ROUND 6

94. What is the purpose of the general exhaust system?

ANSWER: Indeterminate.

95. The documentation indicates that “process systems requirements have not yet been determined”. Will there be a process requirement for this space?

ANSWER: Process systems requirements have not yet been determined. That is still the case.

96. What is “Laboratories” vs. “Utility Areas” when considering that the addition is a one room addition?

ANSWER: The addition may be considered a "Laboratory."

97. There is a pad-mounted switch/sectionalized near an electrical manhole on the north side of the building, labeled “211A244”. Please describe the contents of this enclosure, with the possible intent of primary connection here. Please describe the size of both transformers and services that serve the building.

ANSWER: There are 2 connection points for the new 2mva transformer by Bldg 909..

The first is Z10244, It is currently feeding 2 transformers on the SW corner of 909..

There are no spare 200A connection points unless the new transformer feeds the existing load of one of the existing transformers, otherwise this Z-box would need to be replaced by a new one with 3-200A connection points..

The second is Z11244, It is currently feeding 1 load consisting of a single Z-box supplying 3 transformers, one of them is the newest 1500kva transformer.. It has no spare

200A connection points so it would also need replaced with a new Z-box consisting of 2-

200A connection points.. Both of these proposed connection points are fed from Sub

24A, Fdr 4, which currently has a load of 55 amps and a capacity of 600 amps..

98. Attachment 7, pages 72-74 of 77, lists the applicable UFC requirements, but does not mention any 3-500 series electrical UFCs. Please confirm that UFC 3-501 Electrical

Engineering, UFC 3-520 Interior Electrical Systems, UFC 3-530 Lighting, UFC 3-550

Exterior Electrical, and similar are required design/installation criteria.

ANSWER: The design must comply with all applicable codes and regulations. If the

Engineer of Record determines that this facility meets the criteria that bring it under the control of a particular UFC, then it is the responsibility of that individual to properly apply that code, document it in the construction documents and DA for the project, and submit it for review. A final confirmation of which codes apply to this project will arise from that process. Please consult the following web site for more information:
