Our team provided an evaluation narrative of the existing surgery and ICU areas’ mechanical systems in consideration of a potential building remodel. On-site data was collected from the existing heating and air conditioning, plumbing, sanitary and associated components, verifying the systems and their capacities, along with the associated routing/zoning relationships and building constraints.
We provided the mechanical engineering design criteria and the program/schematic design phase efforts, as well as mechanical options outlining the associated pros and cons. The options considered took into account design strategies aligning with the LEED for Healthcare rating system and existing mechanical conditions, as well as cost, operational efficiencies, and overall system compatibility with existing conditions.
As part of the design scope, POWER provided demolition drawings for the HVAC, plumbing and sanitary systems to properly convey the scope of work to the contractor. Following the VA’s approval of the presented project design criteria and equipment options, POWER coordinated with the architect and other engineering design disciplines to provide the HVAC, plumbing and sanitary plans, as well as the mechanical and fire sprinkler protection system specifications.
Additionally, the VA Medical Center had an existing campus pre-heating geothermal loop to provide heating for all of the HVAC air handling equipment on campus. Each campus facility had a direct connection to the pre-heating geothermal loop to access the geothermal fluid which then flowed through independent building heat exchangers to provide the specific heating temperatures required by each facility. For this project, the primary heat exchanger for Building 87 did not have the capacity to meet the pre-heating demands required by the addition of the surgery/ICU expansions. POWER’s scope for these modifications included adding a new heat exchanger and auxiliary pumps, valves, and piping components for a new pre-heating loop that could support the expansion while not impacting the existing pre-heating systems feeding other campus facilities.
A rough order of magnitude (ROM) estimate for the mechanical system, information to assist in developing the construction schedule and coordination of procurement/long-lead mechanical items was also provided.
On-site construction support included review of vendor/supplier drawings, equipment selections and submittals for compliance with design intent, compliance to any spatial limitations and compliance to codes and VA standards. All work involved with the mechanical construction, equipment installation, testing and calibration was reviewed and POWER performed a comprehensive final inspection and assisted in developing a punch list for the mechanical contractors.
