Cleaning procedures can be found in section 3.4.2 Cleaning and Coating..

32. Q. On sheet M004 - under "HVAC LOGISTICS NOTES AND REQUIREMENTS", it says in Point 4:

" 4. TEMPORARY CHILLED WATER SERVICE (BY OTHERS) MUST BE SUPPLIED TO CULLUM HALL

WHEN NEW CHILLED WATER SYSTEM WITHIN THE BUILDING IS READY TO BE FILLED AND

TESTED. THE

TEMPORARY CHILLED WATER SERVICE MUST BE MAINTAINED UNTIL THE CENTRAL CHILLER

PLANT (B604) SITE DISTRIBUTION IS EXTENDED TO CULLUM HALL UNDER A SEPARATE PROJECT.

TEMPORARY CHILLED WATER SERVICE MUST INCLUDE (FOR INFORMATION ONLY)."

As per the above statement, we understand that the contractor is not responsible for supplying the temporary chilled water system but he/she is responsible for maintaining it. If out understanding is incorrect, please correct it. Please also provide information if contractor is responsible for fill and test of the new chilled water system. Thanks for your time and advice.

A. The operation and maintenance of the temporary chiller is not the responsibility of the Cullum Hall Construction Contractor.

34. Q. D-120 indicates to "DEMO STAGE FRAMING AND FLOORING. SEE STRUCTURAL AND

MECHANICAL DRAWINGS FOR EXTENTS. SALVAGE FLOORING AND SUBFLOORING FOR

REINSTALLATION". This directive appears to encompass the decorative proscenium arch around the front of the stage. However, the same proscenium profile can be viewed on A-120. Please indicated if the arch is intended to be demolished. And if not, indicate if/how the damage to the arch's decorative plaster and paint is meant to be repaired.

A. No, the "DEMO STAGE FRAMING AND FLOORING" note does not include the decorative proscenium arch around the front of the stage. The full extent of the flooring demolition should be limited to the area identified on AD120.

35. Q. Insulated Floors in the Environmental Rooms: The specification calls for insulated floor panels in the chamber. Drawing A-550 also depicts flooring in the chamber. But it shows a 2" floor in the vestibule into a 4" floor near the low wall shown. Drawing I-502 shows some detail for the recessed concrete for the high density shelving.

Questions:

A. Is only part of the chamber to get an insulated floor? If so, where does the insulated floor end? Please show some details if that is the intent. The Rails for the high density shelving cannot be imbedded in the insulated floor.

B. Would a 2" insulated floor be acceptable for the chamber? A 2" floor would work in a 35F and 35% environment.

C. Can the whole environmental room floor be insulated just as its shown near the high density shelving?

Please clarify and provide additional details of how this should be accomplished.

Answers:

A. The entire floor is insulated. The rails for the high density shelving can be imbedded in the 4" insulated floor. See detail E1/I-502.

B - The temperature and humidity criteria listed in the specification must be maintained. The specifics of the panel thickness, equipment, etc is the responsibility of the environmental room manufacturer.

C- The documents show 4" insulated floor at the main environment room, and 2" insulated floor at the entrance to the vestibule. There is a ramp in the vestibule from the 2" floor thickness to the 4" floor thickness. These thicknesses must be confirmed by the environment room manufacturer.

The environment room configuration (panel thickness, equipment, etc.) are based on discussions with multiple manufacturers and represent a generic approach to room design. At the vestibule the floor is only 2" at the entrance ramp because of space limitations, however since this area is not used for long term material storage this approach was an acceptable solution in this small room. The contractor must confirm the panel thicknesses, design assumptions and necessary equipment to achieve the temperature and humidity criteria listed in the specification for the main environmental room.

36. Q. Due to the lack of overhead space above the environmental room chamber, all of the refrigeration and wiring conduit would have to be mounted to the ceiling of the chamber. Is this going to be acceptable? Please advise.

A. Yes, it is understood that all refrigeration, wiring, devices and lighting will be surface mounted within environmental room. All surface mounted elements should be coordinated with the furniture shown in the interiors drawings.

37. Q. Spec Section 13 21 00 Part 2.3.C says to use fluorescent lighting. Is LED lighting acceptable?

A. Yes, LED lighting is acceptable.

38. Q. Spec for environmental room calls for electrical outlets but none are shown on the drawings. Please confirm no outlets are needed.

A. Electrical convenience outlets should be provided. They should meet the electrical code for number, spacing and installed mounting height. Coordinate the final locations with the environmental room construction and the furniture plans.

39. Q. Spec calls for two different types of humidification and the drawing depict it also. However, at 35F and 35% no additive humidity is required. Please advise why humidifiers are specified..

A. The humidifiers listed in specification section 13 21 00 (by the manufacturer) can be omitted. The HVAC system delivering ventilation air to cold storage is equipped with both a humidifier and de-humidifier.

40. Q. In Spec Section 13 21 00 Part 2.3.F, 3 options of floor covering are listed. Also, drawing I-100.B1 & I- 502 shows epoxy flooring being installed. Please clarify what flooring finish is required? Is the environmental room manufacturer required to install this flooring?

A. Finish flooring contractor should install the epoxy flooring in the environmental room per the specified flooring noted on the Finish Schedule or equivalent. Contractor to coordinate work with installation of motorized High Density Storage with recessed rails.

41. Q. Ballroom elevations on sheet A-418 reference keynote 5: "repaint element to match the original faux-scagliola finish." Please provide an image of what the original faux scagliola finish is to be matched. Alternatively, allow submittal of samples of best practice scagliola consistent with the original intent.

A. The intent for the painted faux-scagliola is to match the real scagliola on the caryatid bases at the south entrance to the ballroom. Finish Schedule under Finish Code (XW6) identifies the locations of that finish work on the Interior Finish Location plan Sheet I-102.

42. Q. Ballroom elevation A1 on sheet A-417 indicates "patch scagliola." However, in the same areas, keynote 6 denotes "replace incompatible patches in marble with new material to match surrounding." Please confirm if this material is marble or scagliola.

A. The material of the caryatid bases at the south end of the Ballroom is scagliola, not marble.

43. Q. Please confirm all metal plaques and cannons are to be protected in place; no bronze cleaning or refinishing of anything outside of the vestibule.

A. Confirmed. With the exception of the bronze in the vestibule, no cleaning or refinishing of the bronze plaques or cannon throughout the building is in scope. However, any dust or construction debris that may accumulate on these materials during the course of the work must be removed.

44. Q. Can the East side Restoration work (Granite Cornice /Chimneys) be access from the road below with a manlift? If so does that road have to remain open to traffic? Can the Terrace/Brick Paver walkway support a manlift/scaffolding to access cornice work around the perimeter of the building.

A. It is the contractor's responsibility to determine the means and methods to perform the work and its impact on the existing structure. However, it is possible to access the east cornice & chimneys with a lift from the road. The contractor must confirm/coordinate with the USACE contracting officer any isolated temporary road closures on the East side of Cullum.

45. Q. Plans indicate an off-sized catch basin of 32"x46". Please clarify if 30"x48" standard size pre-cast catch basins can be utilized.

A. A 30" x 48" standard size pre-cast catch basin is acceptable provided the structure can accommodate the required curb piece.

46. Q. Drawing P-10B3 Top right corner between columns EW1 – EW2 indicates 5" RWC above floor is dead ended by the 5" tee picking up 5" copper Riser to above floor. Does this pipe tie into the 6" RWC that is runs along the hallway ceiling? Please advise

A. A 2" vent shall be run from Sewage Ejector pump and pit at Level B3 and shall tie into the building vent system. This vent pipe will be added to plan and diagram.

47. Q. I-100.B1 shows flooring EF1 in room CH-B108. EF1 is not defined on the flooring page of the finish schedule (I-001). Please provide a definition for EF-1. Additionally, this is the only finish provided for room CH-B108. Please provide completed finish schedule for this room.

A. Epoxy Flooring has been changed to EF4. (Epoxy floor finish EF1 is defined on the Finish Schedule I-001 for Bid - Add Alternate #4 below the General Notes).
