Households handling revised project scope

The short answer

Record the reason, design effect, cost and timing before approving work. A verbal suggestion on site may affect more than the visible fixture.

Practical workflow

Describe the old and proposed requirement and ask qualified providers about functional, technical and permission implications. Request an updated drawing or specification where needed. Separate urgent protective action from optional changes. Identify who may authorize the change and how approval is preserved.

What a useful handoff looks like

Keep the agreed revision with the original scope and inspection plan. Confirm whether later stages or owner instructions change. Ask for unresolved effects rather than accepting a blanket same as before statement.

Mistakes to avoid

Do not approve work outside your authority or ignore a change because its price is small. Clinical and building suitability require appropriate review.
