107 South Albany Street Construction Update, 10/2017

20 10 2017

With the twin duplexes on the corner of Aurora and Queen completed, local developer Stavros Stavropoulos and his local contractor Northeast Renovations Inc. have been able to turn their focus towards building out 107 South Albany Street. At this stage, the spread concrete footers, also called formwork or footings, have been finished.

As in this case, footers are usually of concrete with steel rebar reinforcement that has been poured into an excavated trench and confined by wood forms. The purpose of footings is to support the foundation and prevent settling. The portion of rebar sticking out of the footers will be bent and wired into the foundation’s horizontal rebar, tying the two components together. I’m not sure if they simply filled in the basement of the old house or if they tore the walls out before bringing in clean fill and digging trenches for the new footers (I’d guess the latter for simplicity’s sake).

It looks like the outer footings for the ground-level common space (entry, bike storage, meter room) are at a slightly lower grade than the rest of the structure, so there might be two separate sections that comprise foundation, with one at a slightly higher elevation than the other.

The next steps involve a rebar grid being ssembled and tied per specifications, elevated a few inches from the ground by plastic rebar chairs that allow concrete to get underneath the steel rods. The concrete will be poured over the rebar, and as long as the bars stay in place, the new pour is left to dry into a solid, reinforced slab foundation upon which the building frame can be built. The building itself will have a wood-frame, so when it starts to rise, it should move at a pretty fast pace.
