Commercial Structural Engineering
Thornfield Consulting Corp is a commercial structural engineering firm. We focus on cold-formed steel (steel stud) framing, structural steel and steel connections, miscellaneous metals, masonry veneer support, pipe supports, and specialty structural components. We work with contractors, fabricators, architects, and developers throughout British Columbia and beyond and our team holds professional engineering registration in BC, Saskatchewan, Wisconsin, South Carolina, and Washington.
We bring technical precision to complex structural challenges. Our approach emphasizes constructability, clear documentation, practical design grounded in real conditions, and responsiveness to evolving project requirements. From pre-tender planning to field reviews, we’re an active part of your team—coordinating with trades, owners, and GCs, working through design questions, and representing your interests.
With over 185 projects completed and more than 35 active long-term clients, we’ve built our practice on technical rigor and genuine partnership. We deliver solutions that are not just correct on paper, but buildable and practical on site.
Exterior steel stud engineering for this Clinical Support and Research Centre, including panel lifting design and custom lifting lug development. We worked closely with the client, fabricator, and installer to support prefabricated wall panels, with a focus on constructability, lift sequencing, and site efficiency. Lifting and handling forces were treated as a primary design case, allowing panel geometry, connection detailing, and lug placement to be coordinated early. Rendering by Diamond Schmitt Architects.
Structural Steel, Overhead Lifting
Spreader Bar
Chilliwack, BC
Purpose-built lifting beam for an American facility, with the structural analysis carried out in accordance with ASME BTH-1:2023. Torsion was a governing design issue due to the lift geometry and load path, and it was explicitly analyzed. The design was developed using a combination of MapleFlow, RFEM 6, and bespoke Python notebooks to evaluate section properties, torsional response, load paths, and overall stability, resulting in a solution that is efficient, buildable, and clearly documented for fabrication and safe use.

Steel Stud and Ceilings
Broadway Subway Stations
Vancouver, BC
Structural design of steel stud systems for Vancouver's Broadway Subway project, which includes six stations. Given the scale and complexity, careful coordination with multiple consultants has been essential throughout construction.
Structural Steel
Structural Steel Frame for RF Chamber
Wisconsin, USA
This 70 by 30 by 16 foot steel frame was designed as an exo-skeleton to support the installation of a Radio Frequency Chamber to be installed in Wisconsin, USA. Members of our team are registered in several US states. This project required extremely close coordination with the RF chamber supplier to ensure exact fit and no penetrations into the chamber.
Steel Stud and Ceilings
PNE Amphitheatre
Vancouver, BC
Engineering for the steel stud systems on this landmark project. Initially retained by the general contractor for pricing drawings of the parapets forming the arch exterior, we were later brought on by the wall and ceiling contractor to complete engineering for the remainder of the project.

"Matthew was the engineer for my shop construction and was great to work with. I’ve since worked with him on one of my railing projects. Good decisions."
Marten KerkhoffOwner, Tenmar Contracting
"Matthew has been very professional and easy to communicate with. Looking forward to working together on more projects in the future."
Chilliwack Steel FabricatorLong-term Client
"We renovated our townhouse in Chilliwack and had some structural engineering considerations. After phoning around town, there were very few who were willing to take on such a small, one-off job. Matthew was ready and willing to help us out. I am very grateful to him for taking on our project, doing so quickly and affordably. I’m happy to say our renovations are complete, including removing walls and adding beams."
