While bankrupt General Motors is discontinuing its line of medium-duty trucks, the clock is ticking for others to clean up tailpipes in January. The clean-air regulation has Warrenville, Ill.-based Navistar International Corp. asking a U.S. appeals court in Washington, D.C., to review a February ruling by the U.S. Environmental Protection Agency. The EPA action provided guidance to diesel-truck makers on how to certify engines using selective-catalytic reduction. Navistar alleges EPA in 2001 did not deem SCR permissible due to the use of liquid urea, of which distribution and handling was questionable. Other producers argue urea is proven. Navistar is the
Aviad Shapira, civil engineering professor, textbook author and former project engineer for his family’s concrete construction business, is not afraid to climb hundreds of feet up a rickety ladder to get a bird’s-eye view of the world. “I climb tower cranes whenever I get the chance,” he says. “Too many of us researchers are detached from the subject.” Photo: Aviad Shapira Shapira is helping builders plan for tower-crane risks. The high-level view has afforded Shapira a unique perspective. The teacher at The Technion-Israel Institute of Tech- nology, Haifa, says many crane accidents can be attributed to what he calls a
A vehicle invasion is coming from Turkey that may take the U.S. business community by storm. Starting next month, Ford Motor Co. will be importing and selling its Transit Connect small van in the U.S. and Canada. The Turkish van’s flexible design allows it to be configured for a variety of businesses, and it is aimed at those in urban areas that need maneuverability in tight spaces. On May 28, ENR took one for a test drive in New York City and found that it does deliver the goods promised. Slide Show Photo: William G. Krizan / ENR Small van
It looks like some exotic piece of machinery for exo-planetary exploration, but in reality it is a futuristic concept cooked up by Volvo Construction Equipment of what an automated road paver in the third decade of this century might look like.

Construction pros are no strangers to heavy equipment, but two new machines working on the eastern span of the $5.5-billion San Francisco-Oakland Bay Bridge make most ordinary tools look like children’s toys.

Inside a darkened classroom in Mokena, Ill., a student lowers a face shield and braces a MIG torch above a small podium. The class hears the sounds of electric arcs hissing, while they size up the incoming weld as part of a contest to see who has the best “golden arm.” Photo: Tudor Van Hampton / ENR A pipefitter apprentice at Local 597 performs MIG welding in the virtual world. In a few seconds, the exercise is over, yet no sparks, heat or fumes—no real welding—actually happened here. It was all performed in a simulated world, a Guitar Hero for
More than 2,000 craft workers are buzzing like bees inside a new 1,600-MW powerplant under construction near Franklin, Texas. Supplying the trades with forklifts, grinders, welding machines, safety glasses—even ice for water coolers—normally would be a logistical nightmare for all the contractors involved in the $2-billion project. But AMECO, the chief supplier on the job, has been handling these services for over 60 years. At Luminant’s Oak Grove Steam Electric Station, due to supply power to about one million homes by mid-2010, AMECO is supplying $1.4 million in small tools along with more than 580 other larger items, like pickup
On Nov. 12, 2008, a new auction occurred. Cold, wet and windy, the day was not helped by the fall financial meltdown or the dreary mood at the site of the lead consignor: Midwest contractor McAninch Corp.’s maintenance yard in Des Moines. Prices matched the mood and were down by double digits compared to prior months. Photo: CAT Auction Services Cat’s first auction’s timing was bad, but firm says it was successful.

From the vantage point of a helicopter hovering 1,000 ft above an ocean of heavy equipment, the Ritchie Bros. yard in Davenport, Fla., looks like a giant sandbox flooded with construction toys. In between the neatly arranged rows of excavators, loaders, dump trucks and cranes are colorful dots—men, women and children—weaving in and out of aisles in search of a bargain. In the center of the action is a white building where buyers are sitting comfortably in jeans Slide Show Photo: Tudor Van Hampton / ENR Auction in Orlando was stuffed with thousands of pieces of yellow iron.
