JTFAP Document Will Affect Every Geotechnical Engineer and Engineering Geologist

image A document entitled “Engineering and Geology Practice Guidelines” has been prepared by the JTFAP or Joint Task Force on Areas of Practice. The JFTAP was comprised of representatives from The American Institute of Professional Geologists (AIPG), the Association of Environmental and Engineering Geologists (AEG) and the Geo-Institute (G-I) of the American Society of Civil Engineers (ASCE). A draft of the document was published in February of 2009 and members of AEG have already been providing comments to their board through the Section Chairs for possible revisions to the document or for opinions on whether or not AEG should adopt it. A recent email to AEG Members from the President of AEG, Mark Molinari, indicates that the G-I has released the document to their membership for review and comments. Read on for more info.

Photo by Bharat Khandel, ADOT by way of NCS Consultants, LLCIn this part 2 of 2, various types of retaining walls are examined as possible alternatives in a side-hill retaining wall situation. These include conventional wall types such as CIP walls, MSE walls, gravity walls and soldier pile walls and some less conventional approaches such as lighweight concrete fill, hybrid soil-nail and geofoam wall systems, ground improvement and micropile walls.

Part 1 of this Side Hill Retaining Wall article covered the definition, significance, problems and failure modes, investigation techniques, analysis, and construction considerations of side hill walls.
