Electrical Estimating Software for Illinois Electrical Contractors

Winning Opportunities in the Prairie State

Illinois is one of the most active construction markets in the Midwest — with Chicago's dense commercial corridor, a wave of data center development in the suburbs and infrastructure investment for the state's transportation sectors.

For electrical contractors, that translates to real opportunity. But it also means more contractors chasing the same bids and tighter submission windows.

Illinois runs on local licensing rules, a statewide prevailing wage law that goes beyond federal requirements and a patchwork of NEC adoption cycles — with Chicago maintaining its own electrical code entirely.

McCormick's electrical estimating software gives Illinois contractors the speed and accuracy to compete in this market — automating your takeoff, protecting your margins and keeping your team moving as the pipeline continues to grow.

Critical Factors Impacting Your Illinois Electrical Bids

Illinois electrical bids carry quite a few compliance expectations. Licensing obligations, prevailing wage requirements, code jurisdiction and significant regional variation all factor into your numbers.

Regulation / Factor

Why It Affects Your Bid

Illinois Electrical Licensing — Local Jurisdiction Requirements

Illinois electrical licensing is administered at the local level — there is no single statewide authority. Chicago issues its own Electrical Contractor and Journeyman Electrician licenses through the City of Chicago Department of Buildings, and most collar counties and municipalities add their own registration requirements on top. Estimating labor without confirming the correct local license classification for each jurisdiction puts your bid accuracy — and your ability to pull permits — at risk.

NEC Adoption — Illinois & Chicago Electrical Code

Illinois has no uniform statewide NEC adoption cycle — the code version governing your project depends entirely on the local jurisdiction. Chicago is the critical exception: while its Title 14E code is based on the 2017 NEC, it incorporates heavy, strict local amendments. These amendments mandate rigid metal conduit (EMT) and specific wiring methods where the standard NEC would allow flexible or nonmetallic cable. Labor units built to standard, out-of-the-box NEC rules will vastly underrepresent the actual field labor required on a Chicago-permitted project.

Illinois Prevailing Wage Act

Illinois has its own statewide Prevailing Wage Act — separate from and broader than federal Davis-Bacon. Rates are administered by the Illinois Department of Labor (IDOL) and published each July for every county and craft classification, including electrical. Any public works project with a state agency, municipality or school district must reflect the current IDOL determination for that county — missing it means absorbing the difference out of margin.

Regional Market Variation: Chicago Metro vs. Downstate

Chicago, the collar counties and downstate markets like Rockford, Peoria, Springfield and the Quad Cities each carry different labor rates, supply chain dynamics and project volume. The Chicago metro drives the bulk of the state's commercial and industrial electrical demand — but also carries the highest union rates and the most layered permitting environment. Statewide averages won't protect your margin in any specific market.

Illinois’s construction market is drawing contractors from across the Midwest and each of these factors adds complexity — and cost — to every bid you build.

High-value commercial and data center projects in the Chicagoland suburbs, industrial facility work in the I-80 corridor and infrastructure investment receiving federal dollars make it a market everyone wants in on.

The right estimating system helps you bid smarter in every Illinois market you serve.

McCormick Helps Illinois Electrical Contractors Win More Work

Winning bids in Illinois takes more than competitive pricing. It takes a process that can handle local licensing complexity, prevailing wage requirements and Chicago’s separate electrical code — without slowing your team down or leaving errors in the estimate.

McCormick’s takeoff and estimating software helps your team work through estimates more efficiently and more accurately — automating the repetitive parts of every bid, keeping your numbers tight and freeing your estimators to focus on the details that win bids.

Digital Takeoffs: Built for Illinois’s Fast-Moving Bid Environment

When multiple contractors are chasing the same Illinois project, your takeoff process is either an advantage or a liability. McCormick gives your team the tools to move faster without sacrificing accuracy:

Auto-Count: McCormick automatically recognizes and counts repeated symbols — like outlets, switches and fixtures — across your entire plan set, eliminating manual tallies on dense drawing sets
Auto Home Run: Once counts are locked, McCormick automatically calculates home runs back to the panel — including runs with multiple endpoints — keeping your panel schedules accurate without the back-and-forth
NECA Labor Hours: Access a database of prebuilt assemblies for 120V, 208V and 277V systems — so your team spends less time searching for labor values and more time refining bids that win

The more bids you can turn around accurately, the more opportunities you’ll win.

Pricing Accuracy: Protecting Margin Across Illinois’ Markets

Chicago and downstate markets don’t operate on the same pricing.

Material costs, union labor rates and supply chain lead times shift significantly across Illinois’s distinct regional markets — and what holds in the metro can look meaningfully different a few hours away.

Running statewide averages is a quick way to underbid a job in one market or price yourself out of another.

Real-Time Pricing Updates: McCormick connects directly to supplier pricing feeds from preferred distributors, so your numbers reflect current market conditions — not last quarter's pricing
Preferred Vendor Pricing: Add your preferred local Illinois supply houses to pull regionally accurate material costs without manual lookups or guesswork

When your pricing is current inside your estimate, material cost surprises between bid day and project start become far less likely.

US-Based Support Built Around Your Business

Accurate takeoffs and current pricing only go so far if your team can’t get questions answered during the bidding process.

That’s why McCormick pairs its software with in-house support created to keep Illinois contractors moving.

From day one, McCormick sets your team up for long-term success through structured, personalized onboarding:

Dedicated Trainer: Every new McCormick customer is paired with an expert who learns your business, understands how your team estimates and stays available as your needs evolve
One-on-One Training: Your onboarding is tailored to the specific project types, labor classifications and regional requirements your company handles
Ongoing Access: As Illinois’s regulatory environment shifts, McCormick is there to help you adapt

Illinois Coverage

Illinois construction activity runs well beyond Chicago.

The metro core and collar counties carry the highest project density, but secondary markets across the state each carry their own labor rates, prevailing wage determinations and project profiles.

McCormick serves electrical contractors throughout Illinois — from Chicago's major commercial and industrial markets to regional and secondary markets — providing pricing service compatibility and regional pricing support so your estimates reflect the specific market you're working in.

FAQs: Electrical Estimating Software in Illinois

+How Does Electrical Estimating Software Help Illinois Contractors Win More Bids?

Estimating software takes the slow, error-prone parts of bidding off your team's plate — eliminating spreadsheets, reducing counting errors and giving your team a faster path from takeoff to a submitted number.

In a market like Illinois, where bid windows are short and the competition is dense, that speed advantage compounds quickly.

McCormick removes the most time-consuming parts of takeoff with:

Auto-Count, which identifies and tallies repeated symbols in seconds
Auto Home Run, which calculates runs back to the panel automatically

Combined with a prebuilt assembly database with labor units and pricing already attached, your estimators aren't starting from scratch on every project.

+How Does McCormick Handle Prevailing Wage on Illinois Public Works Projects?

Illinois's Prevailing Wage Act applies to all public works — state agencies, municipalities, school districts and other public bodies — regardless of whether federal dollars are involved.

Rates are published by IDOL each July for every county and craft classification, including electrical.

McCormick lets you build and customize your own labor rate tables, so you can set rates that reflect the current IDOL determination for a specific county and project type. You control the inputs; the estimate reflects them.

+How Does McCormick Handle Chicago’s Electrical Code?

Chicago does not follow the NEC. The city maintains its own Chicago Electrical Code — a separate municipal document with distinct requirements for conduit type, wiring methods, equipment specifications and installation standards that differ from what the NEC mandates.

McCormick doesn’t auto-apply jurisdiction-specific code requirements — that determination lives with your estimator and the plans in front of them.

The assembly database lets you build and save Chicago-specific assemblies — correct conduit types, required wiring methods, code-compliant configurations — so your team isn’t recreating those line items from scratch on every Chicago project.

+How Does McCormick Handle Pricing Differences Across Illinois Markets?

Material costs across Illinois don’t move in lockstep. What you’re paying for conduit, wire or gear in the Chicago metro can look meaningfully different from what a contractor is paying in Rockford, Peoria or the Quad Cities — and building estimates on statewide averages leaves you exposed.

McCormick addresses this at two levels.

First, your team can add preferred local supply houses directly to the software, pulling regionally accurate pricing into each estimate rather than relying on flat national rates.

Second, McCormick integrates with Trade Service — a material pricing database that tracks current costs across the electrical supply chain — keeping your numbers updated as market conditions shift.
