This room is for personnel work spaces and for developing patient treatment plans. Treatment A-338 A new Approx. 165 square foot Treatment Room with exam/treatment table, medical gas and oxygen, new hand wash sink and support storage and provider wall mounted work station for minor procedures. Structural: The existing concrete vault must be expanded in width to accommodate the proposed new Elekta Versa HD equipment.  The footprint of the vault will be expanded to the East, into the 1976 Ambulance Garage addition.  The existing vault Eastern wall and 1976 Ambulance Addition wall will be removed at the interface location. The existing reinforced concrete waffle slab roof framing of the 1976 Ambulance Garage addition will be cut back for the expanded vault.  An approximately 400 square foot x 2 -0 thick extension to the existing vault mat floor slab will be constructed to support the new reinforced concrete vault wall and vault door. The room is shielded with standard weight concrete in addition to lead shielding as indicated within the documents. Structural support of the lead shielding is required. The existing vault roof slab is a two-way slab, which is supported by the existing four perimeter vault walls. Since the Eastern wall of the existing vault is to be removed, a new steel support beam will be installed to support the edge of the existing vault roof slab. The beam will be supported by the reinforced concrete vault walls. A new, approximately 4 -3 thick, reinforced concrete roof slab will be constructed to extend the width of the vault. New reinforced concrete walls will also be constructed to expand the vault. The new roof slab will be supported by the new steel beam and the new reinforced concrete vault walls. The existing 1976 Ambulance Garage addition roof will also be supported from the new vault walls. The proposed Elekta Versa HD equipment requires a different pit than the existing equipment. The existing pit and associated trenches will be in-filled. A section of the existing vault floor slab will be removed, so a new pit can be poured for the new Elekta equipment. New shielding concrete will be poured on the roof of the existing vault, as per the requirements of the physicist s report. Two new duct openings will be cut through the waffle slab roof of the 1976 Ambulance garage addition. Various Elekta equipment, such as lasers and monitors, will be mounted to the vault walls and ceiling Mechanical: Existing Air Handler The current HVAC system consists of an outdoor central station air handler located on the roof above room A-324. The unit is ducted to serve all spaces of the current X-Ray suites and the LINAC room with the exception of the general offices which are served by as standalone 3-ton ducted split system. There are multiple hydronic and electric reheat coils used to provide area zoning with ceiling diffusers and sidewall grilles to provide distribution of air throughout the suite. The existing air handler shall remain to serve the existing LINAC not being renovated, the exam and waiting areas. Heating System The heating system is served by a medium pressure steam service. The air handler utilizes the steam for a preheat steam coil and zone humidification. Steam is also used for a steam to hydronic heat exchanger used to serve the reheat coils. Refer to the construction documents to determine which portions of the heating system are to remain vs. which portions are being demo d and or replaced. Cooling Supply The existing air handler is served by a 36 Ton Daikin condensing/compressing unit. This unit provide two refrigerant line sets to a split DX coil in the central station air handler. The existing 36 Ton condensing/compressing unit shall remain to serve the existing LINAC not being renovated, the exam and waiting areas. New Air Handler A new HVAC system consists of an outdoor central station air handler with split system DX cooling shall be provided to serve the new LINAC room, Equipment room Control Area, Dosimetry and the Physicist storage room. The new air handler will be roof mounted above the renovated LINAC room. The new compressor/condensing unit will be ground mounted adjacent to the existing 36 ton unit. Hydronic reheat coils shall be used to regulate space temperature. New Secondary (Redundant) HVAC System for the LINAC Space The new redundant HVAC system will be a ductless split system serving the LINAC room, adjacent equipment room and the control area. The LINAC will have two recessed ceiling cassette units. The Control area will have two recessed ceiling cassette units. The equipment room will be served by two wall mounted units. The new central station air handler is still the primary HVAC source serving these areas. The ductless split system is a redundant system to ensure functionality of the LINAC if the central station air handler fails or requires service. Air Distribution The existing ductwork and reheat coils in the ambulance bay office areas and LINAC being renovated shall be removed and replaced with new. All other ductwork and reheat coils shall be altered as appropriate to continue to serve the existing spaces to remain. Plumbing: The project scope for plumbing is limited to replacement/addition of four sinks in the area of renovation. The sinks will be stainless steel with chrome plated brass fixtures. Relocation of existing sanitary lines and extension of domestic water and vent lines will occur. The existing Air, Oxygen and Vaccum lines and outlets serving the LINAC shall be replaced with new. Fire Protection: The existing space is fully sprinklered. The renovation of the space will require sprinkler branch piping to be demoed and new piping to be installed with a new quick response sprinkler head layout to meet NFPA 13 guidelines and in accordance with the construction documents. Electrical: The existing LINAC is currently being powered from a bus tap off Sub CN with a 100AF/100AT disconnect switch. The majority of the mechanical equipment and general power needs for the area are connected to power panel PP-LA. The proposed LINAC power load is very similar to the existing LINAC (45 kVA) and requires the same overcurrent protection. The ability to power the new equipment from the same location as the old and keep the power consumption the same is advantageous from a shutdown/disturbance standpoint. There is sufficient panel space from PP-LA and the relocated panels to power the ancillary equipment and new office space. Receptacle spacing and location will be per LINAC installation guidelines and VA Design Manual recommendations. The existing electrical closet will be relocated to accommodate the new floor plan. The power panels will serve the LINAC and adjacent office area. Each desk area will be incorporated with a quad receptacle and four data ports. The power for LINAC will reflect the drawings from Elekta and the requirements from the VA team including monitors, desk areas, etc. The lighting for the space will be LED with energy saving lighting controls. Vacancy sensors will be placed in each space with daylight harvesting where applicable. The lights will be fully dimmable. No color tuning or warm to dim options are anticipated for the project. LED decorative panels will be installed in the LINAC space for patient comfort. See attached cutsheets. Asbestos Abatement: This project requires abatement of approximately 25 square feet of floor tile and mastic in room A-334 and 160 square feet of exterior HVAC duct insulation and waterproofing at the LINAC roof level directly above the LINAC. 5.
