Mechanical and Plumbing Superintendent

Job Purpose Paragraph

The Mechanical and Plumbing Superintendent is responsible for leading the day-to-day field execution of mechanical, plumbing, and related building systems on assigned construction projects. This role oversees MEP trade coordination, installation sequencing, quality control, inspection readiness, schedule performance, and jobsite safety to ensure mechanical and plumbing work is completed in accordance with project plans, specifications, code requirements, and 3i standards.

The Mechanical and Plumbing Superintendent works closely with the Project Manager, General Superintendent, design team, inspectors, trade partners, and commissioning teams to proactively resolve field conflicts, maintain production, and support successful project delivery. This position serves as the primary field leader for mechanical and plumbing scopes, with accountability for coordination, documentation, quality workmanship, and timely system turnover.

Job Duties and Responsibilities

Mechanical and Plumbing Field Operations

• Direct and manage daily field activities for mechanical, plumbing, hydronic, HVAC, domestic water, sanitary waste, storm, gas, and related MEP scopes.
• Supervise mechanical and plumbing subcontractors to ensure work is installed safely, efficiently, and in accordance with approved drawings, specifications, submittals, and manufacturer requirements.
• Coordinate installation sequencing for overhead rough-in, underground plumbing, equipment setting, ductwork, piping, sleeves, penetrations, supports, insulation, controls, and final trim.
• Verify that trade partners have the manpower, materials, equipment, approved submittals, and information required to maintain production.
• Review field conditions and identify conflicts between mechanical, plumbing, structural, architectural, electrical, and fire protection systems before they impact the schedule.
• Support jobsite mobilization, temporary utilities, equipment access, material laydown, hoisting, logistics, and protection of installed work.
• Maintain accurate daily reports documenting MEP progress, manpower, deliveries, constraints, inspections, photos, and field issues.

Safety, Code Compliance, and Inspection Readiness

• Enforce project safety requirements, OSHA standards, PPE compliance, hot work procedures, lockout/tagout expectations, and task-specific hazard controls for MEP activities.
• Conduct and participate in safety meetings, toolbox talks, Job Hazard Analyses (JHAs), and pre-task planning for mechanical and plumbing scopes.
• Coordinate with inspectors, authorities having jurisdiction, commissioning agents, and third-party testing representatives to support timely inspections and approvals.
• Monitor work for compliance with applicable building, plumbing, mechanical, energy, gas, accessibility, and local code requirements.
• Confirm that penetrations, firestopping, supports, hangers, slopes, equipment clearances, access panels, and above-ceiling conditions meet project and code requirements.
• Proactively identify nonconforming work and coordinate corrective action with subcontractors before inspections or turnover milestones.

Schedule and Quality Control

• Develop, maintain, and communicate short-interval and weekly look-ahead schedules for mechanical and plumbing work in coordination with the overall project schedule.
• Coordinate MEP trade sequencing with architectural, structural, electrical, fire protection, low voltage, and finish activities to prevent rework and delays.
• Perform routine quality walks to verify workmanship, alignment, accessibility, equipment installation, labeling, insulation, testing, and system completeness.
• Track MEP production, milestone progress, constraints, and unresolved issues, and escalate schedule or coordination risks to the Project Manager.
• Review layout, sleeves, embeds, rough-in locations, equipment pads, housekeeping pads, and ceiling-space coordination before installation.
• Ensure work is completed in accordance with approved coordination drawings, shop drawings, RFIs, ASIs, bulletins, and field directives.

Coordination and Communication

• Lead or actively participate in MEP coordination meetings, subcontractor meetings, pull-planning sessions, and field coordination huddles.
• Communicate daily with the Project Manager regarding progress, constraints, design conflicts, change impacts, inspection status, and upcoming manpower needs.
• Coordinate with design professionals and trade partners to support timely responses to RFIs, submittal issues, field questions, and constructability concerns.
• Review mechanical and plumbing scopes with subcontractors to clarify responsibilities, interface points, exclusions, schedule requirements, and quality expectations.
• Maintain professional communication with owners, inspectors, consultants, subcontractors, vendors, and internal team members.
• Assist the Project Manager with review of subcontractor pay applications by validating field progress and work-in-place for MEP scopes.

Testing, Commissioning, and Project Closeout

• Coordinate required pressure tests, flushes, inspections, start-up activities, balancing, controls verification, commissioning, and owner training for mechanical and plumbing systems.
• Track deficiencies, punch list items, failed inspections, retesting requirements, and corrective work through completion.
• Support system turnover by ensuring O&M manuals, warranties, test reports, inspection approvals, as-built drawings, attic stock, and training records are complete.
• Verify final record drawings accurately reflect field-installed conditions for mechanical and plumbing systems.
• Coordinate final inspections, equipment demonstrations, system handover, and closeout documentation with the Project Manager and trade partners.

Technical Skills Requirements

• OSHA 30 Certification required.
• Strong understanding of mechanical and plumbing systems, including HVAC, hydronic piping, domestic water, sanitary waste, storm drainage, gas piping, equipment installation, controls interfaces, and system testing.
• Ability to read and interpret mechanical, plumbing, architectural, structural, electrical, and fire protection drawings and specifications.
• Experience coordinating MEP trade partners on commercial, K-12, aviation, municipal, healthcare, or tenant improvement projects preferred.
• Procore project management software experience required; Bluebeam proficiency preferred.
• Working knowledge of applicable mechanical, plumbing, energy, building, and local code requirements.
• Ability to identify MEP coordination conflicts and resolve field issues before they impact schedule, cost, quality, or safety.
• Microsoft Office Suite proficiency, including Outlook, Word, Excel, and Teams.
• Strong written and verbal communication skills with the ability to document issues clearly and professionally.
• Strong planning, problem-solving, decision-making, and organizational skills in a fast-paced construction environment.

Qualifications

• Minimum of 8-10 years of relevant construction experience, including supervisory or superintendent-level responsibility for mechanical and plumbing scopes.
• Proven experience managing mechanical and plumbing subcontractors, schedules, inspections, safety expectations, and quality control in the field.
• Experience coordinating MEP systems from rough-in through start-up, testing, commissioning, punch list, and final turnover.
• Strong leadership skills with the ability to direct trade partners, resolve field conflicts, and maintain accountability for production and quality.
• High attention to detail with a strong commitment to code compliance, documentation, safety, and quality workmanship.
• Ability to manage multiple priorities, field activities, inspections, and deadlines across active project areas.
