Mr. Phelim Devine:

The changes that have been made are final changes that are intended to make the billing compliant. The contractor is well aware of these changes. There has been ongoing communication with the contractor for months now. We give them a list of the changes that are coming. Then there is a process of finalising the changes involved. That goes to the employer's representative, who issues change order. The contractor is well aware of all the changes that come down the line. It is well aware of all the issues with the ceilings, etc. It has been aware of them for months. A tier 1 contractor should be well aware of how to programme for these changes that are coming. That is what it is supposed to do.
