We are a contractor on an NEC4 ECC Option C and wish to know whether certain people costs are defined cost or part of the fee. The people in question are based at our head office, occasionally attend the working areas and work on the contract for a large portion of the working week (doing planning, quantity surveying, contract administration etc.). They do this work at the head office as well as in the working areas. Are we only able to recover their time spent in the working areas or can we recover all the time spent on the contract regardless of where it is carried out, that is do they fall within the category of people under the schedule of cost components?
