Clark Construction Group and AC Martin fast-tracked the delivery of a $115-million residence hall, completing programming, design, documents, permits and construction in just 29 months. Sited on a former parking lot, the project combined an existing 600-bed freshmen residence hall with the new 200,000-sq-ft Huaxyacac Hall, creating a new hub for first-year students.
To preserve a natural canyon adjacent to the project site, the team installed soldier piles along the canyon edge and built a retaining wall. Crews utilized a modified rig to drill tiebacks over the top of the retaining wall to help keep personnel and equipment away from the canyon. Once the retaining wall was back-filled, prefabricated rebar cages were lowered and placed on the outside face of the lagging walls. A scaffold was then erected between the lagging wall and the canyon edge to shotcrete the lagging wall.
