Learn more →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.
Consultation & scoping
A brief call or site visit to understand your project, zoning eligibility, and whether you need engineering-only or full design-build.
Zoning & bylaw review
We confirm what's permitted as-of-right and identify if a Committee of Adjustment application is needed before permits.
Design & engineering
Drawings prepared in-house by our team. All structural drawings stamped by Arash Bahamin, P.Eng.
Permits & construction
We submit permits and manage city communications. Construction follows once approved — with your contractor or ours.
Client reviews
What clients say about working with UTES
"Arash did an exceptional job helping us with drawings and obtaining the city's permit. He spent time with city engineers to understand their requirements and alter drawings to their satisfaction. Very knowledgeable and professional."
Kambiz
Permit & drawings — Toronto
"He took the time to understand our requirements and design priorities, prepared cost-effective solutions, and provided us with the facts so we could make informed design decisions. Our permit was approved faster than expected."
Richard Cheung
Design & permit — GTA
"Arash and his team took our concept and designed our garden suite to match our vision. They submitted all permits and were easy to communicate with every step of the way. Thanks for all the work with tree permits and guiding us through the challenges."
Bruce Laird
Garden suite — Toronto
"Hiring Arash as a structural engineer was a wise decision. His expertise ensured the structural integrity of our project, and attention to detail helped identify and address potential issues early on. Highly recommend."
