Job Summary
Airco MEP, a leading commercial mechanical contractor based in Troy, Illinois, is seeking a hands-on Project Manager / Estimator – Commercial Plumbing to help support the next chapter of growth for the business.

This is a key role for someone who can operate across both preconstruction and project execution. The right candidate will be comfortable estimating commercial plumbing work, helping win profitable projects, and then managing those projects from kickoff through closeout.

Position Summary
We are looking for a commercially minded plumbing professional who can wear two important hats.

First, this person will estimate commercial plumbing projects by reviewing plans and specifications, performing takeoffs, building budgets, soliciting vendor and subcontractor pricing, identifying scope gaps, and helping position Airco MEP to win profitable work.

Second, once projects are awarded, this person will manage projects from handoff through closeout, including schedules, submittals, procurement, RFIs, change orders, field coordination, billing support, and customer communication.

Estimating / Preconstruction
• Review drawings, specifications, bid documents, and addenda for commercial plumbing projects
• Perform quantity takeoffs and develop complete estimates for labor, material, equipment, subcontractors, and indirect costs
• Estimate scopes such as domestic water, sanitary waste and vent, storm drainage, gas piping, fixtures, equipment, and related systems
• Solicit and level vendor and subcontractor pricing
• Identify scope gaps, exclusions, clarifications, constructability risks, and schedule impacts before bid submission
• Prepare proposals, bid summaries, and pricing recommendations
• Participate in job walks, customer meetings, and pre-bid discussions as needed

Project Management
• Lead awarded plumbing projects from handoff through closeout
• Manage budgets, buyout, procurement, schedules, submittals, RFIs, change orders, and progress documentation
• Coordinate with field leadership, plumbers, suppliers, subcontractors, general contractors, owners, and internal stakeholders
• Track job cost, labor productivity, committed cost, and forecasting against estimate and margin targets
• Support billing, collections, and project financial reviews
• Maintain strong communication with customers and project partners to ensure quality, schedule adherence, and issue resolution
• Drive project closeout, including punch list completion, as-builts, warranty turnover, and lessons learned

What We’re Looking For
• 5+ years of relevant experience in commercial plumbing estimating, project management, or a combined PM/Estimator role
• Active plumbing license required, or ability to qualify as the licensed plumbing professional for commercial plumbing work in the applicable Illinois / Greater St. Louis market
• Strong understanding of commercial plumbing systems, construction documents, mechanical scopes, code requirements, and field execution
• Experience pricing and managing commercial projects such as tenant improvements, light industrial, institutional, municipal, healthcare, education, or similar facilities
• Ability to read plans/specs, perform takeoffs, build budgets, and manage awarded work with limited oversight
• Strong grasp of submittals, RFIs, procurement, scheduling, job cost tracking, billing, and change order management
• Strong communication skills with customers, GCs, field teams, and company leadership
• Proficiency with estimating software, Excel, and standard project management/document control tools

Preferred Qualifications
• Experience with design-build, negotiated, and plan/spec commercial plumbing work
• Familiarity with labor coordination and working alongside field foremen/superintendents
• Existing relationships in the Metro East / Greater St. Louis commercial construction market
• Mechanical degree, construction management background, trade background, or equivalent field experience
• Experience with related mechanical scopes such as hydronic piping, medical gas, process piping, or light HVAC coordination is a plus
