Keynetix are delighted to have been offered the opportunity to be a regular contributor to the Geotechnical Academy starting in June 2014.
The Geotechnical Academy is a collaboration between Equipe Group and Geotechnical Engineering Ltd, providing fundamental technical and commercial training to aspiring geo-professionals, helping them to apply their theoretical and technical understanding in the practical and commercial world.
The training experience is different from other more traditional offerings, in that it will take a group of delegates and their sponsors on a journey over a whole year, to greater knowledge and appreciation of their subject.
Roger Chandler of Keynetix will be taking part in the training sessions that will form part of this fantastic academy. Here he will be raising awareness in the industry of the importance of Geotechnical Data Management, AGS, BIM and the new BS 8574.
“The Geotechnical Academy is a great opportunity for both new and experienced engineers and it is great to be able to contribute to one of the modules.” says Roger “Good geotechnical data management is vital in today’s workplace and I find teaching this to engineers very enjoyable and rewarding. I’m looking forward to helping engineers experience some exciting light bulb moments over the coming months and then giving them practical advice on how to make better use of their time and geotechnical data.”
Roger comes from a Geotechnical background and has been an active member of the AGS Data Management Committee since 1997, a member of DIGGS Cone SIG since 2005 and was the co-author of AGSM.
Liz Withington of The Geotechnical Academy says “This is on-the-ground practical development for early stage career geo-professionals. The Geotechnical Academy is a partnership between Geotechnical Engineering Ltd & Equipe Training, providing unique, high quality vocational geotechnical CPD development for early career engineering professionals. We are delighted to have Roger Chandler from Keynetix as a regular contributor. Rogers’s innovative approach to geotechnical data management demonstrates The Geotechnical Academy’s commitment to challenging young geo-professionals in to stimulating change within the industry“
Attendees of the academy will gain knowledge, join in practical demonstrations of equipment and techniques, take part in discussion about a wide variety of technical and commercial topics relevant to their work and hopefully have a thoroughly enjoyable experience to inspire them into the future! All training days will be eligible for CPD certification.
A massive mudslide approximately 1 mile by 3 miles by 250 feet deep has occured in Western Colorado over the Memorial Day weekend. There are reports that 3 men from the nearby Collbran/Mesa area are missing. According to the Forbes article, the estimates of the size would make it three times the size of the catastrophic Oso landslide in Washington. [Source: Forbes via @CanGeotechJournal.

This is a different perspective on landslides than what I usually blog about on GeoPrac. This banking and insurance website blog post discusses what should and shouldn't be covered on a car owner's insurance policy. Several cars parked along the road were damaged after a retaining wall / slope failure in Baltimore last month. [Source: Read the blog post at Bankrate, Inc.. Image: CBS Baltimore]
The WSDOT announced recently that the Seattle Tunnel Partners Joint Venture has requested a total of $188 million in change orders so far, and that the Department has denied $157 million of those, with $31 million worth still under review. Among the change orders rejected was one for $125 million plus additional contract time because STP claimed the Bertha TBM was damaged by a steel well casing. WSDOT's position is that the location of the well casing was included in the contract documents. [Source: WSDOT. Image: Seattle Times Blog]
The primary deliverable of the project and the subject of this review is Geotechtools.org, a web-based tool for geotechnical engineers, structural engineers and pavement engineers. This website is a “toolkit of geotechnical information to address all phases of decision making from planning to design to construction.” What does that mean exactly? Great question. In this article I will give you an overview of the site and its resources and how it might help you on your next project.
The American Society for Testing and Materials, or ASTM, No. 57 stone is often used as sub base fill material below road surfaces and buildings. It is a fragmented stone with angular edges and is regularly utilized as a drainage layer when used with geotextile fabric. Although the material is touted by many as "self-compacting," excess voids left from zero compactive effort in locations with little confinement may not eliminate the possibility of future settlement. What happens when the environment above the No. 57 stone causes it to settle?
[Editor] Read on for the answer to this interesting question in the case of settlement of a structure at the University of North Carolina at Chapel Hill. The contributed article by Katherine Witt describes how URETEK Mid-Atlantic used their high-density polyurethane resin to stabilize the No. 57 stone beneath a settled foundation as well as lift the surrounding slab back into place.

A dramatic retaining wall failure and subsequent landslide last week damaged several cars and shut down a rail line in Baltimore, Maryland. The final failure was caught on video by a bystander. The landslide forced a number of residents to be evacuated from their homes.
Former Hayward Baker Vice President Joseph Welsh received the ASCE Opal Award for his 'lifetime accomplishments of noteworthy advancements in construction, and the many contributions he provided the civil engineering industry over the past 50 years.' His bio on Hayward Baker's website is very impressive. Mr. Welsh has been involved in many high-profile geotechnical projects, including the Central Boston Artery Tunnel, and Malaysia Petronas Twin Towers.
His extensive list of achievements also includes assisting with the introduction of jet grouting, fracture grouting, fine grain cement, dynamic deep compaction, vibro displacement and replacement, the use of fabrics for concrete forming, and deep soil mixing techniques in the United States.
