Final Compaction Notice October 8, 2019
On or about Tuesday October 8th, the developer of the area surrounding the NJT
Railway Station will start a process called Dynamic Compaction of the soils on the
site. This process is used to compact the existing soils below the surface to allow
for the installation of infrastructure and to ensure the construction of buildings is
on a stable and safe base.
This compaction will take place on the west portion of the site that was recently
cleared of brush and other debris and may take up to 8 weeks to complete. It is
expected that impact vibrations will be felt up to a 200-foot radius from the area.
The nearest properties are the NJT Railway Station at 300 to 400 feet distance and
the SOMA apartments at 400 to 500 feet away. Buildings on the east side of
South Bridge Street are approximately the same distance or more distant than the
location of SOMA. Vibrations will be continually monitored throughout the
process. The contractor is required to comply with the Borough and State of New
Jersey noise ordinances.

What is Dynamic Compaction?
Dynamic Compaction consists of the introduction of multiple passes of high
energy impacts at the ground surface by repeatedly dropping steel tampers
generally ranging from 6 to 20 tons from drop heights ranging from 30 to 60 feet.
The high energy impact creates a shock wave that densifies the soil at depth and
reduces the void ratio; thus, improving the consistency and overall engineering
properties of the soil mass. In doing so, the need for off-site removal of the
existing soils for replacement with compacted granular fill or the installation of
deep foundations which bypass the loose soils can be eliminated. (Source:
