Geotechnical Engineering

HDL’s Geotechnical Services Group brings a wide range of expertise to assist clients with soil and groundwater challenges. We provide out-of-the-box solutions and have successfully used multiple techniques to solve challenges throughout the State.

We pioneered the use of dynamic compaction in Alaska as well as the use of large-diameter helical piers in frozen soils for wind turbine foundations. We routinely develop design solutions with an understanding of future climate changes and how these changes may impact the design life of structures. We address challenges with a pragmatic and practical approach to assure our clients are getting exceptional value.
