We offer a complete range of structural engineering services including design and detailing of concrete and steel, structural inspection, and rehabilitation of structures.
As a support service to both internal projects and to other engineering firms, our structural engineers design diverse types of concrete and steel structures for facility rehabilitation and new sites. They design concrete masonry unit and steel control buildings, concrete pads, foundations, lift stations, and various concrete tanks. Concrete tank design is performed for an assortment of purposes and shapes including circular tanks, rectangular basins, and elevated splitter boxes.
Bridges and culverts built at a new location or as a full replacement for an existing structure require diligent investigation of a variety of issues including roadway widths, horizontal clear zones, structure type, and cost. The structural engineers at Costello perform detailed design work on bridges of both steel and concrete of varying beam and girder types. Additionally, Costello offers in-house hydraulic and hydrologic modeling for bridges over waterways. This is important since determining the size of hydraulic opening is critical to the design. All of this data is collectively used to design a bridge that is accurately suited to the site.
OUR STRUCTURAL ENGINEERS HAVE DESIGNED NUMEROUS TYPES OF STRUCTURES INCLUDING:
