By Steve Goldberg When the Tennessee Department of Transportation decided to improve a 4-mile stretch of Interstate 65, project manager Todd Cheek of Mid-TN Erosion was called in to assist with sediment control issues. As he describes the project, “It is the grading, drainage, and construction of a concrete I-beam bridge, a concrete box bridge, and concrete paving, incorporating 14 noise walls and 11 retaining walls. Basically, it is taking three lanes of concrete paving out to five lanes, both north- a...... continue reading

Written by Margaret Buranen A study done by the Washington State Department of Ecology in 1992 found an average dust emission rate of 1.2 tons per acre per month for active construction sites. Another study by the same agency listed earthmoving, traffic, and general disturbance as the major dust-generating factors in construction work. Dust-generating work has to be done, of course. But for the public good, the dust and particulates so generated has to be minimized and controlled. Controlling...... continue reading

Written by Janet Aird “The use of permeable pavers has gone rampant,” says David Hein, an engineer with Applied Research Associates in Toronto. “It’s driven by the stormwater people. There’s been a major effort to deal with stormwater at the source.” While the goal of poured concrete and asphalt is to guide water away from their surfaces, the goal of the permeable paver system is to allow it to infiltrate into the ground below. And although they’re used most frequently for parking lots and driveway...... continue reading

Written by Larry Trojak As the benefits of a comprehensive GIS effort have become more and more apparent, larger cities and municipal utilities have been steadily getting on board with the technology, citing it as something of a no-brainer in terms of better asset availability, increased accuracy, ease of access to information, and so on. Smaller towns and cities, however, have been reluctant to make the same move, often citing it as both too daunting and far too cost-prohibitive. The City of Trout...... continue reading

Written by Steve Goldberg Above Fountain Creek, on the Fort Carson military base in Colorado, sits a railroad bridge spur. Luke Tourville of Gracon Corp. was asked to come in and perform some analysis for protection of the bridge piers. “The bridge is 275 feet long, from abutment to abutment,” he explains. “There are four main piers that are within the creek during heavy flows, and two main piers that are in the creek pretty much 100% of the time. “Our contract was to do the HEC-RAS modeling ...... continue reading

Washington, DC - (June 13, 2012) - The U.S. Green Building Council (USGBC) today announced that more than 20,000 homes across the U.S. have earned certification through the LEED for Homes program. LEED for Homes is a national voluntary certification system that provides guidance and verification that homes are designed and built to be energy- and resource-efficient and healthy for occupants. "There are green homes, and then there are LEED homes. This milestone is evidence that the residential market is ...... continue reading

Regionalization. It has been a while since this topic—and process—has been discussed in this column (as far back as the September/October 2010 issue), and many of you—especially new IECA members—may not even be aware of the most significant restructuring of the organization since it was founded more than 40 years ago. Almost 10 years after Australians Rick Morse and Doug Wimble initially proposed a major structural change, we finally are becoming truly international. And after a membership survey and su...... continue reading

By Janice Kaspersen Although it’s common, even fashionable, to use the word green to apply to almost anything that’s good for—or that isn’t actively harmful to—the environment, the term often has a more specific meaning. Green infrastructure is an approach to managing stormwater that relies on natural processes rather than engineered systems. It’s becoming more widely used in many cities, and, a new report claims, if used in the right way it can save lots of money as well. We see green infrastructu...... continue reading

W. CONSHOHOCKEN, Pa., March 28, 2012 -Forty-six ASTM International standards covering various aspects of building construction are cited in the 2012 International Green Construction Code (IgCC). Published today by the International Code Council (ICC), the new model code addresses the construction and remodeling of residential as well as commercial structures. The IgCC is expected to increase cost savings and job growth while enabling safe and sustainable building design and construction. ASTM Inte...... continue reading

On March 14, EPA posted to its website a new "template" for construction operators to use in developing stormwater pollution prevention plans (SWPPPs). SWPPPs are site-specific documents that are required as part of EPA's new 2012 Construction General Permit (CGP). The SWPPP template is designed to help construction operators develop a SWPPP that is compliant with the minimum requirements the new CGP. The SWPPP template allows operators to customize the document to the needs of the site, and includes ta...... continue reading
