Building the Infrastructure of Tomorrow

The EHRA Structures team takes pride in providing cost-effective solutions for complex structures by adopting a holistic approach at the beginning of every project. This is accomplished through continued collaboration with the client and other stakeholders along with developing a good quality product.

Our EHRA Structural team experience encompasses structural design and analysis for existing and new concrete and steel bridges (include major highways, multi-level interchanges, water crossings, and railroad grade separations), bridge load ratings, civil structures, retaining walls, culverts, headwalls, junction boxes, hydraulic weirs, pump stations, lift stations and wastewater treatment plants. Our team carefully evaluates the constructability aspect of any given structure by understanding its behavior under construction loads, as well as design loads and site conditions, during the analysis and design phase. We also provide construction phase services to the client for RFIs, submittal review and structural construction methods. We provide solutions in the area of retrofit and repair of structures.

The EHRA team performs feasibility studies for several structural projects on a continuous basis for our Public and Private Clients. These studies include alternatives focused on the functionality and safety of structures, as well as the lifecycle cost.

At EHRA we have several team members who hold the Envision Sustainability Professional Certification; hence, we put an emphasis on sustainability for all of our structural projects.
