| TITLE: Renovate Bldg 1040 | |
| QUESTIONS | ANSWERS |
| Can you confirm that the primary focus of the project scope aligns with the outlined specifications in Attachments 1 through 3? | Yes the building shall be renovated IAW the specifications provided. |
| Are there any additional considerations or documents required for submission beyond the bidder’s checklist and specified attachments? | Please refer to the solicitation for the documents you are required to submit. |
| Is there an Asbestos Inspection Report for this project or Building 1040? The Demolition Plans, General Notes, Section E, states the following: |
THE DRAWINGS DO NOT CONTAIN THE INFORMATION CONCERNING LOCATION OR PROCEDURES FOR ABATEMENT OF EXISTING HAZARDOUS MATERIALS SUCH AS ASBESTOS, LEAD-BASED PAINT, OR MOLD. THE CONTRACTOR SHALL CONTACT THE CONTRACTING OFFICER FOR INFORMATION REGARDING SUCH MATERIALS.
| No asbestos is indicated with environmental report. No known ACM in hazard abatement plan. |
| Drawing F-001 Zone 3 Hatching excludes: |
a. 129 Vestibule – Included in FX101 Fire Protection Schedule – Sector A , Note 7
b. 130 Men – Included in FX102 Fire Protection Schedule – Sector B, Note 5b.
| Please clarify Zone of these two rooms. | Room 129 and 130 are not inside the secure boundary of Zone 3. See sheet AE150 for secure boundary locations. |
| Drawing F-001 Zone 1, 2, 3 & 4 Zone Control Valve Assemblies. |
a. Are Zone control valve assemblies to be installed inside or outside of the hazard areas?
b. Are zone control valve assemblies to be installed above ceiling, or along wall below seven feet above finished floor?
| c. | If zone control valve assemblies are installed above ceiling, will portable ladder access be acceptable, or will special access be required to reach valves? | Zone control valves are to be installed above the ceiling outside of the secure area. |
| Specification 21 13 13 § 2.3.2 permits Braided flexible sprinkler hose if AHJ allows. |
| a. Please confirm if Braided flexible drops are allowed by the authority having jurisdiction. | AE has no concerns with allowing braided hose. | |
| Specification 21 13 13 § 2.3.4.2 requires check valves to meet the requirement of MSS SP-71 for Type 3 or 4. This requires check valves to be flanged connection, with no ports for drains. There are a limited number of manufacturers (1 or 2) for these type check valves. These type check valves are not economical. May check valves that are UL listed for Fire Protection or FM approved for fire protection that do NOT meet the requirement of MSS SP-71 for Type 3 or 4 be utilized? | The UFGS requires check valves to meet the requirements of MSS SP-71 type 3 & 4. MSS SP-71 type 3 listed valves have a “clear” waterway, meaning that with full flow the hangar assembly will clear the waterway entirely. This must be met unless there are no products available. | |
| Plan Sheet AE602 shows an Aluminum Storefront “E”. Please advise us of the location that this storefront is to be installed. | Storefront 'E' is an extra elevation and not included in the project. Sheet AE602 has been modified to eliminate Storefront 'E'. See Addendum 01. | |
| Has the Plant and Equipment Schedule been completed and included? |
| a. Is this statement referring to Section 00 10 00 – Solicitation, Contract Line-Item Number (CLIN) Schedule on page 5 of the Solicitation? | All schedules will be provided by the awardee. | |
| In the hardware schedule the x-10 lock is not listed in hardware set #14, but door #169A is listed as getting then x-10 lock. | Hardware set #14 is revised to show an X-10 lock. See Addendum 01. | |
| Hardware set #15 is listed as getting the x-10, but door #129A is not listed as getting the x-10 lock on the door schedule. | Hardware set #14 is revised to show an X-10 lock. See Addendum 01. | |
| In set #16, the x-10 lock is not listed in the individual parts but is listed in the operational section. | Hardware set #16 is revised to show an X-10 lock. See Addendum 01. | |
| Section 8 11 13 page 5. |
2.5.1 Hardware for Secure Doors
a. Secure rated doors must have all hardware prepared and installed on the door at the factory, and shipped to the site as part of the door assembly.
| b. Which doors would be considered "Secure Doors"? | Doors with required STC ratings should be a sound-rated door and arrive on site as a pre-assembled factory unit with hardware that is integral to the sound performance of the scheduled door assembly. |
| I have noticed that there is a disparity between the specifications and drawings in terms of the number of doors that require access control. The specifications call for 33 and the drawings call for 29. |
| a. Which number would you like to differ? | Refer to sheets TY-101 and TY-102 for doors that require access control. This should be the 33. See Addendum 01. | |

Should the CTTA require changes from the contract drawings, would the government handle changes to the drawings per FAR 52.243-4 as listed in the solicitation. | Yes | |
| Sheet AE102 & AE103 Keynote 12 instructs the contractor to verify the existing conditions of the walls at the vault area, and repair to 1 hour rated fire assembly. ICD-705 limits the suitable methods of construction for vault walls, floor and ceiling to a higher standard. For pricing purposes, should the contractor assume that a 1 hour rated wall will meet the CTTA requirements for the space? | The walls in question are not required to meet ICD-705, but they will need to be upgraded (if needed) to meet a 1-hour rating. | |
| Compliance with ICD-705 is noted only in the fire alarm sheets. The word “Secure” along with items typical of a SCIF are noted in the architectural sheets. Countermeasures relevant to radio frequency in ICD-705 and ICS-705-1 are not referenced in contract documents. Other divisions (eg. HVAC, Electrical, Plumbing, etc) do not minimize penetrations into and out of the secure areas as required by ICD-705 and or ISC-705-1. For pricing purposes, is it acceptable for the contractor to assume that countermeasures not shown in the documents are not applicable to the project? | ICD-705 is not a requirement for any of the secure boundary walls. | |
| 01 11 00 paragraph 1.3 notes that the contract documents are not intended to be complete. In order for the Successful offeror to accurately price this request for proposal, can the user define what level each of the secure areas are intended to be, and what waivers will be allowed by the CTTA? | Open storage | |

| a. Please describe how Controlled Unclassified Information (CUI) will be identified? | The contractor will not be provided any controlled unclassified information. In a rare situation that it occurs, we will handle it between the contractor and the government. |
| Drawing FA601 references ICD 705 for secure penetrations. |
a. Specification 21 13 13 § 1.1 references ICS 705-1.
b. Are SCIF requirements applicable to any trade other than Fire Alarm?
| c. If so, please identify which trades other than fire alarm are required to comply with SCIF penetration requirements. | Will remove all mentions of ICD 705 from documents.

| For OLI #1 (replacement of all existing windows), The specs are pretty vague about what is wanted. Prints say, “Aluminum Store Front System”. Is standard storefront aluminum acceptable? (metal profile would be 2” X 4 1/2” or 2” X 6”) Will this be center set? Specs lead me to believe these windows will be a kynar color, can you confirm? Prints also show the removal of what appears to be operable windows, replacing them with complete fixed windows, is this accurate? Window Elevations show all new windows to not be divided at all height wise, and be one full glass unit, this accurate? Does the store front aluminum and glass here require engineered calculations? | The storefront elevations are to match existing. The color is a kynar bronze. The existing windows are not operable. No engineered calculations are required unless part of the AT/FP requirements. | ||
| Interior window ‘IN3’ shows on page AE601 to be a standard pass-through window with both sides operable (sliding left and right), using standard 1/4” clear temp.

| Same questions for the two new exterior aluminum door frames and glass for doors 101A and 171A, do these need engineered calculations? Exterior Elevations show doors 101A and 171A to have drawn hatch lines on the bottom sidelights of the door frame where glass would go. What is this representing? Mapes paneling? Please clarify. | Alum doors do not require calculations. See revised door elevations on sheet AE601. |
