18. Q. Advantor is the sole source for the intrusion detection system. The plans and specifications are calling for a fiber optic cable from building 257 to each hangar. Could the base elaborate on where the trenching will be installed for the installation of this cable? Please also provide the location where in building 257 the fiber optic cable will be terminated.

A- There is not intent for a new fiber optic cable between the hangars and Building 257, and indication of such is not apparent in the project documents (Please more precisely identify where it is believed this requirement is shown). Provide communication cabling to Advantor panel per Telecommunications Wiring Diagram on sheet E-503 and location on E-108 for both hangars.

19. Q. On bid option 5 for Hangar 254 (sheet AF-603), the door schedule says replace door leafs only. However, the hardware sets are called out. Please clarify if this alternate is for the doors only, or if we should provide new hardware as well.

A- CLIN 0011 SZCQ139904 Bldg 254 Bid Option 5 is to replace door leaf and hardware.

20. Q. Is the general contractor responsible for the LEED certification? Specification section 018133 clarifies the general requirements and procedures for compliance, but is not clear as to who is responsible for the certifying of the project.

A- General Contractor is responsible for LEED services including; credit documentation, submittal review, submittals, responding to USGBC questions and associated submission/review fees to USGBC for credits outlined in specification 01833 Sustainable Design Requirements.

21. Q. To allow for greater competition could specification section 051200 be amended to include structural steel fabricators and installers that are not AISC Certified Plants and Erectors but do participate in the AISC Quality Certification program?

A- No. AISC Certified fabricators and erectors are required for a structure of this scope and complexity.

22. Q. Spec Section 028200 Asbestos Abatement includes a list of asbestos containing materials to be removed under the base bid in Table 1 on Page 028200-2. Table 2 on Page 028200-3 includes asbestos containing materials to be removed at Building 253 under an "optional line item". Please confirm that this cost is to be included as part of Bid Option 0002 which covers the removal and replacement of the metal roof at Building 253.

A- Yes, it is confirmed that the cost for removal of the ACM identified as to be removed under an "optional line item" on Table 2 on Page 028200-3 is to be included with CLIN 0002 SZCQ139901 Bldg 253 Bid Option 1.

23. Q. Can you confirm that Bid Option 0008, removal and replacement of the standing seam metal roof at Building 254 does not require any asbestos abatement at the roof similar to that of Building 253?

A- CLIN 0008 SZCQ139904 Bldg 254 Bid Option 2 also includes removal of asbestos containing insulating board, similar to CLIN 0002 SZCQ139901 Bldg 253 Bid Option 1. The asbestos containing insulating board is assumed to be present based on historic plans, and is to be confirmed by the contractor. If testing shows the insualting board to be non-ACM, and equitable adjustment will be made.

24. Q. Would you please confirm that Bid Option Item No. 0001 is a total of Bid Option Items No. 0001AA and 0001AB? The reason for this question is because the description of work under Bid Option Item No. 0001 only mentions the "renovation" of Buildings 253 and 254. It does not mention demolition, additions, site work, etc.

A- CLIN 0001 is the total of Sub-CLIN 0001AA and Sub-CLIN 0001AB (Price for Sub- CLIN 0001AA plus price for Sub-CLIN 0001AB equals price for CLIN 0001). CLIN 0001 includes all of the work described in Sub-CLIN 0001AA (SZCQ139901 KC-46A ADAL FUEL CELL BUILDING 253) and Sub-CLIN 0001AB (SZCQ139904 KC-46A ADAL MAINTENANCE HANGAR BUILDING 254), it is the enitrety of the base bid work for the plans and specifications of both projects. CLIN 0001 and its Sub-CLINs are not identified as Options in the Solicitation, Options begin with CLIN 0002.

25. Q. Please confirm or clarify the following items discussed at the site walk: Another walk-thru has been scheduled for February 19th from 10:00 am to 11:30 am.

A- Please reference answer to RFI #2. Please provide names of attendees no later than 18 February.

39. Q. Per the intrusion detection system question on the RFI response: Advantor is requiring a fiber optic cable to be installed from building 257 to each hangar. The drawings and specs do not call for a fiber cable to be installed. We have attached document for a reference.

Please clarify.

A- Fiber to building 257 is available from the comm room in each building. Category 6 cabling is required to the Advantor panel from the comm room. Advantor has included media converters in their proposal to convert the Category 6 cabling to a usable connection with their equipment.

40. Q. We ask for you to amend specification section 321311 part 2.9.1.a to include batching and mixing plants at a greater distance from the project. 10 miles as currently constituted is very restrictive and giving a wider geographic radius will help us provide the NHANG with the best value.

A- The restriction is based on design standards in Specification Section 321311 “Concrete Pavement for Airfields and Other Heavy Duty Pavements” that require a short transport duration. Comply with Section 321311 as written.

41. Q. We ask for you to amend specification section 321311 part 2.9.b to include Massachusetts and Maine DOT certified plants. Such expansion will help us provide the NH ANG with the best value.

A- Plants lacking NHDOT (or NRMCA) certification required by the Specification are unlikely to comply with the distance restriction. Comply with Section 321311 as written.

42. Q. Confirm past experience referenced in Vol 2 Part 1 is not limited to past five years.

A- Projects must be within the past five (5) years to be considered.

A- 60 Mil white PVC is acceptable. Specific manufacturer and product is subject to approval. Follow all manufacturer instructions and recommendations for installation. Do not install roofing system when air temperature is below 40 degrees F, during any form of precipitation, including fog, or when there is ice, frost, moisture, or any other visible dampness on the roof deck.

47. Q. Ref. Drawing Sheet C-102; Regarding site access points and desired travel ways;

Current FOD (Foreign Object Debris) fence and SF (Silt Fence) is shown southwest of the access road between Building 253 and 254. Is it the intent that all project deliveries must enter from the Nemarket St. extension, northwest of Bldg. 256, traveling past Bldg. 256, then left behind Bldg.

254, then right between Bldg’s. 254 and 253 to access the concrete apron (Hangar Door side of Hangar 253? Is this the only allowable access point or can an access entry point be established off of Nashua Ave. to the concrete apron? If there are other routes available, can you define the alternatives?

A- Primary truck access to be off Nashua Ave with a stabilized construction entrance per Detail 1 / C-501, that provides access to the front and rear of BLDG 253. This will avoid construction traffic through the parking lot.

Other alternative access points may be considered subject to the approval of the Base Civil Engineer and Contracting Officer. Submit a traffic routing and site utilization plan for approval by BCE and CO that meets the requirements of Specification Section 311000.1.7 “Site Clearing”, Section 312000.1.8 “Earth Moving”, and any relevant requirements in the General Conditions sections of the Specification.

48. Q. Please reference sheet AE-105 at the intersection of lines 14 and C for Building 253.

The plan shows a CMU wrap around the column at that point. Plan detail 6 on AE-501 shows a metal stud and drywall wrap at that location. Please confirm the intent.

51. Q. Please confirm if the General Contractor must apply for any pay for the Building Permit. Specification section 013000 Part 1.4.A is not clear.

A- A Building Permit (as would commonly be obtained from a municipality for a commercial project) is not applicable to this project as it is a Federal project on Federal property.

As such, there is no fee associated with said permit.

52. Q. Please confirm if there are any fees that the General Contractor is responsible for regarding the permit list in specification section 013000 Part 1.4.C.

A- The Permit for NHDES Alteration of Terrain is attached to the specifications. There typically is no fee for NPDES General Construction Permit (See EPA.Gov website for instructions). There is also typically no fee for the FAA 7460-1 Permit (See FAA.gov/forms for instructions).

53. Q. Sealant joints for the hangar refers to "Section 321372 Concrete Paving Joint Sealants". The spec is not included in the package that I can find.

A- We didn’t find the reference to Section 32 13 72. If it exists, change to read Section 321373 “Concrete Paving Joint Sealants”.

54. Q. Some of the rooms that receive epoxy have carpet and tile on the floors. Cannot see where the demo talks about those materials being removed.

A- Note 5 on AD-104 calls for the removal of carpet, also refer to General note A on

AD-001 "THE ARCHITECT HAS IDENTIFIED, AS COMPLETELY AS POSSIBLE, IN THE

DRAWINGS AND SPECIFICATIONS, EXISTING ITEMS OF EQUIPMENT AND

62. Q. Could you please provide additional information on the 2 existing HEF generators in Hangar 251 that are to be salvaged for Hangar 254? Hangar 251 was not part of the walkthrough. Are the existing HEF generators identical to those in Hangar 254? Is the Hangar 251 system active? Should the supports be salvaged? Are the supports similar to those in the other Hangars? Can they be removed from Hangar 251 when needed or do they need to be removed at a specific time and stored until needed? How high are the Hagar 251 foam generators?

A-The foam generators in Hangar 251 are the same Ansul Jet-X-15A model as those of Hangar 254. Hangar 251 will be converted to a different use under a separate project and the foam system will no longer be required, however it is currently an active hangar. See sequencing requirements listed in Solicitation Section 3.4.2.1.2.e). The supports of the existing foam generators in Hangar 251 are roughly similar to those in Hangar 254. None of the existing supports in any of the hangars are to be salvaged for reuse. Heights of the foam generators in Hangar 251 vary with the roof heights from 20'7" to 38'1". Contractor has the option which two are removed for use in 254. Photos attached.

63. Q. AE-507 detail shows damp proofing section 071113 in the masonry cavity wall.

There is an avb/weather barrier spec 072500 calling out ABAA. Which do you want in the masonry walls?

A- Bituminous damproofing is to be used at masonry locations. AVB/weather barrier is to be used at exterior stud wall locations.

64. Q. Bldg 254 sheet IN-101 Floor striping shows room 40 getting Grey polycrete, sheet AF-601 says room 40 "EXG" which I believe means remains the same. Which is it?

A- Grey Polycrete is specified to match existing floors in the hangar and shops. The floor in Room 40 will be demolished to accommodate new footings per the Structural Drawings, and new floor will need to be finished to match existing. Provide consistent finish throughout the shop.
