RFI 0002: Specification Section 028220 paragraph 1.03D states, “This specification is based on an Asbestos Survey of the site conducted by AECOM in October 2015. Laboratory test results are on file and may be obtained for review and are attached to this specification.”

The referenced Asbestos Survey conducted by AECOM does not appear to be included with any of the RFP documents. Please provide this survey.

Answer: The Asbestos and Lead survey is attached: Titled: W91364185000 Hangar 885 Survey Reports and Sampling Data.

RFI 0003: Section 010000 paragraph 17.11 describes the requirement to have all employees complete the AT Level I Awareness Training. The website link in paragraph 17.12.1 does not work. How long does this training take and are there any costs associated with the training?

Answer: The correct URL for AT Level I Training is: http://jko.jten.mil/courses/atl1/launch.html it is an on-line course. There is no cost associated with taking the course.

RFI 0004: Specification Section 028220 paragraph 1.05 says, “The total quantity of ACM and/or contaminated materials shall be field verified by the Asbestos Removal Contractor during the Pre-bid walkthrough. If the Asbestos Removal Contractor finds any perceived conflict, error, omission, or discrepancy in the Contract Documents, the Asbestos Removal Contractor shall submit a written request for an interpretation or clarification prior to the Bid Opening as specified in Division One of the Contract Documents. The Asbestos Removal Contractor shall not, at any time after the Bid Opening, be compensated for a claim alleging insufficient data, incomplete Contract Documents, or incorrectly-assumed conditions regarding the amount or nature of Work, if no request for interpretation was made by the Asbestos Removal Contractor prior to the Bid Opening. “

It is an impossibility of performance to expect us to catch any errors in the government provided design / scope of the hazardous material abatement work by making a short visual inspection during the site visit to the facility. In addition we cannot tell by a visual inspection if a building material is hazardous or not.

That determination can only be made after destructive field sampling and laboratory testing. Even if we could make a determination of whether a building material was hazardous by looking at it, there may still be hazardous materials hidden above ceilings, behind walls, underground, etc.

Please remove the paragraph noted above from the contract documents and confirm that bidding contractors should assume the only hazardous material that we are to include in our bid is the hazardous material specifically noted to be removed and that any additional hazardous material that may be discovered after award will be treated as a differing site condition.

Answer: The Hazardous Material and Environmental Survey was issued as a response to RFI-0002

Revise Specification Section 028220 paragraph 1.05 to read as follows: "The Hazardous Material and Environmental Survey indicates all areas in the building where suspected asbestos containing materials (ACM) were tested. Therefore, all impacted ACM within the renovation or demolition area should be http://jko.jten.mil/courses/atl1/launch.html removed and disposed of in accordance with Federal, State, and local regulations, prior to disturbance.

ACM not impacted within the renovation or demolition do not require removal as a part of this project.

ACM that are discovered during construction and required removal but are not indicated in the construction documents, specifications or noted in the Hazardous Material and Environmental Survey that was issued as a response to RFI-0002, will be treated as a differing site condition."

RFI 005- Please provide As-Built drawings for existing building.

Answer: The hanger underwent a large scale renovation in 1981. Those drawings are included which show how the additions were constructed.

These drawings do not show the thickness of the existing concrete floors in the building. The concrete floor thickness throughout the building is 14 inches thick.

Following drawings/documents are attached:

RFI 012: Note 1 on sheet S101 says the existing floor construction, unless noted otherwise, consists of a 10" thick concrete slab on grade. In the Government's response to previous RFI 005, it was stated the concrete floor thickness throughout the building is 14" thick. Please confirm the thickness of the existing concrete slab on grade for bidding purposes.

Answer: Previous saw cutting has indicated that the thickness of the concrete can vary from 10" to 14".

There are no records of where the concrete thickness changes. For planning purposes, plan on having to saw cut and demo concrete that is 14" thick

RFI 013: Section 016000, Product Requirements; Section 012500, Substitution Procedures

The restrictive procedures for product selection and substitutions in the referenced sections will unnecessarily and significantly restrict competition and will increase the cost of the project to the Ohio National Guard. We suggest and request that these sections be eliminated and adopt standard “Or Equal” provisions for all products be added to the RFP.

Answer: Delete Sections 016000 and 012500 from the specifications. Contractor may provide products that are "Equals" to the basis of design product listed in the individual specifications. Equal products must meet or exceed the specifications listed. The products/materials will be approved/disapproved during the submittal process by the Contracting Officer at the advice of the Contracting Officer Representative (COR) once the construction contract has been awarded.

The only sole source items are: Monaco Fire Suppression System and Project Mates Software (Justifications and Approvals are provided on FBO).

RFI 014: The drawings on sheet A601 show the sign types and there is no mention of frames needed for these signs. In the specs on page 3 of section 101423.13 mentions that frames are needed for signs.

Is the Quality Control Manager required to have a current USACE CQM Training Certificate?

Is there any specific training, experience, or other requirements for the Project Superintendent and Quality Control Manger?

Answer: Correct. As stated in section 014000-1.06.B the project superintendent may serve as the quality control manager. This project is not a USACE project. No USACE training certificates are required for individuals nor are there any other training or experience requirements for the project superintendent or the QCM.

RFI 023: Specification 081113 Hollow Metal Doors and Frames, paragraph 1.03.B says, “Blast Resistant Door Assembly: An assembly of hollow metal door, steel frame and finish hardware, tested and approved as an assembly of components, capable of meeting ASTM F2927 and UFC 01-010.01 performance criteria for a 55 psf, 3 second force and achieve Damage Level Category II or better.

This information is an ASTM F2248 3 second duration design load. ASTM F2248 is used to calculate an equivalent 3-second duration equivalent design load to design blast glazing used in windows and vision lights only. It is not applicable to doors. A charge weight and standoff distance is required to determine the design blast load for the door.

In order to price blast doors, we need a charge weight, standoff distance, and level of protection. A damage category of II, as stated in the RFP, is a medium level of protection. The vast majority of UFC projects are for a low level of protection / damage category III.

There appears to be no indication as to which doors will require a UFC blast door. Please clarify which doors need to comply with the UFC requirements for blast resistant door assemblies and provide the charge weight, standoff distance, and level of protection for each individual blast door.
