Can requirement details for these areas (in question) be provided?

A: Refer to the attached facilities layout. Drawing is not to scale as it only serves as a general planning purpose. Distances are subjected to change based upon a contractor walk-through. Any distances provided in this Drawing are approximations and should NOT be used for ordering materials or determining lengths. Contractors will be required to determining lengths during the site walk-through.
