Use of a Generic TMP on a Site Specific Worksite

Potential Use Case:
There is a vertical building project which requires a CAR at a specific location.

Traffic Management is only required on an ad-hock basis - such as when trucks are delivering to site. Different TTM companies may provide TTM services throughout the duration of the project each using their own TMP methodology.

A TTM company would like to use a Generic TMP for this work.
