About the company

A construction cost estimator that knows the Illinois construction market

Illinois construction doesn't move at one speed. Chicago's dense mid-rise and mixed-use pipeline runs on a different labor and permitting rhythm than a manufacturing build in Rockford or a grain-adjacent industrial project downstate near Springfield. Estimating Buddies was built around that range, offering cost estimating services in Illinois that price to the region a project actually sits in.

We work directly from construction drawings, architectural plans and project specifications to produce a complete construction cost estimation package - quantity takeoffs, material and labor cost estimating, and a full cost breakdown built on current Illinois labor rates, Illinois material prices and local supplier pricing.

Our estimators support Illinois general contractors, subcontractors, builders, developers, architects and engineers across the Chicagoland construction market, Northern, Central and Southern Illinois alike - and we also handle a construction cost estimate for out-of-state work when an Illinois contractor is bidding a project elsewhere in the USA.

How it works

How the process works, start to finish

Six steps from plan submission to a finished, bid-ready estimate.

01

Send your plans

Construction drawings, architectural plans and project specifications for the scope you need priced.

02

Scope confirmation

We confirm trades, project type and format - preliminary, detailed, conceptual or final.

03

Quantity takeoff

Estimators complete the material takeoff and quantity takeoff trade by trade.

04

Pricing & cost analysis

Costs are applied using current Illinois labor rates, material prices and supplier pricing.

05

Internal review

A second estimator checks quantities and pricing before delivery.

06

Delivery & revisions

You receive the finished estimate with a full cost breakdown, plus revision support.

Software & pricing sources

What the numbers are built on

Software speeds up the takeoff. The pricing source underneath is what makes the number right for Illinois.

PlanSwift

Bluebeam

On-Screen Takeoff

Trimble

RSMeans cost data

Excel estimating workbooks

BIM cost estimating

Digital quantity takeoff

Baseline pricing is checked against RSMeans cost estimating data, then adjusted to current Illinois labor rates, Illinois material prices and market-based construction pricing across Chicago, Aurora, Naperville, Rockford and Peoria - because a Chicagoland unit cost rarely matches one from Central or Southern Illinois.

Accuracy & QA

How we catch mistakes before you see the number

Accurate construction cost estimates come from a review step, not just software output.

QA-01

Quantity cross-check

Takeoffs are checked against the drawing set for missed scope or wrong units.

QA-02

Local pricing validation

Material and labor rates are compared against current Illinois construction pricing by region.

QA-03

Second-estimator sign-off

A second estimator reviews the finished cost breakdown before delivery.

Illinois building codes

Why building codes move your number

Illinois building requirements and local construction regulations directly shape a construction cost estimate - through material specifications, permitting steps and inspection order. We factor code compliance into the number rather than pricing off a generic national baseline.

That includes the fact that the City of Chicago maintains its own building code, separate in several respects from the state's ICC-based code used by most other Illinois municipalities, along with frost-depth foundation requirements driven by Illinois winters and stormwater detention rules common across Chicagoland due to combined sewer system requirements.

What we factor into the estimate

Chicago's municipal building code versus statewide ICC-based codes elsewhere in Illinois

Frost-depth foundation requirements tied to Illinois winters

Stormwater detention and combined-sewer requirements common in Chicagoland

Municipal permit and inspection sequencing by Illinois city or county
