Phase IV Expansion and Remodel Project at John Muir Medical Center – Walnut Creek Campus. The 400,000 square-foot expansion added a new, five-story tower, underground loading dock and a Central Utility Plant to the medical center’s Walnut Creek campus. The new tower is a steel-braced frame with concrete slab over metal deck. The main lobby features a cast in place concrete water feature rotunda. The hospital also features several gardens with architectural concrete at various roof levels.
Video 1 – Conco was responsible for all of the cast-in-place concrete, formwork, rebar, shotcrete and concrete pumping. The 4,600 cy mat foundation pour began on January 26th at 2:30 AM and was completed by 9:00 PM. Conco is targeting January 2014 for the topping out of this 42 story project.
Video 2 – Conco shot a time-lapse video of a full day on our 815 Pine project. The video was shot from the tower crane and shows the full concrete pour sequence of deck and all the vertical concrete in 1 shift. It goes quickly, but the order in which they pour is post-tensioned slab outside the core, post-tensioned slab inside the core (they are pouring through trapdoors in the core work deck), core walls, then columns.
