The Standard Building Sub-Contract with sub-contractor’s design is made up of two parts: the Sub-Contract Agreement (SBCSub/D/A) which includes the Recitals, Articles and Sub-Contract Particulars, and the Sub-Contract Conditions (SBCSub/D/C).
It is for use when the main contract is one of the Standard Building Contracts (SBC/Q, SBC/XQ, or SBC/AQ), where the main contractor is to design specific parts of the works (Contractor’s Designed Portion), and where the sub-contractor is to design part or all of the sub-contract 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).
