Features Casting the Vision: Keeping Your Workers Focused

Perhaps the most visibly distinctive trait of a construction field leader is the ability to keep the "troops" focused on their current and future work. Some practical techniques that you can incorporate immediately are: create a vision, cast the vision, and then recast the vision. Read more

Features The Pulitzer Foundation for the Arts

Emily and the late Joseph Pulitzer Jr. needed a home for their art collection. Introduced to the work of Tadao Ando—Japan's leading architect and a proponent of modernist architecture—they asked him to design the building. Initially they planned to rehabilitate an old building, but Emily Pulitzer later decided that a new building would be better. And she wanted a building as beautiful and perfect as the art it was to house. Read more

Features Race of Olympic Proportions: Utah I-15 Reconstruction

Despite 4 years of diverting rush-hour traffic and obstructing Salt Lake City's main freeway with orange barrels and construction equipment, Utah's Department of Transportation boasts a 75% public approval rating. This remarkable accomplishment is a testament to the largest highway design-build project ever awarded to a single contractor having been finished under budget and ahead of schedule. People with vision and dedication are always found behind such impressive results. This is true in the reconstruction of I-15, a massive rebuilding of a deteriorating urban interstate in preparation for the 2002 Winter Olympic Games. Read more

Features California Concrete Adventure

During the fall of 2000, radio, TV, and print ads announced the impending openings of Disney's California Adventure theme park, Downtown Disney (an adjacent pedestrian mall), and the adjoining Grand Californian Hotel. Excitement and curiosity were growing among the general public. The concrete contractors working on these projects, however, had markedly different feelings. Read more

Features Concrete Boxes

How do you build tunnels of interstate highway four lanes wide through poor soil beneath vital railroad tracks without shutting down the rail lines? This was the dilemma faced by the Slattery/ Interbeton/White/Perini Joint Venture, working on a portion of the Central Artery/Tunnel Project—often called the Big Dig—which will result in 7.5 miles (161 lane miles) of I-93 and I-90 buried under central Boston. The multibillion-dollar undertaking is reported to be the largest and most complex urban infrastructure project in American history. Tunneling under railroads usually involves relocating tracks—or taking all or a portion of the tracks out of service—and building staged cut-and-cover tunnels. This was not a viable option in Boston because of the many rail lines funneling more than 300 daily commuter and Amtrak trains into the city's South Station. These vital tracks bisect eastbound and westbound extensions of I-90 that are now being built and that will provide high-speed access to Logan Airport via the new Ted Williams Tunnel under Boston Harbor.

Concrete Basics Design of Concrete Beams

Most concrete design textbooks include a chapter on how concrete behaves in bending. Why talk about concrete bending when the all-too-common cracks in concrete show that it obviously doesn't bend? Although plain (unreinforced) concrete doesn't bend—at least not much—reinforced concrete does, and the design of concrete beams is based on how this bending takes place. Read more
