Demolition/Construction/Cleanup must be conducted outside of Mammography s Hours of Operation: Mon-Fri, 8:00AM-3:30PM.

Sanitary piping demolition and new work above 1st floor Emergency Department ceilings

Definitely highest risk for the 5-bay patient room, adjacent spaces, and their Clean Storage room. Work in the ED ceilings may only be done on weekend nights (Friday, Saturday, Sunday nights beginning after 10pm). We expect Control Cube required in the 5-bay patient room and Clean Storage. Note that what is shown on the plans as a male bathroom next to the Break Room is actually the ED Clean Storage room.

Data cabling above 1st floor Emergency Department ceilings

Related to response on 1st bullet, correcting the route for cabling. On 1st floor, work would be exclusively conducted in the 1st floor D-wing TIPS closet, including the termination of cabling. The cabling can utilize the existing risers, leading to the 2nd floor s D227. There are no time restrictions, but expect to provide and work in an isolation cube(s) & temporarily cease work, to allow staff admittance to the respective room that s blocked.

2" Topping slab demolition throughout work area (AD-100 boxed note indicates off-hours may be required but not clear)

Subfloor topping demolition may only occur on a Saturday during the day, with coordination with the ED department. (This will be heavily disruptive to the ED, but better than disturbing sleep in the ICU and CLCs.)

Is Nurse Call required in the project?

No new installation of Nurse Call work is included in this project.

Does all nurse call removal require complete pipe removals back to source, or can wires be pulled out and conduits left in ceiling?

Remove existing wires back to source. Remove drop conduit back to ceiling. Existing raceways in ceiling may remain (note that many Nurse Call wires in the hospital are routed in shared cable trays that contain cables from other communications systems, which are scheduled to remain).

Will data removal require cables to be removed back to rack, or can some be re-routed, and re-used? Is there enough room in the existing floor sleeves and data rack to accommodate the additional cables, or will additional components be required?

Contractor may reuse any existing data cables that conform to specifications and applicable codes as if new. Existing floor sleeves and data racks have sufficient capacity to accommodate new cables.

GI-003 Construction Phasing Plan indicates Phase 1 is 10 weeks for asbestos testing and abatement. Please provide asbestos survey if available.

Asbestos testing has already been completed. No location in the project area was found to be hot and no abatement work is included in this project. Asbestos survey is attached with RFI response. Phase 1 work is excluded from the project and project schedule should be reduced by 10 weeks.

Section 130541 SEISMIC RESTRAINTS lists partitions, mechanical ductwork and piping, electrical/telecom conduit and cable tray, ACT ceilings and light fixtures, and casework. Will all of these components listed in the spec require seismic bracing? Only indication in plans is a reference on MH-101 to detail 11/MH-701 for seismic bracing of reheat coils.
