SSU Modular Buildings Site Infrastructure - Santa Rosa, California

Sonoma State University

Posted: September 27, 2022 | Projects

Modular units (for CAPS and some classrooms at Sonoma State University) were placed on the east side of Salazar Hall. CAPS (Counseling and Psychological Services) permanently moved from Stevenson Hall 1st floor to modular unit Building 17-A (East of Salazar Hall), January 29, 2020.

Modular infrastructure offers many advantages:    

• Environmentally friendly construction process. Modular construction reduces waste and site disturbance compared to site-built structures. The controlled environment of the factory allows for more accurate construction while allowing the extra materials to be recycled in-house.    

• Low waste. With the same plans being constantly built, the manufacturer has records of exactly what quantity of materials is needed for a given job.    

• Speed of construction/faster return on investment.    

• Flexibility. One can continually add to a modular building. When the needs change, modular buildings can be disassembled and the modules relocated or refurbished for their next use reducing the demand for raw materials and minimizing the amount of energy expended to create a building to meet the new need.    

• Indoor construction. Assembly is independent of weather, which increases work efficiency and avoids damaging materials.    

• Improved Air Quality. Many of the indoor air quality issues identified in new construction result from high moisture levels in the framing materials. Because the modular structure is substantially completed in a factory-controlled setting using dry materials, the potential for high levels of moisture being trapped in the new construction is eliminated.    

• Quality. Combining traditional building techniques, quality manufacturing and third-party agencies who offer random inspections, testing, and certification services for quality control, commercial modular buildings are built in strict accordance with appropriate local, state, and national regulations and codes.    

• Modular buildings can also contribute to LEED requirements.
