Ellis Square Parking Garage, Atlanta, Georgia
Geocomp identified extensive soft clay seams below the bottom of the excavation that were not considered
in the design of the excavation support system. Working together with the project team, Geocomp provided
geostructural modifications and instrumentation systems to complete the deep underground parking
structure with minimal additional damage to adjacent structures.
Willow Island Hydroelectric Project, Willow Island, West Virginia
Geocomp is providing engineering services during design and construction of a 2,400 ft long
cofferdam and 100 ft deep excavation for future construction of a new hydroelectric powerhouse on the Ohio River.
Additionally, Geocomp will provide and operate the real-time web-based monitoring and warning system to
be used during excavation for the powerhouse for measurement of settlement, horizontal
displacement, pore pressures, and tilt of the existing piers during the construction.
The Colony at White Pine Canyon, Park City, Utah
Geocomp is evaluating the condition of 72 mechanically stabilized earth retaining and
bridge abutment walls, some of which have failed prematurely. Investigations have focused on
establishing corrosion degradation rates of the welded wire reinforcement, to predict remaining wall
service life. Geocomp has overseen a total redesign and remediation of the walls that have failed or
are predicted to fail in the near future.
National Cooperative Highway Research Program (NCHRP), Leominster, Massachusetts
Geocomp designed and built four 30-ft high mechanically stabilized wall (MSE) that were constructed
to investigate the effects on performance of high fines content backfills. The system was automated
with data loggers and the instrumentation included strain gages, piezometers, extensometers, and
AMTS instruments monitoring the complete displacement patterns for the different wall faces, extensometers
in the retained wall and settlement plates. Results of this research will be recommendations to revise
AASHTO design standards to allow MSE walls to use backfills with higher fines content.
