What it's for
Under NEC4, both the Supervisor and the contractor must notify each Defect as soon as they find it, until the defects date. A clear, written notice records exactly what was found, where, and which part of the Scope it does not meet. It also sets the deadline for correcting it.
When you need it
As soon as a Defect is found, at any point up to the defects date.
Who signs it
Version 1 is signed by the Supervisor. Version 2 is signed by the contractor’s project manager. Delete the version you do not need.
What's inside
- Version 1: Supervisor to contractor, with defect reference, description, location, drawing and the Scope requirement not met
- The defect correction period from the Contract Data, when it starts, and the date for correction (clause 44.2)
- A request for the planned correction date and access arrangements where the Client has taken over
- Version 2: contractor to Supervisor, with the defect details and the proposed correction date
- Sign-off for each version
FAQ
- When does the defect correction period start?
- It depends on when the Defect is notified (clause 44.2). The letter has space to state the start date and the date for correction.
- Do I have to notify Defects I find myself?
- Yes. Clause 43.2 requires the contractor to notify the Supervisor of each Defect it finds, not only the other way round.
- What if the Client is already using the area?
- Arrange access with the Project Manager. The letter includes a line asking for this.
- What is [TO CONFIRM]?
- Details only you know: the contract number, the Project Manager’s name, dates and amounts. We never guess these. They appear as highlighted [TO CONFIRM] placeholders, and the letter opens with a list of every one, so you can complete them before it’s sent.
- Can I edit the document?
- Yes. Both options are Word documents you can edit freely.
- Do I still need to review it?
- Yes. A competent person must check every document against the actual site and works before it is used. ClarusDocs gives you a complete first draft, not a substitute for that check.
