1. This office reviewed the referenced RFIs for the subject project and provided answers below. Please forward to the contractor(s) for their use in preparing proposals.

(1) With the drawings having an arc flash/coordination study on the drawing sheet E-602, will a contractor provided arc flash/coordination study be required on this project?

Government Response: No. The Arc Flash and Coordination Study shown on drawing E- 602 is for information only. A new, contractor-provided study is not required for this project.

(2) If arc flash/coordination study is required. How far upstream is the contractor supposed to go with the arc flash/coordination study based on General note 4 E-602.

Government Response: See response to RFI #1. No new study is required.

(3) The SOW is unclear on the extent of the telecommunication scope. Please provide more information on the telecommunication SOW.

a) Is the contractor to only provide inwall boxes and "stub-ups" for the base com to install the data? Yes. The contractor’s telecommunications physical scope of work is strictly limited to pathway infrastructure. The contractor shall provide and install all in-wall outlet backboxes, conduits, and pull strings.

b) Is the contractor to provide raceways back to the nearest communication rack in 9001. If so where is this rack located? Yes. The contractor shall install continuous raceways/conduits with pull strings routed from the new outlet locations back to the nearest existing telecommunications cable tray system.

The nearest active communications rack is located in Telecommunications Room 1 (TR-1) at Column Post T18, approximately 100 feet east of the project site. Conduit pathways must route back to the cable tray serving this terminal space.

c) Is the contractor to supply a full telecom system including wall mounted rack and fiber back to nearest telecommunication fiber rack within 9001. If so, where is the fiber rack located? No. The contractor is not responsible for supplying active network hardware, racks, fiber backbones, patch panels, or cabling. All cable pulling, terminations, patch panels, active electronics, and system testing will be performed by the Government (Base Communications) after construction completion.

c. Other? N/A

(4) For any electrical component on the east wall, that is to be removed and reinstalled for the fire rated wall, is abandoned after investigation; can these components be demoed and removed back to source as opposed to being reinstalled?

Government Response: Yes. If an electrical component (e.g., conduit, box, device) that is designated to be removed and reinstalled is found to be abandoned in place, the contractor shall remove the component and its associated wiring back to its source panel or junction box as part of the demolition scope.

(5) Is the Detail 2 on FA-101 applicable to all pipe and raceways through a fire rated wall? Is this applicable for ALL wall penetrations within this space, per detail note "1/2" MIN.

ANNULAR SPACE FILLED WITH FIRE RATED MATERIAL FOR FIRE RATED WALL

OR SILICON FOAM FOR NON-FIRE RATED WALL." Would this also be applicable for vertical penetrations through the mezzanine deck?

Government Response: Yes.

(6) What are the blank boxes drawn on E-101?

Government Response: The blank boxes shown on drawing E-101 represent low-power Government-Furnished Equipment (GFE). Their electrical power requirements are fully supported by, and shall be powered from, the adjacent 120V utility duplex receptacles already shown on the drawings. No dedicated branch circuits, disconnect switches, or specialized electrical hookups are required for this equipment.

(7) Please provide the specifications for the netting system referenced in SOW Section

4.2.6 and Drawing A-103, including the specification for the hardware and attachments needed to install the netting.

Government Response: The Debris containment netting system shall meet or exceed the following requirements:

a) Material/ Polymer type: Knitted High Density virgin Polyethylene (HDPE).

b) Mesh size/ Weight: ¼” x ¼”/ 3.0 – 4.5 ounces per square Yard.

c) Net Breaking Strength: 50 – 100 Lbs. per mesh square area.

d) Flame retardant Standards: meet NFPA 701 requirements, Test Method II.

e) Surface Burning: meet or exceed ASTM E 84/ Class1 requirements.

f) Reinforced Perimeter Border: Hemmed or reinforced edge borders.

g) Reinforced grommets spaced @ a maximum of 18” on center.

h) System attachment to existing girts at a minimum 3 feet above the guard rail with spacing to be a minimum of 18” on center.

i) Reinforced Borders: Must withstand 112 to 180 pounds per fastening point.

j) Hardware Attachment: Secure clips/snap Hooks/ SST wire rope/continuous

Unistrut/attachment to the wall girts above guard railing height and to the toe boards.

(8) What is the required fire rating for rolling steel Door Type 5 (Door 103A) — 1-hour, 2-hour, or 3-hour? The Door Schedule on A-602 lists this door as "90 MIN" (see Fire Rating column), but please confirm this is correct given the door type/location.

Government Response: The rating is 90 Minutes ( 1-1/2 hour) for Door 103A. Refer also to door schedule, door frame schedule and door Type 5 on Drawing A-601. The coiling overhead door systems must be installed per NFPA 80.

(9) Please confirm whether Door Type 5 (103A) is chain hoist operated or specify the intended means of operation.

Government Response: Door Type 5 (103A) is motor operated. Refer to Door Type 5 and Door Schedule on Drawing A-601.

(10) Specifications were not provided for the Type 6 grille door (Door 105A). Please provide the applicable specifications section and/or manufacturer performance criteria for this door.

Government Response: Door 105A is a LHR 3070 Type 7 door with a 45 minute fire rating. Door 105 is a Type 6 steel coiling overhead door. The coiling overhead door system must be installed per NFPA 80. Refer to Drawing A-601. This project does not have Grill type doors.
