Engineering and Design. Guidelines on Ground Improvement for Structures and Facilities

The purpose of this Engineer Technical Letter (ETL) is to provide guidance on ground improvement for USACE civil works and military programs projects. The enclosed document (Appendix A) contains an up-to-date overview of ground improvement techniques and related considerations. It addresses general evaluation of site and soil conditions, selection of improvement methods, preliminary cost estimating, design, construction, and performance evaluation for ground improvement. This document should be used as a resource during planning, design, and construction for new projects as well as a reference to guide more detailed design efforts for modification of our aging inventory of existing projects, particularly embankment dams. The use of such state-of-the- practice techniques is in keeping with good engineering practice and provides better service to our customers in concert with the USACE Strategic Vision.Corps of Engineers Washington DC is the author of 'Engineering and Design.
