CONTRACTING FOR MECHANICALLY STABILIZED BACKFILL WALLS

The key differences in the mechanically stabilized backfill (MSB) walls available in the U.S. market are discussed, particularly with respect to their impact on the walls' stability and long-term performance. These differences are mainly in the soil-reinforcement interaction, the strength and stiffness of the reinforcement, the bond between soil and reinforcement, and the durability of the system. Other factors that make a difference include the strain compatibility between soil and reinforcement, the deformation characteristics of the backfill, and the aesthetic and environmental impacts of the facing. Contracting procedures for MSB wall projects are discussed, and lessons learned from case applications are highlighted with particular reference to contracting methods and economical benefits. A preferred method that would ensure low cost, speedy process, and minimum confrontation between the design engineer and the vendor is recommended.
