Why this procedure was chosen
The consultant developed the detailed design and build to print drawings for the advanced transition works. During the construction phase the consultant is required to be available to respond to technical queries that may arise on their design. To potentially appoint another consultant at this stage may inadvertently introduce design safety risks as they would not be aware of the original design intent or have been involved in the complex design integration with mechanical and electrical designers. There would also be a disproportionate mobilisation period and knowledge transfer from the incumbent to the potentially new contractor that would outweigh any perceived commercial benefits.
