I’m not going to talk about trenches in this article, even though they are still necessary ways for improving some projects. There are projects that do involve some digging (how else would you get underground?) but t...... continue reading

Written by Jeff Winke When the February 22, 2011, Christchurch City earthquake erupted, this powerful natural event severely damaged New Zealand’s second-largest city and has been described as one of the nation’s worst peacetime disasters. To add context, the Canterbury region had been experiencing earthquakes since the September 2010 Darfield event, with over 10,000 recordable earthquakes to date. One significant road damaged in the quake required the Christchurch City Council’s (CCC’s) immediate ...... continue reading

Written by Carol Brzozowski Hydro- and vacuum excavating systems are becoming so much an increasing part of the construction site landscape these days that one manufacturer states it’s been the busiest year for his company to date, with the demand in some cases exceeding supply.

Written by James McRay If the saying goes, “The whole is more than the sum of its parts,” then all those parts must absolutely be important in creating a dynamic final product. This adage is especially true at Chicago’s O’Hare International Airport, one of the world’s busiest, which is in the midst of one of the country’s largest construction projects. The O’Hare Modernization Program (OMP) is transforming O’Hare International Airport’s airfield from an outdated system of intersecting runways into ...... continue reading

As the old adage goes, “One good idea begets another,” an apropos slogan for Bacco Construction Co., based in Iron Mountain, MI, which has recently undertaken two very important excavation projects in Sault Ste. Marie, MI. The first project was a $9,500,000 storm-sewer separation upgrade in downtown Sault Ste. Marie, just east of the town’s historic Soo Locks. Excavation challenges abounded on the project, not the least of which was that of finding an appropriate and cost-effective shoring system. Bacco...... continue reading
