FHWA Releases GEC 12 - Design and Construction of Driven Pile Foundations PDF Print E-mail

Pile driving on the west side approach of the W. R. Bennett bridge in Kelowna, British Columbia, Canada, June 2006

The FHWA recently released 'GEC 12 - Design and Construction of Driven Pile Foundations' (FHWA-NHI-16-009 and FHWA-NHI-16-010). A companion publication 'Design and Construction of Driven Pile Foundations - Comprehensive Design Examples' (FHWA-NHI-16-064) is also available. This publication replaces the previous Reference Manual titled Design and Construction of Driven Pile Foundations, published in April 2006. The publications become the twelfth in the series of geotechnical engineering guidelines called 'Geotechnical Engineering Circulars.'

This update reflects the state of the practice for the design, construction and inspection of driven pile foundations for transportation structures. The guidance is developed following the AASHTO LRFD Bridge Design Specifications, 7th Edition, 2014 with 2015 Interim, and Construction Specifications, 3rd Edition, 2010, with '11, '12, '13, '14, and '15 Interims. The text is developed with a sufficiently broad scope to be of value to a wide range of transportation specialists responsible for assisting with selection, design, development of specifications, construction monitoring, and contracting methods for driven piles.

New Zealand road damaged by fault rupture

Significant destruction has occurred in New Zealand as a result of a 7.8 magnitude earthquake near the town of Kaikoura, about 2 hours drive north of Christchurch. Video footage shows significant surface rupture causing damage to homes and infrastructure. There have been numerous landslides as well. The town of Kaikoura had to be evacuated, including about 1,000 tourists, after it was left without power by the event. Only two casualties have been reported based on the information I have heard, and it's fortunate there was not more loss of life. [Source: CNN.com. Image: Mirror.co.uk]

Eurofins Case Study: ESdat Online and ESdat Lab Portal

ESdat OnlineThe Eurofins Field Services Groundwater team conducts compliance monitoring on behalf of various Victorian Landfill operators.

New analytical results from the Eurofins lab and secondary labs were combined into spreadsheets containing ongoing and historical data on behalf of the landfill operators. This was a time consuming, labour intensive process. Uncontrolled, 'hand-me-down' spreadsheets can also introduce or hide critical errors.

Eurofins has adopted ESdat Online and the ESdat Lab Portal to replace the historic spreadsheets in order to increase efficiency and accuracy, and provide the landfill operators with direct access to their consolidated historical results through a web interface.

Example of a pre-fabricated retaining wall system that would need approval to be used by Ohio DOT

The Ohio DOT Division of Engineering, Office of Geotechnical Engineering, has a new procedure for pre-approval of prefabricated retaining wall systems (PWRS). In an announcement from back in April, they indicate that all wall system vendors will need to provide a detailed submittal for review and approval by ODOT. Those systems that are successful at getting on the approved products list will have to re-apply every 5 years. And all of the existing systems on the list that were approved prior to April will need to re-submit for approval since their status on the list will expire at the end of 2016. [Source: Ohio DOT OGE.

Screen shot of new load test software from Deep Excavation, LLC

Geotechnical software company, Deep Excavation, LLC has just announced a new software product for design of deep foundations. The product page for DeepFND notes that it brings together geotechnical design and structural design of deep foundations in one complete package. It includes both axial and lateral analysis of a variety of deep foundations, including drilled shafts, driven piles of various types, continuous flight auger piles (CFA Piles), micropiles, and even helical piles (if you opt for the premium version). Something quite unique is the fact that they have included the ability to interpret and process load test data. I look forward to taking advantage of the free trial to give this program a try. It is priced pretty reasonably, starting at $900 (US). [Source: Check out the DeepFND Page at Deep Excavation's website. Image: Courtesy of Deep Excavation, LLC]
