Structural Engineering

The structural design of any building or facility requires evaluating the intended use of the building and considering details like floor loads, vibrations, seismic activity, equipment movement, the amount of required interior open space, and the spacing between columns. Our structural engineers address the client’s present needs as well as taking into account any future facility expansion. From there, LDG’s structural engineers work toward an optimal balance between technical function and economic impact. Additionally, LDG’s expertise with all types of building construction methods as well as pre-engineered metal buildings, tilt-up, modular, and pre-fabricated construction allows us to assist clients in selecting the construction method best suited for their schedule and budget.
