Our specialties

Deep expertise in Toronto's most complex project types

UTES focuses on projects that require both engineering precision and detailed knowledge of Toronto's zoning bylaws — the types of work most generalist contractors avoid.

Led by Arash Bahamin, P.Eng., every project benefits from a structural engineer's perspective before a single design decision is made.

How it works

From first call to permit approval — or project completion

The same process applies whether you need engineering drawings only, or a full design-build. We scope your needs in the first conversation.

01

Consultation & scoping

A brief call or site visit to understand your project, zoning eligibility, and whether you need engineering-only or full design-build.

02

Zoning & bylaw review

We confirm what's permitted as-of-right and identify if a Committee of Adjustment application is needed before permits.

03

Design & engineering

Drawings prepared in-house by our team. All structural drawings stamped by Arash Bahamin, P.Eng.

04

Permits & construction

We submit permits and manage city communications. Construction follows once approved — with your contractor or ours.
