MAHG25-1016 Repair NPS Dorms’ Elevators

Technical Q&A

1. Can the 540-days be extended? With the submittal procedure and manufacturing lead times we feel this will be cutting close with the completion date.

Answer: No, the 540-days cannot be extended. It won’t be necessary since the work phasing change in the attached Addendum 1 will help with time.

2. Instead of saw cutting the lobby floor and removing tile to install the sump pump drain line and clean out, we believe it would be less costly and less time consuming to run the drain line up and out the elevator shaft above the lobby ceiling and then pipe it over into the laundry room and discharge it in the laundry room drain. Will the govt consider this option? Matching the existing tile in the lobby will be extremely difficult due to the age of the tile.

Answer: Yes. The overhead sump pump discharge to the closest laundry room is the preference.

Contractor to follow the Statement of Work regarding the interphasing of the new controllers. Notify the Contracting Officer and the Contract Specialist of any discrepancies post-award.

7. Does the govt have a contact person for the Fire Alarm Systems? In the past JCI will not work with us because we are not the owner of the system.

37. To achieve a new "inground" sump pit, the contractor will need to sawcut, demolish, and excavate a portion of the elevator pit floors to install the new sump pit. This is doable, but the contractor must rely on the VA/DOR to provide direction on the exact location of the saw cutting, demolition, and excavation work. There are many structural concerns when cutting into an elevator pit floor and the contractor cannot take the risks without approval and direction from the VA/DOR. An alternative solution to an "inground" sump pit would be to surface mount the sump pumps and install a cage around them. This is allowable per elevator code (ASME A17.1-2019:

8.7.3.2.2) the contractor is very familiar with installing surface mounted sump pumps in leu of "inground" sump pumps as the elevator code allows it and it mitigates the structural concerns that an "inground" sump pump brings. It is also noteworthy that cutting, demolishing, and excavating a new sump pit can also introduce additional ground water to the pit. Can the VA please confirm if the contractor is to move forward with "inground" sump pumps, or if surface mounted sump pumps are acceptable for this project?

Answer: See provided structure as-built for foundation and slab details. Provide sump pump as indicated on prints and in SOW.

38. Regarding the sump pump additions, is it the government’s desire to have an alarm type system or an oil-water separator?

Perform (3) wall penetrations 1". Can the COR confirm the existing panel has space for the additional requested circuit at each of the requested (7) Locations.

Answer: Yes, there is space.

40. 3.2.5.3.22.1 - This typical installation with available 120v dedicated circuit will be repeated for (6) similar buildings, totaling 7. This specification is under the Electrical heading. Can the COR confirm the scope is also for (7) total sump pumps?

Answer: Yes, 120V for all 7 elevators.

41. 3.2.5.3.20 - Provide new wiring and electrical interconnections and comply with the governing codes. In what areas is this applicable?
