Module 6:  Preventing corruption in project construction

Controls: rates and rate adjustment

  • Implement effective controls over contract rates and any rate adjustment.
  • The procurement controls (covered in Module 5 “Preventing Corruption in Project Procurement”) should ensure that the relevant contract specifies:
    • the rates that will apply
    • the circumstances when rates can be adjusted
    • the procedures for adjusting the rates.
  • Appoint a qualified and honest manager who is responsible for approving any adjustments to the contract rates and who:
    • verifies that there is a legitimate reason for the rate adjustment
    • verifies that the rate adjustment is in accordance with the contract
    • is alert for any suspicious indicators of corruption in relation to the rates and rate adjustment.
  • Require the approval of at least two managers where a rate adjustment has a high cost impact.
