Prime Cost Sum (PC Sum)
Definition
A prime cost sum (PC sum) is a sum of money included in a contract or bill of quantities to cover the cost of specific items, typically supplied or installed by specialist subcontractors, where the actual cost is not known at the time of tender. The PC sum is replaced with the actual cost once the item is procured.
In construction tendering, this means...
PC sums are commonly used for items like specialist fittings, mechanical and electrical equipment, or nominated subcontract packages where the exact specification isn't finalised at tender stage. Managing the delta between the PC sum and the actual cost, and the impact on the contractor's margin, is an important part of commercial management.
