Response: There is not a single list, the owner-furnished equipment is identified throughout the Contract Documents.

37. Question: In closet 123 is a wall mount rack being installed?

a. If so, what size and;

Response: Yes, a wall mounted rack shall be provided per drawings to house SEIMONS or equivalent patch panels. The rack shall be sized to have a minimum of two 48 port patch panels. The patch panels provided shall only encompass 60% of the cabinet area.

b. does it require a fan.

Response: No fan is required for the wall mounted rack.

38. Question: In room 141, I see a floor mount cabinet is required. Is there a standard you use or is at our discretion to pick and send cut sheets for approval.

Response: The floor mounted cabinets shall be provided per drawings to house SEIMONS or approved equivalent patch panels. The cabinet shall be lockable, have a minimum of 60% of the cabinet area filled with patch panels. Yes, the proposed cabinet type shall be submitted for approval.

39. Question: I have looked through the specification manual and do not see an installation or equipment section. I have noticed on the prints that the cable tray and wire has been addressed as to type and manufacture, but as for patch panels, data/phone jacks, vertical/horizontal managers, wall plates, fiber optic connectors, fiber optic enclosures and labeling schemes, I have not seen these items. Is the termination of cabling the responsibility of the contractor or is the communication division of your base accomplishing this task? If it is the responsibility of the contractor, is the above equipment being supplied by the owner?

Response: The termination of the cabling is the responsibility of the contractor. The above listed equipment shall be provided by the contractor per drawings and specifications.

40. Question: Please provide a building number that all Fiber and phone backbone originate from. This information is crucial for determining length to new locations

Response: See sheet E005. The comm. Building is indicated as BLDG 116.

41. Question: According to the keynotes on the technology prints, it states that all data/phone wiring needs to be in continuous conduit or cable tray. Is this a true requirement? If so, then am I aloud to run conduit from outlet box to cable tray then route cable to IT closet. The reason I pose this question is due to the lack of a specification manual.

Response: Yes and yes

42. Question: Would it not be advantageous to run cable tray in hallway 130 of Reserve Center? It would save on conduit expense and labor.

Response: Maintain cable tray routing as indicated on drawings.

43. Question: The Joists on the Framing Plans are all called out as standard S.J.I Joist sizes but noted as "SP1 or SP2". When referring to the Joist Schedule on Design Drawing A-S600-0, there is a Roof Joist Schedule showing the loads these joists are to be design for. Looking at the schedule, there appears to be substantial snow/live loadings applied to some of these joists. My question is: Should all of these loads be considered simultaneously on the joists or shall there be certain load cases considered? Looking at the S.J.I load tables for the 40LH14 joists, the loading of the 40LH14 at approximately 69'-0" in length would cover the W1-Dead Load, W1-Live Load, & W1-Snow Load. On the other hand the allowable loadings of the 30K11 & 20K6 joists from the S.J.I Load tables are exceeded by the W1-Dead Load, W1-Live Load, & W1-Snow Load.

Response: Live load and snow load do not need to be considered simultaneously. Total load should include Dead load + (worst of LL or Snow Load). For determination of deflection, use worst of Live load or Snow load.

44. Question: Have Power and Gas services been engineered and fees estimated by the utility providers, and are these fees by owner?

Response: Power services have not yet been engineered or fees estimated by the utility provider. Per drawing E002-0 Power and Lighting Site Plan, Keyed Note 2: "CONTRACTOR SHALL CONTRACT WITH OHIO EDISON TO RELOCATE POWER POLE AND ALL ASSOCIATED WORK TO MAKE AERIAL PRIMARY FULLY FUNCTIONAL." The cost shall be contractors responsibility. Gas services design is complete and a contract pending to bring the supply to the site. Connection fee shall be contractor responsibility.

45. Question: Detail "D" and "E" on A-S501: How are they used together or separate?

Response: Detail D/ A-S501 applies between joist bearing locations at concrete walls. Detail E/ A-S501 applies at joist bearing locations at concrete walls.

46. Question: When does Detail "E" on A-S301 appear on A-S100? It appears to be miss-marked.

Response: Detail E/A-S301 is referenced on A-S101.

47. Question: Where is structural sheet S500 the drawings refer to?

Response: Sheet S500 is before sheet A-S100 in the set.
