The Inverness
Heights project site had been developed for a couple of years
and had a 11' high 1.5:1 slope that had been cut along the back
side of the property that was experiencing several localized surficial
failures. Soil was constantly sloughing off of the slope face
and falling down to the bottom of the slope where the roadway
and buildings were located. This presented a safety issue. During
this time, several attempts at mitigating the loss of soil had
been tried with no success. It was evident that the existing soils
in the cut slope were not stable. Gallet was hired by the current
owner to determine why the slope was failing and to propose a
repair that would address the issue with the surficial slope failures.
Gallet then brought in Synergy to help develop a solution that
would solve this problem once and for all. Synergy's experience
in the design and installation of soil reinforcement technologies
made them a logical choice for this project.
For the design,
Synergy was presented with an as-built of the existing slope that
required repairs as well as some geotechnical information for
Gallet. The final design for the repair consisted of five - 10'
high segmental block walls in a tiered configuration. Each wall
was set back 10' from the one beneath it. Synergy was responsible
for providing the final wall configuration and transitions at
the ends. The final layout resulted in approximately 30,000 sf
of wall. All of the walls were back filled with #57 stone. Production
of the walls exceeded 1,800 sf in a single day. The combination
of Synergy and Gallet led to a successful repair of the slope
stability problem at the site. The owner, tenants, and customers
feel safer now that an engineered solution had been provided.
The project was completed in the Summer of '07
