How to Handle Scope Creep on a US Construction Project
Scope creep – the gradual expansion of a project beyond its original agreed scope – is one of the biggest margin killers in US construction. The work keeps growing; the price stays fixed. Here’s how to stop it.
What Scope Creep Looks Like
- “While you’re here, can you also…?”
- “I thought that included…”
- “The plans show it this way but can we change it to…”
- Tasks that logically seem connected but weren’t in the original quote
Every one of these is a legitimate change order opportunity – if you handle it professionally.
The Change Order: Your Essential Tool
A written change order is required for any work outside the original contract scope. Before doing any additional work:
- Stop and document the requested change
- Price the additional labor and materials
- Present a written change order to the client
- Get their signature before proceeding
Your change order should say: “This change order covers [specific additional work]. Additional cost: $[amount]. This amount will be added to the contract total. Customer signature required before work proceeds.”
In most US states, contractors who perform extra work without a signed change order have limited legal ability to collect payment for it.
How to Have the Conversation
“That’s not something I included in the original quote – it’s a bit of additional work. Let me put together a quick change order so we’re both clear on the cost and you can decide if you want to add it.”
Most reasonable clients accept this without issue. It’s professional, not confrontational.
FAQs
What if a client refuses to sign a change order? Don’t do the work. Politely explain that you’re unable to perform additional work without written authorization – this protects both parties. If they insist the work was part of the original scope, refer back to your written contract for what was included.
Can I enforce a change order in US court? Yes – signed change orders are legally binding modifications to your original contract. Unsigned ones are much harder to enforce. Always get the signature.
