The main contractor for the ABC project expresses his disagreement with our valuation of variation for change of foundation system for the guard house via email. He is very upset that he could not agree with the contract rates for footing as there is no any such item in the contract. Upon receipt of the above email, your group leader has requested you to study the contract documents to check whether or not the statement made by the Main Contractor is correct. She has also requested you to draft a reply to the Main Contractor on the basis of our valuation of variation.
