This is true, but how much time did it take to complete the job?? It seems that with todays expertise, it should take much less time than its taking. That was my point.My basic geology class at St Helena's taught us that Long Island is an "outwash plain" aka residue left over from a giant retreating glacier (huge sandbar in other words). Manhattan was solid rock, much different, geologically speaking than Long Island. That explains the relative ease of building the Independent subway along Queens Blvd. Cut & cover thru sandstone. A "snap" in terms of subway tunneling. Bottom line,in LIC, the engineers should have known what they were digging thru & not seemed so suprised at what they found to justify delays which translates into cost overruns. Someones feet should be held to the fire. |
