As part of our comprehensive array of services to better serve our clients, Tighe & Bond maintains geotechnical engineering capabilities in house. We routinely design foundations for a wide variety of buildings, smokestacks, water tanks, silos and other structures in essentially all soil conditions. We have the expertise to handle every aspect of the design process from on-site supervision of the subsurface exploratory work to the preparation of biddable construction documents and construction observation. We recommend foundation types, bearing pressures, seismic parameters, and design ground improvements and deep foundations where required.
We have developed designs and construction methodologies to allow roadways, retaining walls and embankments to be built over weak and highly compressible foundation soils. Likewise, we've managed ground improvements to facilitate building construction in similar circumstances. We are fully proficient in the design of geotextile reinforcement for improving subgrade, slope or surficial stability.
