Construction Law/Vairaiton Rate as per Red Book


one of the itme was executed for three years and paid also for 30 IPC's.  this work is now completed and unit rate was aproved by Engineer and paid also, however Employer approval for approved rate was not taken by Engnieer.  Now after three years, whether Engineer can deduct the amount from Cntractor for not having the approval from Employer?



Yes, the Engineer can deduct the amount from Contractor because the rate was not approved by the Employer. In 12.3, the Contract mentions: "Until such time as an appropriate rate or price is agreed or determined, the Engineer shall determine a provisional rate or price for the purposes of Interim Payment Certificates" and 14.7 says: "The Engineer may in any Payment Certificate make any correction or modification that
should properly be made to any previous Payment Certificate."
So, yes, the Engineer can deduct the amount.
All the best!
