Baydo timeline
• They started to drive interlocking steel sheet pile shoring in May of 2020 (page 5)
• By late July 2020, about 40% of the sheet piling was installed but many of them appeared to be refusing early and not making it design depth (page 6)
• During the driving of the sheet piling, there was damage to the foundation of the YWCA building next door and apparently some damage to an adjacent roadway
• By October 2020, the installation of the sheet piling was complete (though to drastically varying depths) and excavation began (still page 7)
• Here’s where it starts to get weirder. By January 2021, the excavation was still plodding along slowly, but the north end of the excavation had some strange horizontal lattice-type trusses installed. Shoring support? (page 9)
• Late March 2021, the center of the excavation has reached full depth and a large raft slab has been poured (page 11)
• Early May 2021, Steel angle braces have been added to support the sheet pile shoring and formwork for a central core has started. (page 13). Also on this page, it’s noted that the raft slab has now been buried under dirt (????). To add more fun, someone posted this:
Apparently it’s a new modern way of building - they are sinking it and the dirt is coming up around it. An engineering plan to make a foundation deeper than your building; originally used in Denmark and just approved by engineers to be used in Canada in 2020.
Simple physics really, with that big of a piece of concrete floating on blue clay compensates for any shifting the building may encounter due to external forces.
You see the steel beams attached to it, they will attach to the fulcrum system that will tie in to the counterweight of the elevator once the building is in place, making it a higher quality tower than No1 River Landing.
• September 2021, and the raft foundation is still buried, but more excavation has taken place (very slow progress through summer), but by the end of the month the tower crane had been erected (page 16)
• November 2021 and the core wall are underway. They are precast wall panels that are bolted together. Unique system to most of us (page 18)
• January 2022 and work on the core has been continuing very slowly through the fall and early winter. There is now additional steel structure being erected in the excavation (page 22)
• February 2022 sees hollowcore precast concrete slabs being placed on the steel structure (page 23)
• April 2022 and the steel framing and precast panels are clearly above grade and a cast in place slab has been poured around the core. (page 25)
• By June 2022, we’re getting a better idea of the typical building structure. The core walls are now conventionally formed cast in place concrete. The main structure is steel and they are using very thin precast floor panels that then receive a topping slab (page 26 has some good close-ups of this)
• September 2022, and a second tower crane has been erected, while progress on the north tower structure continues slowly (page 28)
• By December 2022, they have 7 floors of the north tower erected (page 29)
• Work continues slowly through spring of 2023 and the north tower begins to take shape. Page 30 contains a great photo showing the progress over the past year
• By June 2023, the concrete core of the south tower is a few floors above grade (page 31)
• Last half of 2023 sees continued slow progress. Page 36 has a photo comparing January 2023 to January 2022
• North tower appears to be topped off about June 2024, 4 years after the project began (page 38)
• June 2024 – present, exterior and (presumably) interior finishes progressing on north tower. South tower structure continues at a snails pace.
