The Bowie Health Center project consisted of the total renovation of 22,000 square feet emergency department, addition of CT scan area to the emergency department and total renovation of the adjacent administration building. The Bowie Health center is a part of the university of Maryland Medical System (UMMS).

• Our scope of work consisted of providing mechanical, electrical, plumbing and structural  engineering design and construction phase services for the renovation and new areas of the emergency department and administration building.

• The mechanical system for the emergency department consisted of two packaged gas fired variable air volume roof top units serving the  renovation areas and a packaged gas fired constant air volume roof top unit serving the new addition which included the CT scan area. Air changes and air pressure  relationship of various areas were carefully studied for designing the HVAC system. Various spaces in the renovated emergency department were  zoned to be served by dedicated VAV boxes equipped with hydronic heating coils based in their occupancy, use and exposure. The hot water to the  heating coils of the VAV boxes was provided through the existing steam to water heat exchanger and new heating water pumps in the mechanical  room.

• The medical gas (oxygen, air) and vacuum piping were provided and extended to the outlets in the examination rooms. Bulk oxygen was provided for the emergency department and adjacent building which houses the surgery center. The existing vacuum pump in the mechanical room was reutilized to serve the vacuum outlets and new air compressor was provided to serve the new air outlets.

• The existing electric service was adequate and reused for renovation project. Due to frequent power outages in the area, the majority of the building was designed to be served by a new 550 KW diesel generator. The diesel fuel for the generator was provided by the existing underground fuel storage tank which was recently upgraded.

• The major challenge was the phasing of the project in order to maintain the emergency department and administration building in operation throughout the construction phase. In order to accomplish this task, a detailed demolition and new work drawings for each phase of the project for the mechanical and electrical system were prepared.

• The structural work included the design and construction phases for the CT-Scan room addition, support of the mechanical roof mounted equipment and other structural related work in the renovated areas.
