What does NEC4 clause 60.1(14) mean?

It links the compensation event list to the contract's split of liabilities. In the NEC4 main contract, the liability section lists what the Client carries. Broadly, that is its use or occupation of the works, its own fault or breach, and loss of or damage to things it supplies. It also covers causes treated as outside the Contractor's control, and any extra liabilities in the Contract Data. On an NEC subcontract, read those as your main contractor's liabilities, and check your own subcontract's list. If one of those events happens and affects you, it is a compensation event. So you are not left with a claim outside the contract. To rely on the clause, show the event, that it falls within a liability the contract gives the other side, and its effect on your work. Notify under clause 61.3 within 8 weeks of becoming aware of it. The change to the Prices, your contract price, is assessed under clause 63.1. It is the effect on actual Defined Cost up to the notification and forecast Defined Cost after it, plus the Fee. That typically means repair or replacement, standing time and protection, with the risk allowances clause 63 requires. Where insurance pays for the same loss, the two must be reconciled so the same cost is not paid twice. Two things go wrong most. You repair damage caused by the other side's staff as if it were your own defect, so it is never notified and the 8 weeks pass. Or the cause is disputed, and nobody took a record at the time. Any delay to the Completion Date is assessed separately under clause 63, and that is a job for your planner.
