Amendment 0001 7149424 B150 Provide Four Canopies

RFI Responses:

2. In as much as the existing canopies are being removed in their entirety and replaced with metal canopies of the same relative size; is there really a need for the fire sprinkler specification to call for Fire Protection Company to treat this as a full blown QFPE design project since the heads and piping are going to be duplicated to match the existing and be installed in the same relative locations. Will a NICET III or IV signature on shop drawings and submittal data be adequate for this small dry pipe fire protection project ?

Response:

Reference Amendment 1 response.

3. In the specifications 1.2 system Design, it states the dry pipe systems must utilized nitrogen. This is an existing system with no nitrogen. Please advise whether the contractor is to buy a nitrogen generator to supply the whole building? If so, please provide the system volume of the entire building?

Response:

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. . Spec Section 21 13 16 has been deleted and Spec Section 21 13 16 dated 11/16/21 has been revised to eliminate this requirement.

4. The specification carry several pages about the canopy sprinklers replacement to be hydraulicity calculated. Please advise whether this needs to be completed since this is a replacement? If so, please provide the underground locations, and sizes and a current water flow test?

Response:

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. . Spec

5. The specifications call for a black schedule 40 pipe. Since this is outside in the weather, does the pipe need to be galvanized?

Response:

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. . Spec require galvanized pipe.

6. The spec’s call for a backflow preventer test connect. The dry systems existing do not have any.

Please advise whether these are to be installed on every dry system in the building?

Amendment 0001 7149424 B150 Provide Four Canopies

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. Spec

7. Spec section 05 12 00 1.3 requires AISC Quality Certification for the structural steel erector. This certification has been waived on previous projects for a reputable subcontractor who has 40+ years in the industry and working on Cherry Point & Camp Lejeune. Please advise whether this certification requirement can be waived on this project.

Response:

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. Spec Section 05 12 00 has been deleted and Spec Section 05 12 00 dated 11/16/21 has been revised to remove that requirement.

8. CD01 Elevation view of demo states once the existing sprinkler supply line is cap bases procedure for a fire system impairment are to be followed. Please advise what these procedures are.

Response:

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. Spec Section 21 13 16 has been deleted and Spec Section 21 13 16 dated 11/16/21 in the footer has been added to include the procedures.

9. Can the 120 completion date be extended to 240 days due to the delay’s in steel material?

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments.

10. Spec Section 05 12 00, Paragraph 1.3 indicates that the Structural Steel Fabricator and the Structural Steel Erector required for the project shall be AISC Certified. There are currently no available AISC Certified Erection Technicians in the state that can access MCAS Cherry Point due to lack of interest or criminal history. Also, the cost for the structural steel material will be significantly greater if it has to be sourced from an AISC Certified Fabricator. In addition, the same type of canopy required for this project has been previously constructed at B147 (MACC Solicitation: N400857050470) that did not have this requirement included in the SOW or Streamlined MACC Specs. Can the AISC Certification for the Structural Steel Fabricator and the Structural Steel Erector be removed by Amendment?

Response:

Submit Proposals in accordance with RFP, Specifications, Drawings, and all Amendments. Spec Section 05 12 00 has been deleted and Spec Section 05 12 00 dated 11/16/21 has been revised to remove that requirement.
