Geostructural Design Services

Local and national specialty geotechnical and tunnel contractors, as well as design professionals and facility owners call on Brierley Associates to design a wide array of support of excavation systems. Whether steel or timber sheeting systems, slurry walls, soil nails, jet grouting, deep soil mixing or, shaft and tunnel linings for initial and final ground support, we have the skill sets needed to evaluate subsurface conditions at your project site and develop constructible and cost effective support systems. Sometimes, adjoining buildings or underground infrastructure require protection during construction and demolition projects. Brierley Associates has designed a variety of geostructures that are suitable for both the facility requiring protection and ground conditions. Some of these techniques include hand dug piers, slant drilled piles, needle beams, micropiles, and jet grout treatment.

We are often asked, "What is Geostructural design?" In our view, this part of our practice is site specific and makes use of traditional empirical, hybrid empirical-structural, or numerical methods, depending on ground conditions and the complexity of the structure. Our engineers and geologists work together to evaluate how the ground will behave under a variety of conditions and phases of construction. Using a multi-faceted approach, we at Brierley Associates have designed underground structures that have successfully been constructed in all kinds of conditions, ranging from soft soil to hard rock, all over the country.

It is our responsiveness, value engineering capability, and technical skills that have contributed to close working relationships with repeat clients as we "Create Space Underground". Brierley Associates designs projects involving ...
