1 Will electronic bid submissions be allowed or do the proposals need to be hand delivered or delivered by courier?

n/a The current bid is intending to have bids done at the address as listed in the solicitation.

2 Drawing MD101, Note M4 states “completely remove existing VAV and all associated ductwork,…..controls…”. The controls (i.e. VAV controller and room Tstats) in these areas were recently replaced and are still under warranty. Can the contractor remove the controllers and reinstall them on the new VAV boxes if the honor the warranty?

n/a Follow the design plans. This project will provide new equipment fit for use and warranteed under this project.

3 Drawing MH101 indicates Key Notes that show VAV‐06, 08, 10, and 12.

However, there are several labelled VAV‐06A on the drawing. What does VAV‐06A mean or indicate?

Guidon ‐ Refer to VAV schedule on MH001. Remark #3 reads" Boxes noted on the floor plans with an "A" are to be cooling only and not provided with a reheat coil

4 Drawing MD201 – New work is indicated in bold print. However, there are a number of areas that are in included in the phased work but not shown in bold on this drawing.

For example, the Exam Rooms are not shown in bold. Does this mean that NO mechanical work (including no controls) is required in these area?

Guidon ‐ Refer to all documents for exact extent of work.

Items shown in bold are to be removed, but if additional items are required based on entire scope of work then it is the contractor's responsibility to perform all required work.

15 The humidifier section of the AHU is not specified on the drawings nor specifications, yet the controls drawings indicate that there will be a humidifier in the unit. Please clarify.

Guidon ‐ There is to be no humidifer in the unit. Ignore this part of the control schematic.

16 Steam piping to the AHU humidifier is not shown on the piping drawing

MP101.

Guidon ‐ There is to be no humidifer in the unit.

17 The AHU detail, on drawing MH201, shows a final filter section downstream of the supply fan. This is not consistent with the controls schematic on drawing MH004. Please clarify the layout of the filters and provide additional specifications as needed.

Guidon ‐ The final filters are to be monitored the same as all filters.

18 There is no specification section included for the VFDs. Please

Guidon ‐ There is no VFD specific specificaiton in the VA TIL.

19 On the Finish Schedule, Room 1452 is indicated to receive SVT.

However, SVT does not appear on the Finish Legend or Project Manual. Please confirm the specs for this material.

Guidon ‐ This is Standard Vinyl Tile (SVT). This is a 12x12, Armstrong, Fortress White

20 The following Rooms have contradicting Floor/Base finishes between the Finish Schedule & Finish Plans. Please confirm what materials are going in the following rooms, or if current finishes are to remain:

oEquipment Storage 1454

(LVT/SVT)

oNurse Sta on 1475 (LVT/WSF) oWai ng Room 1477 (LVT/ETR

SVT)

oSupervisor Office 1479

(CPT/ETR CPT)

oStorage 1489 (SVT/ETR SVT) oComp & Pens Staff 1490

(LVT/ETR SVT)

oSecrete Office 1492 (CPT/ETR

SVT)

oDoctor Office 1494 (CPT/ETR

CPT)

oNurse Sta on 1496 (CPT/ETR

CPT)

oDoctor Office 1498 (CPT/ETR

CPT)

Guidon ‐ 1454 is LVT, 1475 is WSF, all other floor finishes are existing to remain. The SVT or CPT indicates what is existing.

21 The specs are not real clear. I think looking at the door schedule it notes them to be aluminum ‐ Is that correct?

Guidon ‐ For the Coiling Doors, yes.

22 I also want to confirm when you need the 4 doors ‐ are they all going in phase 5 ‐ and when are they needed (month, year)?

Guidon ‐ These are in Phase 1 per GC101.

23 Also there appears that all the doors on the door schedule are 10’ high. Is that the ceiling height or is that the bottom of the box. Reason I ask if I quote 10’ high and you want what is shown then it should be 10’6” because that size is a different price. See the AE601 #15. And on the same sheet #14 does not work the rails / guides are larger than that. A shutter as shown can only be made to 9’ clear height so the rails / guides are larger with a full size doors as attached brochure shows.

Guidon ‐ The ceilings are 9'‐0", The bottom of the box is at +/‐ 9'‐6" AFF. The dimension is to the center of the box enclosure. Detail #14 and #15 includes steel to brace the jambs/rails. Size/space constraints are as drawn.

24 We have attached a brochure for the potential door system, is this the correct type of door?

Guidon ‐ Yes

25 Can you verify that you really want a control station on both sides of the doors. Usually these are protecting some of the equipment.

If that is the case I don’t think there is really any room for someone to actually activate the door from the inside of the room.

Guidon ‐ Yes

The tagged note D1 calls for the removal of a panel and associated feeder completely back to the upstream panel. There is nothing on the current power riser diagram indicating where this panel is located nor the size of the feeder.

Please provide a location where the upstream panel is located and the corresponding feeder size.

Guidon ‐ refer to revised drawing EJ‐200, dated 07.23.20 for clarification.

The tagged note D calls for the removal of two VFDS to mechanical equipment being removed. There are no mechanical schedules noting what this equipment is and the sizes of the VFDS being removed.

The associated conduit and wire need to be removed as well. Please provide the missing information.

Guidon ‐ refer to revised drawings ED201 and EJ‐200, dated

07.23.20 for clarification.
