Ten weeks ago today we last ran a story on construction progress at Tridel's Ten York Street Condos construction site, when the wedge-shaped 67-storey building was just about to hit ground level. The Wallman Architects-designed building is now fully at grade as the ground floor slab was poured over the last couple of days. Frequent UrbanToronto Forum contributor drum118 got extensive photography of the work, with shots giving a comprehensive idea of what is involved.

Ten York's uniquely shaped triangular wedge of a site is immediately south of the Gardiner Expressway, and north of Harbour Street and the Gardiner's Yonge-Bay-York off-ramp. The off-ramp is planned to come down next year, to be replaced by a new, less invasive off-ramp at Simcoe Street. South of the off-ramp is a parking garage which provides a great spot to perch above the site.

From above the site, drum118 was able to catch dump trucks lining up to provide the material needed to pump through the concrete placing boom. It extends many metres from a truck to where the concrete is needed.

In the image below, with a close-up following it, we can see one construction work guiding the concrete delivery pipe to right above the rebar-filled form. Steel reinforcing bars, or rebar for shot, runs through the concrete slabs, holding the concrete in tension and giving the slabs incredible tensile strength.

Seen more easily in the close-up below, the rebar runs two ways in the slabs, tying them together. Transversal ribs on each rod bond the two materials tightly. A construction worker in the centre of the shot smooths and levels the surface of the newly curing slab.

Since filled with concrete, a construction worker stands to the side of another wooden form, filled with rebar and ready for its pour.

In the middle of the construction site, the forms for the elevator core for the 735 foot tall tower are ready for their concrete too. Rebar sticks up above where the concrete is placed on the current level, and will stick up above the next floor slab to be poured too. The tops of the rods can then be tied into rebar for the floors above, creating strong, bonded walls throughout the building.
