ADAMA Software has released update 13.1 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of August 30, 2011. Some of the design methodology changes in the 2009 FHWA manual for MSE walls were implemented in Update 13, as well as a few corrections related to true bridge abutments and other bug fixes.
So, you’ve landed a job as a Geotechnical Engineer. What now? We all know that before performing any site investigation it is prudent to gather as much information that you can about the project site. There are so many resources out there that can help us get an idea of what the subsurface conditions are so that we can select the appropriate subsurface exploration techniques.
Below is a list of extremely useful sites that can help you gain some indication as to what the subsurface conditions are before planning the subsurface exploration program.

This summer, the National Concrete Masonry Association (NCMA) will release the third edition of its Design Manual for Segmental Retaining Walls (DMSRW) along with SRWall 4.0 software for the design of segmental retaining walls. SRW walls with higher wall heights often make use of geotextile or geogrid reinforcement putting them in the category of mechanically stabilized earth retaining walls or MSE Walls. The first edition of the manual was published in 1993 and is routinely used for everything from landscaping walls to multi-tiered commercial and residential retaining walls. This summer is shaping up to be a busy one for those in the retaining wall business as the FHWA NHI 2009 MSE Wall Manual is set to be released around the same time frame as well. Read on for more info on the DMSRW. (Screen shot by Gabriela Mariscal from NCMA via CE News)
