8508642 Specifications 6 of 7 E-201 Plan Drawings

Please explain the constraints of the 4'6" cabinet depth for the exciter cabinets. There does seem to be plenty of space for a larger depth, which would allow for different cubicle configurations that may reduce the length, so that more space is freed-up close to the generator. Would it be possible to have an excitation footprint smaller than 70" x 70" ?

On: Apr 13 2020.

Government Response. . The 4'6" depth requirement is due to access and equipment movement limitations. There are existing governor oil tanks which have a clearance of roughly 5' to the wall, limiting the ability to move equipment with larger dimensions than this. Please advise if the available footprint as shown on the drawings is not achievable, and if not please provide possible resolutions for Government consideration.
