Challenges / Solutions

Significant grade fills of up to 16 feet and grade cuts of up to five feet required close evaluation of engineered fill placement. Significant challenges with poor subsurface conditions required the removal and replacement of soft/loose fill soils with engineered fill to support the foundations and floor slab, as well as, the removal and replacement of unsuitable organic soils within the retaining wall development area. In addition, a variety of subgrade stabilization techniques were used to minimize removal of non-organic native soils for support of engineered fill.

Smart. Results. Fast. 

With any design/build project, turnaround time on project deliverables is critical to meeting construction milestones. G2 performed this significant geotechnical investigation in a short period of time and provided preliminary design recommendations shortly after completion of the field report to allow the design/build team to move forward with their design.
