The American Society of Concrete Contractors Safety & Risk Management Council recognized members logging exemplary 2014 safety records during the ASCC annual conference in Dallas. The council educates contractors on all aspects of safety relating to concrete contracting and insurance matters, and provides oversight on publications and events.
W. Burr Bennett Awards for Safety Excellence went to specialty contractor Keystone Structural Concrete of Houston, and general contractor Barton Malow of Southfield, Mich. The awards are presented in partnership with CNA to contractors that place the highest priority on safety. Entries are judged on three years of performance indicators, values and trends; self-assessment checklist of company safety practices; and, detailed descriptions of safety plans and culture.
Additional awards based on 2014 incident rates were presented to general and specialty contractors in four categories. General contractors receiving the Outstanding Safety Achievement Award for the lowest incident rate were Walbridge of Detroit (> 500,000 work hours); Korte Construction of Highland, Ill. (110,000–500,000 work hours); and, California Engineering Contractors of Pleasanton (< 110,000 work hours). Specialty contractors receiving the Outstanding Safety Achievement Award were T.B. Penick & Sons of San Diego (> 200,000 work hours); Bass Commercial Concrete of Little Rock, Ark. (68,000–200,000 work hours); and, Albanelli Cement Contractors of Livonia, Mich. (< 68,000 work hours).
The council also presented 54 contractors awards for zero lost time due to accidents and the same number were recognized for having lowered their incident rate from the previous year; 71 contractors received certificates for achieving an incident rate below the national average. Three companies were recognized for outstanding fleet safety records: Citadel Contractors of Apex, N.C., 467,483 miles with zero accidents; Lloyd Concrete Services of Forest, Va., 950,000 miles; and, Jordan Foster Construction of El Paso, Texas, 2,314,000 miles.
Turner Construction Co. and the National Building Museum have named the Council on Tall Buildings and Urban Habitat (CTBUH) recipient of the 2015 Henry C. Turner Prize for Innovation in Construction. The general contracting giant established the prize—accompanied by a $25,000 honorarium—at the Washington, D.C., museum to recognize an advance or high achievement in the process of construction.
CTBUH was selected for its history of leadership in facilitating research and promoting education, plus contributions to the building industry, which has benefitted from the group’s work related to tall buildings and urban planning issues around the world. Chairman David Malott notes the council’s intention “to utilize the honorarium to conduct an audit of the cutting edge technologies across all fields that contribute to tall buildings. We will create a positional paper that would be of value to all our membership, especially tall building developers who always want to know what the latest technologies are in each field.”
CTBUH is widely known for its role as the arbiter of what constitutes a tall building, a role that has grown increasingly prominent with the rise of supertall and megatall projects. In addition, the council has created an international community of industry professionals—developers, architects, engineers, builders, urban planners and environmentalists—and affording them such resources as a robust technical paper, video, and building information database. Through publications, best practices, and other materials developed by scientists, engineers and thought leaders on nearly every aspect of tall building construction, the council has established itself as the industry’s resource when it comes to planning, designing, constructing and maintaining increasingly sophisticated and complex tall, supertall and megatall structures.
Members of the H.C. Turner Prize jury are Skidmore, Owings & Merrill Chairman Emeritus David Childs; Turner Construction Vice President Chris McFadden and past President Hal Parmalee; and, Engineering News-Record Editor-in-Chief Jan Tuchman. Turner Construction CEO Peter Davoren and National Building Museum President Chase Rynd were set to present the prize during the late-October CTBUH International Conference in New York City.
Missouri University of Science and Technology (Rolla) Assistant Professor of Electrical and Computer Engineering Dr. Kristen Donnell is pioneering a nondestructive testing method for concrete structures using microwave energy. The active microwave thermograph (AMT) highlights flaws that could compromise safety or effectiveness; it works by using microwave energy to heat a defined section of material, which is looked at using infrared thermography imaging.
Donnell, who earned her master of science and Ph.D. degrees in electrical engineering from Missouri S&T in 2003 and 2010, respectively, began working on AMT about two years ago. She uses a 1- to 20-GHz high-frequency horn antenna to heat objects then view them with an infrared sensor that relays data to a computer. Because the heat burst lasts only a few seconds, her method reduces the risk of damage when using traditional flash heat lamps. AMT is also able to focus the heat at a predetermined depth instead of heating the whole object. When using a flash heat lamp to look at a problem in a wall, for example, the whole wall would need to be heated; in contrast, the AMT method focuses heat on only a small section. It’s not exactly an X-ray, Donnell observes, “but it does allow us to look inside the interior of a structure to show defects or problems.”
In the lab, she can set the AMT device to focus on the middle of a 4-in. concrete section. When the images are produced on a computer, they can show if the rebar is compromised (rusted, corroded, broken) or still in good working order. She also can look at the concrete for cracks or other weakening defects. Donnell also can use AMT to look at materials that are wrapped in carbon fiber, verifying adhesion at point that aren’t properly bonded. Testing of the method will continue with a long-term view of AMT commercial prospects in concrete.
