GCSWall provides generic tech transfer programs for government and private sector groups at no cost. Please write asktheexperts@gcswall.com to arrange. These presentations take about an hour and can be shorter or longer, depending on need. Here is a summary topics that can be included in a workshop

The presentation is a summary of 40 years of geotechnical research in retaining walls, bridge abutments, open bottom box culverts, reinforced soils, soil nails, landslides and rockfall. This research was performed by Colorado DOT, the US Forest Service, the Federal Highway Administration and several agencies and universities. Several new tools, methods and techniques will be presented that are not as yet in standard practice. Earthquake Wings (a new and better way to build abutments in seismic regions) will be presented. Scour prevention methods will be introduced. The presentation concludes with recent constructions with the Soil Nail Launcher, including Launched Nails, Launched Micropiles and Launched Scour Micropiles.
