The Supervisor Made Us Open Up Work and Found Nothing

Yes, it is normally a compensation event. When the Supervisor instructs a search for a Defect and none is found, clause 60.1(10) applies in both NEC3 and NEC4 ECC, so a search with no defect found changes the Prices and possibly the Completion Date.

One exception decides most arguments: there's no event if the search was needed only because you gave too little notice of work that blocked a required test or inspection. The instruction itself is at 43.1 in NEC4 (42.1 in NEC3), and our guide to searching for Defects explains how it works.

What to do, in order

  1. Comply. Open up the work. A dispute about the reason doesn't justify refusing the instruction.
  2. Check the reason was given. The Supervisor states one with the instruction. If it hasn't, ask for it in writing the same day.
  3. Record before you break anything: photographs, the labour and plant used, materials wasted, and what happens to following trades.
  4. Invite the Supervisor to witness the opening up and agree the finding on site, ideally the same day.
  5. Notify the compensation event straight away if the Project Manager hasn't. See the timing point below.
  6. Put the work back and quote. Quotations are due within three weeks of the instruction to submit them (two weeks in the NEC4 subcontract).

The timing point

The contract says that events arising from an instruction fall outside the eight-week bar in clause 61.3. A search instruction is exactly that, so a late notification here shouldn't lose you the event. In practice, don't rely on that. Notify once the result is known, because the Project Manager may not realise that an instruction from the Supervisor has become an event, and old claims are harder to evidence.

The result also matters for assessment. Under NEC4, the dividing date for an event arising from an instruction is the date of the communication, so cost incurred after it is judged as a forecast of what would happen at that date, and earlier cost at actual Defined Cost. Your records of the search let you test that forecast.

How the facts change the answer

What happenedLikely position
Search instructed, work opened, all compliantCompensation event under 60.1(10)
A Defect was foundNo event. The Contractor corrects it and carries the search on the basis its main Option gives
You poured over a required inspection point without proper notice under 41.3, and it was opened to allow the checkThe exception applies: no event, even if the work is sound
You gave notice, and the Supervisor missed the inspectionThe exception doesn't obviously apply; you gave what the contract asked. 60.1(11) may also be relevant if the delay was unnecessary
Many areas opened and a Defect in oneExpect argument. Record each area separately and keep your costs apart, so that the sound areas can be priced on their own

What goes in the quotation

Include breaking out, disposal, making good and reinstating finishes. Add testing the instruction required beyond the Scope, standing time for gangs held up, and resequencing of following work. If planned Completion moves on the programme, the delay belongs in the quotation too, measured under 63.5 of NEC4 (63.3 in NEC3). The test delay guide covers the neighbouring event.

Sample notification

"We notify a compensation event under clause 60.1(10). On [date] the Supervisor instructed a search under clause 43.1 at [location], for the stated reason of [reason]. The work was opened on [date], witnessed by [name]. No Defect was found. Notice of this work was given under clause 41.3 on [date]. We await your instruction to submit quotations."

The likely reply

The Project Manager will probably test three things: whether your 41.3 notice was given in time, whether the opening up found anything at all, and whether the quantity of work was reasonable. The last point can be overdone. The Supervisor decided the search area, so you shouldn't be marked down for doing what it instructed. If the reply is that nothing changes, you can dispute it. Other problems of this kind are listed in the NEC questions hub.
