Collapse of Foundation Wall (August 2011)
Photos below show effects due to total collapse of long segment of block foundation wall supporting commercial building in Pennington NJ. Height of soil backfill against the wall had already exceeded standard limits such that the wall was already cracked. Water from tropical storm Irene saturated backfill, providing additional pressure that resulted in total collapse into basement.
Sidewalk collapsed downward as foundation wall collapsed inward.
View from inside basement, looking towards collapsed segment of block foundation wall.
Remaining walls around basement were also cracked and pushed inward, due to excessive height of soil backfill pushing against these walls.
Photos below, showing construction of a segmental concrete bridge in New Jersey, are for general interest. Design was performed by others for NJDOT. The bridge is now completed and open for traffic in both directions.
First half of new segmental concrete bridge over inlet to Shrewsbury River from Sandy Hook Bay, between Highlands and Sea Bright, New Jersey.
View is from top of hill below north tower of Twin Lights in Highlands.
The northbound bridge has now been completed, alongside the southbound bridge.
Looking north towards bridge under construction; August 2009.
Lower span is the former drawbridge which has since been removed.
