Bridging Advanced Structural Science with Practical, Site-Ready Engineering
At Sepco Consulting Engineers, we provide more than just drawings—we provide technical certainty. Based in Thornhill, and serving the Greater Toronto Area (GTA), our firm specializes in managing complex structural challenges for residential, commercial, and industrial sectors across Ontario.
The SEPCO Advantage: Principal-Led Engineering
Many firms delegate site reviews and critical assessments to junior staff. At Sepco, we believe high-stakes projects require senior-level judgment from day one.
Direct Accountability: Your site visits and technical assessments are conducted personally by our Principal Engineer, Dr. Reza Parsiavash, P.Eng., Ph.D., ensuring 20+ years of expertise is applied to every decision.
Technical Authority: Our leadership holds Ph.D.-level qualifications and is recognized as a Designated Consulting Engineer by Professional Engineers Ontario (PEO).
Constructability Focus: We prioritize "common sense" engineering. Our designs are optimized for real-world site conditions, ensuring they are straightforward for contractors to build and cost-effective for owners.
Comprehensive Structural Solutions
Our team delivers specialized expertise across a wide range of infrastructure and building types:
Residential Engineering: Custom luxury homes, renovations, and load-bearing wall removals compliant with the Ontario Building Code.
Commercial & Industrial: Specialized solutions for manufacturing plants, heavy machinery support, and cable tray systems.
Forensic & Assessment: Root-cause analysis of structural defects, settlement, and pre-purchase structural assessments for property buyers.
Specialized Infrastructure: Expertise in the design and evaluation of complex structural shoring, lateral excavation supports, and temporary works required for high-risk construction environments.
Our Commitment to Sustainability & Value
Sustainability at Sepco is a core engineering principle, not just a buzzword. We utilize advanced structural optimization to:
Reduce Material Waste: Precision engineering allows us to use exactly what is needed—no more, no less—minimizing the environmental footprint.
Lower Construction Costs: Efficient designs reduce material consumption and labor time, keeping projects within budget.
Ensure Durability: Every project is designed in accordance with the National Building Code of Canada (NBC) to stand the test of time.
