The Structural System
The Structural System
Optimizing construction speed and accommodating a schedule spanning two Winnipeg winters requires a hybrid structural approach. The base of the building—comprising the underground parkade and the two-level commercial podium—acts as a rigid "transfer table" constructed from Cast-In-Place (CIP) concrete. Level 3 upward transitions the residential tower to a factory-manufactured precast concrete system utilizing pre-stressed hollow-core planks. This significantly mitigates the risks of cold-weather concrete curing while maintaining the high acoustic and fire-resistance properties required for residential occupancies.

Subsurface Conditions
Subsurface Conditions
Borehole data reveals a variable soil profile consisting of complex fills, glaciolacustrine clays, and a dense glacial till layer where auger refusal occurs. Critically, a high groundwater table was observed at approximately 1.65m below grade, necessitating robust dewatering and buoyancy mitigation strategies.
Foundation Selection
Foundation Selection
Safely transferring the seven-storey loads to competent bearing layers without the caving and winter-curing risks associated with bored CIP piles requires the design to utilize Driven Precast, Prestressed Concrete (PPC) Hexagonal Piles. These displacement piles can be driven directly through the high groundwater table.
Excavation & Retaining Walls
Excavation & Retaining Walls
Excavation for the parkade utilizes a Soldier Pile and Lagging shoring system to maximize the site footprint while protecting adjacent municipal infrastructure. The permanent perimeter utilizes rigid CIP concrete retaining walls integrated with weeping tiles and elevator pit sump pumps to manage hydrostatic pressures.

Split-Frontage Servicing & Remediation
Split-Frontage Servicing & Remediation
The legacy gas station and underground storage tank (UST) on the northeast corner require an aggressive "Excavation and Disposal" remediation strategy to maintain the July 2026 construction start. Mitigating environmental risk during construction involves splitting utility servicing: pressurized domestic water ties into King Street, while gravity-fed combined sewage laterals are routed south to Alexander Avenue, safely bypassing the contamination plume.
Stormwater Management in a Combined District
Stormwater Management in a Combined District
The site, located in a combined sewer district, must strictly control post-development runoff. A hybrid system handles 1:50 year storm events: an underground detention tank throttles peak discharge, while roughly 10% of the site is green space.
Sustainable Design
Sustainable Design
Our sustainability strategy actively limits our environmental footprint, keeping embodied carbon low by utilizing an SCM concrete mix and prioritizing locally sourced materials. We've optimized the building's orientation and window placement for natural daylighting, and we are heavily supporting active transit with dedicated cycling infrastructure and EV charging stations.
