H+O Structural Engineering

Where technical engineering meets practical design.

Hayes & O'Neill Structural Engineering is a full-service structural engineering firm offering design services for both new and existing construction. With diverse design and hands-on construction experience, we bring a NEW perspective to the design team – a perspective that has a REAL understanding of the construction logistics and cost impacts associated with each design decision. This perspective brings intangible value to our clients by addressing typically unforeseen challenges early in the construction process to prevent added costs and schedule delays. In addition to traditional design services, we are able to offer our clients a design-build service in collaboration with Rens Welding & Fabricating, Inc. This unique service allows our team to blend the structural engineering and steel detailing process to expedite project schedules. No matter the project size, this NEW perspective is a tremendous benefit to our clients and their projects. Hayes & O'Neill Structural Engineering has two office locations, (1) BOSTON's Fort Point neighborhood and (2) Taunton, MA allowing us to service projects throughout New England and the greater Boston area, including but not limited to Massachusetts, New Hampshire, and Rhode Island.
