Use this document when the role empowered by the contract needs to instruct a defined change to the works or services, whether its price and time effects are settled or pending.
It establishes exactly what is instructed, which documents govern execution, and how unresolved valuation or programme matters are treated, reducing ambiguity between technical direction and commercial agreement for delivery teams.
An authorized contract administrator usually prepares or issues the instruction with design, commercial, and planning advice. The contractor acknowledges receipt; approval and signature requirements follow the actual contract's allocation of authority.
Using one signature to imply approval of scope, price, and time obscures unresolved matters and may misrepresent the recipient's actual acknowledgement.
Illustrative example: an engineer instructs a revised drainage route around an existing foundation. The record identifies the new drawing revision and affected chainages, authorizes the defined work, and marks valuation pending. The contractor acknowledges receipt while submitting a separate assessment of cost and programme effects.
Confirm the adopted edition, local amendments, National Annex where relevant, and contract requirements.
