small bore versus large bore piping (e.g., >2") and criteria for
physical allocation of bulk material across more than one process unit (e.g., 1st valve downstream,
exactly at battery limit coordinates, etc.) Reference specifications, P&ID's, plot plans, and routing basis
used for determining lengths. State that steam trace tubing length calculation basis excludes "hard piped"
supply/return lines and headers for clarity. Provide rationale for factors to be used in determining steam
tracing, small bore, shoes, guides and hangers.


Electrical State expected use of equipment load list, single line diagram and area classifications. If
instrument wiring is part electrical account, include basis such as I/O count, instrument count and routing
used for determining lengths. Refer to wire and cable specifications. State junction box location
assumptions for quantifying terminations. Electric heat tracing specifications should state how equipment
and piping (by pipe spec/size) affect tracer type and routing as well as controllers.


Instrumentation Identify revision of P&ID's to be used for instrument counts, control systems, panels,
etc. Clarify whether items shown on P&ID's within vendor packages are part of vendor pricing and extent
to which the related wiring or tubing are part of vendor packages. If vendor supplied, state if already
installed in "package" (only requiring testing & calibration where applicable) or if vendor supplied but
shipped loose, for contractor to install. All other quantities are assumed to be required from vendor skid
back to control points or junction boxes. State the basis for any allowances for installed spares and spare
card slots. Sizing of control systems may be from I/O count or vendor.

Painting State how field and touch-up painting will be quantified (e.g., factored based on historical
data.)


Fireproofing Explain whether any structural steel or vessel fireproofing is required and if it will be
applied at site or in vendor's shop or at site. Outline how any site cast fireproofing will be quantified.


Insulation Describe the methods to be used for equipment and pipe insulation with reference to
specifications (blanket, formed, material, jacket, removable, valve/flange covers, etc.)
