Nec3 short schedule of cost components

Hi

Does NEC3 TSSC have a short schedule of cost components?

I don’t see one therefore should I just be using the price list in the contract data

No there aren’t schedules of cost components in NEC3 TSC or TSSC. The TSSC does provide a definition of the term Defined Cost though at clause 11.2(2) which should be applied for assessing compensation events.
