Mechanical Field Engineer

HGA is seeking a Mechanical Field Engineer to provide field engineering and technical support during the construction of natural gas compressor stations. This position serves as an extension of the client's engineering and construction team on-site - supporting the Construction Inspection Team, tracking contractor progress, resolving mechanical RFIs, and maintaining project records through mechanical completion, hydrotest, and turnover to commissioning. The role reports administratively through HGA but takes day-to-day direction from the site Construction Manager.

Primary Responsibilities

Mechanical Engineering Support

• Provide field oversight of piping, compressor packages, and mechanical equipment installation against approved drawings and specifications.
• Coordinate mechanical work with civil, electrical, instrumentation, and commissioning teams.
• Review and respond to mechanical RFIs; support field changes and engineering clarifications; maintain the RFI log.
• Track major equipment delivery schedules and verify contractor-supplied weights/dimensions match design (P&IDs).

Work Planning & Progress Tracking

• Assist with development of work plans, work permits, tie-in plans, gas handling plans, and PSSRs.
• Assist the Construction Manager with Earned Value Management tracking of contractor progress; help identify schedule/cost-reduction opportunities and evaluate Change Orders.

Testing & Commissioning Support

• Assist with hydrotest plan preparation and collection of test records (highlighted P&IDs, test logs, weld maps, NDE reports, calibration certificates, isometric drawings, test charts); upload to the Pressure Test Management Portal.
• Track gas losses for project accounting (Operations retains lead on gas handling/reporting).
• Support mechanical punch list development and pre-commissioning walkdowns.

Technical Documentation

• Maintain mechanical redline drawings and coordinate transfer from field to office for as-builts.
• Compile the project job box (coating/painting reports, corrosion & CP documentation, and other commissioning-required records).
• Maintain a lessons-learned log of construction and operational issues.

Required Qualifications

• Engineering degree, or equivalent field experience in lieu of degree.
• Experience supporting construction of pipeline facilities, compressor stations, gas processing plants, or other heavy industrial projects.
• Experience with mechanical/piping systems, pressure testing, or rotating equipment.
• Willingness to work a 60-hour/week, 6/10 schedule on-site for the duration of the assignment.

Preferred Qualifications

• Natural gas compressor stations or pipeline facilities specifically
• Hydrotest planning and pressure test documentation
• Earned Value Management or contractor progress tracking
• Field engineering/inspection support role on a heavy industrial construction site
