The access floor in CR 2B is a wood core floor and the understructure does not have fillet welded pedestal heads required to meet the 2,500 Lb. load requirements. The access floor is a wood core panel and the understructure are not compatible with the Tate ConCore floor system. Please confirm that new understructure and stringers will be required | The existing pedestals utilize a screw connection flat top plate to receive the stringers, which meets the Concore 2500 requirements. See the attached engineering study that recommends reusign the existing pedestals nd stringers in CR2B. | |

| 2 | 13 | PWS 6.3.1 | 4 | PWS 6.3.1 | The existing SRG is supposed to be a bare copper 2’x2’ grounding grid. Per Appendix C the ground SRG ground conductors are to connect to a 4/0 perimeter grounding loop. Based on our site visit, the SRG conductors are NOT 2’x2’ but 4’x4’. No perimeter ground loop was located. | The SRG as installed is on a 4'x4" grid that shall remain. PWS Section 6.3.1 should have stated 4' x 4' grounding grid. Disregard Appendix C required 4/0 perimeter loop. The existing 2/0 perimeter ground loop shall remain as shown on Electrical Drawings E-109 through E-112. | |
| PWS changed to reflect the existing SRG per Appendix I. The existing SRG is a 4 x 4 grid with a 2/0 perimeter grounding loop. | |||||||

Will there be a final ISO 14644-8 deep cleaning for the above floor and raised surface? | If a new raised floor is provided clean then made dirty by the contractor's efforts by project end, then yes the raised floor would need to be deep cleaned. | ||
| 2 | Appendix B 3.4 | 4 | Appendix B 3.4 Cleaning and Protection | For the resealing of the subfloor surface, is it for just the areas that have been patched or is it for all the areas that have not been sealed? | All areas that have not been sealed. | ||
| 2 | PWS Section 6.2 | 4 | PWS Section 6.2 | Will any cutting of floor panels be allowed in and around the dock area? If not, is there a distance away from the building that must be maintained for this process? | Cutting is allowed on outside dock and adjacent to the facility next to the dock. | ||
| 2 | PWS Section 6.2 | 4 | PWS Section 6.2 | Do the ramps in Room CR2B need to be replaced to support the same load as the new access floor panels? | Yes, the existing ramps must meet the same load characteristics as the raised floor.

| 2 | PWS Section 6.2 | 4 | PWS Section 6.2 | The specification calls for 1/8" think HPL…Is 1/16" HPL Nevamar Gray Starlite acceptable for the access floor panel finish if we can't get the 1/8" HPL? | If it is proven that 1/8" HPL cannot be obtained, then the COR may approve a substitution during the material order process. | The PWS has been revised to permit the use of 1/16" standard HPL. | |
| 2 | General RFP | 4 | General RFP Comment | Recommendation for addition to RFP. Based on experience, we recommend the awarded contractor test the ground system prior to starting the disconnect of the system. This step is performed to ensure the grounding is working properly prior to the contractor touching the system. | The requirement is to provide the Government a working system as specified in the RFP at the end of the project, thus if the contractor wants to test the system prior to removal, they are allowed to. |
