Designed and completed underpinning of two adjacent historic structures with over 200 jet grouted piles.
A series of inclined and vertical jet grouted underpinning piles 16 feet in length were installed. Columns
were constructed to fill voids below the existing wall footing and to stabilize loose foundation soils at
both a one-story electrical substation and two-story museum annex constructed in the 1880s.
