Additional Foundation Projects

Project Description

Principle geotechnical design engineer for the long Badger Road overpass. The structure, approximately 40 m long, is supported on mechanically stabilized earth abutments. The design effort included planning and carrying out the field exploration with thermal measurements, laboratory testing, seismic assessment, assessment of foundation alternatives and retaining wall design.

Project Description

Senior peer reviewer for the geotechnical subsurface investigation and design for the preliminary I-15 Design/Build corridor project. The program included a study to estimate settlement for 54 bridge embankments over a 17.4 mile section of rigid pavement. A manual was developed that included guidance on pile foundations, embankment stability, embankment settlement, retaining wall/mechanically stabilized earth wall design, liquefaction and lateral displacements and instrumentation types and frequencies. Liquefaction assessment guidelines were also provided.

Project Description

Lead geotechnical consultant for a study to modify bridge structure to mitigate potential flood damage. Directed subsurface investigation and the assessment of the existing pile foundation to sustain lateral seismic induced loads. Impacts due to liquefaction and scour were also quantified.

Project Description

In order to reduce the potential of significant damage or collapse of the suspension spans an assessment was performed to identify elements of the suspension bridge that could be vulnerable to terrorist attacks and to develop measures to provide enhanced resistance to such incidents. The effort included the development of a threat scenario, a vulnerability assessment to potential blast and fragmentation damage, and the design of mitigation measures for the main tower and suspension cables against the design threat.
