Three levels down, ready for the tower above
Aldermoor needed a finished underground parkade so their tower contractor could start on a fixed date, with no room for delays below grade.
At a glance
- Client goal: Parkade ready for tower start
- Delivery deadline: Tower crane mobilization date
- Site constraint: High groundwater near the Bow
Digging deep next to the river
The site sits close to the Bow River, and the water table was higher than the geotechnical report expected. The excavation filled faster than a normal pump setup could keep up.
We brought in a dewatering system within a week, adjusted the shoring design with the engineer, and kept the concrete pours on schedule through a cold December.
Heated, hoarded, poured on time
Our equipment team ran the excavators, pumps, hoarding and heaters as one operation, so the concrete crews found every level dry, warm and ready.
Key milestones
- Excavation complete / Week 9 / Dewatering running, shoring signed off
- Lowest slab poured / Week 21 / Poured under hoarding at minus 18
- Handed to tower crew / June 2023 / Parkade complete on the planned date
A dry parkade, on the date
The tower contractor mobilized on the planned date. The parkade has stayed dry since, including through the 2024 spring runoff.
By the numbers
- 312 / Parking Stalls / Across three underground levels
- 14 m / Excavation Depth / Shored and dewatered
- 10 Months / Dig to Handover / Through a full winter
Digging below grade?
Excavation, shoring and dewatering set the pace for everything above them. We can review your geotechnical report before you price the job. First conversations cover soil, water and access.
