Contractor has requested a quotation (63.1) for a considerable CE to the contract that introduces a large element of risk to the Subcontractor. SC has revised the quotation 5 times over the period of 2 months on discussions with the Contractor. Contractor instructed SC to proceed with immediate placement of materials on submission of the latest quotation. Contractor has now asked for substantiation related to 20 elements of the quotation, without requesting a re-quotation, and after the instruction to order materials, this information could have been requested 2 months ago.
This is clear deferring tactics and against the spirit of the contract. What is the mechanism under the contract to stop the endless cycle of re-quotations & re-submissions?
