55. QUESTION: Please issue any available as-built drawings to better aid us in our proposal, especially related to MEP items.

ANSWER: Additional as-built drawings are attached to Amendment 0008

56. QUESTION: After reviewing the Phasing plan, it appears swapping Phase 1 and Phase 2 will provide a better work flow, especially for the Mechanical items. Will the swapping of these phases be acceptable?

ANSWER: Contractor to set up detailed phasing plan. Original concept was to have Smitty move once and that is how Phase 1 was decided.

Temporary heating and cooling was discussed. Option for contractor to provide switchover between phases during tenant move also discuss.

Swapping Phase 1 and 2 per the question above would be less problematic since Phase 1 areas (Current Shop and Storage) are conditioned with Roof Top Units. Smitty would move to the existing Shop and Storage prior to start of construction. After the Phase 2 areas (built as the 1st Phase) are complete, Smitty would move into the Classroom areas. Smitty would need to move once more after completion of Phase 1 (Built as Phase 2).

ANSWER (Revised): Phasing has been eliminated; therefore, this question is no longer valid..

57. QUESTION: I have a question in reference to gaining access to the base in order to turn in the Bid Proposal CD’s and Bid Bonds. What is the process for hand delivery of the package?

59. QUESTION: We have a question on the existing electrical service. The drawings indicate that we are supposed to install a new 1200 Amp Main Switchboard next to the existing to be demolished 1200 Amp Main Disconnect and splice on to the 1200 Amp service at that location. From the site visit, it appears that there is a single 4" conduit that feeds a bus duct going into the top of the 1200 Amp disconnect. Based on this we are questioning whether there is actually a 1200 Amp service to the building. Can you confirm that there is a 1200 Amp service running into Mechanical Room 145 that we can splice on to? And if there is not, what should be provided in our bid for this portion of the work?

ANSWER: The electrical service along with the building transformer appear to be undersized. a minimum 425kVA transformer is required with 9 x 500kcmil cables for the three phases, 3 x 500 kcmil for 100% rated neutrals, and 3 x 2/0 for ground to B527. The feeder needs to be upsized to this size due to the ~80 feet distance from the transformer to the MPDP in order to meet NEC voltage drop requirements. The transformer pad will have to be enlarged; new service with conduit run to the facility; and a new transformer installed.

This will have to be scheduled to not interfere with UMB back which is fed from the same transformer.

60. QUESTION: The sign schedule calls for a total of 11 signs, reference drawing A-001, will signs for modular wall system rooms and offices be required? If so, what type of sign is required? Will signs for restroom 138 and 139 be required?
