[Update March 16, 2017] If any of you tried to watch the lecture live on YouTube, I understand there were some technical difficulties.  The BGA even issued an appology via email.  But you can still watch the recorded version.  See below. [/Update]

Prof. Eduardo Alonso from UPC in Barcelona will be presenting this year's Ranking Lecture awarded by the British Geotechnical Association. You can live stream the lecture on YouTube starting at 1:25pm Eastern on Wednesday, March 15. Prof. Alonso will be presenting on the topic: Triggering and Motion of Landslides.

Mercator map projection

RockWare, the makers of RockWorks and LogPlot geotechnical software, have released a free online tool to convert between different coordinate systems. You can convert to and from State Plane coordinates using a NAD27 datum, and geographic latitude and longitude with a NAD83 / WGS84 datum using a pretty simple interface. There are probably a few other coordinate systems built in there as well. You can visualize your points immediately on a Google Maps interface. You can also plot up an elevation profile if you like.

Donald Trump

The U.S. has entered into the Trump era, so what does that mean for those in our profession? This blog post is an apolitical look at the economic outlook for infrastructure spending as it pertains to geotechnical engineers and the foundation drilling industry. Worth a quick read.

Businessman shows success concepts

The Geoprofessional Business Association (GBA) has announced a new course offering for its members, Geoprofessional Operational Leadership Development (GOLD) Course. This course is targeted at new and emerging leaders, group leaders, office managers, regional managers, and business unit leaders in the AE industry. It will contain specific instruction on operational aspects of the typical Geoprofessional business. The GBA has partnered with the McMahon|Siegel Group for the course, one of the instructors is former Kleinfelder CEO, Bill Siegel (see Bill's article on GeoPrac).

Paper on Underwater Noise Reduction of Marine Pile Driving PDF Print E-mail

Marine pile driving

Impact pile driving of steel piles in aquatic environments produces extremely high underwater sound levels. To address this problem, a double-walled pile has been developed to decrease the total noise transmitted into the water and substrate. The double-walled pile consists of two concentric steel pipe piles flexibly connected by a special driving shoe, allowing for an air gap between the two tubes. The double-walled pile is driven into the sediment by using traditional equipment that strikes the inner pile only. The air gap between the inner and outer pile and the flexible coupling prevent the radial deformation wave produced by the pile hammer from interacting with the water and the sediment. A second full-scale test of the double-walled pile technology was performed at Vashon Island, Puget Sound, Washington. A potential reduction of the peak pressure in excess of 17dB was observed for the double pile and of 16 dB for the mandrel pile. Root mean square (RMS) levels and cumulative sound exposure levels (SEL) decreased by 13 dB and 12 dB, respectively. Use of the WSDOT Geotechnical Design Manual Pile Driving Formula showed that the pile capacity of the novel piles was comparable to that of a control pile with the same outer diameter. PDA (Pile Driving Analyzer) data were also collected from both the inner and outer piles of the mandrel and double piles and will be used to modify current software for predicting drivability and stresses in the piles (WEAP (Wave Analysis of Pile Driving) analysis) and for estimating load capacity after driving (CAPWAP (Case Pile Wave Analysis Program) analysis).

Suzanne Lacasse, NGI, the 2015 Rankine Lecturer

The Rankine lecture is one of the most prestigious invited lectures in all of geotechnical engineering. The Institute of Civil Engineers has a list of all of the Rankine lecturers and links to most of their lecture papers which are published in Géotechnique. As far as I can tell, you still need to have access to Géotechnique's journals to view them, but at least this is a nice central list of all of the papers and past lecturers.
