Mr. Hubert Loftus:

It is an important point for the Committee of Public Accounts to hear. That structured process, which involves walking through preliminary design, developed design, detailed design and the detailed tender package, ultimately delivers projects for which the final account typically comes within 5% of the contract sum, which is important for the management of taxpayers' money. That must be borne in mind. It should also be borne in mind that it takes time to work through the procurement process. We are always looking to do things better and to innovate. I note the point the Chairman has made. We are looking at increased use of modular building solutions, particularly in light of the Covid situation.
