Abstract/Summary
This paper summarizes the efforts towards constructing formwork for 10 concrete benches. The formwork construction is a part of the San Luis Obispo Botanical Garden amphitheater seating senior project. The project included the design, construction, and installation of precast concrete benches to create seating for 40 people. The project was completed by Kyler Cruz, Brandon Keefer, Sydnee Greer, Makenna Gitchell, Devin Barthmaier, and Anthony Masarweh. The concrete formwork consisted of plywood, 2x4 lumber for bracing, rebar cages, and foam inserts. The key considerations for this scope of work included: reinforcing rebar, the number of forms built, formwork failure, and the overall weight of the benches. The initial estimate for formwork bracing material was too conservative which resulted in construction taking longer than initially planned, as well as increased spending on materials. The team also struggled to secure the rebar and foam core inside the formwork which created more work during the concrete pour. Despite the challenges that occurred, the formwork was completed in eight days and in time for the scheduled concrete pour. The formwork did not fail during or after the concrete pour and all 10 benches were poured successfully.
