CONSOLIDATED RFI RESPONSES

SOLICITATION W912JD-10-R-0001

Replace KC-135 Maintenance Hangar

RFI 0003:

Questions: We are not able to find any specification for the interior fall protection over the KC-135. Please provide information for the interior fall protection that stipulates the design requirements (e.g. designed by a professional engineer, number of users for each system, number and type of harnesses, self retracting lifelines, fall arrest trolleys to be supplied, etc.)

Answer: Specification for fall protection will be issued by amendment.

RFI 0004:

Questions:

1. Drawings call for an epoxy floor in the hangar area, however, no specification for epoxy flooring can be found in the documents. Please advise.

2. Site drawings show removal of underground utilities (i.e. 1-1/2" water line, sanitary sewers, storm sewers, and electrical conduit lines). Are these to be abandoned in place or do they all have to be removed?

3. The size of the foundation and thickness of the slab for the existing hangar to be demolished are not shown on the drawings. Please advise.

Answers:

1. Per request of the 101st Maintenance Squadron, the hangar floor originally scheduled to receive reflective dry-shake surface hardener will now receive a three-coat system epoxy system. The first coat will consist of an epoxy primer coat and moisture vapor block, if required. The second coat will be an epoxy body coat with broadcast application of non-skid white aluminum oxide abrasive. The third coat will be a urethane topcoat. Color shall be ultra light gray. The specification for this system will be issued by amendment.

2. All utilities shown shall be capped and removed from the site. Remove as indicated on the demolition drawings.

3. See additional reference drawings issued under Amendment 0002.

RFI 0007:

1. Specification section 32 13 00-Portland Cement Concrete Pavement for Airfields notes that either a slip-form process or a side-form process may be used for the installation of this concrete material.

Specification section 32 13 00 - 3.10.C goes on to state that if the side form process is used, the finishing screed machine must move forward with a combined longitudinal and transverse shearing motion. Speaking with several screed machine manufacturers, we cannot find a form riding machine that does this. Is it the intent of the specification to preclude the use of the side-form process for concrete pavement? Will a standard triple roller screed be allowed for this work?

2. Plan sheets A-111, S-004 and S-400 show a set of fall protection tie-off beams above the aircraft parking location inside the hangar. The structural drawings indicate that the design of the rails and support system are to be by the Fall Protection Supplier. The only project specification for fall protection is 11 10 16 - ROOFTOP FALL RESTRAINT SYSTEM. This section does not address the fall protection items inside the building. Please provide guidance as to the intent and design of this interior system so that we can find appropriate suppliers for it.

1. A standard slip-form or side-form process is acceptable.

2. Specification for fall protection will be issued by amendment.

RFI 0010:

1. Section 313116 calls for Termite Control, will this be required for the project?

3. Section 321215, Page 3, requires a MTV for asphalt paving. Since the paving is in tight areas and not on taxiways or runways will this be required?

4. Section 321215, Page 16, requests that a test strip be performed for hot mix asphalt paving. Where the area of paving consists of tight areas, will a test strip be required?

5. What permits will the contractor be required to obtain for the project?

6. What is the extent of the demolition for building 499 that will be performed by the contractor?

7. Is there information on the foundation of building 499 that could be provided showing the depth and size of the foundation walls and footers that are to be demolished?

8. Drawing C-302 detail 8 & 9 both refer to detail 15/C-302 which is left blank on the drawings. Could you provide detail 15/C-302?

1. Termite Control is required.

2. Capillary Water Barrier is REQUIRED per S-001, section 4.

3. Will be removed.

4. Test strip is not required.

5. Civil permits would include such items as FAA, EPA Construction General Permit, and SWPPP.

The contractor is responsible to adhere and obtain all required permits. This list may not be all inclusive. The Contractor is required validate all permits that will be required.

6. As indicated on the bid documents. See additional reference drawings issued under Amendment 0002.

7. Additional “For Information Only” drawings will be issued by amendment.
