Definition
A site instruction is a written order from the engineer or consultant to the contractor, to clarify a detail, change a method, stop work or add an item. If it changes scope, quantity or cost it is handled as a variation under the contract.
Why it matters on a project
Verbal instructions on site prove nothing at the final account. Confirming them in writing the same day protects both sides.
Common mistake
Carrying out a change on the strength of a remark during a site visit with no written confirmation, then having it refused in the valuation.
Frequently asked questions
Is a site instruction a variation?
Yes if it changes scope, quantity or cost; otherwise it is a clarification.
What about verbal instructions?
Send a written confirmation of what you understood the same day and ask for a reply.
