What do construction estimating services include?

Construction estimating services convert plan sheets and specification sections into measured quantities, priced line items and a bid total. KNR delivers an Excel workbook, a PDF summary and marked-up drawings, with each quantity showing its unit of measure and measurement rule and each price traceable to public wage and price data.

What Our Construction Estimating Services Cover

Our construction estimating services are organized around the document you are holding and the decision you have to make with it. A plan and spec takeoff answers "how much of each item is on these sheets"; cost estimating answers "what will that quantity cost in this market"; bid work answers "what number goes on the bid form at 2:00 p.m." Each output is built the same way: a unit of measure, a measurement rule, the arithmetic, and the source behind every rate.

Takeoffs are counted, not guessed. Linear feet for pipe, conduit, curbs and flashing; square feet for formwork, drywall, roofing and flooring; cubic yards for concrete and excavation; count each for fixtures, doors, hangers and devices. Every line carries its CSI MasterFormat division, so a takeoff for Division 03 concrete and Division 26 electrical lands in the same workbook format your estimator and your subcontractors already read.

We read the full document set before counting: plan sheets, the specification section for each assembly, the geotechnical report where it affects excavation, and every addendum issued before the bid date. An addendum that moves a wall or changes a door schedule is applied to the quantities and flagged in the summary, so you can see what changed between revisions. Fees are quoted per project after we review the plans; the deliverable is an Excel workbook and PDF summary with marked-up drawing pages.

The group splits by purpose rather than by trade. Use measured quantity takeoffs when you need quantities only, priced cost estimating when those quantities need unit costs, labor and markup, and bid estimate preparation when a bid date is fixed. Early in design, conceptual and schematic design estimating gives a range from program areas before drawings are complete.

Which Service Fits Your Project

Pick the service by the question you need answered, not by the size of the project. A trade contractor estimating a Division 05 steel package and a general contractor pricing a full building both start with a material takeoff; they diverge at labor, equipment and markup. The AACE estimate class tells you how much contingency the number needs, and the square feet per unit ratios in a conceptual model are only as good as the program areas you supply.

If you are comparing a construction estimating company against doing it in-house, count the hours first: a full plan and spec takeoff on a mid-size building runs into hundreds of sheets, and the cost estimator's time is the line item that moves. Our construction estimating services are organized so you can start from a construction estimate built on measured quantities rather than allowances, or from a construction cost estimate priced line by line. The table below maps each service to the situation it fits and the deliverable you receive.

Matching the Estimate to the Design Stage

Construction estimating services follow the drawing set, and the drawing set follows a sequence. At concept, you have program areas and a building type; the estimate is a conceptual estimate built from square feet or beds or keys, with a wide range and an AACE Class 5 label. At schematic design, wall types and structural system are set, so quantities can be taken by assembly and priced with published unit costs. At design development, the specification sections firm up and the takeoff moves to CSI MasterFormat divisions, with concrete measured in cubic yards and metals in tons and linear feet.

At construction documents, the set is bid-ready: every Division 03 through Division 33 scope can be counted, alternates separated, and the estimate checked against the bid form. At bid, the number is fixed and the work becomes change control. Moving a number from Class 5 to Class 1 is not a matter of confidence; it is a matter of how much of the scope is drawn, specified and measured.

The calculator below takes your base estimate and the AACE estimate class you are working at, from 5 to 1, and returns a low and high contingency with the resulting budget range. Use it to see how much of your budget is allowance rather than measured scope, and carry that range into budget estimating built for funding requests before the number reaches a funding request.

Contingency range by estimate class

Low contingency
$150,000 (10%)
High contingency
$300,000 (20%)
Budget range
$1,650,000 – $1,800,000

Typical planning ranges that follow the AACE estimate-class idea: less design, more contingency. Set the final figure from a risk review of your own project.

How We Deliver Construction Estimating Services

Every service in this group runs through the same five steps, so a client who starts with a schematic design estimate can carry the same sheet through to a bid package without rebuilding it. What changes between services is the input drawings, the level of detail, and how the numbers are summarized. Our plan and spec takeoff work is the measuring half of the job; pricing, review and formatting are the half that turns measurements into a document you can send out.

The process is built so that every quantity on the sheet can be traced back to a plan sheet or a specification section. When a reviewer asks why Division 03 concrete shows a particular volume, the answer is a dimension, a rule and an arithmetic line, not an opinion.

  1. Intake and scope check

    We start by logging the drawing set: sheet count, revision dates, specification sections and any addenda issued before the estimate date. Missing sheets and superseded addenda are the most common cause of a wrong bid, so anything absent is listed and confirmed with you before measuring begins. The scope of work is then split by CSI MasterFormat division so that each trade can be priced and checked separately.

  2. Takeoff

    Each line item is measured in its own unit: square feet for formwork and drywall, cubic yards for concrete, linear feet for pipe and conduit, and count each for fixtures, doors and equipment. Division 03 concrete is a useful example, because the same pour produces formwork area, concrete volume, reinforcement weight and finish area, each with its own unit. Every dimension is read from a named plan sheet, and the measurement rule is written beside the quantity.

  3. Pricing

    Quantities are priced with unit costs built from material, labor hours at a productivity rate, and equipment where the method requires it. Sales tax and freight are added where the material is taxable or delivered, and markup and contingency are shown as separate lines rather than buried in the unit rate. A schematic design estimate at this stage carries wider allowances than a construction documents estimate, and the sheet states which basis was used.

  4. Review

    A second estimator checks the takeoff against the drawing set before anything is released, looking for missed sheets, double-counted areas and unit errors. Review also tests the arithmetic: extended quantities, subtotals by division and the summary roll-up are recalculated. Discrepancies are corrected on the sheet and noted, so you can see what changed and why.

  5. Delivery

    You receive an Excel workbook, a PDF summary and marked-up drawing pages showing where each quantity was measured. The workbook keeps quantities, unit costs and extensions in separate columns so your team can adjust a rate without breaking the totals. Alternates are carried as separate line items, so a base bid and its options can be compared without re-measuring.

Cost Data Behind Our Pricing

Material pricing does not sit still between the day a takeoff is measured and the day a bid is submitted, so the material takeoff services we provide are priced against published producer price data rather than a static catalog. The chart below tracks the Producer Price Index series for the materials in this scope, rebased to 100 so that lumber, ready-mix concrete, steel mill products and copper wire and cable can be compared on one axis. A rising line means the material component of a unit cost is under pressure; a flat line means the rate is likely to hold.

For Division 05 metals, that distinction matters most on structural steel and miscellaneous items, which move with mill pricing rather than with local labor. A bid package priced from construction documents three months before the bid date should note which index month the material rates reflect, so the reviewer knows what has changed since. Our construction cost estimating services apply the same index logic to every division on the sheet, and each construction takeoff records the index month its material rates were drawn from.

Trade Wages We Start From

Labor in an estimate is built in two layers. The base wage is the hourly rate for the trade; the loaded rate adds payroll taxes, insurance and fringe to reach the cost a contractor actually carries. The wage table below shows national hourly wages by trade at the 25th percentile, median and 75th percentile, which lets us place a crew at the right point in the market rather than at a single national average.

For bid estimate preparation, the loaded rate and the crew hours are what drive the labor line, and both are written on the sheet. Division 26 electrical work is a good illustration: an electrician's base wage is only part of the cost, because the crew hours depend on the productivity rate for the specific installation, and the scope of work determines how many of those installations there are. A general contractor reviewing the estimate can see the wage, the burden, the hours and the extension as separate columns.

Where Estimates in This Group Go Wrong

Most failures in this group trace to one line item that was measured on the wrong basis or priced from the wrong source. The check is always the same: pull the plan sheet, point to the dimension, and confirm the unit of measure matches the pricing table. An estimator who cannot reproduce the number from the drawing in under a minute has not finished the takeoff.

A second recurring error is scope that crossed between packages. When a trade contractor's bid excludes firestopping at Division 05 penetrations or the concrete pump in Division 03, the gap surfaces at buyout, not at bid. We reconcile each subcontractor bid against the specification section list before the number leaves the sheet.

Failure modeWhat it looks like on the sheetCheck that catches it
Wrong unit basisConcrete priced by square feet of slab instead of cubic yardsRecompute from thickness and area; cubic yards = area × depth ÷ 27
Count missedDoors taken off by leaf count, frames and hardware omittedCount each opening, then add frame and hardware lines per opening
Stale pricingLumber carried at last year's mill priceRe-price against current producer price data before release
Double-counted wasteWaste factor applied to both material and installed costApply waste to material quantity only, never to labor hours
Scope gapDivision 26 feeders shown but not pricedWalk the specification section index against the takeoff lines
Labor assumed, not builtCrew hours entered as a lump sumRebuild from productivity rate × quantity ÷ crew size

Construction cost estimating fails quietly when a number is plausible but unreproducible. Our sheets carry the dimension reference beside every quantity so the check is mechanical rather than a matter of trust.

Request Construction Estimating Services

Send the plan sheets and the specification sections as a single set, plus any addenda issued after the bid date and the bid form if you have one. For outsourced estimating services we also need the scope splits you intend to carry: which Division 03, 05 and 26 work stays in-house and which goes out. A waste factor you already use on your own jobs should come with the package so our quantities match your history.

We review the set, confirm the drawing index against the specification section list, and quote a fee per project. The deliverable is an Excel workbook and PDF summary with marked-up drawing pages, so each line traces back to a sheet. Where a subcontractor bid arrives later, we can check it against our takeoff before you sign. Start with our professional digital plan takeoff services or send drawings through the estimate request page.

Frequently Asked Questions

What is included in your construction estimating services?

Our construction estimating services produce a line-item estimate tied to CSI MasterFormat divisions, with quantities, units of measure, waste factors, labor hours at a stated crew productivity rate, material pricing, sales tax, freight, markup and contingency shown separately. You receive an Excel workbook, a PDF summary and marked-up drawing pages, so any line can be traced back to the plan sheet, specification section or addendum it came from.

How is your estimating fee set?

The fee is quoted per project after we review the plans, because scope, sheet count and the number of trades drive the effort. A single-division package prices differently from a full building with alternates. Send the drawing set, specifications and any addenda, and the quote states the fee and the delivery date together so you can compare it to the bid deadline before committing.

How long does an estimate take?

The delivery date is set when we quote, based on the drawing set you send, the divisions in scope and the bid date you are working toward. We confirm that date in writing with the fee before plan review starts. Send the complete set with addenda rather than partial sheets, since missing pages are the most common reason a date has to be renegotiated.

Can you work from a partial drawing set or a design narrative?

Yes, provided the estimate is labeled for what it is. A schematic design set supports a Class 3 or Class 4 AACE estimate with allowances and a stated contingency; construction documents support a Class 2 or Class 1 bid estimate. We note the basis of each allowance in the workbook so you can see which lines will firm up as drawings develop.

Do you sign NDAs?

Clients can request a non-disclosure agreement before sending drawings, and the terms are agreed before plan review begins. Send the request with your first message so the paperwork is settled ahead of the file transfer. We do not publish a standard NDA policy, so the terms are confirmed case by case with you.

Can you use my estimate template?

Send the template with the plans and we confirm whether the estimate can be delivered in it. Most workbooks with a defined division structure, unit column and quantity column can be populated directly. Where your template carries formulas or cost codes we cannot reproduce, we deliver our workbook and map our line items to your structure.

How do you handle alternates and unit prices in a bid estimate?

Alternates are priced as separate line items with their own quantities, units and waste factors, so the base bid stays clean and each alternate can be accepted or rejected independently. Unit prices for added or deleted work are built from the same labor rate and material pricing as the base scope, with markup and contingency stated on the line rather than buried in the rate.

Do you estimate for trade contractors as well as general contractors?

Yes. Trade contractor estimating is scoped by division, so a concrete package covers Division 03 formwork, reinforcement and placed concrete, while an electrical package covers Division 26 feeders, branch wiring and devices. The estimate follows your bid package scope of work, and we flag exclusions and clarifications you should carry into the subcontractor bid.

Send drawings for a scoped estimate

Send your plan sheets, specification sections and any addenda, along with the bid date you are working toward. We review the set, confirm the divisions in scope, and return a written quote with the fee and delivery date before plan review begins.
