Every year contestant teams must create a 21-foot-long bridge for a specific hypothetical situation. This year’s scenario required a bridge to carry traffic over a scenic river in a state park. It had to be light and stiff without being visually intrusive, provide clearance for boats, and passageways for utility lines. Restrictions to protect wetlands during construction required the builders to sometimes work in inconvenient locations and limit the size of nearby supply depots.
Bridges are graded according to construction speed, lightness, economy (construction time and number of builders), efficiency (how well it resists deflection) and display (appearance and poster), resulting in a single overall score. As in real life, teams must constantly make tradeoffs such as deciding on a heavier design, which might result in lower scores in some categories but higher scores in others.
Co-captain Emily Moberg, a CEE senior and veteran of previous competitions, credited the team’s fine standing to a “relatively strong performance in all categories and lack of abysmal performance” in any single area. In several categories, she described MIT as “neck to neck with the schools around us. A few points better or worse would have shifted the order.”
