GEI is particularly strong in the performance of geotechnical investigations and providing construction observation and materials testing services for pipeline projects.  GEI is able to perform static and dynamic analyses to evaluate allowable soil pressures, total and differential settlements, lateral earth pressures, required pavement thickness, subsidence and fissure formation, soil collapse potential, erodibility of soils and sediment transport, uplift pressures, shoring design, slab support, pile capacity, soil liquefaction, seismic response spectra, slope stability, and slope deformation.  We are very familiar with both rigid and flexible pavement design and development of recommendations regarding site grading.  We also provide construction observation and management services as well as design and install instrumentation for monitoring structural performance.
