Question/Answer Set 3

• Regarding question #8: if the only way possible to meet the 365 day schedule is to work on three elevators at once, is this going to be a requirement in the specification (work on 3-cars at once which would require (3) crews) or is there an opportunity to extend the schedule so that only one Elevator can be worked on at a time concurrently? The PWS and the Solicitation does not state that 3 elevators need to be worked on at one time. No, working on 3 elevators at one time will not be a requirement. There is not currently an opportunity to extend the schedule.

• Are there LD’s tied to the schedule? There are not liquidated damages tied to the schedule. However, if the schedule cannot be met Consideration may be requested.

Regarding question #3: To clarify, the existing freight elevator is to be demolished and replaced with a passenger elevator? We received clarification from the Air Force Civil Engineer Center (AFCEC) on the necessity of an EMSA elevator. According to UFC 3-490-06, paragraphs 2-2.3, this requirement is exempted as long as the existing shaft/hoistway is maintained. Since we plan on maintaining the current hoistway, we are no longer pursuing the installation of an EMSA rated elevator. The four stop elevator will remain a freight elevator, but as previously noted, will require changing from a winding drum machine to a basement geared traction machine. On-site personnel also verified that there are not counterweights, counterweight rails or guides installed in the elevator shaft, so this work will also need to be completed as part of the modernization.

* Regarding question #5: On a previous Q&A (email dated 7/22) I asked the following question “Are any of the elevators over 150 foot per minute”. the response to this question was that all of the elevators but one (Frt. Elevator) were over 150 foot per minute. This contradicts the response to question #5 stating that “the current operating speeds of the three elevators in building 600 are 25 feet per minute? This was a typo corrected in a previous Q/A. The three elevators in Building 600 operate at 25 fpm and the elevator in building 600 operates at 250 fpm.

* Regarding question #5: The speed on the new Passenger Elevator (existing Frt. Car) shall be increased from 25 fpm to 250 fpm? If alterations to the hoistway are required for proper clearances and/or run-by for the passenger elevator, are said alterations to be part of the base bid or would this be a change-order item once it is determined what the alterations are going to be? With the concurrence of AFCEC, we will no longer be pursuing an increase in operating speed for any of the elevators, unless it is deemed necessary by the pre-construction engineer analysis. The driving factor behind increasing the speed of the 4 stop elevator was to meet EMSA requirements, which as previously stated, are exempted as part of this SOW.

* Regarding question #7: The answer to this question says “we would likely install sump pumps”.

Does “we” refer to EAS making this a “work by others” item? The installation of sump pumps and associated plumbing is a bid item to be performed by the contractor hired to perform this work, and therefore should be captured in the proposal.

UFC 3-490-06, which was previously removed as an applicable document via RFI, has been reinstated as an applicable document per conversations with AFCEC. Per section 1-3 of this document, “This UFC applies to all planning, design and construction, MODERINZATION, repair, maintenance and operation and equipment in new and existing buildings.” Based on this, the Air Force recommends reviewing this document, as well as UFGS 14-21-23, to ensure all planning and construction aligns with these codes.
