A PM agreement is your legal roadmap for a construction project—spelling out who does what, how much it costs, and what happens when things go wrong. Without a solid contract in place, you're exposed to scope creep, budget overruns, and liability disputes that can sink both your timeline and wallet. This guide walks you through what to expect and what to scrutinize before you sign.
The Core Elements You'll See
Every legitimate PM agreement covers the same foundational pieces. The contract identifies the parties (you, the PM firm, and often the contractor), defines the project scope, sets the fee structure, and outlines the PM's specific responsibilities. You'll also find terms about insurance requirements, payment schedules, change order procedures, and dispute resolution.
Read the scope of work section carefully. This is where the PM lists exactly what they'll deliver—site supervision, schedule management, budget tracking, permitting coordination, subcontractor management, or a combination. If it's vague (like "general oversight"), push back and ask for specifics tied to your project type and size.
Understanding Fee Structures
Construction PMs charge in three main ways: percentage of construction cost, fixed fee, or hourly rate. Most commonly, you'll see percentage-based fees ranging from 5–15% depending on project complexity and location.
- Percentage-based: 5–10% for straightforward residential or light commercial; 10–15% for complex projects with multiple trades or tight timelines
- Fixed fee: Works well if scope is locked down early; typical range $15,000–$75,000+ depending on project size
- Hourly: Usually $75–$200/hour; best for small projects or when scope is uncertain
Ask which method applies to change orders. Some contracts tie additional fees only to the increased construction cost; others charge hourly on top. This difference can add thousands to your bill on a mid-sized project.
Key Clauses That Matter
Insurance and bonding is non-negotiable. The PM should carry general liability insurance (minimum $1–2 million for most projects) and errors & omissions coverage. Many states require bonding on projects over certain thresholds—verify your PM carries this and that it's current before signing.
Payment terms typically run net 30 days after invoicing. Check whether the PM bills monthly or on project milestones. For a six-month project, monthly billing keeps costs predictable; for shorter projects, milestone-based fees work better.
Change order authority defines how extra costs get approved. A well-drafted clause requires written approval from you (not just the PM or contractor) before work proceeds beyond scope. This protects you from surprise bills.
Termination clauses spell out what happens if you need to fire the PM. Standard practice gives either party 30 days' notice, with the PM compensated for work completed up to that date. Some contracts penalize early termination—watch for those.
Red Flags to Watch For
Avoid contracts that don't define "project completion" or that make the PM liable for contractor performance without clear limits. A PM can't control whether a subcontractor meets deadlines or quality standards; they can only report and coordinate. If the contract pins all responsibility on the PM, walk away.
Also flag contracts with automatic renewal clauses or vague insurance requirements. Insurance should be specifically named (general liability, property damage, pollution liability for heavy construction) with your company listed as additional insured.
If the PM won't provide references from similar projects or copies of their standard agreement for review before you hire, that's a sign they're not transparent about their process.
Timeline for Review and Negotiation
Don't expect to sign on the first read. Plan for 1–2 weeks of review and negotiation, especially for projects over $500,000. Involve your attorney if the PM handles more than $1 million of your construction budget—the $1,000–$2,000 legal review often saves multiples of that in disputes.
Ask the PM to explain any clause that confuses you. If they can't justify it clearly, it probably shouldn't be in the contract.
If you're comparing multiple PM firms, use the same contract template with each to spot differences in liability, fees, and scope—this makes apples-to-apples comparison much easier. Platforms like Mercoly let you compare trusted Construction Project Management providers side by side, which is especially helpful when reviewing fee quotes and experience against the same criteria.
Frequently Asked Questions
Q: What happens if the project runs over budget—is the PM liable? A: Most PM agreements limit the PM's liability to their fee or a capped amount (often $10,000–$50,000). They're responsible for tracking and reporting budget issues, but ultimate approval of overages rests with you and the contractor—not the PM alone.
Q: Can I negotiate the fee percentage downward? A: Yes, especially if your project is straightforward or in a competitive market. Fees for comparable projects typically range 5–15%, so if a PM quotes 12% for a simple residential build, asking for 8–10% is reasonable.
Q: What insurance do I actually need the PM to carry? A: At minimum, general liability ($1–2M), errors & omissions, and any state-specific bonding requirements. For complex projects, also require pollution liability if demolition or hazmat work is involved.
