Tishman Speyer commissioned the design and construction of a 26 story class “A” high rise office building. The building is located in the South of Market area of San Francisco.


Install all the mechanical equipment on the roof and in a rooftop penthouse. Consisting of Boilers, Chiller and Cooling Towers. LEED and sustainable building design goals were at the forefront of the Owner’s vision for the development. 535,000 square feet gross area.



All the mechanical equipment is located on the roof and in a rooftop penthouse which consists of Boilers, Chiller and Cooling Towers. The building has a dedicated chilled water loop to serve floor by floor air handling units. There is a condenser water loop riser to serve future tenant supplemental cooling needs which can run 24/7. Tenant loops were partially run on each floor for ease of future tenant build out. Due to the tight floor to floor distances there was a substantial effort completed during the pre-construction effort to maintain the 9’-4” clearance to duct work. The project was delivered on time.
