The Plus-15 challenge
Calgary's unique deterrent challenge is the Plus-15 elevated walkway system — 18 km of climate-controlled bridges connecting downtown buildings, with 62+ entry-plaza ledges at street-level transitions. Each transition point is a high-traffic grind opportunity where outdoor deterrents meet indoor architectural hardware. We engineer these transitions with matched finishes — bronze patina inside, brushed stainless outside — so the visual line stays consistent.
Downtown Calgary climate is Zone 7 with -7.1°C average winter, 128 cm annual snowfall, and 1.8 m frost depth. Corrosion risk is low — Calgary's dry continental climate doesn't drive the salt-air pitting seen on the coasts. 304 stainless is fully sufficient for inland deployments.
We coordinate with Calgary Parks and Calgary Transit through their Approved Vendor List (initial agreement 2023). Recent installs include Stephen Avenue commercial-tenant ledges, East Village waterfront benches, and CTrain station handrails at four downtown stations. The Eau Claire redevelopment is a 2026 deployment opportunity — we're in the spec-review phase with the project's hardscape architect.
Highest-demand zones in Calgary are Stephen Avenue, Plus-15 entry plazas, East Village, Eau Claire, and we coordinate with Calgary Transit across the network's 1800 transit shelters for platform-edge benches and shelter handrails.
Standard procurement runs through Alberta provincial portals and the city's tender system with the $50K direct-purchase / $50K+ public RFP threshold. Default spec is 304 stainless — low chloride exposure means no marine-grade upgrade is needed unless proximity to brine sources changes the calculation.
We respond to Calgary RFPs within 5 business days with stamped engineering, AODA / accessibility-code conformance letters, and bonded-contractor accreditation. Install crews carry $5M general liability. Warranty: 10 years on coatings, lifetime on 316L marine-grade structural elements.
