My experience in validating disbursements for interim payments on contracts is that great reliance is placed on the work of quantity surveyors who are able to disaggregate what becomes set in concrete. They are able to separate the steel element, the concrete element and other parts of the physical delivery, and the physical constituent parts of the practical completion of the contract. They would be able to disaggregate back to the source supplying contractors.
