Structural Engineering

HSH is pre-qualified with MassDOT for bridge design and has experience designing structures from small culverts to multiple span stringer bridges with supporting foundations. Foundations can be shallow or deep foundations, including driven piles, micropiles, and drilled shafts.

HSH can provide our clients with a range of feasible solutions for small, medium, or large projects and can provide formal recommendations. We are experienced in taking bridge projects from concept or preliminary phases through final design and construction.

Our Structural Engineering group also has experience with retaining wall design and designing foundations for overhead signs and traffic signal span poles, including the development of contract documents. Walls can range from short landscape walls with minimal embedment to taller walls that require frost protection and borings.
