What does a general contractor estimating service deliver?
General contractor estimating services deliver a quantity takeoff and priced cost breakdown built from your drawings and specifications, organized by CSI MasterFormat division. KNR returns an Excel workbook, a PDF summary and marked-up drawing pages showing each line item's unit of measure, quantity rule and pricing basis.
Our Professional General Contractor Estimating
A general contractor's estimate has to survive bid leveling, a scope review with the owner and the first change order. Our general contractor estimating services build the number from the drawings up: each line item carries a unit of measure, a measurement rule, the arithmetic and a public data source for the wage or material price behind it. You receive an Excel workbook, a PDF summary and marked-up drawing pages that show where every quantity came from.
We assign each estimate an AACE estimate class before we start, because a Class 4 budget from a schematic set and a Class 2 bid estimate from a full set of construction documents are priced to different tolerances. Every general contractor estimate is reviewed by an estimator who checks the quantities against the plan sheets and specification sections before the workbook is released.
Material quantities by division
We measure materials from the plan sheets by CSI MasterFormat division, using the unit each trade buys in: square feet of wall area, linear feet of pipe, cubic yards of concrete, board feet of lumber and tons of structural steel. Waste factors are applied per material and labeled as typical, so you can see the 10% added to a flooring order separately from the 5% added to a framing package. The deliverable is a material takeoff you can send straight to suppliers for pricing, with the measurement rule noted on each line.
Crew hours and loaded wage rates
Crew hours are built from production rates and converted to dollars with a labor rate that shows the base wage, payroll burden and trade-specific add-ons as separate columns. Wage inputs come from public U.S. Bureau of Labor Statistics data by trade and are adjusted for your market, so a carpenter's hour and an electrician's hour are never blended into one average. Supervisory time for first-line construction supervisors is carried in general conditions rather than buried in the trade lines.
Bid-ready pricing with alternates
The bid-ready package organizes the estimate by division and by bid package, so each subcontractor quote can be dropped against the line items it covers and checked for scope gaps. Alternates and allowances sit on their own lines with unit prices, and the summary separates direct cost, general conditions, overhead and profit. General contractor estimating ends with a number you can defend line by line, and for a walkthrough of how the bid number is assembled, see how to estimate construction projects as a general contractor.
What Is Included in Our General Contractor Estimates?
Construction cost estimating for general contractors covers the whole building, which means the workbook has to hold Division 01 general requirements alongside concrete, metals, finishes and mechanical trades without losing the thread between them. We structure every estimate on the current 50-division CSI MasterFormat so your project manager, your superintendent and your subcontractors read the same line numbers. General contractor estimating also has to survive bid leveling, so each line carries enough detail to compare a subcontractor quote against the measured scope.
Each section below explains what lands in the workbook and how it is checked.
Division 01 through 49 scope coverage
The estimate opens with Division 01 general requirements: supervision, temporary facilities, submittals, closeout and the schedule-driven items that carry the job. From there, every scope division is measured from the drawings and cross-checked against the specification sections, including addenda issued during the bid period. Items the documents leave open are listed as requests for information rather than priced on assumption, and each one is flagged in the bid estimate summary so you know what is still unpriced.
Quantities, units and measurement rules
Each quantity takeoff line records the plan sheet reference, the unit of measure and the measurement rule applied, so a reviewer can re-measure any line in minutes. Openings are deducted from wall areas, concrete is measured to the neat dimension with formwork in square feet of contact area, and rebar is converted to tonnage. A contingency line is carried at a stated percentage tied to the AACE estimate class, not folded silently into unit costs.
Materials, labor, equipment and cost breakdowns
The cost breakdown structure splits every line into its parts, which lets you test the number instead of accepting it:
- Material — quantity times unit price, with the source of the price noted.
- Labor — crew hours times a labor rate, with burden shown separately from base wage.
- Equipment — rental or ownership cost by duration, including cranes, pumps, lifts and compaction gear.
- Subcontract — quoted scope mapped to the division lines it covers.
- General conditions, overhead and profit — carried as their own summary rows.
The workbook is delivered as a general contractor estimating Excel file with a PDF summary and marked-up drawings, so the arithmetic can be audited line by line. If you want the measurement side handled separately, our quantity takeoff services produce the same traceable quantities.
Who Needs Our General Contractor Estimating?
Three groups use a general building contractor takeoff, and each one reads a different part of the workbook. Subcontractors check the quantities against their own scope before quoting; general contractors use the numbers to assemble and level the bid package; owners and designers use the cost breakdown to test a budget before drawings are complete. The link list on our who we serve page maps each group to the right service line.
A material takeoff is only useful if the reader can find the line they doubt, so every deliverable keeps sheet references and measurement rules visible. That traceability is what separates general contractor estimating from a lump-sum guess, and it is the reason a reviewer can audit any line without calling us.
Specialty subcontractors
Trade contractors use the division-level quantities to price their portion of the bid package without re-measuring the whole set. A framing or drywall subcontractor can pull the wall areas and opening deductions, add their own labor rate, and return a quote that lines up with the general contractor's sheet. Our subcontractor estimating services cover single-trade takeoffs when you only need your own scope.
General contractors and home builders
General contractors use the workbook to build the bid, compare subcontractor quotes and spot scope gaps before submission. Home builders working from residential sets get the same treatment at a smaller scale, with general conditions and overhead and profit shown separately. See home builder estimating services for the residential format.
Developers, architects and suppliers
Developers test pro formas against a cost breakdown by division, architects check that the design intent is priced, and suppliers use the material quantities to prepare quotes. Each group gets the same traceable lines, filtered to what they need. Our developer and owner estimating page explains the budget-stage format, and the same general contractor estimating workbook can be reissued when an addendum changes the scope.
Types of General Contractor Projects We Estimate
Scope changes with the building type, and so does the estimate. A residential set turns on finishes and framing quantities, a commercial building turns on Division 01 requirements and long-lead equipment, and an industrial job turns on process scope and heavy structural steel. In all three, gc bid estimate preparation depends on reading every plan sheet and specification section, including the addenda.
We keep CSI MasterFormat divisions consistent across project types so a developer comparing two buildings sees the same structure. Overhead and profit are carried as summary rows, never distributed into trade unit prices. That consistency is the point of general contractor estimating: a reviewer can trace any line back to its division, unit of measure and measurement rule.
Residential projects
Single-family and multifamily estimates are measured from floor plans and elevations, with framing lumber in board feet, drywall in square feet and concrete in cubic yards. Residential work carries fewer Division 01 requirements but more finish allowances, so selections that are not yet made appear as labeled allowances. Our small contractor estimating page covers the builder-scale format.
Commercial buildings
Office, retail, hospitality and institutional work brings full Division 01 scope, fire protection, elevators and mechanical systems that need subcontractor quote comparison. The bid package is organized so each trade quote maps to the lines it covers, and alternates are priced separately. Start with our commercial construction estimate page for the building-type breakdown.
Industrial and infrastructure projects
Warehouses, plants and site-heavy work shift the estimate toward structural steel, concrete, process piping and site utilities, where material price movement matters most. Public Producer Price Index series for steel, lumber, ready-mix and copper wire show how far those inputs have moved over the past year, and we apply the relevant change to the material lines. Send your plans through request a quote and we will confirm scope and fee after reviewing the set.
Our General Contractor Estimating Process
Every estimate starts with the same three steps, and each step ends with a check that the next one depends on. The output is a line-item estimate you can carry into a bid, with the arithmetic visible on every row.
We work from the full bid set: architectural, structural, civil, MEP and the Division 01 general requirements that set temporary facilities, submittals, closeout and schedule obligations. Send the drawings, the specification sections and every addendum issued to date through send your plans; a set missing an addendum is the most common reason a takeoff has to be redone.
Submit drawings and specifications
Send the complete set as PDFs, with a sheet index and the specification sections that govern materials and installation. Note the bid date, the alternates and allowances you are carrying, and any subcontractor quote you have already received. We log the set, confirm the addenda list and flag missing sheets before any measuring begins.
Plan review and digital takeoff
An estimator reviews the sheets for scope, then performs a quantity takeoff for general contractors on screen, measuring each assembly against a stated rule. Concrete is measured by cubic yard to the neat dimensions, formwork by square foot of contact area, and finishes by square foot of actual surface. Every measured quantity carries its sheet reference so you can trace it back to the drawing.
Cost calculation, quality checks and delivery
Quantities are priced with labor, material and equipment separated, then a second estimator reviews the sheet for missing scope and arithmetic errors. The review checks that each specification section in the set has a matching line item and that no subcontractor quote was double-counted. You receive an Excel workbook and a PDF summary with marked-up drawings; the fee is quoted per project after we review the plans.
Sample General Contractor Estimate and Deliverables
The example below is illustrative only: a single-story 4,000 square foot tenant fit-out shell package priced at national average rates. It shows how a general contractor cost breakdown is built, with the unit of measure and the measurement rule printed on each row so the quantity can be rechecked against the plan sheet.
The arithmetic: 240 cubic yards of slab-on-grade concrete at $185 to $215 per cubic yard extends to $44,400 to $51,600; 4,000 square feet of drywall at $2.10 to $2.60 per square foot extends to $8,400 to $10,400. The five trade rows total $85,930 at the low end and $101,580 at the high end; adding general conditions at 8% brings the package to $92,804.40 to $109,706.40. A scope gap appears when a specification section in the set has no matching row, and an addendum issued after the takeoff is logged as a revision rather than folded silently into the total.
| Item | Qty | Unit | Unit cost range | Extended range |
|---|---|---|---|---|
| Slab-on-grade concrete, 5 in. | 240 | cubic yard | $185 – $215 | $44,400 – $51,600 |
| Interior metal stud partitions | 1,850 | square foot | $9.50 – $11.00 | $17,575 – $20,350 |
| Gypsum board, tape and finish | 4,000 | square foot | $2.10 – $2.60 | $8,400 – $10,400 |
| Suspended acoustic ceiling | 2,400 | square foot | $3.80 – $4.60 | $9,120 – $11,040 |
| Painting, walls and ceilings | 5,850 | square foot | $1.10 – $1.40 | $6,435 – $8,190 |
| General conditions, 8% of trade total | — | lump sum | — | $6,874.40 – $8,126.40 |
| Total | — | — | — | $92,804.40 – $109,706.40 |
Excel quantity takeoff sheet
One row per line item, with the description, quantity, unit of measure, measurement rule, plan sheet reference and cost code. Formulas stay live so you can change a waste factor or a labor rate and see the extended cost update.
Marked-up drawings
The same quantities highlighted on the plan pages, color-coded by trade, so a reviewer can confirm a wall length or a slab area in seconds. Markups carry the same row numbers as the workbook.
Itemized cost estimate
Labor, material and equipment split per line, with general conditions, overhead and profit carried as separate rows rather than buried in unit prices. The PDF summary mirrors the workbook totals and lists the assumptions and exclusions in plain language.
Software and Pricing Data We Use
Pricing is only as good as the inputs behind it, so we separate the measured quantity from the rate applied to it. The chart below tracks the Producer Price Index series for the materials in this scope, rebased to 100, and the wage table below shows the national median hourly rates we start from. Material indexes move independently: lumber, ready-mix, steel and copper wire each follow their own curve, which is why a single escalation percentage applied to a whole estimate distorts the trades that use different materials.
A masterformat estimate for gc work follows the current 50-division format, 00 through 49, so the cost codes line up with how your accounting and schedule of values are organized.
Takeoff and estimating software
We use three tool categories: PDF and on-screen takeoff for measuring from the plan sheets, spreadsheet estimating for the line-item build and formulas, and commercial cost databases for unit price starting points. Each measured quantity is tied to a sheet and a measurement rule, so a reviewer can reproduce it without asking us how a number was reached.
Regional material and labor pricing method
We start with national average unit costs, apply the BLS wage data and Producer Price Index movement shown in the chart and the wage table below, then adjust for location, prevailing wage requirements and project conditions. An estimator reviews the result before release. The waste factor is set per material and stated on the row, so a 10% allowance on tile is visible rather than hidden. Bid leveling notes and any request for information raised during review are attached to the workbook.
Material price movement, Oct 2023 to Sep 2026

Why Contractors Choose Our Estimating Services
The reason is method, not marketing: every number on the sheet can be traced to a drawing, a measurement rule and a published data source. That matters most when a bid package quantity takeoff is challenged by an owner's reviewer or when a losing bid turns on a scope item nobody priced.
We also carry alternates and allowances as separate line items, so a base bid, an alternate and an owner allowance never blur into one total. The same structure feeds a schedule of values after award.
Trade-specific expertise
Concrete, structural steel, MEP and finishes are measured and priced by estimators who work in those divisions, each with its own unit of measure and measurement rule. A mechanical estimator measures pipe by linear foot and fittings by count; a concrete estimator measures formwork by contact area. The divisions are then rolled into one estimate so the general conditions and overhead lines are applied once, not per trade.
Quality control and clear assumptions
A second estimator reviews every sheet against the specification sections, checking that each section has a matching row and that no quantity is counted twice. Assumptions, exclusions and open questions are written on the sheet, not left in an email. If a drawing is ambiguous, we raise a request for information rather than guess.
Turnaround, communication and revisions
Delivery dates are agreed when we accept the project, based on the set size and the bid date you give us. Revisions from an addendum or a revised sheet are logged against the original rows so you can see what changed. Questions during the estimate go to one estimator who owns the sheet, and you can review the scope with professional construction estimating services before the bid goes out.
General Contractor Estimating Pricing
Our fee is quoted per project after we review the plan set, so there is no published rate card. What drives the number is the volume of sheets to measure, the number of CSI MasterFormat divisions in scope, how many alternates and allowances the bid form requires, and whether the documents are at a full construction-issue level or still carrying addenda and open RFIs. A two-story tenant improvement with Divisions 03 through 33 priced against a clean set is a different job from a phased renovation where the structural drawings are half-issued.
A general contractor estimating excel deliverable is priced by the work behind each line item, not by row count. We measure every assembly against a stated measurement rule, apply a waste factor where the material warrants one, and carry an allowance only where the drawings genuinely cannot fix a quantity. Send your plans and we will confirm scope and quote a fixed fee before any takeoff begins.
How quotes are calculated
We review the drawings and specifications first, then scope the fee to the divisions you actually need priced. The quote reflects sheet count, trade count, the number of bid packages you intend to let, and the level of detail your bid form demands — a summary-level estimate is priced differently from a full quantity takeoff with a line for every fitting and hanger. The calculator below converts your own assumptions into a budget; it does not set our fee, which stays project-specific.
What affects price and delivery time
Addenda issued after our start, incomplete architectural finish schedules, and alternates that must be priced separately all add work. So does a set with no structural or MEP drawings, because we then have to price from narrative and note the assumptions. We do not state a turnaround until we have seen the documents, and we will tell you plainly if the date you need is achievable.

General Contractor Estimating Across the US
Wage levels set the labor half of every unit price, and they move by region. A carpenter hour in a high-cost metro and the same hour in a rural county are different numbers, so we build labor from published U.S. Bureau of Labor Statistics wage data for the project's location and add the burden your trade contracts carry. On public work, prevailing wage determinations replace the market rate and can shift the labor line substantially.
Material delivery and climate change the rest. Ready-mix, structural steel and copper wire pricing varies with distance to the nearest plant or mill, and a cold-climate schedule adds winter protection and temporary heat that a southern project never carries. Code editions differ too: we price to the IBC or IRC edition your building department enforces, and you should confirm that edition before bid. One team handles every state, and a construction estimate review for gc clients runs against the same cost breakdown structure regardless of location, with each linear foot, square foot and cubic yard traceable to its measurement rule.
Frequently Asked Questions
How much does a general contractor estimate cost?
The fee is quoted per project after we review the plans, so it depends on sheet count, the number of CSI MasterFormat divisions in scope, whether you need alternates and allowances priced separately, and how complete the specifications are. Send the drawing set and bid date and we return a written quote that states the fee and the deliverable before any takeoff work begins.
How long does a general contractor takeoff take?
The delivery date is set when we quote, based on the scope we can see in the drawings and the divisions you need priced. Large bid packages with many specification sections and pending addenda take longer than a single-building shell. We confirm the date in writing with the fee, and we flag any addendum that arrives after the takeoff starts.
Do you estimate labor and material costs?
Yes. Each line item carries a quantity with its unit of measure, a material unit cost, and a labor unit cost built from a published wage rate plus burden, so you can see how the number was assembled. Material pricing is adjusted with published producer price data by commodity group, then reviewed by an estimator before it goes into the workbook.
What drawings do you need?
Send the full architectural, structural, and MEP plan sheets, the specification book, the geotechnical report if you have it, and every addendum issued to date. A site plan and the finish schedule help with Division 01 general requirements and general conditions. If a sheet is missing we issue a request for information rather than guess at the scope.
Can you use my estimate template?
Send your template with the plans and we confirm whether the estimate can be delivered in it. We can map our cost breakdown structure to your division and subdivision codes, your schedule of values format, and your unit price columns. If a template field cannot be populated from the drawings, we say so before the takeoff starts.
Do you sign NDAs?
Clients can request an NDA before sending drawings, and the terms are agreed before plan review begins. Send the document with your first message so it is executed ahead of the file transfer. We do not publish a standard NDA policy, so the agreement is handled case by case.
What is general contractor estimating?
General contractor estimating is the assembly of a complete bid from every trade package, priced in CSI MasterFormat divisions and reconciled against subcontractor quotes. It covers material quantity takeoffs, labor hours with burden, general conditions, overhead and profit, alternates, and allowances. The output is a cost breakdown you can defend line by line at bid leveling.
How do you handle subcontractor quotes in the bid?
We enter each quote against the scope it covers and mark the divisions where no quote was received. During bid leveling we compare quote inclusions against the specification section so scope gaps surface before you sign. Anything the quote excludes stays visible in the workbook rather than being absorbed into a lump sum.
What estimate class do you deliver?
Most bid-stage work falls in AACE Class 2 or Class 3, depending on how far the design documents have progressed. We state the class and the contingency basis on the summary page so you know how much of the number is measured quantity and how much is allowance for undefined scope. Schematic sets are priced with wider contingency than permit sets.
How do you price general conditions and Division 01?
General conditions are built from the project schedule: supervision hours, temporary facilities, permits, cleanup, and closeout, each as its own line. Division 01 general requirements are taken from the specification section by section, including submittals, testing, and commissioning. Both are separated from trade work so you can adjust them without disturbing the takeoff.
Can you break the estimate down by building or phase?
Yes. We structure the workbook so quantities roll up by building, floor, or phase, which lets you release bid packages separately and track a schedule of values against the same line items. Tell us the phasing plan with the drawings and we set the cost breakdown structure to match it.
How do you treat waste factors and measurement rules?
Each material line states the measurement rule used and the waste factor applied, so a reviewer can retrace the quantity from the plan sheet. Typical waste allowances are applied for cutting and breakage on finishes, lumber, and sheet goods, and the percentage is shown as a column rather than buried in the unit price.
Do you mark up the drawings?
Yes. The deliverable includes marked-up drawing pages showing where each quantity was measured, alongside an Excel workbook and a PDF summary. A reviewer can open the marked sheet, find the highlighted area, and check the arithmetic against the line item without re-measuring the whole plan.
Can you review an estimate we already prepared?
We can run a construction estimate review against your workbook, checking quantities against the plan sheets, verifying unit costs against current published wage and price data, and listing scope gaps by division. The output is a written exception list you can act on before the bid is submitted.
