Hard wired electronic faucets shall be disconnected, wire removed to the active j-box above ceiling and a blank brushed stainless-steel cover-plate installed over the vacant box below the sink; In-wall conduit and box can remain.

16. Waste / Disposal: Disposal shall include all associated costs, such as handling, packaging, wrapping, container costs, and any offsite costs, such as transportation and disposal/dumping fees. The contractor is responsible for any byproducts of their construction (such as dust, runoff, leaks, stains, fumes, rubbish, waste) and any associated impact or costs. Once items/materials are removed/demolished, they are the contractor’s property and responsibility (unless noted otherwise).

17. Patch-Back & Restoration of Finishes: Patch back as necessary using materials to match the adjacent construction and finishes. When sink/lavatory or piping stub-outs are removed, patch holes and skim wall to level 3. Spot painting (touch-up) is not permitted. Electronically match existing paint and roll (prime and 2 base coats) from corner to corner. On walls with vinyl wallcovering, fill any wall screw holes with silicone. Match or complement wall color. Sealant and color selection shall be equal to Dow Corning 795 Silicone and 14 color selection charts. Coordinate color selections with COR prior to installation.

18. Normal Hours & After-hours Work and Work Productivity: Normal duty hours will be 7:00 am - 4:00 pm

Monday through Friday. No work shall be performed on federal holidays unless approved by COR. This project will require work to be performed outside of normal duty hours (after-hours) to minimize the impact on patients and Medical Center operations and must be coordinated with and approved by COR two (2) weeks in advance. Installation of fixtures in clinics, exam, treatment, emergency department, surgical areas, and PACU shall be performed after-hours. Installation of fixtures in wards, office and support areas can be performed during the normal duty hours, but progress will be slower. Shutdowns of mains or risers shall be performed after-hours. Based on previous fixture replacement projects during normal operational hours, 2 plumbers (2 crews) completed approximately 4 faucets and 1 shower per workday. Daytime plans were routinely altered due to room utilization and plumbers had to remain flexible, working with the COR to find available rooms each day. For fixture swap-outs, the facility will only be able to accommodate 2 plumbers (2 crews) during normal working hours and 3 crews after-hours. Contractor expectations for productivity/progress during normal working hours should be based on this real-world performance observed on the previous projects. Multiple shifts per day is not authorized for this project.

19. Shutdowns: Shutdowns of main lines and risers must be requested 3 weeks in advance (and performed after-hours). When draining the entire system, in addition to the time required for the installation (such as riser valves and/or injection ports), the contractor’s crew(s) shall be present while the system is drained (typically 2-3 hours) and refilled (typically 3-5 hours) with the contractor checking for leaks.

20. No Smoking: This is a smoke free facility. Contractor shall enforce the no smoking policy with his project staff. Smoking is not allowed on VA property, buildings, vehicles or grounds.

21. Identify Locations: To identify the location of a new valve or valve assembly (including biocide injection port assemblies), apply a blue-colored dot (1/4” or 3/8” water and UV resistant vinyl sticker) to the grid.

22. Final Inspection: 2 weeks in advance, request final inspection in writing to the CO and COR.

23. Warranty: All work shall be warranted for one (1) year.
