Geotechnical Engineering

Geotechnical Engineering

SYNGEN maintains experience on a wide range of geotechnical engineering projects in a number of climatic and geologic settings across Alaska and the Lower 48 states.

Sheet piles used to shore a deep excavation into stiff clays for pipeline excavation in Wisconsin.
The author conducting pile load tests (quick test) on timber piles driven into soft marine sediments in North Idaho.
An elevated, adjustable foundation system designed by the author. This foundation system is designed to eliminate heat transfer between the warm building floor and the non-thaw stable permafrost below and to be adjustable as natural thaw of permafrost and seasonal frost heave cause minor movement, over time.
The author shearing stiff clays to estimate the undrained shear strength of the materials in an unconfined compression strength test.
The author conducing a subsurace investigation for a facility near Seattle, Washington.
A clear ice deposit exposed in an excavation at a construction site near Fairbanks, Alaska.
The author conducting pullout tests on post tensioned anchors used to tie back soldier piles in a deep excavation in Tacoma, Washington.
One of the more infamous examples of the effects of non-thaw stable permafrost on heated foundations in the hills surrounding Fairbanks.
A core of nearly clear ground ice taken by the author from below an existing distressed warm foundation near Fairbanks, Alaska.
