28.2.1  Material sub-contracts

(a)  The project agreement will specify what type of sub-contracts (including sub-sub-contracts) are to be regarded as 'material'. They will usually include sub-contracts above a specified threshold value, but may also include sub-contracts of a specified duration and sub-contracts for the provision of particularly important or sensitive Contracted Services (such as security services in a prisons project).

(b)  The threshold value will depend on the nature and value of the project and whether the sub-contract is for construction or operation. However, it is effectively intended to represent a material part of the works or operational services (as appropriate).

(c)  Material sub-contracts will be deemed to include the main construction and operations sub-contracts.
