JCT Sub-subcontract
The Joint Contracts Tribunal (JCT) was formed by the Royal Institute of British Architects (RIBA) in 1931 when the first JCT standard form of building contract was issued. It now produces a range of standard forms of contract for the construction of buildings accompanied by guidance notes and other standard forms of documentation.
As buildings have become increasingly complicated, so it is less and less likely that any one contractor will have the required skills to carry out all of the works necessary to construct them. As a result, a supply chain is likely to be created, consisting of an interconnected hierarchy of supply contracts that together will carry out the works.
A subcontract is an agreement between the main contractor and an organisation or individual to perform a portion of the works for which the main contractor was contracted.
A sub-subcontract is an agreement between a subcontractor and an organisation or individual to perform a portion of the works for which the subcontractor was contracted.
The JCT Sub-subcontract (SubSub) is designed for use on sub-subcontract works where the main contract is a JCT contract and sub-contracts are one or more of the JCT sub-contracts.
It can be used on a standard sub-contract, and also where the works (sub-subcontract or sub-contract) are intended to be carried out in sections. The works can be based on remeasurement or on an adjusted sub-subcontract sum. It is not suitable where the works are of a complex technical nature, or if they require full back-to-back provisions with the sub-contract.
