300 CATHEDRAL STREET APARTMENTS

Client: Ziger/Snead LLP
Location: Baltimore, MD
Size: 8,500 SF

CFR provided MEP engineering design services for the conversion of an historic Baltimore building into 55 rental apartments. This project won CFR the 2015 Historic Preservation Award for Adaptive Reuse & Compatible Design. Being a historic façade, there were no wall penetrations. The renovation included the design of new bathrooms for each rental unit, as well as an exercise room. Mechanical: CFR’s schematic design considered life cycle costs of the systems and we worked with the Owner to come to a quick decision on the best approach considering maintenance, sound, energy, performance, etc. The Owner chose a central water-source heat pumps system, reusing the existing BAC closed circuit cooling towers located in the basement mechanical room. Mechanical ventilation and exhaust tied into a carbon monoxide controller in the parking area. CFR also provided a central corridor makeup air system. Plumbing and Fire Protection: Redesigned all basement garage drains as required, resized and designed proper building sanitary mains and services, as well as domestic water mains and services. The existing 30 HP fire pump and sprinkler main risers were reused. Electrical: Existing 800 amp and 1200 amp services were reused with meter stacks located on each floor in the electrical rooms. These rooms were combined into a electrical room and telephone/data closet
