Project Engineer - Mechanical Wet Systems

W2 Contract to hire (with benefits)

Overview

The Project Engineer will specialize in the design, installation, and commissioning of mechanical wet systems including HVAC hydronic systems, chilled / hot water distribution, cooling towers, boilers, and related fluid handling equipment. This role combines technical engineering expertise with project management responsibilities to deliver efficient, reliable mechanical systems for commercial, institutional, and industrial facilities.

Responsibilities

• Project Management : Manage mechanical wet system projects from design development through system commissioning; develop and maintain project schedules, budgets, and resource plans; coordinate with mechanical contractors, controls vendors, and other trades; lead project meetings and provide regular status updates to stakeholders; ensure projects are delivered on time, within budget, and to quality standards.
• Design and Engineering : Design hydronic heating and cooling systems, including piping layouts and equipment selection; perform load calculations and system sizing for chillers, boilers, pumps, and cooling towers; develop piping and instrumentation diagrams (P&IDs) and system schematics; select and specify mechanical equipment, valves, controls, and accessories; prepare technical specifications and construction documents; conduct energy modeling and system optimization studies.
• System Analysis and Calculations : Perform hydraulic calculations for pipe sizing and pump selection; analyze system pressure drops and flow requirements; calculate heat transfer rates and thermal loads; size expansion tanks, air separators, and auxiliary equipment; evaluate water treatment requirements and chemical feed systems.
• Construction Support : Review contractor submittals and shop drawings for compliance; conduct site visits to monitor installation progress and quality; resolve field coordination issues and provide technical clarifications; oversee hydrostatic testing, flushing, and balancing procedures; support commissioning activities and system startup.
• Quality Control and Compliance : Ensure designs comply with mechanical codes and industry standards; review and approve material selections and installation methods; coordinate with building officials and inspection authorities; maintain project documentation and as-built records; implement safety protocols and quality assurance procedures.
