Project Description


Dabri, Inc. provided cost estimating and scheduling services for this $80 Million project during the planning, design and bidding phase as part of design-build team. Our team also provided bid package cost estimate and schedule to validate the project budget and bid scope. The 2.5-mgd San Francisco International Airport (SFO) Mel Leong Wastewater Treatment Plant consists of sanitary and industrial wastewater treatment operations. Improvements are required to increase capacity for future demands, address deferred maintenance to extend the facilities useful life, meet Title 22 Regulations, and provide a reliable source of recycled water to achieve SFO sustainability goals. This project scope included the rehabilitation and replacement of existing industrial primary and secondary wastewater treatment processes, replacement solids dewatering and handling facilities, construction of a new 8,000-SF administrative and laboratory building, and construction of new recycled water treatment processes and storage facilities.
