This effort will include the removal of the slab in and around the existing pit, a southwest corner of the vault slab, and a linear trench from outside the vault wall diagonally up to the new Equipment Room approximately 26 feet. The next aspect to the demolition is to remove walls and ceilings as identified within the demolition documents as well as remove and store existing items which will be relocated back into the suite. Plumbing elements, see narrative and drawings for extent of demolition Electrical elements (wiring, panels, transformers, switch panels, lighting, outlets, etc.) see electrical narrative and drawings for extent of demolition. Mechanical units and ductwork necessary to make the building service in its new function, see mechanical narrative and drawings for extent of demolition Renovation Work The bulk of the renovation is to prep the vault to receive the MRI-Linac unit by introducing a new pit, installing RF copper shielding on all vault surfaces, Unistrut system, HVAC and electrical connections, cable trays, fire sprinkler system, lighting, conduit connections to the Equipment Room, and final finishes. Of note, given the sensitive nature of the MRI-Linac requirements all items within the new vault configuration are to incorporate all non-ferrous materials. One unique aspect to the project is the introduction of a quench vent and pressure relief vent which in case of a failure of the superconductive magnet s liquid helium escaping at a temperature of 4.2 Kelvin (-571.2 degrees C). Thus, from the MIRI-Linac unit an 8 diameter quench pipe is extended through the 3'-6" thick concrete wall, up the building s facade to 18 above the top of the roof parapet. There are a series of seven equipment items located in the Equipment Room, each of which provides an operational service to the MRI-Linac through under slab trench connections to the vault. Lastly there is an 18 long counter at 3 AFF which houses the control computers and monitoring systems as used by the support technicians overseeing the patient s modality being employed at the time. Architectural Layout will be as shown on the drawings and specifications to provide the construction of a new MRI-Linac vault as well as support areas/functions which include a tech work area, equipment room, UPS room, office, storage, changing room, and patient toilet Construction including metal framing, insulation, drywall, hollow metal frames, copper RF-shielding (wall, ceiling, and floors), fiberglass dowels/re-bar, Unistrut ceiling support, wood doors, acoustical suspended ceilings, custom casework, fire extinguisher cabinet, signage, related toilet room accessories, etc. Interiors Finishes include painting, casework, wall protection, rubber base, solid surface, welded sheet flooring, luxury vinyl tile, porcelain tile, and acoustical ceiling tile. FF&E: Furnishings and Equipment included in the construction documents is based on VA standards. The list of equipment and furnishes to be provided is listed in the construction documents. Mechanical The project includes a new roof mounted 35-ton chiller to support the new MRI Linac machine. The equipment will be mounted on the same roof as the existing chiller. A new 2½ chilled water supply and return riser will be piped down from the roof to the MRI Linac floor where branch piping will serve the equipment To cool the Equipment Room, a 3-ton CRAC unit will be mounted in said room and connected to the new chiller. The CRAC unit is capable of cooling, heating, dehumidifying, and humidifying. A new split system will also be provided for the UPS located in the Electric Room. Inside the existing Linac vault, there appears to be enough air flow to serve the new machine, however, there may be operating issues with the system (because of existing complaints). In lieu of providing a new unit, the Engineer recommends the Contractor employee a service technician to inspect the unit and controls to trouble shoot any potential issues. Each HVAC duct and diffuser in the vault shall be replaced with non-ferrous aluminum ductwork, diffusers, and grilles. RF wave filters will also need to be installed in the ductwork at the vault s shielded edges. The MRI Linac manufacturer requires an 8 cryovent piped to the exterior and VA Standards also call for emergency exhaust (which is accomplished by a ceiling mounted inline exhaust fan connected to the vault s return ductwork). Also, the manufacturer also requires a small exhaust system to cool the patient using recirculated room air. Refer to the mechanical documents for a graphic description of work and airflows based on US Department of VA HVAC Design Manual: 6 total air changes/hour (ACH) based on room type and 2 outside air changes/hour requirements with constant air volume. Existing HVAC/Mechanical System Existing fan coil units, supply duct and diffusers, and return duct and grilles in the project are to be removed. Existing steam and condensate return piping is to be removed back as close as possible to associated risers around the project s perimeter, valved and capped in the ceiling. Existing chilled water supply/return piping, and condensate drain piping from each fan coil unit will be removed back to the main branches above the corridors. Any unused are to be valved and capped near the main branch above the ceiling. Existing outside air duct branches to each fan coil unit will be removed back to the main outside air duct above the corridors of the space. Existing exhaust duct branches and grilles in the project space are to be removed back to the main exhaust duct above the corridors. Any unused main duct penetrations are to be patched and sealed above the ceiling. Existing Sanitary/Vent Systems Existing vent branch piping in the project space ceiling serving demolished fixtures will be removed back to the existing vent risers. Existing Domestic Water Service Existing domestic cold/hot/recirculation water piping serving demolished fixtures will be removed back to existing risers. Medical Gas Existing capped oxygen, medical air, and medical vacuum branches to be utilized with new zone valves and alarm panel. New medical gas piping to distribute to medical gas outlets. Sanitary/Vent Systems System Material: cast iron pipe with no-hub connections.
