Frequently Asked Questions
The employer assumes the risk of damage to the works after take over, see the fourth main bullet point of clause 80.1. Before that you as the contractor assume that risk, see clause 81.1, and have to repair any damage to the works promptly, see clause 82.1. You are also required to maintain insurance against such damage, see clause 84 and, specifically, the first line in the insurance table.
It seems likely the cost of repair will be less than the excess of your insurance cover, so you would not make a claim under that. But, in any event, you will not be paid by the employer to correct this damage. That applies even with ECC Options C to E (target and cost-reimbursable contracts), where you are paid the defined cost to carry out the works. This is because the costs of events which you should insure against are excluded from the definition of defined cost, see section 7 of the schedule of cost components.
So, in this case, the pavement damage should be treated as a defect. If it will prevent completion (as defined by clause 11.2(2)) occurring, it should be repaired before completion. Otherwise it should be repaired within the timescales set out in clause 43.2.
