|NIST Standards-in-Trade Workshop on Cement and Concrete for the Americas |
Several U.S.-based codes and standards developers, certifiers, and trade associations, together with the National Institute of Standards and Technology, will host approximately 25 representatives from six Latin American countries for a NIST Standards-in-Trade Workshop for the concrete and cement industry. Organizations such as ASTM, the American Concrete Institute, the International Code Council, the National Fire Protection Association, the Portland Cement Association and the National Ready-Mixed Concrete Association will join representatives from Argentina, Brazil, Chile, Colombia, Ecuador, and Mexico for the event. The workshop will take place Dec. 9-13 (during ASTMs December Committee Week) at the Fontainebleau Hotel in Miami Beach. The Standards in Trade Workshops are a major activity of the Global Standards and Information Program in the NIST Office of Standards Services.
This workshop will facilitate an exchange of timely information among private and public stakeholder representatives in the concrete and cement industry regarding U.S. and various Latin American national practices for the development of concrete and cement standards and codes and national regulatory and enforcement practices.
Educational sessions will include overviews of the various U.S.-based organizations and their work, presentations by the Latin American representatives regarding their respective national standards, code processes, and regulatory environments, observation of technical subcommittee sessions, and a field trip. A key component of the workshop is an open exchange on the potential benefits of and barriers to a unified approach to codes and standards. You are invited to join this discussion, which will take place on Wednesday, Dec. 11 from 11:00 am until 12:30 pm. Contact Jim Olshefsky, ASTM (phone: 610/832-9714) or Teresa Cendrowska, ASTM (phone: 610/832-9718).
ACI in Mongolia
Mongolia is the latest country to benefit from the American Concrete Institutes certification program. Eight Mongolian students have successfully passed certification testing for ACI Concrete Field Testing Technician Grade I. Two certification sessions were conducted over the past year, one in Mongolias capital city of Ulaanbaatar and the other in Darkhan. Armed with Mongolian-English dictionaries and Mongolian translations of the various ASTM standards covered during the sessions, M.R. Hansen, a professor at the South Dakota School of Mines and Technology, and his students worked through the material to successful completion of the certification exam. Hansen says that providing ACI certification in Mongolia will be an important step to improving the quality of concrete construction in the country.
Measurable Vibrations May Warn of Structural Collapses
Death and injury from collapsing walls or falling roofs are occupational hazards for firefighters and rescue workers. Vibration sensors that give early warning to building collapse could cut such risks significantly. Fire engineers from the National Institute of Standards and Technology and NIST-grantee Harvey Mudd College (Claremont, Calif.) have tested the ability of highly sensitive motion detectors to detect pre-collapse building vibrations at an abandoned shopping mall in Woodbridge, Va. The controlled fire tests examined the vibration characteristics of lightweight steel frame building construction, during fires large enough to cause collapse of steel deck roofs. The researchers hope to develop a methodology for interpreting the vibration data. A warning device that uses such technology could be attached to burning buildings or incorporated into building safety systems such as smoke detectors.

Decision Making in Urban and Civil Engineering
The 3rd International Conference on Decision Making in Urban and Civil Engineering (DMinUCE) will be held in London, Nov. 6-8, 2002. This conference addresses issues pertaining to decision making in many aspects and fields associated with the design, construction, maintenance and decommissioning of civil and building projects. It provides a medium for the exchange of ideas, thoughts and experiences to be shared by international researchers and practitioners from a diversity of disciplines within urban and civil engineering, and the built environment in general. The conference is organized around a series of symposia. For all inquiries relating to conference organization, contact the conference chair. See the Web site for information relating to the symposia and symposium leaders.
DoD Turns to Private Sector
The U.S. Department of Defense maintains a policy of selecting the best model code provisions and industry standards available for military construction use by all DoD divisions, and has recently turned to the private sector in selecting codes for its Unified Facilities Criteria (UFC). Following a multi-year review, the DoD's new guidance documentUFC 1-200-01, Design: General Building Requirementsincorporates important private sector standards into a single model building code for design and construction of all military projects. The DoD has utilized the standards and codes of several U.S. standards developing organizations in its UFC, including the American Society of Civil Engineers, ASTM International, the International Code Council, the National Fire Protection Association and the National Roofing and Contractors Association. While the military often requires higher standards in building projects and constructs some facilities that do not exist in the private sector, using private industry standards for DoD projects promotes communication in the marketplace, improves competition, and results in cost savings. The application of these private sector codes and standards in DoD projects reflects a continued commitment to keep military personnel as safe as possible whether on base or in the field.
CAESAR Project Releases New Human Body Measurement Data
Variation in the human form has far-reaching effects in industry and on standards; how we fit into and use vehicles, clothing, or equipment can be critical to our safety and well-being. The recently completed CAESAR (Civilian American and European Surface Anthropometry Resource) project reduces guesswork about body surface measurements, making it easier to use computer-aided design and rapid prototyping when making products that are dependent on accurate information about the size and shape of the human body. Managed by SAE International, the CAESAR project is a unique joint venture that brought together military and private sector interests from the apparel, aerospace, automotive and other industries. Using a three-dimensional body scanner, CAESAR generated surface data on 2,500 U.S. and 2,500 European civilian males and females ages 18-65 of various weights for scientists and engineers around the world, to revise current anthropometric databases.
Using a new data collection technology referred to as Three Dimensional (3-D) Surface Anthropometry, this project provides the first viable method for capturing 3-D data of subjects in realistic postures, and alleviates dependence on the subject's positioning when measured. SAE International has just released for sale the North American data set. Additional information is available from SAE International. //
