About The Position

We’re looking for a General Superintendent – Mechanical to provide overall field leadership across all mechanical construction disciplines on our power generation and industrial projects. This is a multi-discipline leadership role spanning everything from anchor bolts up: structural steel erection, equipment setting and alignment, piping fabrication and installation, boilermaker work, and electrical systems—all the way through mechanical completion and handoff to precommissioning. You’ll report to the Director of Construction within our matrix organization, with dotted-line coordination to on-site project leadership. This structure ensures you have dedicated craft discipline support while staying fully integrated with the project team on sequencing, schedule, and execution priorities. You’re the person who sees the whole picture—driving cross-discipline coordination, resolving conflicts between trades, and ensuring every craft superintendent and their crews are pulling in the same direction to deliver safe, high-quality work on schedule and within budget.

Requirements

15–25 years of experience in heavy industrial or power generation construction, with progressive leadership across multiple mechanical disciplines.
Proven experience as a General Superintendent, Mechanical Superintendent, or equivalent senior field leader on large-scale projects.
Direct experience on gas turbine simple-cycle, combined-cycle, or similar power generation facilities.
Demonstrated ability to lead and coordinate across multiple trades simultaneously: Structural steel erection, Millwright / equipment setting and precision alignment, Piping fabrication, installation, welding, and testing, Boilermaker / HRSG erection, Electrical installation, cable, and terminations, Crane and rigging operations.
Strong knowledge of applicable codes and standards, including ASME, AISC, AWS, NEC, NFPA, and OSHA.
Proven track record of managing large craft workforces (500+ craft personnel across disciplines).
Ability to read and interpret multi-discipline construction drawings, P&IDs, one-lines, vendor manuals, and specifications.
Strong understanding of construction sequencing from foundations through mechanical completion and precommissioning.
Experience managing area turnover and system-by-system completion strategies.
Experience working within a matrix organization with functional and project reporting lines.
Excellent leadership, communication, conflict resolution, and organizational skills.
Strong commitment to safety and quality.

Nice To Haves

OSHA 30-Hour Construction certification.
NCCER certification in one or more mechanical trades.
Experience on utility-scale or large industrial EPC projects ($200M+).
Familiarity with both union and non-union work environments.
Experience with GE, Siemens, or Mitsubishi gas turbine and HRSG installations.
Experience supporting commissioning, startup, and initial plant operations.
Experience with modular construction and pre-assembled rack/module installation.
Proficiency with construction management software and scheduling tools (Primavera P6, Procore, or equivalent).

Responsibilities

Provide overall field leadership and direction across all mechanical construction disciplines, including: Structural steel erection, Millwright / mechanical equipment setting and alignment, Piping fabrication, installation, and testing, Boilermaker work (HRSGs, SCR systems, stacks, ductwork), Electrical installation, cable pulling, terminations, and testing, Crane and rigging operations.
Directly oversee and coordinate discipline-specific superintendents across all mechanical trades on site.
Own the integrated mechanical construction schedule from anchor bolt installation through mechanical completion and turnover to precommissioning.
Drive construction sequencing and prioritization across disciplines to optimize workflow, minimize rework, and maintain critical path.
Ensure smooth transitions between construction phases—foundations to steel, steel to equipment setting, equipment to piping and electrical tie-ins.
Develop and manage the integrated mechanical execution plan in coordination with project management and planning.
Lead look-ahead planning across all mechanical trades, identifying constraints, resolving conflicts, and ensuring material and equipment readiness.
Monitor and manage overall mechanical manpower loading, productivity, and labor forecasts.
Track progress across steel tonnage, equipment sets, pipe spool installation, weld completion, cable pulls, and system completion metrics.
Manage area turnover sequencing to support system-by-system handoff to precommissioning.
Review and approve discipline-level work plans, lift plans, and execution strategies.
Ensure all mechanical work meets project specifications, applicable codes (ASME, AISC, AWS, NEC, NFPA), and quality standards.
Oversee QC performance across all disciplines—weld quality, bolt tensioning, alignment tolerances, NDE completion, and test pack readiness.
Ensure compliance with all safety policies and regulatory requirements, including OSHA and site-specific rules.
Drive a strong safety culture across all mechanical crews through daily engagement, job briefings, and accountability.
Coordinate mechanical completion activities across all disciplines to support system turnover.
Oversee punch list management, system walks, and closeout activities.
Ensure all mechanical systems are ready for precommissioning, including: Hydrostatic and pneumatic testing, Lube oil and seal oil flushing, Electrical testing, megger, and hi-pot, Equipment rotation checks, bump tests, and uncoupled runs, Steam blow and chemical cleaning readiness.
Interface with commissioning and startup teams on turnover priorities, sequences, and system readiness.
Support initial energization, equipment startup, and performance testing activities as needed.
Report to the Director of Construction on overall mechanical discipline performance, manpower planning, and resource needs across projects.
Coordinate day-to-day execution with on-site project managers and project directors within the matrix structure.
Serve as the primary point of contact between the mechanical construction team and project management, engineering, procurement, and commissioning.
Lead daily and weekly coordination meetings with all mechanical discipline superintendents.
Interface with inspectors, client representatives, OEM field service engineers, and vendors.
Identify and resolve cross-discipline field issues, constructability concerns, RFIs, and schedule conflicts.
Coordinate with civil and site development teams on foundation readiness, access, and area turnover.
Mentor and develop discipline superintendents, general foremen, and foremen across all mechanical trades.
Support project-level schedule recovery plans and acceleration strategies when needed.
