5. Attachment #23 is a CAD file containing Contours and Utility lines only. There are not any references to existing building, streets, sidewalks, or other built elements that would allow us to locate the building on the site. Do you have any existing AutoCad Drawing Files (.dwg) of the existing site plan that shows the buildings as well as other built elements within the location of the sample project? - See attached CAD files.

6. Do you have any existing AutoCad Drawing Files (.dwg) of the existing Building including Architectural and Engineering Drawings? There appears to have been an addition to the building after it was originally constructed. It appears as though these files were completed in AutoCad format. – See attached CAD files.

7. -Is the existing Communication Line depicted on plans in a duct bank? – Use comm. from existing service in the building mech room on addition side, see attached drawing.

8. -Location of existing electrical service location (which room, where in the room)? – Assume the main transformer and service to the existing building is adequate to handle the additions loads. Contractor shall tap ahead of the main, install disconnecting means and feed new addition. See new drawing for additional electrical information.

9. -From where does the electrical service come (transformer location)? – Assume the main transformer and service to the existing building is adequate to handle the additions loads. Contractor shall tap ahead of the main, install disconnecting means and feed new addition. See new drawing for additional electrical information.

Contractor shall tap ahead of the main, install disconnecting means and feed new addition. See new drawing for additional electrical information.

15. The survey pdf issued with Amendment 5 shows a gas line in the legend but it doesn't appear to be located on the drawing. The response to RFI#11 in the Technical questions (also from Amendment 5) refers to the revised solicitation for the answer to whether natural gas service is available at the site. We do not find any reference in the revised SOW or the solicitation for natural gas. Please confirm whether natural gas is available on the site. – No gas line is in the area.

21. Per attachment 11, proposal submission requirements – ‘bound drawings 1 set (11”x17”)’. Please clarify the size required for drawings. Per the Shaw AFB Installation Development and Design Handbook (ID2) drawing borders shall be 24” x 36” (page B-22), therefore when printed to 11x17 as the submission requires, these would not be to scale.

27. Per SOW dated 29 AUG 2013, page 5 of 7, 35% Submittal requirements includes the statement “Contractor shall submit, at this time, color samples for all exterior colors in hard copy format”.

32. Having received Amendment #5 and having viewed the site/facility on September 10, there remains much ambiguity regarding the existing electrical service(s) to the building. The original 1955 electrical riser diagram seems to indicate a 300A, 208Y/120V service to the building. The “chapel number one addition” electrical riser diagram shows what appears to be a weatherhead and vertical conduit dashed, with a new weatherhead and 225A service to an enclosed breaker, then on to panels M and A. It is unclear if this indicates there are two electrical services to the building, or if there is just one. If there is just one, how are they interconnected, and what is the ampacity of the service?

If we are to relocate them as part of the project, what is the size of the ductbank, and where are the nearest manholes to either side of the site, to determine the amount of cable which will need to be repulled? –Assume this ductbank has been relocated outside of this general area.

35. Design/Build Statement of Work, Page 4 of 7: The fire alarm paragraph does not mention mass notification. Please confirm that a mass notification system is not required for this building. – No mass notification is required.

Please provide the referenced drawings per the statement in Amendment 005 – See revised SOW.

37. Are hard copy material sample required for all exterior finishes, materials and construction details? If each Contractor submits color samples for all exterior colors in hard copy format, there would be a burden on the contractor and the reviewers. – Normally, actual physical samples are required, however for the purpose of this sample project, photographs may be used instead of actual samples.
