An instruction is a request, order or command from one party to another. Typically, the person issuing the instruction requests a course of action or a sequence of events to be implemented by the party that has received the instruction. Instructions usually have to obeyed or implemented.
In construction, consultants, clients and contractors issue instructions continually to ensure buildings are completed as specified, on time and to budget. The most obvious example is the ‘architect’s instruction’ (AI) or 'contract administrator’s instruction’. This is an instruction in written form, usually to the contractor which may be given:
- To vary the works.
- To postpone the works.
- To remedy workmanship, goods or materials which are not in accordance with the contract.
- To sanction a variation made by the contractor.
- In relation to the expenditure of provisional sums.
- To open up work for inspection.
- To carry out tests.
- To exclude persons from the site.
- Any other instructions empowered by the contract.
The contractor must comply with the instruction within certain limitations, but has the right to ‘reasonably object’.
The word 'instruction' may also be used to refer to training.
