Where an interface like this exists, BS 5975-1:2024 clause 8.1.2 states the TWC should manage
the interfaces and where the temporary works scheme involves substantial contributions from
more than one designer, or the TWC requires more technical contribution, BS 5975-1:2024
clause 7.4.2.1 states that a Lead TWD should manage the design interfaces, and their name
should be recorded in the temporary works implementation plan.
