How is federal contractor estimating different from private work?
Federal contractor estimating prices labor from the applicable Davis-Bacon general decision rather than open-market rates, then carries fringe benefits, certified payroll reporting and bonding into the bid schedule. We show each wage rate, quantity rule and arithmetic step so the unit price or lump sum can be checked against the solicitation.
Our Professional Federal Contractor Estimating
A federal solicitation prices differently from a private job. The wage determination attached to the IFB sets minimum hourly rates and fringe benefits by labor classification, and the bid schedule asks for unit prices you must defend later through certified payroll. Our federal contractor estimating starts from those two documents, not from a generic cost book.
Every figure on our sheet carries its rule. A davis-bacon wage takeoff shows the classification, the base rate, the fringe credit and the hours, so a contracting officer can trace any labor dollar back to the general decision. Material takeoff quantities cite the drawing sheet, detail number and the latest addendum, which matters when a revised door schedule lands three days before bid day. If you are weighing which delivery method fits your firm, the overview of the client types we estimate for explains how our sheets are organized for each one.
Quantity takeoffs by MasterFormat division
We measure from the drawing set and specification sections, organized by CSI MasterFormat division: Division 03 concrete in cubic yards, Division 05 metals in tons and linear feet, Division 26 electrical in linear feet of conduit and counts of devices. Each line names the assembly, the unit of measure and the waste factor applied, typically 5% on masonry and 10% on cut flooring. You receive a material takeoff in Excel with a PDF summary and marked-up drawing pages showing where each quantity was taken.
Davis-Bacon labor priced by classification
Labor is priced by classification and by wage determination, not by a blended crew rate. A davis-bacon wage takeoff separates the base hourly rate from the fringe benefit, then adds your actual labor burden for payroll taxes, insurance and small-tool allowance. We build the hours from production rates tied to the measured quantities, so a change in square feet moves the labor line in a way you can audit. The labor cost estimating services page covers how those burden components are assembled.
Cost estimates mapped to the bid schedule
The deliverable is a cost estimate mapped to the government bid schedule: lump sum lines where the schedule asks for a total, unit price lines where it asks for a rate per cubic yard, ton or linear foot. We carry allowances as separate named lines and flag any addendum item that changes scope after the site visit. Each estimate is labeled with its AACE estimate class so the owner knows how much design detail stands behind the number. Send the plans through get a quote and we will confirm the fee after reviewing the solicitation.
What Is Included in Our Federal Contractor Estimates?
A prevailing wage construction estimate is mostly a documentation exercise wrapped around ordinary quantity math. The sheet has to show what was measured, which wage determination governed each hour, and how the bid schedule line was built from those two inputs. Federal contractor estimating keeps those three layers visible on every tab rather than collapsing them into a single price.
The wage determination lock-in is the step most often missed. The general decision in force at bid opening governs the contract, and a later revision does not automatically apply unless the contracting officer issues a modification. We record the decision number and effective date on the cover tab and price every labor line against it. Any RFQ that arrives without a wage determination gets a written note on the assumptions page rather than a silent guess, which is the habit that separates federal contractor estimating from private work.
Wage determinations, classifications and fringe credits
Each labor line carries the classification, the base rate, the required fringe and the fringe you actually pay, because the difference is a credit against the total. Apprentices are priced at the ratio permitted by the determination, and any classification not listed is flagged for a conformance request. The sheet totals straight-time and overtime hours separately, since federal schedules often price them as distinct unit prices.
Measured quantities by spec section
Quantities are taken from the drawings and cross-checked against the specifications: square feet of slab on grade, cubic yards of structural concrete, tons of reinforcing steel, linear feet of conduit and count of fixtures. Openings, penetrations and typical-room multipliers are shown as separate rows so a reviewer can retrace the deduction. Waste factors are stated per material with the word typical where the range varies by trade.
Materials, labor, equipment and cost breakdowns
Every bid item is split into four columns before it is summed:
- Material: quantity times unit cost, with the Producer Price Index movement for that commodity noted where it is volatile.
- Labor: hours times the wage determination rate plus your burden, by classification.
- Equipment: owned or rented, priced by the hour or day with mobilization shown as its own line.
- Subcontractor quote: carried as received, with scope gaps and exclusions listed beside it.
The totals roll up to the bid schedule format in a federal construction cost estimate Excel workbook, with a PDF summary for the review meeting.
Who Needs Our Federal Contractor Estimating?
The audience for a government construction bid estimate is narrow and deadline-driven. Prime contractors assembling an IFB response need subcontractor pricing that matches the schedule of values, and specialty firms need their own scope priced to the same wage determination the prime is using. Both groups lose bids to arithmetic they cannot defend, not to a missing decimal.
A working cost estimator reads the sheet in a specific order: quantities first, then classifications, then burden, then the markup. We structure the workbook in that sequence so a reviewer can stop at any tab and reconcile it to the bid form. That matters when a contracting officer or a bonding underwriter asks how a unit price was derived after award, which is the standard federal contractor estimating has to meet.
Specialty subcontractors bidding federal work
Mechanical, electrical, concrete and site-work subcontractors use the estimate to convert a scope letter into unit prices the prime can plug into the bid schedule. We isolate your divisions, apply the wage determination classifications you will actually payroll, and show the hours behind each line. The trade contractor estimating services page describes how scope gaps against the prime's request are documented.
General contractors and home builders
Primes use the estimate to test subcontractor quotes for completeness and to build the general conditions line that federal schedules rarely itemize. Home builders working on military housing or government-leased residential work get the same treatment at a smaller scale. Our prime contract bid estimating work covers the buyout comparison, and small contractor estimating covers firms bidding their first federal contract.
Developers, architects and suppliers
Owners and designers use an early estimate to test whether a program fits a federal grant or lease budget before drawings are complete. Suppliers and fabricators use the material takeoff to size a quote against the quantities the job will actually consume. For design-side budgeting, see architect and designer cost support; for pro forma work, developer and owner estimating. Federal contractor estimating for these groups stops at a budget range until the solicitation fixes the wage determination.
Types of Federal Contractor Projects We Estimate
Scope changes with project type, and so does the paperwork. A barracks renovation priced under a firm-fixed-price solicitation carries different risk than a design-build hangar where the AACE estimate class is early and the allowances are large. We adjust the measurement detail and the contingency line to match the delivery method, not just the building.
Certified payroll exposure also varies. Projects with heavy overtime, shift work or multiple wage determinations under one contract need the labor lines separated by classification and by period, because the payroll report reconciles week by week. We build that structure into the workbook from the first tab, which is what separates federal contractor estimating from a private-sector takeoff.
Residential projects
Military family housing, dormitories and government-leased apartments are measured room by room with typical-unit multipliers, and finishes are priced per square foot of floor area. Site work and utilities are taken off separately because they often fall under a different wage determination than the building trades. Our home builder estimating services page covers the residential measurement conventions.
Commercial buildings
Administrative buildings, clinics, child development centers and training facilities bring full Division 03 through Division 26 scope plus fire protection and communications. The federal project quantity takeoff here runs to door and hardware schedules, ceiling square footage and fixture counts, each traced to a spec section. The construction cost estimating services page shows the division-by-division structure.
Industrial and infrastructure projects
Hangars, fuel farms, water and wastewater plants, and roadway work bring steel and copper volatility into the estimate, so those lines carry a dated price basis and a stated escalation assumption. Earthwork is measured in cubic yards by cut and fill with shrinkage and swell factors shown. For the underlying quantity work, see quantity takeoff services.
Our Federal Contractor Estimating Process
Every federal contractor estimating job follows the same sequence, and each step produces something you can check. You send the solicitation package — drawing set, specifications, wage determination, and any addendum issued before bid day — and we log what was received against the bid schedule so nothing is priced from a superseded sheet. From there, the takeoff, the labor build-up, and the review all hang off the same drawing index.
Submit drawings and specifications
Send the full drawing set, the project manual with its spec sections, the wage determination attached to the solicitation, and the bid schedule form. If the solicitation carries a general decision that locks Davis-Bacon rates to a specific date, include it — the certified payroll labor rates estimate depends on the classification and rate in force at bid opening, not the rate published later. Tell us your bonding capacity and any bidder-held allowances so the estimate reflects what you can actually carry.
Plan review and digital takeoff
We review the drawings for completeness, flag missing sections or conflicting dimensions, and raise them as RFI items before quantifying. The takeoff is then done on screen, organized to CSI MasterFormat divisions — Division 03 concrete priced by cubic yard with formwork by square foot of contact area, Division 05 metals by ton and by linear foot of member — with each quantity tied to a sheet number and detail. Waste factors are applied per material and stated in the sheet, not buried.
Cost calculation, quality checks and delivery
Labor is built by trade and classification, with fringe benefits and payroll burden shown as separate lines so you can compare them to the wage determination. A second estimator re-adds the extensions, checks unit conversions, and confirms that every bid schedule line has a corresponding takeoff quantity. You receive the Excel workbook, the PDF summary, and marked-up drawing pages; the fee is quoted per project after we review the plans. Start by sending your plans through our construction estimating services page.
Sample Federal Contractor Estimate and Deliverables
The example below is illustrative only: a single-story federal maintenance building of 4,000 square feet, with concrete, structural steel, and electrical scopes taken from a notional drawing set. Rates are placeholders that show the arithmetic, not a quote for your project. A real federal contractor estimating package would also carry the Davis-Bacon general decision number, the performance bond premium, and the GSA schedule construction estimate line structure if the work is ordered off schedule.
| Item | Qty | Unit | Unit cost range | Extended range |
|---|---|---|---|---|
| Division 03 — slab-on-grade concrete, 5 in. | 62 | cubic yards | $185 – $215 | $11,470 – $13,330 |
| Division 03 — slab formwork, perimeter | 320 | square feet | $9.50 – $12.00 | $3,040 – $3,840 |
| Division 05 — structural steel, beams and columns | 18 | tons | $4,200 – $4,900 | $75,600 – $88,200 |
| Division 26 — electrical rough-in, branch conduit and wire | 3,600 | linear feet | $11.00 – $14.50 | $39,600 – $52,200 |
| Division 26 — panelboards and distribution | 4 | each | $2,800 – $3,400 | $11,200 – $13,600 |
| Performance bond premium, illustrative 1.5% of $180,000 base | 1 | lump sum | $2,700 | $2,700 |
| Illustrative total, low to high range | — | — | — | $143,610 – $173,870 |
Excel quantity takeoff sheet
The workbook opens on a takeoff tab organized by CSI MasterFormat division, with columns for sheet reference, description, quantity, unit, and waste factor. Formulas are live, so changing a slab dimension in Division 03 concrete flows through to the concrete and formwork lines. A separate tab holds the bid schedule mapping, so each line on the government form traces back to a takeoff row.
Marked-up drawings
Each drawing page is returned with color-coded highlights and quantity callouts keyed to the workbook row numbers. Structural steel members are tagged with their section size and length; electrical runs are tagged by circuit and linear footage. When an addendum arrives, the marked-up set shows which sheets were superseded and which quantities changed.
Itemized cost estimate
The cost tab separates material, labor, equipment, and subcontractor quote lines, with the performance bond and general conditions shown as their own rows. Labor lines carry the classification, base rate, fringe, and burden, so the figure can be checked against the wage determination without re-deriving it. Every subtotal is formula-linked to the takeoff, and the total is the sum you see, not a typed number.
Software and Pricing Data We Use
Pricing a federal bid schedule means holding material volatility and labor rates in the same model without letting either drift. The chart below tracks the Producer Price Index series for the materials in this scope, rebased to 100, so you can see which inputs moved and by how much over the period shown. The wage table below gives the national median hourly rates we start from before location and prevailing wage adjustments.
Takeoff and estimating software
Takeoffs are done on screen from the PDF drawing set, with quantities exported into a spreadsheet estimating model rather than retyped. Cost databases supply the material and equipment unit costs, and a separate rate table holds labor by trade classification. Keeping the takeoff, the cost database, and the labor table in separate layers is what lets a federal bid schedule pricing revision — say a change order to Division 05 metals tonnage — be re-priced without rebuilding the whole estimate.
Regional material and labor pricing method
We start from national average unit costs, adjust them with published U.S. wage and price data for the project location, then apply the prevailing wage determination attached to the solicitation. Davis-Bacon rates replace the open-shop labor line where the classification applies, and the fringe is carried as its own component. An estimator reviews the finished sheet against the drawing set before it is released, and the assumptions behind every adjustment are written on the page.
Material price movement, Oct 2023 to Sep 2026
| Occupation | 25th percentile | Median | 75th percentile |
|---|---|---|---|
| Construction laborers | $18.57 | $22.66 | $28.72 |
| Carpenters | $23.32 | $29.12 | $36.94 |
| Electricians | $23.76 | $30.38 | $40.36 |
| Plumbers, pipefitters and steamfitters | $24.13 | $30.67 | $40.92 |

Why Contractors Choose Our Estimating Services
The reason to send a federal package out is arithmetic you can audit, not a promise about the answer. Each line on our sheets shows the unit, the measurement rule, the labor classification, and the source of the cost, so a reviewer can re-derive any number in the estimate. That matters most where the government form and the takeoff have to agree line for line.
Trade-specific expertise
Concrete is priced by cubic yard of placement with formwork by contact area, steel by ton with connections and fireproofing broken out, and Division 26 electrical by device, fixture, and linear foot of raceway. The Davis-Bacon fringe benefit calculation is shown as a separate line per classification, so the base rate and the fringe can be compared to the general decision without guesswork. Allowance items are flagged as allowances, not folded into a unit price where they would hide.
Quality control and clear assumptions
A second estimator re-extends every quantity and checks the unit conversions between square feet, cubic yards, and linear feet before the workbook is released. Assumptions — waste factors, haul distances, shift premiums, temporary power — are written on the summary page rather than left in the formulas. Where a drawing is silent, the sheet says so and prices the item as an open question for the RFQ response.
Turnaround, communication and revisions
Delivery dates are agreed when we quote the project, based on the size of the drawing set and the number of trades involved, and we confirm the date in writing before starting. Revisions from an addendum or a changed bid schedule are handled as a re-price of the affected rows, with the changed quantities marked so you can see what moved. Questions during review go to the estimator who built the sheet, not a shared inbox. See the bidder types we support page for how this fits different bidders, or get a quote once your solicitation package is ready.
Federal Contractor Estimating Pricing
The fee for federal contractor estimating is quoted per project after we review the solicitation and the drawing set. There is no published rate card, because an IFB with 40 sheets across six divisions and a two-line RFQ for a guard booth do not carry the same work. Send the plans and the bid schedule through request a quote and we price the scope we can actually measure.
Every figure in the workbook traces to a unit, a measurement rule and a public data source. That matters most on a federal construction cost estimate excel file that a contracting officer or a reviewing estimator may open line by line.
How quotes are calculated
We count the sheets, list the CSI MasterFormat divisions present, and read each spec section for the units the government expects — cubic yards in Division 03 concrete, tons in Division 05 metals, linear feet in Division 26 electrical raceways. The quote follows that scope: number of trades, number of alternates and unit-price items in the bid schedule, and whether addenda changed the drawings after issue.
A lump sum bid schedule with five alternates and two allowance items takes more sheet time than a single lump sum, and the quote reflects it. We do not quote from a square-foot rule of thumb; we quote from the measured scope.
What affects price and delivery time
Sheet count and trade count drive most of the effort, followed by addenda — each one forces a recheck of the quantities it touches. A bid date that moves up compresses review time, and a solicitation with a detailed unit-price schedule adds line items we must carry separately rather than roll into a lump sum.
We confirm the delivery date with the quote, in writing, against your bid day. The calculator below is for your own early budgeting: enter building area, your base hard cost per square foot, and your soft-cost, contingency and escalation percentages, and it returns hard cost, soft costs, contingency, escalation, budget total and all-in cost per square foot. It holds no prices of its own and no building-type presets — the base cost is yours.
A waste factor belongs in the base hard cost you enter, not in the calculator. If you carry 5% waste on Division 03 concrete and 10% on Division 09 finishes, put the blended number into your square-foot figure before you run it. The bid estimating services page covers how we handle alternates and unit-price schedules on bid day.

Federal Contractor Estimating Across the US
Prevailing wage is the regional variable that moves a federal bid most. A wage determination issued for a county sets the general decision rates and fringe benefits that go on the certified payroll, and those rates differ from one locality to the next even for the same trade. Our labor lines carry the applicable determination rather than a national average, so a Davis-Bacon wage takeoff in one state does not get reused in another.
Material delivery and climate shift the rest. Steel and copper wire pricing has moved sharply over the past year per the Producer Price Index, and freight to a remote site adds to every delivered unit. Cold-weather regions extend concrete curing and earthwork seasons; hot regions change roofing and coating schedules. Confirm the local code edition with the building department before you price to it.
We serve all U.S. states from one team, so sam registered contractor estimating follows the same method everywhere: a federal project quantity takeoff built from the drawing set, with linear feet, square feet and cubic yards measured to a stated rule. Review the client types we estimate for page to see how that carries across project types.
Frequently Asked Questions
How much does a federal contractor estimate cost?
The fee is quoted per project after we review the plans, because scope drives the work: a single-building renovation with a short bid schedule prices differently from a multi-site IDIQ package with dozens of wage determinations. Volume of drawing sheets, number of spec sections, and how many trades need separate labor rate build-ups all move the fee. Send the solicitation and drawings and we return a written quote.
How long does a federal contractor takeoff take?
We do not publish a fixed turnaround. The delivery date is set when we quote, based on sheet count, the number of CSI MasterFormat divisions in scope, and how many wage determinations apply. Federal packages usually need the full solicitation reviewed first, since amendments and addenda change quantities. The date is confirmed in writing with the quote, and we work to your bid day.
Do you estimate labor and material costs?
Yes. Material quantities come from the drawing set by division, and labor is built from the applicable Davis-Bacon wage determination: base rate, fringe credit, and your burden. We separate material, labor, and equipment so each line can be checked. Prevailing wage rates are applied by classification and county, not averaged across the project. See our labor cost estimating services for how the rate build-up works.
What drawings do you need?
Send the complete solicitation: IFB or RFQ, drawings, specifications, wage determinations, and every addendum issued to date. Bid schedules and unit price sheets are needed too, because the estimate must populate your schedule, not a generic summary. If drawings are issued in packages, send all of them; a partial set produces quantities that cannot be reconciled at bid day.
Can you use my estimate template?
Send your template with the plans and we confirm whether the estimate can be delivered in it. Excel workbooks with a defined bid schedule, unit price columns, and division subtotals are usually workable. If your template carries locked formulas or a structure that conflicts with the takeoff, we say so before the quote rather than after delivery.
Do you sign NDAs?
Clients can request an NDA before sending drawings, and the terms are agreed before plan review starts. Send the document you want signed with your initial inquiry so the review and the paperwork happen in the same step. We do not describe a standard NDA policy; each request is handled as submitted.
How do you handle Davis-Bacon fringe benefits in the estimate?
Each classification is priced from its general decision: the base hourly rate plus the fringe rate, with your actual fringe contribution credited against the required total. If your bona fide plan pays less than the determination requires, the difference is added as cash. Labor burden for insurance, taxes, and overhead is applied separately so the certified payroll rate stays visible.
Can you price a bid schedule with unit prices and lump sums?
Yes. Unit price items are priced from measured quantities with the unit stated, such as cubic yards for Division 03 concrete or linear feet for Division 26 conduit, and lump sum items are backed by a quantity build-up rather than a single number. Additive and deductive alternates are carried as separate columns so the base bid stays clean.
How do you treat allowances and change order pricing in a federal bid?
Allowances are shown as a stated dollar amount with the scope they cover, and they are excluded from the measured subtotal so the two do not double-count. For change order pricing, we can build unit rates you can apply later, which matters on federal work where modifications are negotiated against the contract's rate schedule.
Do you estimate projects that require bonding capacity review?
We produce the cost side that bonding and surety review depends on: a division-by-division subtotal, a clear material and labor split, and a documented basis for each major line. Performance and payment bond premiums are carried as a separate line so the underwriter sees them apart from construction cost.
Which CSI divisions do you cover on a federal quantity takeoff?
All 50 divisions in the current MasterFormat format, 00 through 49, from Division 03 concrete through Division 26 electrical and Division 05 metals. Divisions are taken off separately and reconciled to the spec sections, so a line in the bid schedule traces back to the drawing sheet and specification article it came from.
How do you keep quantities traceable when an addendum changes the drawings?
Every quantity carries its sheet reference and measurement rule, so when an addendum revises a plan we re-measure only the affected areas and mark the change. The workbook shows the revision, and the PDF summary flags which bid schedule lines moved. That record is what you use if a quantity is questioned after award.
What makes federal contractor estimating different from a private commercial bid?
Federal contractor estimating starts with the wage determination, not the drawings. Every labor line must map to a classification in the general decision for that county, and the bid schedule dictates the format of the answer. Material pricing follows the same public producer price index data as private work, but labor cannot be priced from a market average.
Can you estimate a GSA schedule construction estimate or task order pricing?
We can build the cost basis for GSA schedule pricing and task order proposals: labor rates by classification, material quantities by division, and a subtotal structure that matches the proposal format you submit. The rates you file on the schedule remain your commercial decision; we supply the measured cost behind them.
