An innovative precast/prestressed concrete retaining wall system that minimized the number of different panels required and reduced panel and footing weight was used to shave four months off the construction schedule for this 4,000-ft retaining wall project. The new retaining wall system offers numerous advantages.
There are no special forms required to fabricate the segments. The segments are light and easy to transport. The ease of fabrication of the precast segments provides the opportunity for small precasters to bid on a project. The gap between the precast segments provides contractors with adequate tolerances for proper fit. The system is fast and easy to erect, improves work zone safety, can be used for curved alignments, and can handle multiple aesthetic options. Finally, sections of the retaining wall can be easily replaced in the future.
