Book available on civil engineering failures

The American Society of Civil Engineers announces availability of Failure Case Studies in Civil Engineering: Structures, Foundations, and the Geoenvironment, Second Edition. This 155-page book provides short descriptions of 50 real-world examples of constructed works that did not perform as intended. Each case study contains a brief summary, lessons learned and references to key sources.

This new edition replaces the 1995 book. It contains eight examples of embankment, dam and slope failures, including St. Francis Dam in 1928, Malpasset Dam in 1959, Vajont Dam in 1963, Lower San Fernando Dam in 1971 and Teton Dam in 1976. It also discusses foundation, geoenvironmental, bridge and building failures.

– The book can be purchased for $45 for ASCE members or $60 for non-members at www.asce.org/Product.aspx?ID=23622321871&ProductID=175479320.

Kleinfelder honored for work on Snoqualmie Falls project

Kleinfelder received the Gold Award for Social, Economic and Sustainable Development from the American Council of Engineering Companies, Washington Chapter for its work in redeveloping the Snoqualmie Falls hydro project. The architecture, engineering and science firm said it won the award for “demonstrating advanced technical expertise” throughout the three-year project, which included the renovation of two powerhouses, preservation of six historical buildings and development of recreational site enhancements.

Plant 1 of the Puget Sound Energy-owned project was opened in 1898, at which time it was the world’s first completely underground powerhouse. Plant 2 was opened in 1910 along the Snoqualmie River below the falls.

“Kleinfelder was enthusiastic to work on this project because of its complexity, diverse construction techniques and commitments to the historic power plant and the surrounding environment,” says Rick Della, senior project manager. “For PSE, the challenge was to ensure that the plant continued to provide clean, renewable power, protect the historic structures and ensure that visitors can enjoy the falls and surrounding environment while meeting an accelerated 36-month schedule.”

The project reopened in April 2013 with a total installed capacity increase to 54 MW, up from 44 MW. For more information on this project, see the article on page 30.

EIA state profiles and energy estimates include hydro

The U.S. Energy Information Administration has included renewables, such as hydropower, in the state profiles and energy estimates on its website State Energy Portal at www.eia.gov/state.

For example, clicking on Oklahoma, which was updated in December 2013, users can see a map with the location of all generating facilities, including hydropower. Clicking on a plant icon reveals such details as its name, owner and capacity.

A chart of energy consumption by source reveals that only a small portion came from hydroelectric power in 2011 (the most recent information available).

A state energy profile provides:

– Quick facts, such as state rank in crude oil production and wind generation, as well as natural gas production;

– Energy consumption estimates by trillion Btu for coal, natural gas, motor gasoline, distillate fuel oil, jet fuel, LPG, residual fuel, other petroleum, nuclear electric power, hydroelectric power, biomass and other renewables; and

– Economic date, including population and employment; prices for electricity, petroleum, coal and natural gas; reserves and supply; distribution and marketing; and consumption and expenditures.

Hanula named to advisory board at school of engineering

John Joseph Hanula, vice president of CH2M HILL, has been appointed to the Sonny Astani Department of Civil and Environmental Engineering Advisory Board at the University of Southern California Viterbi School of Engineering.

The advisory boards were established to advocate for the school, advise the chairs of each department, and support the overall vision of the university’s engineering programs. Hanula, a civil engineer, will provide insight on the role of private sector consultants and how engineering disciplines are addressing infrastructure issues, CH2M HILL says.

The Viterbi School of Engineering enrolls more than 5,000 undergraduate and graduate students.


Bearing manufacturer Kingsbury Inc. has broken ground on a 33,000-square-foot facility in California for the repair and service of fluid-film babbitted bearings. The plant will provide support for Kingsbury’s clients west of the Mississippi River.
