Object Blocking Giant Tunnel Borer Was an 8" Diameter Pipe

An anonymous reader writes "A few weeks ago we discussed news that a tunnel boring machine measuring 57.5 feet in diameter was halted underneath Seattle after running into a mysterious object. Project engineers have now figured out what the object is: an 8-inch-diameter pipe. In 2002, researchers for another project — the replacement of the Alaskan Way viaduct — drilled down into the ground to take water samples. They used the 115-ft-long pipe as a well casing. As it turns out, this well site was listed in the contract specifications given to all bidders for the tunnel's construction. In addition, the crew manning the machine noticed that it was chewing up pieces of metal, and they removed part of the pipe and kept going. Only later did they realize that significant damage had been done to the machine's cutting face. Officials aren't sure how long repairs will take, or how much they will cost."

  1. They must have hired IT Managers to plan this job by marcgvky · · Score: -1, Offtopic

    You see, IT Managers don't plan anything and, when cautioned by the Project Manager to spend additional funds to plan the path and remove obstacles BEFORE starting work, they always opt to not spend that money; let's just start the work. Resulting in lost productivity, low morale, and cost-doubling rework. LOL Good job construction morons, welcome to the world of elite IT Management theory.
