Assistant Project Manager

Assistant Project Manager

We are seeking a motivated and detail-oriented Assistant Project Manager to support the delivery of commercial mechanical and plumbing construction projects across MD, VA, and DC.

This is a hands-on role working directly alongside a Project Manager and field Foreman. You will own real deliverables, be on the job site regularly, and be steadily developed toward a PM role over time. Every PM at JCM started by doing exactly what this role does.

JCM specializes in large-scale commercial mechanical and plumbing construction, including:

• Data centers and mission-critical facilities
• Hospitals, medical labs, and healthcare campuses
• Federal and government facilities
• High-rise residential and mixed-use developments
• College and university buildings
• Trophy office and corporate headquarters projects

Key responsibilities include:

• Submittals, RFIs & Document Control
• Equipment Tracking & Procurement
• Project Coordination & Scheduling
• BIM & Prefabrication
• Field Presence & Subcontractor Coordination
• Closeout & Quality

Qualifications include:

• 35 years of experience in mechanical and plumbing project management, project engineering, or a directly related construction role.
• Experience with a mechanical contractor, general contractor, or MEP subcontractor is preferred.
• Field or trade background is a significant advantage - plumber, pipefitter, HVAC mechanic, or any hands-on mechanical/plumbing installation experience. Candidates who came up through the trades and want to move into project management are strongly encouraged to apply.
• Strong working knowledge of mechanical and plumbing systems in commercial or industrial construction, including the ability to read and interpret MEP drawings and specifications.
• Familiarity with mechanical and plumbing equipment - AHUs, pumps, chillers, VAVs, hydronic systems, domestic water, sanitary, and related systems.
• Experience managing submittals, coordinating RFIs, and producing closeout documentation including IOM manuals.
• Ability to read and understand electrical and controls design documents when coordinating final equipment connections with other trades.
• Procore: Required for submittal management, RFI tracking, document control, and daily logs. Strongly preferred; training is available for the right candidate.
• Bluebeam Revu: Required for markup, drawing review, and document collaboration. Proficiency expected.
• Microsoft Office Suite: Excel (equipment logs, cost tracking, procurement logs), Word (letters, reports), Outlook and Teams (daily communication with GC, vendors, subs). Proficiency required.
• BIM / Coordination Tools: Experience attending BIM coordination meetings and reviewing models (Navisworks, Revit, or similar) is a plus.
• Scheduling Software: Familiarity with Primavera P6, MS Project, or similar is a plus.
• Bachelor's degree in Construction Management, Mechanical Engineering, or a related field is preferred but not required. Equivalent field experience, trade background, or vocational training will be given equal consideration.

The right APM has either come up through the field and is ready to grow into project management, or has been working in a PM-adjacent role and is prepared to take on more ownership. Either background works well here. This is a role for someone who is energized by being on a job site, takes pride in keeping their logs and submittals sharp, and wants to be the person their PM and field team can count on. If that describes how you work and where you want to take your career, we would like to talk.

Benefits include:

• Annual bonus eligibility.
• Comprehensive benefits package including health, dental, and vision insurance.
• 401(k) plan with company match.
• Paid holidays and paid vacation.
• On-site fitness facility at our brand-new, state-of-the-art Upper Marlboro headquarters.
• Company outings, team events, and a close-knit culture built around people who enjoy working together.
• Clear path to Project Manager for the right candidate.

Work environment:

This is an active, hands-on role. You will spend meaningful time on commercial construction sites - attending field coordination meetings, conducting site visits, and staying directly connected to project progress. Office time is based at our brand-new, state-of-the-art Upper Marlboro headquarters, approximately 20 minutes from Washington DC.

Construction is a demanding and rewarding industry, and this role reflects that. We are looking for candidates who are genuinely energized by the work - people who want to learn fast, contribute early, and build a career doing something that matters.
