I am very happy to see the efforts to educate owners using SRWs. The article in Geosynthetics (“Challenges in building SRWs … “ October/November 2007) is very good. I like the emphasis on quality control and defining responsibility of sub-surface improvements. It is a good checklist for things to be done. I believe this article […]

I think your conclusion that the owner should take control of the design is right on the money and should be part of the bid package. I also believe that a generic, performance-based design can be put forth as […]
