Courthouse Manager Jobs (NOW HIRING)

On-Site Mechanical Project Manager – Federal HVAC Project

Location: Melvin Price Federal Courthouse (East St. Louis, IL) and Peoria Courthouse, Illinois

Salary: $125,000–$160,000 annually, based on experience

Company: Dynaire, a Crete United Company

About the Role

Dynaire is seeking an experienced On-Site Mechanical Project Manager to lead the completion and construction of a major HVAC and central plant modernization project at the Melvin Price Federal Courthouse and Peoria Courthouse. This is a hands‑on, site‑based leadership role for a mechanical construction professional capable of managing a complex, multi‑trade project involving replacement of air‑handling equipment, air‑cooled condensing units, cooling towers, boilers, pumps, chiller equipment, hydronic piping, refrigerant piping, natural gas systems, controls, electrical coordination, structural supports, testing, and commissioning.

The successful candidate will serve as Dynaire's primary day‑to‑day project representative and general on‑site leader at the site, driving the project from the remaining design and procurement phase through construction, startup, commissioning, and final turnover. Because both courthouses will remain occupied and operational throughout construction, portions of the work will be required to take place during nights, weekends, scheduled shutdowns, and other off‑hours, in accordance with project requirements for continuity of building operations.

Dynaire's corporate office is located in Long Island, NY, so the Project Manager must be comfortable working independently on site in Illinois while communicating regularly with Dynaire's corporate and executive leadership through Microsoft Teams and other project‑management platforms.

Following completion of these projects, there may be an opportunity to continue supporting future projects in the Illinois market or transition into a traveling Project Manager role, based on business needs, project availability, individual performance, and mutual interest.

• Monitor project costs, labor, procurement, subcontractor performance, and overall financial progress.
• Review contractor proposals, change‑order requests, invoices, and schedule impacts; create and track change‑order work with appropriate field documentation.
• Manage punch‑list completion, O&M manuals, warranties, record drawings, training documentation, and final closeout.

Communication and Reporting

• Work closely with the engineering team to resolve outstanding design issues while maintaining clear responsibility between construction management and the Engineer of Record.
• Serve as the primary point of coordination between the client, contractors, design partners, and Dynaire leadership.
• Provide regular project updates covering schedule, budget, safety, quality, risks, and outstanding decisions.
• Escalate issues early and present practical, well‑reasoned solutions to keep the project moving forward.

• Strong working knowledge of HVAC and mechanical systems, including AHUs, DX/refrigerant systems, chillers, boilers, hydronic piping, pumps, VFDs, natural gas, boiler venting, DDC/BAS controls, and mechanical/electrical coordination.
• Experience managing mechanical construction within an occupied facility.
• Ability to read and understand mechanical, electrical, structural, and architectural drawings and specifications.
• Strong understanding of RFIs, submittals, procurement, change orders, scheduling, commissioning, and construction closeout.

• Ability to communicate effectively with engineers, subcontractors, vendors, owners, and Government representatives.
• Ability to obtain and maintain required GSA security clearance/badging and site access.
• Ability and willingness to work nights, weekends, and other off‑hours when required by project phasing, shutdowns, or courthouse operating requirements.
