Kelsey Structural APC

Provided the structural retrofit design of an existing 4.15 MG Washington Tank located in an area of extreme seismicity. The retrofit design of the AWWA D100 welded steel tank included a new concrete ringwall foundation, retrofit anchor bolts, chairs welded to the existing shell, and operating height recommendations to prevent shell and roof damage during seismic events.

Performed a structural condition assessment of the Plant 2 facilities, including two well structures, a booster pump station, and a welded steel reservoir. The work involved site investigations, seismic analysis, and a comprehensive series of technical memoranda summarizing findings with improvement recommendations and cost estimates.

Performed structural condition assessment, structural and seismic analysis, and rehabilitation design of the existing Coronado Water Tank 1021 at Naval Base Coronado. The project progressed to design and construction, where the existing roof was replaced with a modern steel roof system to provide adequate freeboard, new coatings, a cathodic protection system, and safety features.

Provided structural design for the rehabilitation of the Grossmont Tank, a 135-foot tall dual-compartment potable water storage tank. The project included a new elevated catwalk structure with a safety cable tie-off system, a large hinged access bulkhead door in the lower shell, and repairs to multiple platforms, hatches, and ladders.
