Change Order Management: How to Get Paid for Extra Work
Change orders are where subcontractors either make or lose money. Here's how to document, submit, and actually get paid for extra work.
The Change Order Problem
Studies show that:
35% of all extra work goes unpaid
Average change order dispute is $45,000
Most denials cite "lack of documentation"The work gets done. The documentation doesn't.
What Counts as a Change Order?
Extra work includes:
Scope additions not in your contract
Work caused by design changes
Conditions different from what was shown
Delays caused by others
Acceleration to meet compressed schedulesStep 1: Know Your Contract
Before work starts, understand:
What's the notice requirement? (24 hours? 7 days?)
Who do you notify? (PM? Superintendent?)
What format is required? (Written? Email? Their form?)Missing any of these can void your claim.
Step 2: Document in Real Time
At Discovery
Take photos with timestamps
Note the date, time, location
Identify who was present
Describe what's different from contract documentsWithin 24 Hours
Send written notice to required parties
Reference specific contract provisions
Request direction on how to proceed
State that you reserve the right to claim additional costsSample Notice Language
"Per Section 8.2 of the Subcontract, we hereby notify Contractor of changed conditions discovered at [location] on [date]. The conditions differ from Contract Documents in the following ways: [describe]. We request direction on how to proceed. This notice preserves our right to submit a change order request for any additional costs incurred."
Step 3: Track All Costs
For each change, maintain:
Daily time sheets for affected labor
Equipment logs
Material invoices
Rental receipts
Photos of installed workStep 4: Submit Proper Pricing
Change order pricing typically includes:
Labor (with burden)
Materials (with handling)
Equipment
Subcontractor markup (typically 10-15%)
Extended general conditions if applicableStep 5: Follow Up Relentlessly
Set calendar reminders:
7 days: Follow up on submission
14 days: Escalate to senior PM
21 days: Formal notice that silence = approval (if your contract allows)
30 days: Dispute noticeContract Clauses to Watch
Red Flags
"No claim without prior written approval"
"Waive all claims not submitted within 7 days"
"No change order work without written authorization"Better Language
"Failure to respond within 14 days constitutes approval"
"Subcontractor may proceed with disputed work under protest"
"Oral directives shall be confirmed in writing within 48 hours"What to Do When Change Orders Are Denied
Request written denial with specific reasons
Continue documenting all costs
Reserve rights in writing on each pay application
Don't sign lien waivers that waive dispute rights
Consider mediation before litigationThe Hidden Change Orders
Watch for change orders hiding in:
