JCT Intermediate Building Contracts

The JCT Intermediate Building Contract is designed for construction projects involving all the recognised trades and skills of the industry, where fairly detailed contract provisions are needed, but without complex building service installations or other specialist work. Intermediate Building Contracts are suitable for projects procured via the traditional or conventional method.

The employer is responsible for the design, and this is usually supplied to the contractor by the architect or design team working on the employer’s behalf. If the appointed contractor is to be responsible for designing specific parts of the works, then an Intermediate Building Contract with contractor’s design must be used.

The employer (through its advisers) will also need to provide drawings and bills of quantities, a specification or work schedules to specify the quantity and quality of work at tender stage. When using the Intermediate Building Contract with contractor’s design, the employer must also detail the requirements for the parts of the works that the contractor is responsible for designing.

Intermediate Building Contracts are normally administered either by the architect, quantity surveyor, or a contract administrator.
