This year’s APT (Association of Preservation Technology) conference was held 10-14 October here in Ottawa. Student teams were invited to take part in the conference via the APT Preservation Engineering Student Design-Build Competition. The competition took place over 3 phases; (1) structural analysis and building condition assessment of a local masonry arch, (2) design, build and loading of a masonry arch on campus, (3) Design, build and load of a dry-stack arch and solving preservation problems while at the conference.

Eleven teams from across North America applied to the competition and 4 made it to the finals in Ottawa (Carleton, McGill, Willowbank, Nebraska). Teams were awarded points based on their arch’s load resistance, lightest weight and quickest build. Teams were also awarded points for the quality of responses to preservation related problems given by organizers while at the conference. In the end, Carleton’s team earned the most points and took home the trophy.

The Carleton team of engineers was lead by Michael Gutland (M.A.Sc Civil Engineering, NSERC CREATE Heritage Engineering Program) and included Abhijit Dhanda (M.A.Sc Civil Engineering, NSERC CREATE Heritage Engineering Program), Meghan Potts (M.Eng Civil Engineering), Ben Clark (4th year Civil Engineering), Yasmine Arshad (3rd year Civil Engineering), and Kathryn Chung (3rd year Architectural Conservation and Sustainability Engineering),
