The new College of Marin Facilities Planning, Maintenance, and Operations Department (M & O) Building provides maintenance and safe operations for custodial services and grounds maintenance.
Due to concern of noise complaints to adjacent facilities, CSDA was brought on board to perform noise analysis from the new M&O buildings to the neighboring receivers, Kent Middle School to the north and residences to the west. Our services consist of acoustical measurements of environmental community noise and noise modeling to evaluate the efficacy of the proposed eight-foot-tall property line fence.
CSDA was retained to provide acoustical consulting for Potrero Block B located in the Potrero neighborhood in San Francisco. The project is two 7-story buildings that will consist of 157 affordable housing units with ancillary spaces (e.g., flex room, homework room), childcare center and parking.
Our services include acoustic measurements, construction site visits, design input for sound isolation, HVAC/mechanical systems, room acoustics and community noise beginning with an Environmental Noise Study and ending with Construction Administration.
CSDA was retained to work for the 266 4th Street Housing residential project in San Francisco, CA. The project is being built on a flat L-shaped parcel and will be an 8-story residential building with 70 affordable below-market units ranging from studios to-two bedroom units. The apartments will occupy floors 2-8 and the first floor will have retail space, amenity spaces, at-grade courtyard, garden, play space and a top-floor terrace. The building is situated above a future SFMTA subway station under construction as part of the Central Subway Project.
Our acoustical consulting services includes an environmental noise study, Central Subway vibration evaluation, as well as input on sound isolation, room acoustics and MEP/HVAC noise and vibration.
CSDA worked with the developer and Mithun to provide acoustical consulting for Hunters Point Shipyard Area Blocks 52 and 54 located located on non-contiguous parcels at 151 & 351 Friedell Street in San Francisco. The development consists of two buildings ranging from one-bedroom to five-bedroom units for low-income families. Offices
for building management and tenant services are located in the Block 52 building and residential amenity facilities, common to and shared between the two buildings, include a community room with kitchen, fitness room, common laundry rooms, lounge and roof terrace.
Our services include acoustic measurements, construction site visits, design input on sound isolation, HVAC/mechanical systems, room acoustics and community noise.
CSDA provided acoustical consulting services to Taylor Design for a new MRI facility in the Hospital. CSDA reviewed and analyzed the Air Handler/Water Chiller equipment installation locations and equipment sound data and calculated the expected noise levels from the rooftop equipment into the spaces below. Noise reduction recommendations including sketches and details were provided. Vibration isolation recommendations were made to reduce structure-borne noise transfer into the building.
CSDA also reviewed the MRI noise data and calculated MRI noise to the adjacent spaces as well as performing measurements and analysis of floor vibration with respect to the MRI manufacturers vibration criterion.
