Quick answer

What Is a Construction Cost Estimate?

A construction cost estimate is a forecast of the total cost to build a project, broken into line items for materials, labor, equipment, subcontracted work, general conditions, overhead, profit and contingency. A professional estimator builds it from measured quantities on the drawings and current unit costs for the project’s location, and states the assumptions and expected accuracy range.

Our construction cost estimating services cover every stage of a project. Early on we prepare cost plans and budget estimates that tell an owner or lender whether the design fits the money. As drawings mature we turn them into detailed, bid-ready estimates organized by CSI MasterFormat division, so a contractor can submit with confidence or a developer can compare bids line by line.

Every estimate starts with a full construction takeoff. We then price each quantity with regional material costs, local wage rates and crew productivity, and add the indirect costs that most often sink a bid: supervision, temporary facilities, equipment, permits, insurance, escalation and contingency. You can see exactly how every number was built — nothing is a black-box lump sum.

Need only part of this? Order a quantity takeoff to price yourself, a material takeoff for purchasing, or a preliminary & budget estimate for early design.

What's included

What Our Construction Cost Estimates Include

Each estimate is complete enough to bid from and transparent enough to defend in a meeting with an owner, lender or subcontractor.

Full quantity takeoff

Every trade on the drawings measured on color-coded layers and linked to the sheet it came from.

Material pricing

Current regional pricing for every material, with waste factors and sales tax applied.

Labor hours & rates

Crew productivity by trade and height, priced at local union, open-shop or prevailing-wage rates.

Equipment & general conditions

Cranes, lifts, scaffolding, supervision, temp facilities, permits, cleanup and safety.

Markups & contingency

Overhead, profit, bonds, insurance, escalation and design or construction contingency.

Scope letter

Assumptions, clarifications, exclusions, alternates and allowances written for your proposal.

Estimate types

Cost Estimates for Every Stage of Design

The right estimate depends on how far the design has gone and what decision the number has to support. These are the estimate types we prepare most often.

How it works

How We Prepare Your Cost Estimate

A clear five-step process with one point of contact and a fixed price agreed up front.

  1. Send drawings & specs

    Upload plans, specs, addenda and the bid form, or share a plan-room link — see what to send.

  2. Scope & fixed quote

    We confirm trades, alternates, labor conditions and due date, then send a fixed price.

  3. Takeoff

    Every quantity is measured on color-coded layers by CSI division.

  4. Pricing & review

    Local material, labor and equipment costs are applied; a second estimator checks it all.

  5. Delivery & revisions

    Excel estimate, marked-up PDFs and scope letter; addenda revised on request.

Accuracy

How Accurate Is a Construction Cost Estimate?

Short answer: it depends on design completeness. Concept budgets can vary by 30% or more; detailed estimates from complete construction documents are usually within a few percent of the bid-day cost. We state the expected range on every estimate using the AACE International class system.

Source: AACE International Recommended Practice 18R-97; RP 56R-08 applies the same classes to building construction.
AACE classDesign maturityTypical useExpected range (low / high)

We improve accuracy with local pricing, a second-estimator review and benchmark checks against cost per square foot for similar buildings. Read more on quality & accuracy.

Pricing

What Affects the Cost of a Construction Estimate?

Estimating fees are quoted per project at a fixed price. These are the factors that drive the quote.

Number of trades

A single-trade estimate takes a fraction of the time of a full multi-trade bid.

Sheet count & complexity

More sheets, details and building types mean more quantities to measure and check.

Design completeness

Incomplete drawings need assumptions and allowances, which take estimator judgment.

Turnaround

Standard schedules cost less than rush delivery for a bid due tomorrow.

FAQs

Construction Cost Estimating FAQs

What is included in a construction cost estimate?

A full estimate includes the quantity takeoff, material and labor pricing, equipment, subcontracted work, general conditions, overhead, profit and contingency, plus written assumptions and exclusions. PES delivers it as an editable Excel workbook with marked-up PDFs.

Fees depend on the number of trades, sheet count, design completeness and deadline. Every project gets a fixed quote before work starts — see pricing or request a free quote.

Most single-building estimates take two to five business days. Large or multi-building projects are scheduled backward from your bid or budget date, and rush delivery is available when estimator capacity allows.

A takeoff measures quantities from the drawings. A cost estimate prices those quantities with material, labor and equipment costs and adds indirect costs and markups to reach a total.

Yes. Early drawings get a preliminary or budget estimate with allowances and a stated accuracy range. We list every assumption so the estimate can be updated as the design develops.

We use RSMeans as one benchmark alongside supplier pricing and local wage rates. RSMeans city cost indexes help adjust national data, but final pricing reflects current market conditions where the project will be built.

Yes — “building cost estimating” is another name for estimating the cost of a building project. Our service covers new buildings, additions and renovations of every type.

Yes. We prepare change-order estimates and independent reviews that compare a contractor’s pricing with our own line by line.
