The table below provides a list of the uses of the JCT contract for various procurement routes:
TRADITIONAL | |
Lump sum contract | where the contract sum is determined before construction work is started |
Measurement contract | where the contract sum is not finalised until after completion, but is assessed on re-measurement to a previously agreed basis |
Cost reimbursement contract | where the sum is arrived at on the basis of prime (actual) costs of labour, plant and materials, to which there is added an amount to cover overheads and profit |
DESIGN AND BUILD | |
Package deal or turnkey contract | where the client settles on a complete package, usually to some standard specification from a commercial firm |
Design and build contract | where project documents will be written with the contractor’s design obligations relating to the whole of the works in mind |
Contractor’s design for specific elements only | Strictly, these are not design and build contracts, but traditional ‘work and materials’ contracts which include for limited design provision relating to an identified portion of the work |
MANAGEMENT | |
Management contract | where the management contractor undertakes to manage the carrying out of the work through works contractors, who are contractually accountable to him |
Construction Management | where the construction manager undertakes to manage the carrying out of the work through trade contractors but the client is involved in the directing of the project, and the contracts with the trade contractors are directly with him |
Design – Manage – Construct | This and other variants of management procurement exist but such contracts are invariably on the basis of specially drafted forms to suit the particular situations |
