Each option will need to be assessed against relevant access, logistics and construction constraints.

The appointment will include the review and validation of existing project information; coordination and execution of intrusive and investigative survey workstreams; assessment of site access, interfaces, constraints and stakeholder considerations; and comparative appraisal of the options and associated logistics scenarios. The appointed contractor will be expected to provide advice on buildability, temporary works, programme, cost, risk, Principal Designer/CDM matters and whole-life implications.
