Job Overview:
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.
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
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
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)
Ability to work extended hours, nights, weekends, and shutdown schedules as project needs require
Comfortable working in industrial environments, including elevated work, confined spaces, and outdoor conditions in all weather
Willingness to travel or work at remote project locations
