Gregory Hauser laughs when he tries to recollect all the tunneling jobs in his 40-plus-year career. However, nothing compares to job No. 27, he says. Working on the $1.8-billion Brightwater wastewater treatment plant project—which included 13 miles of deep-bore tunneling—Hauser, 64, project manager for Livonia, Mich.-based Jay Dee Construction, helped to turn a bungled mess of stuck tunnel-boring machines into a hassle-free job.

他说，这项挑战使豪瑟（Hauser）早上起床，但这也使他在晚上起床。在布莱特沃特（Brightwater），他首先完成了四英里的隧道，然后重新配置了TBM“伊丽莎白”（Elizabeth），完成了1.9英里的延伸，另一家公司破坏了两个TBM。豪瑟（Hauser）与现为卡特彼勒（Caterpillar）的部门的洛瓦特（Lovat）合作，以修改伊丽莎白（Elizabeth）的地面压力完全不同，但钥匙是备份。豪瑟说：“一项好工作的秘诀是为所有假设计划。”

Planning and a good team, that is. "We had the cooperation of the consulting engineers and the owner," Hauser says. "It is critical, because those two entities get in the way of a successful job. The engineer was the engineer, the owner [was] the owner, and they let us be the contractor."

随着隧道的替代方式，成为承包商就足够了。但这就是他所知道的。豪瑟说：“当有最后期限和紧缩时，它变得有趣并保持果汁流动。”

King County, Wash., the owner, loved Hauser's determination. "In the tunneling business, Greg is a perfect person," says King County's project manager, Gunars Sreibers. "He steps back from a job and looks at what needs to be done and plans out intricate details of who should do what. He puts that detail into motion. It's just the nature of the guy."
