JCT Design and Build Contract
The JCT Design and Build Contract is well established and widely used by those undertaking construction projects where the contractor is to design and build a project.
It offers tried and tested wording on which to base a solid contract. Occasionally there may be a need to amend this contract to suit a particular project. The employer will rarely use design and build in its purest form and will instead commonly specify his or her needs in considerable detail in the employer's requirements.
Take care to amend only what is completely necessary though and it could be that similar projects have encountered the same issues so it’s advisable to check whether an amendment exists that meets your particular requirement. (See Amending standard forms of contract.)
The latest JCT Design and Build Contract was updated in September 2016.
