Mr. Valenzuela also designed integral straddle and hammerhead pier caps, associated details, and led plan/drawing production and post design services. Mr. Valenzuela designed temporary critical sheet pile walls and anchorage systems for the entire 253 C project from Conway Rd to Oxalis Drive.
SR 408 from Crystal Lake to Conway Road, OOCEA, Orlando, Florida – Mr. Valenzuela served as project engineer for this project which had a total of nine concrete and steel bridge structures, including widenings, new ramp structures and a pedestrian bridge crossing Lake Underhill. The concrete and steel Lake Underhill bridges included 28 spans and a total of 1,700 feet across the lake. Mr. Valenzuela designed steel plate-girders, steel details, superstructure and end bent components for the 139 ft. simple-span eastbound ramp bridge over Crystal Lake Drive. He also designed AASHTO beams, end bents, deck slabs and performed bridge load ratings for the new and existing superstructures for several other bridges on the project.
