A typical job for the Bocell brothers starts with a phone call. “Nothing else had worked. Figured we’d give it a shot,” says Stanley Wondolowski, manager at a Corpus Christi, Texas, condominium association, recalling the day he dialed the Bocell’s number. “Every time it rained, it was a swimming pool down there.” CGI Texas, Dallas, knew how to handle the leaky concrete parking structure. “They drilled holes in the concrete, shot this gel into it, and the leaks stopped. It was very successful,” says Wondolowski. Photos courtesy of Marshall Bocell The CGI Injection Pistol requires only a single hole to

Heating, ventilating and air- conditioning systems are often invisible to the occupant. Hidden behind walls and snaking through ceilings, HVAC is noticed only when it breaks down.

At the site of a new $8.5-million, three-story dormitory at Southern Nazarene University in Bethany, Okla., the Versa-Floor HR floor system is getting its first real-world application. The prefabricated steel deck is joined and fitted with channels on the ground. Then, the 30 x 30-ft steel panels are lifted into place by a crane. Once connections are made to the structural columns, it’s almost ready for the concrete slab to be poured. “That’s the genius of the system,” says Aaron Ford, project manager on the dormitory project and associate principal with structural engineering firm L.A. Feuss Partners, Dallas. “We build

Getting energy-efficient design into school construction can be tough, but the Gen7 modular-classroom building from American Modular Systems, Manteca, Calif., fits many of the latest energy-efficiency advances into one package, bringing the cutting edge of green technologies to modular school construction. Photo: American Modular Systems Gen7 modular classrooms are showcases of sustainable technologies. Introduced at the Green California Schools Summit 2009 in Pasadena, Calif., in December, Gen7 is being touted as a “grid-neutral” modular-classroom solution for California school districts. “Gen7 is a loaded model, with every possible option,” says Tony Sarich, vice president of operations for AMS. “It’s not the

California Engineering Contractors, Pleasanton, Calif., was not happy with its high-speed Internet options. Even while paying thousands of dollars a month for bonded T1 lines or similar high-end connectivity at its main office, field offices at projects were often stuck with limited broadband. “In construction, sometimes you just don’t have the facilities for a T1,” deadpans Sam Hanna, CEC Internet technology director. Photo: Mushroom Networks The Truffle can bond up to six internet connections. But most of the company’s data traffic moves between project sites and the main office, and slow connections and digital bottlenecks can cost money. So CEC

Mapping existing broadband service is a requirement for states angling for a piece of the roughly $4.2 billion in matching American Recovery and Reinvestment Act funds for high-speed Internet expansion. But with a deadline approaching, states and municipalities have been scrambling to find the data. Photo: Connected Nation Michael Ramage (left) explains BroadbandStat at its debut at a Congressional policy exhibition in Washington, D.C., where it attracted interest from local officials seeking to expand broadband. Now, a new tool is available to help. In February, Connected Nation, a Washington, D.C.-based nonprofit dedicated to expanding high-speed Internet access, launched BroadbandStat, a

The perennial problem of workforce shortages and worries about bringing a new generation into the construction industry are nothing new for Bob Bailey.
