Q72. Drawing E1.1 shows ceiling mounted occupancy sensors for rooms 110 and 111. Drawing E‐2.1 calls for bottom controlled receptacles in these same rooms. The Detail on E‐5.1 calls for a wall switch with integral occupancy sensor that controls both the room lights and the bottom of the receptacles and does not call for a ceiling occupancy sensor. Which of these drawings are correct?

A72: The requirement for this project; and the intent of the Design/Working Drawings provided in the solicitation, is that Rooms 110 and 111 will have ceiling mounted occupancy sensors‐with wall switch override. The wall switch with integral occupancy sensor will NOT control receptacles.

Q73. Drawing T‐6.1 calls for a 100 pair OSP copper cable. Is this a new cable?

A73: The 100 Pair OSP copper cable indicated on T‐6.1 is existing.

Q74. If the 100 pair OSP copper cable is new please provide point of origin and routing.

A74: The 100 Pair OSP copper cable indicated on T‐6.1 is existing.

Q75. Drawing E‐1.1 calls out to replace 2 fixture heads on 2 existing light poles. During the site visit it was noted that there is also the same pole and same fixture head on a 3rd pole just North of the Fire Station. Should we include the 3rd fixture as part of this proposal?

A75: Only include the 2 fixture heads on the 2 poles indicated on Sheet E‐1.1. Do not include the replacement of the third fixture in the proposal.

Q76. What is the percentage of the Bid Bond/Guarantee?

A76: 3%.

Q77. Section 08 51 13, Aluminum Windows, paragraph 1.4.3 references Engineers calculations for the windows and to meet “MINIMUM ANTITERRORISM PERFORMACE CRITERIA”.

a. We need to know the Standoff Distance and Blast Weight that we are required to meet.

b. Even though this information is provided, Calculations and Design Analysis are not performed until after Award, and subject to Change Order to the specified materials. Be advised that the specified aluminum framing product(s) as well as the insulating glass unit(s) make‐up may have to be upgraded to meet the final specified mitigation, from final calculations.

c. Are the existing windows Blast Mitigation windows and do they meet the current DOD Antiterrorism Requirements.

1) Plans indicate re‐install of a salvaged window in one location from the demolition. a. If existing windows are not Blast Mitigation Type is this requirement waived at this location and the balance of the existing windows.

2) The new Casement window pair IS, per Spec, to meet the current DOD Antiterrorism Requirements, hence it will likely not match existing, based on the design and formalities of current blast windows. a. Please advise if the perimeter substrate (rough opening structure)has been appropriately verified for installation connection for Blast Mitigation, as the opening is “Existing”. i.e grouted solid, steel‐lined, etc.

A77: The Facility 1713 is typically occupied by less than 11 personnel, and thus is not required to meet ATFP requirements (standoff Distance and blast weight shall not be considered). It is not the intent of this project to replace the existing windows in the facility to meet ATFP requirements. Any new door/window framing and glazing shall only meet conventional construction standards (laminated and tempered where applicable). Additionally, the new windows will still need to be wet glazed, that is, the IG units will need to be held in place with structural silicone sealant instead of rubber gaskets. The IG units will still need to be constructed as per Spec section 08 81 00, 2.2.1, with a tempered outboard lite and a laminated glass inboard lite.

Q78. Per A05 on sheet A‐1.1, it references a bollard on detail F3 on sheet A‐3.1. Can you please provide sheet A‐3.1?

A78: There is no Sheet A‐3.1. Refer to Bollard Detail G3 on Structural Sheet S‐5.1.

Q79. Can you please provide a specification for any and all insulation?

A79: Wall insulation shall be a minimum of R19 batt insulation. Roof insulation shall be a minimum of R31 batt insulation.

Q80. Will a Risk Management Framework per AFI 17-101 be required for the project at Fire Station 2?

A80: A Risk Management Framework will be required for this project per the attached Air Force Instruction (AFI) 17-101 (see attached).
