Cutting a big job down to size

摘要

Texas State Highway 183 from Euless to Dallas/Fort Worth underwent a $1.6 billion major reconstruction in 2014. On projects of this size, even small changes can lead to a great deal of extra work. Such was the case when an unexpected grade change was required to correct drainage issues. "It was a surprise; the road was raised up to 4 inches after utility manholes had been installed," says Jonathan White, operations manager at Cheyenne Construction Co. of Mansfield, Texas, a concrete subcontractor for the project. "That meant that 300 to 400 manholes needed to be uncovered and raised to grade."
