30. Reference the Building 65 workroom (Room 302), drawings A3.62 and A6.60: A3.62 shows a solid surface countertop with a 4” backsplash and a plastic laminate back splash up to the underside of the upper cabinets. Sheet A6.60, sections 3 & 1, do not show any backsplash. Sections 4 & 5 on this sheet DO show a backsplash. Please clarify.

BRS: Details 1, 3, 4 & 5 DO show a backsplash with a note that says RE: Interior Elevations for materials.

For clarity, Building 65 and the Auto Shop have a 4” backsplash that matches the countertop while Building 49 has a tile backsplash that goes the underside of the upper cabinets. Please refer to A2.61, A3.62, A3.64, A3.65, A4.62 for materials.

31. Although all of the drop points are clearly identified as to the quantity of cables to each, my question is: are all of the cables to be just data connections or, is there at least one of the cables, except for the WAP’s, designated as a voice connection? Please verify.

AE DESIGN: Provide cables for all data connections.

32. Should one of the cables at each outlet be designated as a voice connection, would the following cable color coding be acceptable:

- Category-6, plenum, blue for data,

- Category-6, plenum, white for voice,

- Category-6, plenum, yellow for WAP.

- If decided to not be acceptable, please provide the require cable color coding.

AE DESIGN: See above. Blue for data is acceptable for all network drops other than WAPs. Yellow is acceptable for WAPs.

33. What type of telephone system is to be installed: Digital or VoIP? If digital, are the station cables to be terminated on 110 Category-6 mounting blocks? If VoIP, all cables can be mounted to Category-6 patch panels. Please verify.

35. The specifications refer to surge protected power units in section 27 13 23. However, Section 27 13 23 is titled “Communications Optical Fiber Backbone Cabling” and does not include any requirements for power strips. The specifications mention power strips in Section 27 11 00 (2.2)(F) and the requirements to meet. However, Drawing E7.2, Data Equipment List ‘R6’ describes a different power strip to be installed. Please clarify.
