Short write-up about the pour here:
http://skyrisecities.com/news/2016/0...raft-slab-pour
Stats from the pour, via Stantec:
- Raft sits on 39 piles, 1.8m in diameter, deepest of which runs 80m into the ground (a separate source indicates that these
may be the deepest ever used in an office tower in North America)
- Typically raft slabs act as one big footing and bear directly on the soil, but because of the height and loading of this tower, piles were also needed
- 760 tonnes of rebar was used for the raft slab
- 2800 cubic metres of concrete was used
- Raft Dimensions are 24m wide x 36m long x 3m tall
- Pour start time 5am, end time 3pm - roughly 10 hours
- About 311 concrete trucks were needed
- Pour rate was ~300m3/hr; ~33 trucks every hour
- Largest continuous pour in the city's history
