Ithaca weather is not accommodating. Originally, the pour for the concrete slab was supposed to take place on April 3rd. It’s tricky, because this is a large footprint and the building is very heavy, necessitating a thick slab – 30 inches thick. That has to all be poured at once, without any potential interruptions like rain or snow, which can weaken the concrete as it cures (upsets the mix and water balance). That was rescheduled the first time due to winter weather, and was expected to take place on the 11th, which was rained out. 4/16 was also cancelled due to winter weather. Finally the concrete was able to be poured on the 23rd.
In the photos below, you can see some wood forms are still in place for smaller sections (entryway, lower right of site). The vertical concrete column bases are being poured (note the squares of vertical rebar in the sections yet to be encased), with steel plates atop the finished column to tie into the steel beams. The hole in the lower right (southeast) corner is for one of the elevator cores. Taylor the Builders will have this heading skyward in short order.

Ithaca, where you can have outdoor events cancelled due to winter weather in April. It’s been a long, cold, wet winter.
