Who we work with

Residential, commercial, and municipal — across Ontario.

The same licensed engineering, fixed-fee pricing, and direct access to the engineer on your project — whether it's a residential structural report or a 145-unit Passive House community.

Residential

Homeowners & builders

Sealed structural drawings and permit support for additions, second storeys, load-bearing wall removals, foundations, underpinning, garages, and decks. You talk to the engineer working on your file — not a coordinator. Fixed fees, fast turnaround.

Commercial

Developers & contractors

Sealed permit drawings, Schedule 1 general review, and construction management for small-commercial, mixed-use, and institutional projects. Our engineers act as Engineer of Record and stay on the project from permit submission to final occupancy.

Municipal & Housing

Public bodies & housing corps

Full project delivery for affordable housing, municipal infrastructure, and public institutions — including Passive House and high-performance buildings. Our engineers have served as Engineer of Record and owner-side coordinator on projects from community housing to large-scale P3 programmes.

Asridge role
Owner-side project coordination

Meadowbrook is Ontario's largest Passive House multi-residential building — a 10-storey, 145-unit residence in Windsor built by Windsor Essex Community Housing Corporation. It was also the first new public housing built in Windsor in 30 years. Asridge's principal led owner-side coordination throughout.

Final airtightness result: 0.128 ACH — nearly 5× tighter than the Passive House International threshold. That result came from resolving real envelope and trades issues on site, not just modeling them. That experience informs every high-performance project we take on.
