Geotechnical Infrastructure/Foundation Engineering
Geosyntec provides nationally recognized expertise and specialized geotechnical and geological engineering (geoengineering) services to evaluate and improve the design and construction engineering properties of soil and rock foundations. Our geoengineering specialists form one of the leading practices in the United States. They are recognized for their ability to develop practical guidance, and efficient designs conducive to aggressive construction schedules commonly imposed by project economics.
Our geoengineering practice focuses on difficult and challenging sites where the development of dependable, cost-effective foundations, and other geostructural solutions are critical to the success of the project. Our practitioners accomplish this by establishing a thorough understanding of the project site, developing a technical framework for the project, and incorporating the critical non-engineering drivers such as schedule and project economics into the early stages of our planning.
Our geoengineering professionals have responded to the challenges of increasingly unfavorable site conditions by developing and applying sophisticated approaches to investigate and characterize sites; analyzing foundation behavior; altering the engineering characteristics of the soil and rock at a specific site through soil and rock improvement; and environmentally remediating sites. We implement these approaches so foundations and other subsurface structures can be constructed safely, adequately support the built environment, and withstand potential geohazards. Our geotechnical practitioners are fully familiar and experienced with the practical application of these tools. For example, when a client needed to develop a critical structure near Wilmington Harbor in Delaware, the client turned to Geosyntec to geotechnically engineer a practical, cost-effective solution. Our team developed an innovative foundation design and construction methodology for very soft and compressible foundation materials that included wick drains, embankment preloading, and mechanically stabilized earth walls. Our design saved the client nearly $100 million when compared to more traditional approaches proposed by others.
Our geoengineering practitioners distinguish themselves by rapid development of an appropriate understanding of the geologic and environmental history of a site, and using this knowledge to screen potential ground improvement and foundation technologies (wick drains, deep soil mixing, deep dynamic compaction, vibro-replacement, and surcharging) to identify the more dependable and cost-effective approaches. These screening-level studies become a basis for gathering optimized geotechnical information based on carefully considered analyses tempered with practical, hands-on experience sufficient to not only characterize the site, but also design dependable foundations. These attributes have been particularly beneficial to our petroleum and chemical industry clients who are currently undertaking large-scale capital projects in undeveloped areas. For example, Geosyntec is working with oil and gas interests on foundation design, off-shore reclamation, and underwater slope stability issues related to the development of a LNG trans-shipment facility on the coast of southwestern Africa.
