CFR is providing MEP and Process Piping engineering design and construction administration services to create a Class 1000 cleanroom room by consolidating several spaces in the Mitchell Engineering Building at Morgan State University. The new space will be ~4,000 SF and will be made up of ~five(5) spaces currently designated as Mitchell 125, 127, 142, 144 and 146. Mechanical design includes new air-cooled chiller, exhaust scrubbers to handle acids and solvents, ducted fume/laminar hoods and exhaust for chemicals and gases, exhaust connections for fume hoods, and recirculation HEPA units to provide required air charges. Also includes new dehumidification and humidification systems to maintain clean room pressurization requirements, roof fans, general heating, cooling, and ventilation as requirement for gas storage enclosure, as well as new air side direct digital controls to maintain cleanroom pressurization requirements with connection to existing BAS. The existing base building heating water and make-up air will be reused and the fume exhaust fans will be repurposed. Electrical design includes new sub-base fuel tank generator, panelboards, power receptacles, LED lighting and dimmable controls, and power and lighting for gas storage enclosure. Both the fire alarm and fire sprinkler system will be expanded to serve the new space. Plumbing design includes new acid neutralization system, acid resistant drain and vent systems, water softening system and drains for DI feed water, plumbing and piping distribution for humidification system, etc. Process piping design includes new lab deionized (pure) water system, high-purity nitrogen gas system, and dry compressed air system.

This project included the renovation of an existing Physics Teaching lab space (Lab 113) and lab support spaces (Rooms 111 & 117) in Regents Hall into a new research lab for the study of Condensed Matter Physics. Spaces included a Nano Lab, Synthesis Lab, Characterization Lab, and Chemistry Lab. The project also included minor modifications to Regents Hall Room 116 for uses as a faculty office and graduate student work space. Mechanical design included chilled water and associated pumps to satisfy cooling requirements for flow and pressure of the user equipment, while maintaining non-condensing temperatures within the equipment, as well as modifications to exhaust and ventilation systems. Plumbing design provided piping to the overhead service carrier with flexible tubing down to the bench-top area. The plumbing design also involved working with underground utilities, specifically modifying compressed air, vacuum, and nitrogen, while coordinating with physical space of other existing piping systems within the lab: gas, reverse-osmosis, natural gas, cold water, hot water, and hot water circulation piping, reverse osmosis supply and return piping, lab waste, lab vent, and emergency / tempered water piping. The electrical design included power for mechanical pumps, user equipment, surface metal raceway, new electrical panels, as well as new task lighting and overhead lighting with both daylight sensors and occupancy sensors.

CFR provided plumbing and electrical engineering design services for the replacement of the Plant Sciences Building’s basement RO skid and RO distribution system. The existing RO distribution piping was deteriorating and included dead legs that prevented the loop from being properly disinfected, leading to biofilm and algae growth and preventing the ability to perform high quality research. CFR surveyed the existing building system and identified all current users and drops of RO water. The new system serves the current uses and any additional drops required by the Departments of Plant Sciences and Entomology. CFR investigated the possibility of interconnecting the main building RO system distribution piping to the existing 6th floor distribution system to offer a level of redundancy. Determine if manual isolation valves can be installed in the riser to isolate the systems and allow them to operate independently or one generation skid to serve the entire building. We provided support in sizing and selection of the softening, pre-treatment, RO filter skid and storage tank, RO circulation pumps, and UV disinfection lamp housing. The RO distribution system was designed to be a continuous flow through system with the shortest possible dead leg at point of use drops. The distribution piping is thermally fused, opaque, pigmented polypropylene with thermally fused ball isolation valves and was designed for a velocity of between 3 – 4 FPS. The RO system controller has BacNet interface and connects to the building automation system (BAS) for proper operation and annunciation of any alarms. New power was designed as required for the new RO skid and pumps.

CFR is providing MEP engineering design services for the replacement of AHU-1 and AHU-5 in the UMBC Biology Building. AHU-1, located in the penthouse, is being replaced in a new location, about 40 feet from the existing location. AHU-5, located in the basement, is to be replaced in-kind. Design includes modifications of the existing concrete pads for both AHU’s. Design for AHU-1 at penthouse level includes removal of existing abandoned cooling tower, chiller, heat exchanger, and six (6) pumps to make room for AHU-1 in the new location. It also includes utilizing existing cooling tower opening to bring in the new AHU and for the new OA connection, as well as modification of floor drains in the vicinity to confirm functionality. Access for installation will be via existing louver to be removed and reinstalled or replaced. This opening will also be to crane the new AHU inside the penthouse. Crane location will be coordinated with UMBC, as well as the coordination of existing Penthouse lateral cross bracing for access of equipment. Design also includes converting pneumatics to DDC controls and VFD to serve the AHU. Design for in-kind replacement of AHU-5 at basement level includes conversion of pneumatics to DDC controls at the unit. It also includes removal of abandoned piping and pumps, as well as removing abandoned disconnects in the mechanical room, and VFD to serve the AHU.
