Complete MEP Services
for Illinois Contractors
Expert estimating for HVAC, Electrical, Plumbing, Takeoff & BIM. MWOA certified for Chicago and all Illinois cities. Cold climate specialists.
Illinois Contractors Trust Our MEP Expertise
Illinois, anchored by Chicago's world-class construction market, represents over $70 billion in annual construction spending. From Chicago's iconic high-rises and O'Hare infrastructure to Downstate industrial facilities and agricultural processing plants, Illinois demands MEP estimators who understand cold-climate construction and Chicago's unique building code requirements.
Our Illinois team has deep expertise in MWOA (Mechanical Work Oversight Agreement) compliance, Chicago energy code requirements, heating-dominated HVAC design for harsh winters, and large-scale commercial and industrial MEP systems. We serve contractors across Chicago's Loop, the suburban commercial corridor, and Illinois' industrial hubs.
With 1,200+ Illinois projects and $130 million+ in estimated value, our estimators know the Illinois market inside and out. Every estimate reflects current Chicago-area labor rates and material costs.

Illinois MEP Estimating FAQs
What is MWOA and why does it matter for my estimate?
MWOA (Mechanical Work Oversight Agreement) governs mechanical work in Chicago. It requires specific licensing, work rules, and inspection procedures. Our estimates are structured to be MWOA-compliant, ensuring your bid meets Chicago's requirements from day one.
How do cold Illinois winters affect HVAC estimates?
Illinois heating degree days are among the highest in the US, requiring larger heating capacity, more efficient boilers, and freeze protection for piping systems. Our estimates use ACCA Manual J calculations specific to Illinois climate zones.
Do you handle Chicago-specific energy code requirements?
Yes. Chicago has its own energy code based on the 2024 IECC with local amendments. Our estimates automatically account for Chicago's higher efficiency requirements, insulation standards, and ventilation rates.
