AHU 20 with all duct work, electrical, and controls are to be demolished with no replacement.

2. Please provide pictures of all piping exposed in ceilings, walls, and trenches to be replaced.

All piping in the trench area located in 10A are to be replaced with connections being made in the Room 12A as specified on Drawing D102 Sheet Note 3. See bottom of Sheet Plan M101 for Pipe replacement sequence. Pictures provided are a representation of the piping throughout the trench area in Room 10A.

The following photos are of the piping inside of the Crac units:

3. Please provide pictures of hallways and rooms where work is to take place.

Boiler room where AHU 350 VFD is located

Room 12A where AHU 20 Demolition is performed

Room 10A where Crac Units to be replaced

4. Please provide pictures of doors and routes for equipment to be moved into areas where work is to take place.

See below for routes for demolition, entry, and construction staging area.

5. Please provide attendance lists for both Site Visits.

6. Many Leibert units are on back order. Will Period of Performance and/or NTP date be adjusted to make allowance for long delivery time?

Answered on Amendment 0004

7. Starting a 180 day project in August or September obviously has time factor complications related to the Thanksgiving and Christmas/New Year cessation of work. If necessary, can time limits be adjusted to account for work days missed during these two holiday seasons?

Period of Performance is exclusive of Moratorium dates

8. The specs call for one size VFD but the prints (ZME-D-18001750-E102) call for another size, which size is correct? 5HP will work with the existing 15 amp breaker. Resizing will add to the electrical scope of work and cost.

Please utilize 5 HP for the project.

9. In the specs it calls out that the VFD shall be suitable for existing Magnetek Design A 10hp and Design B 30Hp , but on the last page it calls out a 5HP 480V, which way should we price this?

Again, 5HP will work with the existing 15 amp breaker. Resizing will add to the electrical scope of work and cost.

Please utilize 5 HP for the project.

10. For the VFD, the specs call out Type 1, can you tell us if the intent is for this to be installed in an existing enclosure or will it be its own stand alone enclosure?

The contractor shall provide a new standalone enclosure.

11. Can you tell us who is the original installer of the existing fire sprinkler system? Can you share their contact information?

The original installer of the fire sprinkler system is State Systems (901) 531-6550.

12. Can you tell us who is the manufacturer / original installer of the existing fire alarm system? Can you share their contact information?

The facility will be undergoing a replacement of the fire alarm system while this project will be conducted. Honeywell will be the construction contractor and coordination will be with the FAA.

13. The existing piping sits beneath the raised floor which rests on approx 6” steel channels on 2’ centers to support the floor. These channels span the width of the tunnel. In order for the piping to be removed, these structural pieces and flooring will need to be removed. Please advise.

Provided photos of the existing steel beams as they are bolted connections and can be removed. It will be the responsibility of the contractor to re-install the structural support beams once the work has been completed.

14. What materials are specified to be used to seal the pipe trench for this project?

Contractor to seal trench with double layer, low VOC, epoxy coating 3’ up the side of the wall.
