该团队的任务是完全修复8500英尺，150英尺宽的跑道在萨克拉曼多国际机场，不仅是按计划进行的，而且还达到了人行道平稳性的创纪录行业标准。
The project entailed demolition and reconstruction of the existing runway and construction of a subsurface drainage system. The runway, just one of two, has an instrument landing system that allows pilots to land in foggy conditions. Crews worked up to seven 12-hour days a week and achieved 105,400 worker hours with zero injuries.
意外的现场条件包括包括石棉水泥的现有电气管，不合适的子级区域以及需要充分重建而不是重新设计现有的爆炸垫。该团队致力于迅速解决400万美元的范围变更，并按计划保持工作。
花岗岩建筑使用3 d为控制公关oduce an industry gold standard in smoothness. “This was the first time Granite Construction has utilized 3D stringless concrete paving technology,” says Steve Lynch, regional project manager with Granite. “We have utilized robotic total stations for 3D grade controls on our grading and asphalt paving equipment on multiple prior projects.”
The tools helped to produce finish grades with a maximum deviation of 0.02 ft from design grades and an average smoothness profile index rating of 1.7 in./mile, compared to the allowable 7 in./mile.
切开的槽操作产生了750,000加仑的混凝土浆液，需要适当的处置。该项目团队使用工业泥浆新闻开发并实施了解决方案，该新闻允许通过按下固体来持续重复使用水。然后将所有固体回收为骨料碱，没有排出浆液。项目团队还重复了115,000立方英尺的拆除和挖掘材料中的100％。
