The Design and Build Sub-Contract is made up of two parts: the Sub-Contract Agreement (DBSub/A) which includes the Recitals, Articles and Sub-Contract Particulars, and the Sub-Contract Conditions (DBSub/C).
It can only be used when the main contract is the Design and Build Contract.
It can be used where the sub-contracted works are fully designed, or if the sub-contractor is required to design all or a part of the works.
It can be used when either the main contract works or the sub-contract works are to be carried out in sections.
It can be be used 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 remeasurement.
Provisions are included for collaborative working, sustainability and bonds (off-site materials and retention).
