Summit Park Office Building

The two upper floors use the "Hambro" composite floor system. The "Hambro" floor is an economical hybrid steel/concrete system utilizing the concrete slab as both the compression flange of the steel joist and the structural floor. "Hambro" results in a relatively shallow floor structure, which reduces the floor to floor, and ultimately, the building's height. Steel columns and beams support the centre section of Summit Park's two suspended floors and roof. Load bearing concrete tilt-up panels (cast on site) support the outer edges of the floors and roof. The tilt-up panels extend from the foundation to the roof providing both the cladding and exterior structure. The panels resist vertical and lateral loads, thereby eliminating the need for structural steel and x-bracing around the perimeter of the building.

The tilt-up panels are constructed with spandrel beams at each floor and at the roof. Column sections, which form the ends of the panels, support the spandrel beams. There are three continuous bands of horizontal glazing around the perimeter of the building. Notches are formed in the column sections of the tilt-up panels to allow the glazing to be continuous.

This building won an Achievement Award from the Tilt-up Concrete Association.

BMR has designed numerous innovative tilt-up structures including a four-storey office building, multi-use warehouses and structures with roof top parking.
