Is this permit required? This specification has been amended.

13) Sheet note A on sheet G-101 calls for temporary stair tower to access construction area. Does this mean the contractor will not have access to the pedway through the buildings?

48) Please provide the point of contact for the existing Access Control System and BAS System?

ACS: Tim Huffines (615) 509-6705

VA Energy Eng: George Yousef George.yousef@VA.GOV

The BAS can operate from Alerton, Siemens, or Honeywell.

49) Is this project a re-bid? Has it already been bid before? This is not a re-bid.

50) According to our elevator contractor, the specifications call for the replacement of the existing geared machines and install new Gearless machines and reuse the existing machine beams. This is not possible due to the differences in the foot pattern of a geared and gearless machine. To complete this change in machines, additional support beams will be required to be installed in the overhead (under the machine room) to secure the new deflector sheaves. These overhead support beams will require your Designer of Record to determine. If the goal is to achieve 4000lb capacity and 350FPM, this can be accomplished by installing a new Hollister Whitney #63 Geared machine. This new geared machine will meet all the requirements in the specifications except for gearless. The new geared machine will save money and downtime. We respectfully request the option to install a geared vs gearless machine. Gearless machines are used every day to replace geared machines. The existing Hollister Whitney machine has a direct gearless replacement. The machine beams align over the existing cable drop in which there would be no difference in number and size of ropes. What is required is the addition of new blocking beams for the gearless machine, which sit on the deck in the machine room. There is no need to replace the existing Geared traction Hollister Whitney machine with a direct replacement. This does not improve the efficiency or provide regenerative savings in heat or BTU output. Contractor review engineering information from Hollister Whitney and Imperial Electric for bidding purposes.
