1 6/14/2022 7/13/2022 Electrical Drawing EL101 B61 Ground Level Lighting Plan. Storage Room 001C the fixture does not have a designation. Please verify the fixture type.

The fixture in 001C should be Type A.

2 6/14/2022 7/13/2022 Electrical Drawing E-600 One-Line Diagram. The new circuits shown out of MP-11 are shown with a neutral. Panel MP-11 does not have a neutral, it is a 240V 3PH 3W panel. Please advise which panel to use for the new 600A Circuit to the trailers and the 20A 120V circuit for the lighting.

Along with these responses, we will be providing an addendum to add a transformer from 240 delta to 240 single phase/ 120V.

Basis of Design: Square D dry-type transformer EE167S3H.

This transformer will be placed just ahead of the main trailer disconnect.

3 6/16/2022 7/13/2022 We noticed that there are some fire /smoke damper controls in the HVAC / Siemens controls that are pneumatic in the construction area. Will those be changed out to electric actuators or remain pneumatic?

Statement of work indicates for all pneumatics to be replaced inside the renovation spaces. All pneumatics tied to the renovation and new equipment should be updated to DDC.

VA to confirm and comment further on equipment not being replaced or relocated in a future amendment.

4 6/16/2022 7/13/2022 Please advise if the designated SSHO and Competent Person role can be fulfilled by the site superintendent?

The competent person(s) can be multiple people depending on the type of hazard, trade, and/or task. The SSHO and CPs should not be the same person, the CPs are subcontractors.

The SSHO is the prime contractor. The prime contractor's superintendent can have no more than two roles. Spec 01 35 26, 1.7 "SSHO and CP"

5 6/16/2022 7/13/2022 Will the SSHO be full time separate person? Does not have to be.

49 6/17/2022 7/13/2022 The Project Narrative states that a new Telecommunications Room

(006) will be constructed and relocated from Room 005C. However, on the Technology Drawings, there is not Room 006, Rooms 006A and 006B are waiting rooms. It appears that Room 008A may be a TR but no details are provided for this room. In addition, on Sheet TN102, Note 18 states to reuse existing racks and add new Patch Panels as required. Can the government please clarify if here will be a new TR or if we are to reuse the existing racks. If a new TR is to be constructed, can the government please provide a detailed room layout to include racks, power distribution and cable tray requirements?

As part of another project, the current telecom room 005C is being relocated to 006. This relocation is out of the scope of work of this project.

50 6/20/2022 7/13/2022 Sheet AE021- The demountable is called out as a 6” wall. Can this be a 4” wall? DIRTT typically only does 6” walls when there is plumbing or med gas. They can do the 6” wall but would need to check with their engineering department to see if they can put their standard pivot door into a 6” wall.

R1- VA provided/VA Installed.

51 6/20/2022 7/13/2022 There is currently 1 door specified. It is door 003c. I see that as a solid pivot door.

a. Will that be a custom stain to match or a standard wood finish?

b. It is also called out as HM-1 for the hardware. I don’t see and

HM-1 and I didn’t see door 003c called out in the specs.

c. The door is called out as 7’-0”. Can this be a full height door at

7’-8” vs a 7’ door with a solid story on the top?

003c is part of DIRTT system and will be VA provided and VA Installed

a. NA

b. NA

c. NA

52 6/20/2022 7/13/2022 Sheet TN 101 and TN102- Note #17 calls for 2” conduit to location of TV.

a. Typically this application uses a ¾” conduit but can do a 1” but would need approval on design for it. Would 2@ ¾” conduits work?

b. Does the VA require an empty box, faceplate or anything else here? If so, at what height?

a. This conduit is intended to direct a VGA and HDMI cables from the side wall to the TV. A smaller conduit would not be large enough. Refer to Detail 3 on Sheet T-500.

b. Also refer to Detail 3 on Sheet T-500 for faceplate configurations. Standard elevation is 18 inches unless noted otherwise.

53 6/20/2022 7/13/2022 Sheet AE200 and AE201. It looks like the DIRT walls are going to gyp at 7’-8” as a typical. There is 1 area on the ground level where the gyp goes to 7’-7” and 2 areas on Level 1 that go to 7’-10”. Does the VA want us to have the DIRTT walls transition in height there or is the contractor to build out these walls in gyp?

Contractor to coordinate furr down heights with VA and DIRTT manufacturer.

54 6/20/2022 7/13/2022 Classroom 002B’s Fire Alarm Device Plan depicts a speaker/strobe device near a DIRTT wall. Is this to be ceiling mounted or integrated into the pre-fabricated wall system?

Ceiling Mounted

55 6/23/2022 7/13/2022 The Furniture, Fixtures, and Equipment Schedule on AE102 says the demountable partitions are to be VA provided and VA installed.

Can you confirm this?

Yes, VA provided/VA Installed.

56 6/23/2022 7/13/2022 Can the A/E clarify the Legend Symbols and Hatch Patterns on CS002? They do not match the drawings.

a. The hatch pattern for new 6” concrete is on the drawings but it is greyed out. How should we interpret this?

b. There are areas where the diagonal line hatch pattern for new 5” concrete is grayed out. How should we interpret this?

c. There are 2 different areas where the diagonal line hatch pattern indicating new 5” concrete do not run the same direction. Are both of these areas to be new 5” pavement?

d. There are areas where the dotted hatch pattern indicating new 6” concrete runs underneath the diagonal hatch patter indicating new 5” concrete. Is the intent to have 11” of concrete? Please clarify.

The new parking lot shall have 6-inch concrete in the drive aisles and 5-inch concrete in the parking stalls.

Other “cross hatch patterns” represent pavement striping.

An updated drawing can be provided.

57 6/24/2022 7/13/2022 Page AE104 states that ceramic wall tile will be installed in the bathrooms 176 & 177. Page AE400 shows these wall areas are out of contract.

Please confirm if the contractor is responsible for installation of ceramic wall tiles per the finish schedule on sheet AE104 or if these areas are “not in contract”.

The gray hatch is showing existing walls, New wall tile is Contractor’s responsibility
