Scheeser Buckley Mayfield LLC provided mechanical, electrical and civil design services for a new 300,000 square foot four-story medical building housing a Heart Center, Women’s Center, Emergency Department, connecting to the existing Aultman Hospital. The building opened in March of 2006 and has a helipad on its roof. Fire protection includes a fully sprinkled building with a fire pump. Also, the design includes a foam extinguishing system for the helipad. Central plumbing equipment and systems (gas fired water heaters, water softeners, booster pumps, sewage ejectors) which are required to serve the building and are independent of any existing plumbing equipment and systems now serving the adjacent hospital buildings. A complete system of direct digital controls was designed for all HVAC equipment. Interior lighting system for the subject buildings and spaces includes energy efficient lighting systems that utilize, in general, T8 fluorescent lamps and electronic ballasts. Building exit signage is connected to the buildings emergency power distribution system. Exterior lighting systems for all new walkway areas and parking lots for the new building is included. The hospital was built over two existing public roads. Civil design work included relocating a public 42” storm sewer, public 12” water main, and public 10” sanitary systems to allow these roads to be vacated. Additional site civil design work includes surface parking lots, delivery and car accessways, and utility extensions to building. The work included a water and storm system analysis to evaluate existing capacities and flow rates. The existing storm sewer was determined to be undersized to handle current storm water discharge and video inspections showed that the existing pipes were no longer structurally sound. A new system had to be installed while keeping the existing system active and functioning. The penthouse mechanical room, which was constructed and erected on the roof of the building, houses a central chilled water plant with a capacity of 2000 tons. This chilled water plan was cross connected to the existing hospital chilled water plant. Both will function as one plant to optimize energy consumption. Also, the penthouse contains all air handling units, steam generating equipment, and heating system equipment. SBM also performed a commissioning of the temperature control system on the project to ensure proper operation of the chillers, boiler, and air handling systems.

Scheeser Buckley Mayfield LLC performed mechanical, electrical and civil design for a new 200,000 sq. ft., 5 story addition to the existing hospital building. The building is expandable up to ten stories so future capacity was designed into the building to support five stories initially with medium voltage growth to ten stories. Design included lighting, receptacles, and systems devices for 70+ patient rooms, 9 Cath/EP labs, and various other spaces. 12.47 KV was extended from the main hospital building through a tunnel system under Medical Plaza Building A to an indoor 12.47KV switchgear arrangement. This arrangement is setup to allow for this building to accept redundant feeds from the utility and be taken off of the current system. The indoor 12.47KV switchgear then feeds a 2000KVA indoor dry type substation with fans stepping down to 480/277V distribution voltage. Secondary electrical closets were designed on each floor, stepped down to 208/120V and distributed to each tenant space. In some locations the electrical panels were installed flush in the walls. Lighting throughout the building was 277V with feature lighting on an indoor sculpture and waterfall. The fire alarm system was designed for high rise construction so a voice system was design with future fire fighter telephone jacks located at each stairwell. Lighting protection was designed for future extension of the building. Site design included lighting of a healing garden with sculptures, and a future fountain with a sculpture. Essential power was extended from the main hospital's emergency power distribution system through the tunnel to an emergency distribution switchboard. This emergency distribution switchboard provides power to Life Safety, Critical, and Equipment branch transfer switches and downstream switchboards and distribution panels. Nurse Call and Code Blue systems were designed for each patient care area and other code required spaces. The Code Blue system will be extended from the existing head-end equipment located in Medical Plaza Building A. Public Address/Sound Systems were also designed for each floor in multiple zones to allow each area to provide it's own music and distributed paging. The HVAC system for the building consists of central station air handling units located in the basement of the addition. Chilled water and steam from the facility's existing chiller plant and boiler plant were extended to serve the new addition and interconnected with the utility services serving the M.O.B. to provide a system loop. The air distribution system consists of VAV terminals with hot water reheat coils. A smoke control system was designed to accommodate the two-story atrium with design considerations given to the addition of future floors and extension/relocation of the smoke control fans located on the roof of the addition. Chilled water and steam/condensate piping were sized and roughed-in for future 10-story expansion. A large portion of the project involved relocating existing underground steam, chilled water, storm, sanitary, fire, and electrical utilities from within the footprint of the new addition. An early site utility relocation package was issued to help facilitate the fast track pace of the project. Phasing of the utility relocation was critical to minimize system downtime. Project also included the installation of a new 400 bhp boiler, upgrades to the existing boiler flue stacks, and a new deaerator system to increase the Boiler Plant capacity.

An early site package was issued to address ongoing flooding problems. Two major storms in 2004 dumped excess amounts of rainfall in the Ashland area. These heavy rains caused the existing public storm and sewer system to back-up and flood the hospital’s medical office building that was under construction. These floods caused damage to the new basement mechanical room. SBM completed design to remove and replace the existing public system which included control weirs and overflow structures. The design of the Heart Center building included sanitary and storm duplex pump stations with back-up power.
