The checklist

Check variation instruction

Verify a valid written instruction or direction issued by the authorised representative.

Check notice compliance

Confirm the contractor gave required notice within the contractual time bar.

4

Verify scope of variation

Confirm the variation is within scope of what the principal can instruct.

5

Check whether work is additional

Confirm the claimed work is additional to the original contract scope, not a defect rectification.

6

Review pricing method

Check whether pricing is per schedule of rates, rates pro rata, or reasonable rates.

7

Check supporting documents

Review invoices, timesheets, and material dockets supporting the valuation.

8

Assess margin and overheads

Confirm margin, profit, and overheads applied are per the contract.

9

Assess time impact

Assess whether the variation triggers an EOT claim.

10

11

Prepare assessment
