Sub-clause 20.1 indicates in the 6th paragraph that the Engineer may make detail comments if the Contractor’s claim is disapproved.
Two paragraphs later, sub-clause 20.1 states that the Engineer proceeds in accordance with sub-clause 3.5.
A Contractor has insisted on the Engineer’s determination of a claim that the Engineer has disapproved. Does the Engineer proceed with sub-clause 3.5 if a claim is disapproved?
If the Contractor is not able to provide sufficient particulars to demonstrate the basis of claim is there further need for the Engineer to act under sub-clause 3.5 after giving details comments?
The Contractor can refer the Engineer’s disapproval as a dispute under sub-clause 20.3. Is that the proper contractual procedure for the Contractor if the Engineer’s decision under sub-clause 20.1 is not satisfactory?
