PLUMBING


This project involved the renovation of a late 1960’s residence hall to provide office spaces for multiple administrative functions including the Office of the University Architects. The original building was approximately 23,500 square feet with an 8’10” floor to floor height in most areas of the building. In addition to the renovation, a new 2,700 sq ft entry was also incorporated into the project to address accessibility issues with the existing building. Sustainability was a key focus for this project in order to achieve LEED Gold certification. The original building envelope was analyzed and improved incorporating additional insulation and window replacements. Green innovations included low-flow plumbing fixtures, high efficiency lighting, VRF zone heating and air conditioning systems, and a dedicated 100% outdoor air handling unit containing a heat recovery wheel. The energy efficiency of the VRF system and its ability to capture and reuse waste heat contributed to a high energy savings. The high degree of temperature and lighting controls installed also earned points for maximizing user comfort.

The mechanical and plumbing infrastructure was replaced in its entirety. A variable refrigerant flow (VRV) system was designed for the building with multiple indoor units connected to two separate outdoor heat pump units. The system provides simultaneous heating and cooling to the connected indoor terminal units. This allows heat to be transferred through the refrigerant to minimize the power usage of the outdoor unit. The heating units absorb heat from the refrigerant and the cooling units reject heat to the refrigerant. This enables the system to achieve very high efficiencies since simultaneous heating and cooling is required in the winter months as well as most of the spring and fall months. Ventilation air is provided through a 100% outdoor air heat recovery unit with tempered outside air ducted to the individual spaces. Energy efficiency was designed into the project through the use of the variable refrigerant flow equipment and a heat recovery air handling unit to provide ventilation for the building using a heat recovery wheel. State-of-the-art digital controls were designed to facilitate energy conservation and to assist in systems monitoring and proactive maintenance.

Electrical design included extending a 480V service entrance from an exterior unit substation to the building. A complete new distribution system was designed throughout the building. New lighting was designed incorporating T-5 lamps and energy efficient ballasts. Downlighting incorporated LED lamping technology. Occupancy sensors were incorporated for lighting controls with complete building control via Lutron control system. This was further integrated into the Johnson Control System to systematically shutdown unoccupied spaces. A complete Cat. 6 telecommunications system was also designed with rack, faceplates and patchpanels for turnkey project for an electronics vendor.

Close coordination was necessary with the mechanical, plumbing, electrical, and architectural design to maximize ceiling heights while working within areas of the buildings with 8’2” clear height from floor to bottom of precast structure above.

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. Mechanical and electrical systems were designed to the Labs21 low energy lab standards.

The mechanical and electrical systems required a level of redundancy not required on most projects. The vivarium space required backup systems to the backup systems in an attempt to assure that the experiments would not be affected by utility outages. An imagine suite is located on first floor. This space houses extremely vibration sensitive equipment. Any equipment which could potentially generate vibration and noise was located in penthouse 3 floors above this space. 99.99% high efficiency terminal HEPA filter was designed for all lab area in this suite. This electrical redundancy included two independent utility feeds from separate utility substations as well as on site emergency power generation. The electrical and building automation system for the building was interfaced so that the automation could determine which HVAC, chillers, etc. were allowed to run based upon the utilities which were present. This resulted in a complex sixteen scenario utility scheme which was integrated into the building automation system. Each piece of equipment was reviewed as to how it was to function in the event of any one of the utilities and generator outage. 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.

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:

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.

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.

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.

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. Commissioning services were also provided for this project by a separate team. 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.
