The only rights the Employer has in respect of the cost of correcting a Defect is that in the event that the Contractor fails to correct it within the defect correction period, any costs incurred in having other people correct the Defect are assessed by the Project Manager and paid by the Contractor (clause 45.1).
The Employer therefore cannot recover the cost of providing access if the Contractor has or is intending to correct the Defect within the required timescale.
