Intermediate Sub-contract with Sub-contractor's Design Agreement

Appropriate: for use where the main contract is the Intermediate Building Contract with contractor's design; and where the Sub-Contractor is to design all or part of the sub-contract works (sub-contractor's designed portion).

Can be used: where the sub-contract works and/or main contract works are to be carried out in sections; for sub-contract works that are to be carried out on the basis of an adjusted sub-contract sum (adjustment for variations etc.) or by complete re-measurement of the sub-contract works.

Not suitable: where no sub-contractor's design is involved - consider the Intermediate Sub-Contract (ICSub); where the Sub-Contractor is Named in the main contract.
