The Quad Phase 2.jpg


QDA was established in 1979. Quinn Dressel Associates is widely recognised for its major buildings throughout North America, Europe, the Middle East and China.  We have earned the respect and recognition of our peers in the industry for consistent production of sound and creative designs of structural systems for an extensive range of building types.


Though relatively modest in size, we have a proven record of being able to undertake multiple, large-scale, and complex projects simultaneously. Our team has a wide range of experience working on both new construction, restoration & renovation builds. We have worked with all levels of government, institutions, banks, corporations, developers, and international and local architects. Our team approach is oriented to promote creativity, yielding optimum and often innovative solutions for our Clients. It is our talented team that allows us to proudly ensure the integrity and quality of all our designs.


At Quinn Dressel Associates we also take pride in the “hands-on” approach of our Partners, who, backed by their extensive collective experience, ensure the success of each and every project. The fundamental ideology of our firm is to provide our Clients with the best possible project, produced within budget and on schedule. It is our commitment to our Clients, to engineering, and to the science – and art – of building that has given us a reputation for excellence.
