The 250,000-square-foot, 15-story building will have retail and office spaces on the ground floor. The building’s unique design features a parking garage on the first five levels, above the retail stores, with the 10-story, 110-unit housing complex setback on the roof of the parking garage.
For the builders of the Rhythm complex, one of the primary goals was to build the structure as quickly as possible. To help meet this goal, the contractor, Harcon Inc., chose Doka USA as the formwork supplier. Doka’s ability to provide formwork on a tight schedule, with fast set time and fast cycle time, was a plus for the project. Doka supplied 15,000 square feet of Dokamatic tables and Dokaflex in-fill, the Doka Table Lifting System, and shifting trolleys for quick cycling of the tables.
Since the footprint of the building was so close to the actual size of the parcel of land, the contractor was very constricted as to the type of construction methods that could be used to build the structure. Originally, Harcon had decided to use conventional wood shoring as a method for construction. Although this method would fit the tight job constraints, it was very time- and labor-intensive. With conventional wood shoring, all work is hand-set – all formwork is set-up by hand and after the concrete is poured, the formwork is wrecked out by hand and moved to the next floor for hand set-up again.
What Harcon needed was a way to meet its schedule and keep its workforce as low as possible. Dokamatic tables were delivered to the construction jobsite completely assembled, including plywood, eliminating build-up cost, reducing rental costs and allowing for smaller crew sizes.
The TLS lifts the Dokamatic tables from one level to the next without using a crane. This frees-up the site crane for other jobs, so the overall work at the construction site progresses faster.
“Doka’s Table Lifting System is basically an elevator that mounts to the side of the building,” Campbell explained. “When you are finished pouring a floor, the tables are dropped down, rolled onto the elevator and taken to the next level where the tabled are rolled off and re-set.” Doka’s comprehensive safety package ensures fast, safe work procedures, both for operating the lift table and for repositioning.
Additionally, Doka’s expertise helped the contractor to achieve the desired look that the architect required. “The architect specified exposed concrete floors and ceilings,” said Campbell. “We use very high-grade plywood on our Dokamatic tables and that gives an excellent finish on the concrete.”
