The initial retaining wall analysis was performed by a national retaining wall company. Their design did not include a more rigorous global stability analysis which considers potential deep-seated, rotational failure surfaces outside of the tradition-al “reinforced soil zone”.
Earth Retention was contracted to perform an overall soil reinforcement design, which resulted in significantly longer geogrid lengths and an increased number of layers to stabilize the entire bluff.
Working closely with ACP, a large retaining wall installer in Florida, ERS was able to coordinate the stamped engineering, site supervision, and wall installation with the architect and general contractor. The result is a spectacular home, placed atop a fully geogrid-stabilized soil mass, with all required factors of safety. The result: an architecturally beautiful solution to a tough site, and a satisfied owner.
Compared to alternative designs and retaining wall types (big block walls, soil nailing, poured-in-place concrete walls), the ERS-designed segmental retaining wall (SRW) solution achieved cost savings of over 60%.
