Z2DA--D/B Renovate SPS 542-21-206

GENERAL: This project is not for a full renovation of the SPS. Instead it is to replace the HVAC system for this space. The main Sterile Processing Service (SPS) space is in the basement of Building 4. The HVAC system serving this space is 2600 cfm modular air handling unit (AHU) located on grade outside near where the SPS space is located. Cooling is by the campus chilled water system, and heating is by hot water fed from the building s heating water system. Humidification is steam generated clean steam utilizing an in-line water softener. Two inline exhaust fans are located in the existing mechanical room adjacent to the SPS, and discharge through a louver at grade. There is no exhaust filtration. This mechanical room also holds the two sterilizers. This arrangement does not meet current VA standards. The existing system is not reliable, does not meet current VA standards, and has no redundancy. WARRANTY: All services provided by the contractor, as well as parts replaced shall come with a one (1) year warranty (minimum). All labor, tools, supplies, transportation, and equipment associated with the replacement of warranty items shall be provided by the contractor at no additional cost to the Government. SPECIFICS: The scope of this project is to hire a Design/Build team with the principal objective to provide a fully redundant HVAC system, conforming to current VA standards, with a cooling source independent from the campus chilled water system. The intent is that the existing ductwork system in the occupied space will remain, other than minor modifications, in order to minimize disruption to the SPS services. The scope includes provision of the following: a barrier between the sterilizer area of the mechanical room and the remainder of the mechanical room, cooling and ventilation of the sterilizer equipment area to meet current VA standards, bag-in/bag-out HEPA filtration of exhaust, resealing of ductwork to the extent practical, and limited reconfiguration of ductwork if required to facilitate efficient air balance, complete air balance of the SPS system in accordance with NEBB standards, coordinated with controls water balance of existing to remain chilled water and heating water pumps and mains, and reheat coils within the SPS space in accordance with NEBB standards replacement of any controlled devices serving SPS space which are not optimally functioning revision of the existing exterior handicap ramp up to the First Floor and modification of sidewalks as required to facilitate adequately sized and secured mechanical equipment area on grade, all required fencing, and site restoration. The scope of work includes but is not limited to the following: Evaluation of existing conditions, Site analysis and programming and design charrettes as required, Subsurface/geological evaluations as required, All associated life/safety modifications, Modifications to all building systems and utilities as required, including relocations of underground utilities and building tie-in locations, and relocation of the existing basement level mechanical service room if required for the new renovations. Implementing value-engineering decisions to meet required construction budget, Involvement of a certified industrial hygienist (CIH) to evaluate the work area for asbestos containing materials and lead paint, and to incorporate the necessary guidance in the construction documents as applicable, Providing submittals and final documents as indicated below.
