For over a decade, HEB Engineers has participated in the NH Road Agents Association ‘Mountain of Demonstrations’ event. It is an opportunity to meet municipal public works staff from around the state and get a look at new technology. As part of the event, HEB’s staff get together to design and build a small bridge which is loaded with concrete blocks and ‘broken’. Every year, visitors to our booth guess how much weight the bridge will hold before it breaks and the lucky winner goes home with a Cabela’s gift certificate. This year’s bridge, designed by John Ahern, Junior Structural Engineer, was loaded with half a pallet of block before it broke at 1,950 pounds.
