FHWA Research Project: Post-Grouted Drilled Shafts

The FHWA is partnering with a virtual who’s-who of geotechnical engineers and contractors specializing in drilled shafts and grouting to perform a research project on post-grouting (aka base-grouting or tip-grouting) of drilled shafts. More details […]

A Geoengineer’s Christmas List 2010

Christmas PresentSo last year at this time, I gave Santa my geoengineer’s Christmas list, but apparently I wasn’t good enough to get everything.  I did get two things off my list, the new FHWA Drilled Shaft Manual, and the New FHWA MSE Wall Manual, but that’s about it.  That’s like getting pink bunny PJ’s as a kid! So over the last year, I tried to be REALLY good, and this year I’ll just let last year’s list roll over with two additions:

An iPad

This year’s hottest gift would be great for reading my growing library of geotechnical papers, manuals, reports and books in PDF format.  I like the iBook app on my iPhone, especially being able to highlight and make notes and bookmarks.  And you can read an eBook allright, but try reading a scanned PDF report or paper on that little screen, doesn’t work too well.  I like the idea of having my entire library of technical papers, books and reports available at my fingertips!

And the coolest goodie on my list, the one I really want… […]

FHWA NHI Manual: Drilled Shafts Construction Procedures and LRFD Design Methods

Cover of FHWA/NHI Manual 'Drilled Shafts: Construction Procedures and LRFD Design Methods' by Brown, Turner and

The FHWA has released for download a comprehensive update to the 1999 O’Neil and Reese manual “Drilled Shafts: Construction Procedures and Design Methods”, lovingly referred to in the industry as the “Brown Book” or the “Drilled Shaft Bible”.  This 2010 manual from the National Highway Institute (NHI) of the FHWA is entitled “Drilled Shafts: Construction Procedures Procedures and LRFD Design Methods” and was authored by Dan A. Brown, Ph.D, P.E. of Dan Brown and Associates, John P. Turner, Ph.D, P.E. of the University of Wyoming, and Raymond J. Castelli, P.E. From an FHWA Memo on the manual:

Distributed with this memorandum is the publication entitled "Drilled Shafts: Construction Procedures and LRFD Design Methods" (FHWA-NHI-10-016). This manual is the reference text used for the National Highway Institute (NHI) course numbered 132014 on Drilled Shafts. The publication will become the tenth in the series of geotechnical engineering guidelines called "Geotechnical Engineering Circulars." Geotechnical Engineering Circular (GEC) No. 10 is prepared as a significant revision and update to "Drilled Shafts: Construction Procedures and Design Methods" (FHWA IF-99-025), and reflects the standard of practice for the design, construction and inspection of these features. The guidance is developed following Load and Resistance Factor Design (LRFD) procedures and will enable engineers to identify and evaluate technical feasibility and potential applications. 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 materials specifications, construction monitoring, and contracting methods for Drilled Shafts.

New FHWA Manual on Spread Footings for Highway Structures

Selection of Spread Footings on Soils to Support Highway Bridge Structures Hot on the heals of the revised MSE Wall Manual, the FHWA has released another manual, this one on Spread Footings. Selection of Spread Footings on Soils to Support Highway Bridge Structures was authored by Naresh C. Samtani, PE, PhD, Edward A Nowatzki, PE, PhD and Dennis R. Mertz, PE, PhD. So what is this manual all about? I think the foreword by Scott Anderson, PE, PhD of the FHWA Resource Center says it best:
