摘要

How do you deliver 78,298 cu yd of ready mix concrete, 270,000 cu yd of paving concrete, move 1.2 million cu yd of dirt, rehabilitate 30,000 linear ft of sewer line, recycle 700,000 sq yd of concrete pavement, place 850,000 tons of aggregate base and 85,000 linear ft of concrete barrier wall all in less than six months? Cordoning off an entire freeway is not something entered into lightly. Yet, success on previous roads projects demonstrated to the citizens of Michigan that a full closure of I-96 between I-275 and M-39 would minimize the impact of a reconstruction megaproject aimed at breathing new life into the state's freeway system. Thus, under full closure, 7 miles of urban freeway including 56 lane-miles of concrete pavement, 22 ramps, 37 bridges, 74 approaches and 10 retaining walls were reconstructed in 167 days. The freeway closure started on April 5, 2014, and it was reopened to traffic in mid-September. Dan's Excavating, CA Hull and Ajax Paving Industries along with numerous subcontractors and suppliers completed this project encompassing more than 600,000 man-hours with but a single lost-time injury. And aside from plain old hard work, there were several innovations implemented that led to the success of this project, among which electronic contracting, 3-D project control and well-graded concrete mixes stand out.
