Bravo Churchill

Built to function as a supermarket, the Bravo Churchill project is a five-level, box design building. The facility houses two underground parking levels, one store level and two mezzanines.

Slabs were cast-in-place and supported with columns, beams and frames poured in place as Tilt-Up panels, with the store area constructed of metal structures and a metal deck roof. With both concrete and metal structure beams, the store level floors have a polished finish, and the internal load structure is formed by concrete columns. The mezzanines are supported by steel beams working as a secondary structure and a concrete cap. Tilt-Up panels, designed to act as retaining walls in the two lower levels, support gravitational and lateral forces in the upper levels. The elevated slabs were designed using a system of one-way ribs, supported by concrete frames with a reinforced concrete cap. Lower level panels are surfaced with a light, flexible geo-composite material, which has a drainage core to avoid humidity complications.

The concrete frames for the lower levels were cast as Tilt-Up joined by cast-in-place beams after erection in order to reduce construction time.
