Contribute to our Industry: Grand Challenges in Earth Retaining Structures One of the action items that came from the ASCE/G-I Earth Retaining Structures Committee conference call on 09 July 2013 was the need to identify the “Grand Challenge” issues within the field of earth retention systems. Grand Challenge issues are those issues that are transformational in nature. These are issues that if addressed, will have a significant impact on the current approaches to the design a

Is it a structure or is it earth? We recently conducted a poll in LinkedIn on the perception of structural engineers on earth retaining structures. In this poll almost 50% of the responding “structural” engineers felt comfortable designing any type of an earth retaining structure. Only 5% passed such work to a geotechnical engineer, while 9% voted as being involved in shallow basement walls. 34% voted that they sometimes are involved in designing earth retaining structures: W

Support of Excavation Software – Where We Are and Where We Are Heading I am really excited about presenting at the DFI-CSCE 18th Annual Geotechnical Seminar: State of the Art in Performance Monitoring and Computer Applications in Geotechnical Engineering. Four Points by Sheraton, Meriden, CT This annual geotechnical seminar is presented jointly by DFI and Connecticut Society of Civil Engineers geotechnical committee. We use computers and technology every day in engineering pr

Determine soil parameters when you don't have all the data. Geotechnical uncertainty is a major issue in deep excavation and geotechnical design. Minimizing uncertainty and estimating design soil property presents a major challenge to engineers. Most projects have only SPT test data, and different methods can result in widely varying strength estimates. Reviewers often ask for justification of estimated soil strength parameters, so how does one meet these challenges? In DeepE

2014 has seen considerable improvement in geotechnical construction activities within the United States. Big metropolitan cities, such as New York, Los Angeles, San Francisco, Miami, and Seattle have seen an expansion of luxury residential construction. 2014 also saw the one of the best years for commercial projects since 2009. We expect this trend to continue in 2015, and will put a strain on companies looking for engineering professionals to staff job sites. Infrastructure

Lateral surcharges from railway on temporary retaining walls Discussing earth retaining wall design issues with transportation or railway authorities sometimes feels like talking to a wall. Transportation officials basically have their hands tied by code or design manual, even when the code is taken out of context. An example of such case is the AREMA manual specifications for lateral surcharges on retaining walls. Most times the specifications are taken out of theoretical co

The best job in the world is a deep excavation engineer! The best job in the world is a deep excavation engineer. My 2.5 year old son loves Peppa Pig with the biggest muddy puddle in the world. His face fills with happiness when he spells out "Muddy Puddle". A few days ago, I described to him that daddy designs "very big Muddy Puddles". Thus for most kids we have the best job in the world. As deep excavation engineers though, we make the biggest muddy puddles in the world saf

Once you have finalized your sheet pile design you will need to order the appropriate sheet pile sections. In most cases, the original sheet piles can be replaced with an equivalent steel sheet pile sections. When this takes place, as engineers we are looking to provide equivalent strength and stiffness. Sheet pile walls will be formed by driving sheet sections and using proper connectors at corners. Sheet pile sections are available only in the US. Do you want to see if you
