Construction of two 2.5 million gallon post tensioned concrete reservoirs that hold drinking water for the City of Los Gatos, CA. Scope also included demolition of the two existing earthen based reservoirs, disposal of arsenic, lead, and asbestos based materials, regrade of the construction site, and improvements to the access road. By redesigning the grading plan, we were able to sequence construction activity to allow for construction of both post-tension reservoirs concurrently.
