Wagman completed the construction of the I-95 HOV/HOT Lanes Post and Panel
Wall in Springfield, VA. This wall was designed and installed to provide slope
stabilization between a residential neighborhood and the I-95/I-395 interchange.
Wagman installed 155 global stability drilled shafts for the wall and slope
stabilization. Wagman utilized our Lo-Drill to drill and place 24” and 36” diameter
drilled shafts for H-Piles. Drilled shaft depths ranged from 35 linear feet to 45
linear feet. Steel H-piles were placed and aligned in each shaft prior to pouring
concrete. Wagman provided the design and engineering for permanent tiebacks
on the wall. Wagman’s equipment and expertise in design and construction of
anchored earth structures were essential to complete this project.
