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 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.

This project was a renovation of an existing facility and the construction of new buildings. In the renovation, the entire campus was consolidated into a smaller area. Due to this consolidation, a new boiler plant was designed to replace the existing steam boiler plant. Eight 2000 MBH heating water boilers were installed to handle the building heating requirements, as well as the domestic hot water heating. These boilers were dual fuel (natural gas and liquefied propane) to allow the system to remain in operation in case of an emergency where natural gas was no longer available. Also, a new 200 ton air cooled chiller was installed to be cross connected with an existing 200 ton chiller, designed by SBM on a previous project. It was estimated the replacement of the steam boiler plant and associated tunnels with a nearby heating water boiler plant will allow for an approximate 24% reduction in utility costs due to more efficient equipment, better control strategies, removal of auxiliary steam equipment, and the elimination of heat loss in long runs of steam piping. This project also replaced all the existing constant volume air handling units with variable volume air handling units with economizer cycles to further save on utility costs.

These utility savings allowed the State of Ohio Office of Energy Services to provide a sizable amount of money to the project.

The campus consolidation required the design of a new vehicular and pedestrian ingress and egress, new parking lots and a lane boulevard entrance, storm water management and evasion control designs were completed along with site and campus underground electrical and communication feeders.

SBM has provided extensive commissioning on this project to allow the two chillers, installed under different projects, to operate in unison in response to the cooling load.

The project wrapped up all previous phases of the construction projects at the facility to allow for one seamless campus.

This project included the conception and design of a central chilled water plant to serve numerous Residence Halls, academic buildings and auxiliary buildings at the east end of the Kent Campus. The new two story plant was located in a separate building designed specifically for use as a chilled water production facility. The system was designed as a primary/secondary distribution system with variable flow pumping to the connected buildings. The production of the chilled water was accomplished with two 850 ton high efficiency electrical centrifugal chillers and one 850 ton low pressure steam absorption chiller. The plant was designed to accept a future 850 ton chiller as load increases on the campus. The chiller operation sequence was custom designed by SBM to allow optional use by operators of steam energy or electric energy based on time of day or other circumstances. The temperature control systems were a combination of pneumatic moving devices and digital sensors, and the logic was provided by a Trane digital chiller control system integrated into the campus Johnson Controls Metasys system through the use of BacNet. The project also included the connecting of piping to numerous existing buildings with existing chillers which were ready to be retired, and Commissioning Services provided by SBM. The electrical design for this project included connection to the campus 13.2KV loop with two loop type pad mount transformers. Two services entered the building, one at 4160V for the centrifugal chillers and one at 480V for miscellaneous pumps and mechanical equipment. The 480V was then stepped down in the building to 208/120V for general purpose receptacles. This project also involved several motor control centers, cooling tower connections and medium voltage chiller connections. In addition, a transformer vault was created and a medium voltage manhole was designed for the site.

During the commissioning phase, SBM worked hand-in-hand with the balancing contractor to assure all mixing bridges were setup as designed to deliver only the required cooling capacity at each building to minimize energy consumption. SBM also worked diligently with both Johnson Controls and Trane control contractors to assure the correct information was being transmitted between the two control systems to accomplish the design objectives. At one point in the commissioning phase SBM staffed the project with six individuals located at each building connected to the system. It was important to know what was happening in each building at exactly the same time. This coordinated effort allowed SBM to verify the control operation and fine tune the system to operate at peak efficiency.

The Marshall University Bio-Technology Building is located on the north side of the Marshall University campus in Huntington, West Virginia. The building consists of four floor levels with a bridge over 3rd Avenue to the existing Science Building. The project included a 300 seat auditorium, vivarium space including associated cagewash / sterilization support spaces. A significant portion of the building (approximately 50,000 sq. ft) was associated with different types of laboratories including general research, teaching laboratories as well as specialized research laboratories. The specialized research laboratories included laser equipment as well as electron microscopes. The facility included provisions to allow for the addition of BSL level 3 spaces. The building also included faculty and graduate assistant research office space.

SBM was responsible for a HVAC, Plumbing, Electrical, Telecommunications and Fire Protection design and commissioning. During the commissioning process the systems were started up and tested. Not surprisingly, considering the complexity of the building, a number of problems were discovered. Examples of the problems discovered and how they were corrected are listed as follows:

  1. The high purity lab water piping system had a tendency to sometimes spring a leak whenever the system pumps started. The leak always occurred at the faucet compression fitting connection. This problem was diagnosed as a “water hammer” problem. The problem was corrected by installing soft start starters on the system pumps.
  2. The cooling towers for the chilled water system were shipped with the wrong motor pulleys and undersized hot water basin nozzles. The undersized nozzles was easy to diagnose because the cooling towers overflowed when balanced to the specified condenser water flow rate. The wrong motor pulleys were discovered when testing showed the motors were pulling significantly less than name plate amps. Both issues were resolved by parts and technicians provided by the cooling tower manufacturer.
  3. Of the many pieces of Laboratory equipment on the project, the casework contractor provided two biological safety cabinets that were not the correct style. All biological safety cabinets on the project were to be of the Class 2 Type A configuration. As such the ductwork systems for the biological safety cabinets were designed with a thimble style connection. In the two cases noted, Class 2 Type B2 configuration units were provided. These safety cabinets were not compatible with the ductwork system and were changed to the specified style.
