APPENDIX C

Florida and Virginia DOT Open Book Cost-Estimating Requirements

The following is an extract from a Florida DOT “Marion County ITS Operational Improvements – CMGC Services Request for Proposal.” It is included as an example of FDOT’s approach to open-book cost-estimating verbiage that could be included in CMGC and PDB RFPs to define the process.

1. INTRODUCTION

Throughout the Pre-Construction Phase, and as changes demand during the Construction Phase, the CMGC shall provide estimates of Project cost and/or cost of individual Project elements. The estimates shall be prepared in a transparent, detailed, open book format that allows the Department and their representatives to understand the basis of costs and cost development.

The estimates shall be prepared in the Contractor’s cost-estimating system as is customary use by the Contractor for other projects of similar nature. The estimates are to be developed using current pricing for wage and equipment rates (material pricing will depend on how the material was quoted and the amount of time for which the quote is fixed). Since some estimates will not have the pricing for all material suppliers and subcontractors to enable firm fixed pricing for use in the Lump Sum (LS) Price, there may be limited items of plug pricing, which should be noted as such.

As the estimates are successively refined, the plug pricing will be replaced by firm prices in using competitively selected subcontractors and materials suppliers. All subcontractor estimates are also subject to the Open Book Estimating requirements. Submitted estimates shall clearly itemize the estimated costs of performing the Construction Work of the items in the mutually agreed schedule of values and also include the Contractor’s field indirect items. A summary-level cost is requested for each of the items provided, supported by a detailed cost of each item. The detail shall provide crews with rates of production for each activity within the item of Construction Work.

Crews shall clearly show the numbers of equipment and personnel within each activity and work hours for overtime calculations. Estimates of cost for items of Construction Work shall be further divided into the Contractor’s customary cost categories such as man-hours, labor, permanent materials, expendable materials, equipment ownership and operation, and subcontract cost, as appropriate.

The detail of the Construction Work breakdown may include several activities within a schedule of value line items that shall subtotal to a one-line entry for the summary report. The summary shall include the same cost categories along with the unit cost of the total. Further groupings of similar items of Construction Work can be agreed upon to further facilitate reconciliation of the Department and CMGC estimates. Costs and price for the project shall be subdivided as follows:

  • Total Construction Phase Costs composed of direct costs attributed to item quantities appearing in the plans and field indirect costs
  • Mark-up expressed as a percentage of total Construction Phase costs per the contract terms

2. TOTAL CONSTRUCTION COST ELEMENTS

  1. Direct Costs. Enter the direct costs for performing the Construction Work on the forms provided using the estimated quantities. Direct costs of the items of Construction Work shall not include:
  • Any contingencies
  • The spread of field indirect costs
  • The Contractor’s profit and home office overhead (The Department has established a fixed-markup percentage of 12 percent for this project).

The items of Construction Work shall include the direct cost of performing the Construction Work only. The schedule of values line items list will be developed in conjunction with the designer and required specifications including measurement and payment are as specified by the standard provisions. This may not be an all-inclusive list of the Construction Work to be done for a section but includes the major items of Construction Work for cost development.

  1. Field Indirect Costs.
    1. The Contractor’s field indirect costs shall be included in the Total Construction Phase Cost. The list below shows a sample breakdown of indirect cost categories that is acceptable. However, it is also acceptable to use the Contractor’s own customary indirect template with an explanation of the costs included within each item if the level of detail is similar to that shown below. Field indirect shall include costs for the following:
    2. Job Supervision and Overhead: Wages, including benefits, payroll insurance and taxes for onsite management, supervision, engineers, safety personnel, quality control staff, and administration staff
    3. Survey: Cost of construction survey including both Contractor-hired and outside services
    4. Site Office Expense: Ownership or rental of building, maintenance, removal, utilities, office and engineering expendables, furniture, computers and infrastructure, and photographs
    5. Insurance and Taxes: Insurance other than that based on payroll, such as railroad protective, equipment insurance, and other specified or Contractor-required insurances; taxes, excluding payroll taxes such as property tax and any special local or State sales tax, should be included with the applicable item taxed.
    6. Temporary Buildings: Cost of ownership or rental, set up, maintenance and removal of such as warehouses, first aid building, and other miscellaneous
    7. Personnel Expense: Small tools and supplies (unless carried in the direct cost portion of the estimate), safety expendables, drug screen testing, training, physicals, hiring expense; include any per-diem costs for craft or indirect personnel
    8. Project Utilities: Site utilities such as temporary electric, water, and sanitation
    9. Mobile Equipment: Overhead vehicles, maintenance equipment and personnel (if not in Equipment Operating Expense), and general service equipment (e.g., flatbeds and forklifts) and personnel if not in the direct cost
    10. Mobilization: Cost of transportation of equipment and other items for move in, move out, set up, and take down, including cost of personnel moves and related expense

    1. Construction Plant: Site fences, parking areas, material yards, temporary access, and other such special construction not included in direct costs; haul road construction and maintenance to be included in direct costs
    2. Quality Control: Cost of Quality Control labor, equipment, supplies, outside services, and Contractor-hired personnel and on-site quality supervision
    3. Bonds: Cost of payment and performance bond or other guarantees as specified or allowed, if any; also includes cost of subcontract or material bond
  1. Allowable Construction Phase Costs for Direct and Field Indirect Costs. Definitions of some of the items of direct and field indirect costs are set forth below and shall not be included in the mark-up:
    1. Labor: Wages and add-ons, including overtime, vacation pay, and all fringe payments such as health and welfare, pensions, and any other that may be included in union agreement or as paid to both craft and staff employees; payroll insurance including Worker’s Compensation and General Liability if based on labor amounts; payroll taxes including Federal Insurance Contributions Act (FICA) and State and Federal unemployment
    2. Permanent Materials: Cost of materials incorporated into the Construction Work, including estimated loss, waste, and non-pay overruns; sales tax and any shipping for these materials will be a part of this category
    3. Construction Expendable Materials: Non-permanent materials, temporary facilities, small tools, formwork, temporary construction, office supplies, services, insurance, and taxes
    4. Equipment Ownership: Rental or ownership charge of both company-owned and outside rentals, and tax on any rentals
    5. Equipment Operating Expense: Repair parts, tires and tracks, Contractor’s repair labor, services and fuel, and oil and grease
    6. Subcontract: Cost of items of Construction Work subcontracted, including contracted trucking
  2. Use of Construction Cost Estimate. The detailed cost estimate will be the basis of developing estimates during the Pre-Construction Phase and for preparing the LS Price. Total the direct and field indirect costs separately. The same cost-estimating model, with the same transparency and level of detail, shall be used and submitted for cost proposals for Early Works, the LS price proposal, and as construction changes, or additional work warrant for change proposals (Supplemental Agreements) during the Construction Phase.

3. MARK-UP and LS PRICE

The Contractor shall use the mark-up established in the contract at 12 percent of the Total Construction Phase Cost. The Fixed Mark-up Percentage will include the Contractor’s profit and the portion of home office overhead (G&A) allocated to the project. The Fixed Mark-up Percentage defined in the contract will be used in the preliminary and final LS Price Proposal.

The profit component of the mark-up excludes any agreed upon bonuses and incentives as part of Phase 2 work. Home office overhead (G&A) is defined as all auditable costs that are allocated to

all of the Contractor’s ongoing projects, such as off-site supervision and travel expenses for offsite supervisors, attorney and counsel fees, and insurance that is maintained by the Contractor as a general cost of doing business. The fixed mark-up does not include any field indirect costs or direct costs of the Project. The mark- up percentage shall be applied to the total Construction Phase Cost and the result shall be the LS Price Proposal. The mark-up percentage shall also be applied to any change proposals (Supplemental Agreements) during the Construction Phase.

4. NARRATIVE

Along with the estimate reports, provide a summary narrative of the estimate. Include a discussion of how specific items were developed in the estimate, such as, but not limited to, fuel pricing, material sources, labor rates, any craft labor agreements, and availability of skilled craftsman. Discuss approach to equipment availability and rental rates, including any equipment adjustments to hourly equipment rates used in the estimate based on schedule usage of equipment versus length of time equipment will be on the job, or if a buy-sell basis of ownership costs is applicable to the Project. Discuss which material and subcontract pricing is firm, which uses plug prices, and the expected variability of such pricing. Discuss temporary construction required such as haul roads, detours, any retained earth, and borrow or waste pit development. Discuss approach to schedule, including hours of Work, double or triple shifts, weather and season considerations, and the general duration of the estimated Work.

Virginia DOT
Opinion of Probable Construction Cost (OPCC) Process

One of the most critical steps prior to successfully validating the lump sum price for Phase 2 services on a PDB contract is to require the Design-Builder to submit their estimate for the cost of the work at various pricing milestones as the design progresses. The Design-Builder shall submit an estimate to VDOT at each pricing milestone using the Opinion of Probable Construction Cost (OPCC) process. Level of efforts for the OPCC process will vary depending on the Phase or level of plan development.

Pricing milestones will occur at the time the Design-Builder submits a proposal and associated cost estimate to the Department. Pricing milestones allow VDOT to review and resolve pricing disagreements early in the PDB process, rather than wait until the end when the Phase 2 Proposal is submitted. Pricing milestones may occur:

  • At the conclusion of Phase 1A prior to submittal of the Design-Builder’s Phase 1B Proposal
  • During Phase 1B as design development progresses (i.e. 30% or 60% plan development)
  • Acceptance and execution of Early Work Packages (if necessary)

VDOT will accomplish validation of the cost estimate by comparing the Design-Builder’s cost estimate for the work with the cost estimate developed by an Independent Cost Estimator (ICE) and VDOT’s Estimating Engineer (EE). After each pricing milestone, VDOT and the Design-Builder will reconcile cost and scope using an open book basis.

Task 1: Cost Model

Successful price reconciliation in PDB relies on the ability of all parties to thoroughly understand the basis of the Design-Builder’s cost estimate. It is critical that the Design-Builder clearly documents all assumptions, pricing and labor rates that were used to price the work. This documentation is maintained to capture a history and basis of pricing changes. To this end, the Design-Builder will be expected to be open and transparent about how the work was estimated.

The cost model shall include a narrative summarizing the key pricing assumptions for each OPCC. The cost model narrative includes such things as: type of equipment proposed to perform the work, assumed production rates, crew sizes, shifts per day, hours per shift, risk assumptions, assignment of risks, assumed weather delays, and supporting subcontractor quotes. Other assumption regarding risk (assumptions and/or assignment), weather delays, and ancillary factors will also be documented. The cost model shall be updated by the Design-Builder prior to developing each estimate.

Task 1A: Estimating Instructions

Estimating instructions and guidelines are included in Exhibit 1. These instructions outline how the estimates will be developed between multiple estimating parties. This ensures that all parties are using the same format for work products and facilitates consistency between different estimating teams and cost comparisons during pricing reconciliation.

Open-Book Pricing Practices for Construction Manager/General Contractor and Progressive Design-Build Projects. Washington, DC: The National Academies Press. doi: 10.17226/29084.
Task 2: Estimate Workshop

The Design-Builder shall schedule and lead an Estimate Workshop prior to issuance of each Estimate Package. Workshops attendees should include at a minimum the VDOT PM, EE, ICE, and technical experts who have insight into the project (e.g., geotechnical, bridge, construction, environmental, etc.).

The objective of the Estimate Workshop is to:

  1. Ensure a constructible and cost-effective design that is consistent with the design intent,
  2. Ensure that the design complies with standards,
  3. Endeavor to confirm that all work has been included and described in sufficient detail for that stage of design to ensure complete pricing of work,
  4. Allow all parties to provide feedback on the constructability of the plans,
  5. Discuss assumptions on means and methods, and construction staging or sequencing of work that affects cost,
  6. Reconcile quantities between the designer and estimators,
  7. Identify any errors, omissions, ambiguities, or other items that need to be corrected, and
  8. Identify major project risks, propose mitigating actions, allocate risks to the party who is in the best position to manage the risk, and how risk is influencing the estimate.
Task 3: Estimate Package

The Design-Builder shall prepare an Estimate Package for each pricing milestone identified during Phases 1A and 1B and provide the package to the VDOT PM for distribution to the ICE and EE. Each Estimate Package shall include the estimating instructions, plans, quantity take-offs, proposed pay items, measurement/payment definitions, and any specifications appropriate for the level of design.

Task 4: Preparation and Submission of Estimates

At each pricing milestone the Design-Builder updates the Estimate Package (if necessary) based on input from the Estimate Workshop. The following cost estimates are then independently prepared by the Design-Builder, ICE, and VDOT’s EE:

  1. Design-Builder’s Estimate: The Design-Builder prepares their estimate at each pricing milestone. The Design-Builder’s Estimate is made available to all estimating parties (ICE and EE) and VDOT’s PM.
  2. Independent Cost Estimate: The ICE prepares an estimate for the work at each pricing milestone. The purpose of the Independent Cost Estimate is to validate that the Design-Builder’s cost for the work is reasonable and fair and to help support the Project Team in developing a design that is cost effective. The ICE reports to, and receives oversight from the VDOT PM. The Independent Construction Estimate is made available to all parties, including the Design-Builder, and will be used in comparison to the Design-Builder’s Estimate to reconcile estimates.
  3. Engineer’s Estimate: The Engineer’s Estimate is prepared at each pricing milestone. VDOT’s EE, or a consultant working under their direction, will be responsible for the
Page 118

Open-Book Pricing Practices for Construction Manager/General Contractor and Progressive Design-Build Projects. Washington, DC: The National Academies Press. doi: 10.17226/29084.
  1. Engineer’s Estimate at each pricing milestone. The Engineer’s Estimate is not made available to the ICE or Design-Builder but is made available to the VDOT PM.

Estimates prepared by the Design-Builder and ICE shall be a production-based, contractor-style estimate prepared using typical contractor-style estimating software. Although the estimates are prepared using a production-based, contractor-style approach, costs provided to VDOT should be rolled up into unit costs or lump sum items.

The ICE, VDOT’s EE, and Design-Builder shall each submit their estimate directly to the VDOT PM.

4.1 Subcontracted Work

At early pricing milestones, the estimates may include “plug or placeholder” prices, or estimated costs based on past relevant experience, for the work the Design-Builder intends to subcontract (as noted in their subcontracting plan). As design progresses, the estimates will contain actual quotes for subcontracted work. To ensure competitive pricing for the subcontracted work, the Design-Builder will be required to attempt to solicit at least three quotes for all subcontracted work. If obtaining at least three quotes for any subcontracted work is not possible, the Design-Builder will be required to provide documentation to the VDOT PM justifying why three quotes are not obtainable. The VDOT PM may also request that the Design-Builder consider self-performing the work, if possible, in order to help ensure competitive pricing. Unless otherwise authorized in writing by the VDOT PM, the subcontractor quotes received by the Design-Builder shall only be shared with the EE, ICE, and VDOT PM. The ICE may solicit quotes for subcontracted work in order to independently validate the cost of subcontracted work. Prior to the ICE soliciting any quotes, the Design-Builder and VDOT PM should contact subcontractors to notify them that they may be contacted by the ICE, and strongly encourage them to work with the ICE. The ICE will be allowed to share all quotes with the VDOT PM, EE, and Design-Builder. Ultimately, the Design-Builder is responsible for selecting the subcontractors they use to perform the subcontracted work.

Disadvantaged Business Enterprise (DBE)/On-the-Job Training (OJT)

The VDOT PM will provide updates to the VDOT Civil Rights Division throughout preliminary design in order to inform them about the status of the project. Prior to Phase 1B, the VDOT PM will provide Civil Rights appropriate information to clearly understand the scope of work. Civil Rights will establish, as applicable, DBE and OJT goals prior to any subsequent estimates. The Design-Builder shall update their subcontracting/supplier plan, as needed, and all estimating parties shall account for the goals/requirements for ensuing pricing milestones.

Task 5: Preparation of Variance Reports

During each pricing milestone, the Design-Builder’s Estimate will be compared with the estimates prepared by the ICE and the EE. The VDOT PM will develop a variance report. The variance report shows the Design-Builder’s Estimate and the Independent Cost Estimate. The variance report will not include the Engineer’s Estimate.

Open-Book Pricing Practices for Construction Manager/General Contractor and Progressive Design-Build Projects. Washington, DC: The National Academies Press. doi: 10.17226/29084.
Task 6: Pricing Reconciliation Meeting

The VDOT PM will schedule a pricing reconciliation meeting at each pricing milestone. Price reconciliation meetings will be limited to key VDOT project management staff and estimating staff that are directly reconciling differences between the ICE, EE and the Design-Builder’s Estimate. All participants in the price reconciliation meeting(s) will sign a Confidentiality Agreement stating that they will not disclose any information from the meeting(s). The VDOT PM and the Design-Builder oversee the reconciliation meetings, with the intent to reconcile pricing differences between the Design-Builder’s Estimate and the Independent Cost Estimate. The reconciliation process gives all parties the opportunity to understand each other’s perspectives about pricing assumptions, risk assignment, and construction means and methods. The EE will participate in these meetings but will not disclose their estimate.

The ICE and EE will inform the VDOT PM of any potential cost savings opportunities. The VDOT PM may share this information with the Design-Builder. It is the responsibility of VDOT to help ensure the ICE and EE remain independent during reconciliation meetings.

Once VDOT and the Design-Builder agree upon changes to the pricing assumptions, the Design- Builder will make adjustments to the cost model and the schedule to reflect these changes and resubmit them to the VDOT PM, ICE, and EE. This information is then documented in the project file. Any pricing changes will be carried forth to the next pricing milestone or the Phase 2 Proposal. During the reconciliation process, the ICE and/or EE may adjust their pricing assumptions and estimate as necessary.

6.1 Open Book Process

Open book pricing is a collaborative, transparent cost-estimating process utilized by VDOT and the Design-Builder to achieve a Phase 2 lump sum price below the established Guaranteed Maximum Price. The open book pricing process is used to achieve agreement on final design and construction costs during the Proof of Concept (Phase 1A) and Project Development (Phase 1B) phases of a PDB procurement.

“Open Book Basis” means allowing the Department to review all underlying assumptions, records, stand-alone subcontractor quotes, and other data associated with each element of pricing, or any adjustment thereto, including assumptions as to costs of the work, schedule, composition of equipment spreads, equipment rates, labor rates, production rates, estimating factors, design and productivity allowance, contingency and indirect costs, risk pricing, discount rates, interest rates, inflation and deflation rates, operating costs, burdens, encumbrances, profit, turnover, mark-ups, fees, charges, levies, incentives, and other items reasonably required by the Department to satisfy itself as to the reasonableness and accuracy of the amounts proposed by the Design-Builder.

Through open book pricing, the Design-Builder’s Estimates are negotiated in a completely transparent manner, with none of the costs hidden, embedded, or inflated. Transparency means full, confidential disclosure of all the details and may include third party verification by the Department, if required. The process is truly an open book that provides confidence in the price throughout the process.

Open-Book Pricing Practices for Construction Manager/General Contractor and Progressive Design-Build Projects. Washington, DC: The National Academies Press. doi: 10.17226/29084.

During the reconciliation process, VDOT may ask the Design-Builder to share or review with them certain items or materials containing information that clarifies how the proposed pricing was derived in order to help reconcile differences between the ICE, EE and the Design-Builder’s Estimate. All materials of this nature will be reviewed in an open-book format and remain in the possession of the Design-Builder unless the Design-Builder agrees to release it to VDOT. VDOT may not retain a copy of these materials, either electronic or in hard copy.

Not everything on a project is entirely predictable, especially in the early stages. Undefined risks shall be quantitatively assessed and evaluated as a project contingency amount. The actual contingency should be seen as a project cost before any add-ons are included to create a lump sum price for Phase 2.

VDOT and the Design-Builder may not be able to resolve all price differences for certain pay items or for the overall price during the pricing reconciliation meeting. The VDOT PM and the Design- Builder will decide to (a) acknowledge differences, move forward with design, and attempt to continue reconciling differences during later estimates or the Phase 2 Proposal, or (b) agree that reconciliation is not possible and terminate the contract to allow VDOT to procure the construction of the project through some other method. If there are ongoing work packages at the time of termination, the Design-Builder may be allowed to continue work on active work packages until complete. VDOT’s PDB model closes the open book pricing process after acceptance of the Phase 2 Proposal. The Design-Builder proceeds with final design and construction at its own risk of meeting the agreed upon lump sum price.
