Construction Assistant Project Managers in Boston command a base salary range of $115K, $161K in 2026, a market-competitive figure that reflects the region’s robust commercial and multifamily development pipeline. With performance bonuses and allowances factored in, total compensation often reaches $127K, $209K annually.
Assistant Project Manager salary range in Boston: $115K, $161K base
Boston’s construction market rewards Assistant Project Managers at the mid-career level with solid earning potential. The $115K, $161K base range reflects real placement data from hundreds of Amundson Group placements across the Northeast and accounts for the city’s cost of living and labor demand.
What drives the spread? Experience, project scale, sector, and employer size are the primary factors. An Assistant PM with 3-5 years managing small commercial builds will land toward the lower end; a candidate with 10+ years overseeing $50M+ multifamily or civil projects will command the upper range. Similarly, large general contractors and construction management firms typically pay 15-20% above smaller regional builders for the same role.
Beyond base salary, construction companies in Boston regularly layer on performance bonuses (10-20% of base), truck allowances or per-diem ($200, $400/month), and quarterly safety bonuses. Total compensation can add 10-30% to your base figure, pushing top earners well into the $190K+ range.
What drives Assistant Project Manager pay in Boston’s construction market
Boston remains one of the most active construction markets in the US, with sustained demand for mixed-use development, institutional building, and transportation infrastructure. The city’s commercial and multifamily sectors are particularly robust, driving consistent hiring and competitive pay for mid-level project professionals.
Labor availability plays a role too. Boston competes nationally for construction talent, and the presence of major universities, research institutions, and healthcare systems creates steady project flow. Companies investing in long-term growth bid aggressively for proven Assistant PMs who can move projects forward without heavy supervision.
Another factor: the region’s union presence and strong apprenticeship programs mean many firms invest in retaining technical talent. Salaries reflect that commitment, employers know that losing a capable Assistant PM to competing markets costs far more than maintaining competitive pay.
Assistant Project Manager compensation by experience level
Experience shapes salary more than any other variable. Here’s how Boston placements typically break down:
- 3-5 years: $98K, $121K base
- 5-10 years: $115K, $138K base
- 10-15 years: $138K, $161K base
- 15+ years: $161K, $193K+ base
These ranges are calibrated to Boston’s current market and assume solid project management fundamentals (scheduling, budgeting, team coordination). Candidates with specialized expertise, heavy highway, complex industrial, or large-scale commercial, often command premiums within or above these bands.
Benefits + total comp beyond base
Base salary tells only part of the story. Boston construction firms typically offer:
- 401(k) matching: 3-6% of base (some firms go to 8%)
- Health insurance: Employer covers 80-90% of premiums
- Truck allowance/per-diem: $250, $400/month for site-based roles
- Performance bonus: 10-20% of base, often tied to project completion, safety metrics, or company profitability
- Continuing education: Many firms reimburse for PMP, DBIA, or safety certifications
When you add a 15% performance bonus and $300/month truck allowance to a $140K base, you’re looking at ~$162K in total annual compensation, well above the stated range.
What Boston construction companies pay top performers
Amundson Group regularly places Assistant Project Managers earning above the typical range. Candidates who combine strong technical skills with business development capability, or who have managed high-profile, budget-heavy projects, often negotiate into the $175K, $210K base range, especially at larger, well-capitalized firms.
The upper tier typically requires 12+ years of experience, a portfolio of successfully closed projects, and demonstrated ability to manage subcontractors, budgets, and stakeholder relationships independently. Some firms offer additional upside through profit-sharing or equity participation for long-term performers.
Boston’s top-paying construction employers (large general contractors, CM firms, and specialty builders in the $500M+ revenue range) don’t hesitate to offer $190K+ base for proven Assistant PMs who can reduce project risk and accelerate delivery.
