PGC symposium offers valuable facts, data

Post Time:Nov 12,2013Classify:Industry NewsView:40

About 100 people attended the Annual Symposium by the Protective Glazing Council of Topeka, Kan., at the Crystal City Marriott, Arlington, Va., Nov. 28-29. Sessions were chock-full of information on the history as well as updates on codes and standards, insurance practices, and new products and trends in the market. Scott Haddock, president, PGC International, spoke on “PGC’s Direction and Future Strategy in the Industry.” “Incorporated in 1997 in Washington, D.C., PGC started as an adhoc advisory committee to address GSA’s need for protective glazing systems,” he said. The organization did a strategic assessment this year and decided to form a technical committee to “identify, review, evaluate and pursue projects of a technical nature that promote the advancement of protective glazing technologies, services and products,” Haddock said. The goals that came out of the assessment include: creation of a voluntary design guide for blast hazard mitigation systems; development of an American Institute of Architects accredited presentation; attend AIA and other tradeshows; establishment of an industry collaboration task group and identification of joint benefits; and boosting PGC visibility through increased press releases, publications and Web site improvements, Haddock said. David Hattis, co-founder, Building Technology Inc., Silver Spring, Md., talked about the history of standards including pre-ASTM, Standard Test E 1886 and Standard Specification E 1996, in his presentation “Hurricane and Windstorm Building Technology.” He also discussed internal pressurization that occurs during hurricanes. “Partially enclosed buildings have three times higher internal pressure coefficients than an enclosed building,” he said. Jeffrey Gould, senior engineering specialist, FM Approvals, Factory Mutual Global, Norwood, Mass., talked about the importance of windstorm resistant fenestration products in his presentation “The Insurance Industry and Hurricane Glazing.” It’s not the window or roof damage that costs money; it’s the building envelope damage that puts the insurance companies behind, he said. In his presentation, “New Research on Protective Glazing in Seismic Events,” Charles Eva, student at the University of California, San Diego, talked about the three primary variables of interest studied through in-plane seismic racking experiments of glass panel systems: aspect ratio, window film type, and attachment system and loading protocol. The student team conducted monotonic and crescendo tests on annealed ?-inch thick glass, typical of midrise storefront window details, to determine baseline performance. Jaime Gascon, chief of product control division, Miami-Dade County Building Code Compliance Department, talked about “2007 Hurricane Code Cycle review.” He outlined the key differences between the High Velocity Hurricane Zone and the Non-HVHZ sections of the Florida Building Code and essential changes that will be part of the 2007 FBC. He also discussed weaknesses exposed by the recent hurricanes and the code language approved for the 2007 FBC. “A new section in chapter 24 of the FBC will require that the exterior lite of glass in an insulating glass unit be safety glass,” he said. “Exceptions being large missile impact resistant glazed assemblies and non-impact units protected with shutters.” Lt. Patrick Devlin, NYPD Counterterrorism Division, discussed the various counter-terrorism initiatives and programs of the New York City Police Department in his presentation, “Threat and Risk Assessment.” He described his division’s work with the city’s major construction and redevelopment projects, such as the Freedom Tower, and the effort of having security elements built into them. “Up until six years ago, I didn’t have any interest in glazing, fenestration and things of that nature,” he said. “After 9/11, I wanted to learn about this. William Veys, PE, Protective Design Center, Omaha, Neb., Army Corps of Engineers, followed Lt. Devlin with his presentation “United Facilities Criteria update.” He talked about the background and updates of the UFC, specifically the glazing, framing, bite, connection and supporting element provisions required by Standard 10 that deals with glazing requirements of windows and skylights. “UFC uses hazard descriptions as provided by definitions in ASTM F1642,” he said. “Design to resist a blast load without glazing fracture is cost prohibitive. Therefore, the design philosophy is that glazing may fracture but not cause hazards to personnel.” William Holley, chief engineer, Office of the Chief Architect, GSA, Washington, D.C., made the last presentation of the symposium, “GSA Protective Glazing.” He offered an overview of GSA’s capital construction program and building security policies and practices. “I’m getting heavy push from the Congress, the industry and the global warming environment for energy-efficient buildings,” he said. “Congress wants all buildings to be carbon neutral by 2015, and that’s around the corner. So, I’m looking for integrated glazing design that will address blast resistance, increased daylighting, minimized glare, reduced heat gain and hurricane resistance.” Henry Munford, vice president of development, SafeAmerica, Marietta, Ga., also spoke at the symposium on “The Purpose of SafeAmerica.” For more information, click here. —By Sahely Mukerji, Managing Editor, Glass Magazine, Auto Glass magazineShare this article:
