NEC ECS: Are people costs deemed to be included within the fee when not identified as Key People in the Contract Data?

Under an option A subcontract the only people included within the contract data were the Site manager & a supervisor. Following a considerable number of compensation events an EOT is to be awarded to the subcontractor and they have provided a quotation including for a quantity surveyor and a planner, both of whom are working within the working areas.

A quantified schedule of rates was also included as an attachment to the contract data showing the buildup of the prelims and again no QS or planner was identified.

Would the subcontractor have an entitlement to include these additional staff within their defined cost of the extension or would it be deemed to be covered within the fee?

The planner and QS are a People cost under the Shorter SCC. See also the first sentence of clause 52.1.
