Assistant Project Manager

Location: Aurora, CO
Compensation: $83,000 - $100,000
Build Your Career in Mechanical Construction
RK is looking for a Mechanical Assistant Project Manager to help deliver complex mechanical construction projects from kickoff through closeout. You’ll work alongside experienced Project Managers and field leaders while building hands-on capability across scheduling, procurement, cost tracking, submittals, change management, billing, and project coordination.
This is a strong next-step role for someone who enjoys keeping details organized, solving problems early, and connecting the office with the field. You will not just track work—you’ll help keep projects moving.
What You’ll Do
• Support Project Managers with the day-to-day execution of mechanical construction projects.
• Coordinate project documentation, including submittals, RFIs, permits, contracts, logs, meeting notes, and closeout materials.
• Help build, maintain, and update project schedules, budgets, forecasts, and cost reports.
• Coordinate material and equipment procurement with purchasing to protect schedule dates and budget targets.
• Assist with buyout, subcontractor agreements, vendor coordination, and invoice review.
• Track submittal status, approvals, procurement milestones, and long-lead materials.
• Prepare and support billing, schedule-of-values updates, retention tracking, and collections follow-up.
• Help price, document, negotiate, and process change conditions and change orders.
• Partner with field leaders on labor planning, productivity tracking, tool and rental-equipment needs, and jobsite priorities.
• Participate in project turnover, preconstruction, client, coordination, and internal project meetings.
• Support project closeout by maintaining accurate documentation and helping resolve outstanding items.
What Makes You a Fit
• Experience supporting commercial, industrial, mechanical, MEP, plumbing, piping, HVAC, or construction projects.
• Familiarity with core project-management activities such as schedules, budgets, submittals, RFIs, change orders, procurement, and closeout.
• Strong organization and follow-through; you can manage multiple deadlines without losing the details.
• Clear communicator who can work effectively with project managers, superintendents, foremen, vendors, subcontractors, and customers.
• Comfortable learning and using construction technology such as Procore, Bluebeam, Microsoft Project, Primavera P6, Excel, or similar tools.
• A practical, solution-oriented mindset and willingness to take ownership of assigned work.
• Bachelor’s degree in construction management, engineering, or a related field preferred; equivalent construction experience considered.
