| 摘要： | Crews have completed the cofferdam at the Kentucky Lock Addition Project, a milestone in preparing for downstream excavation work that will include construction of the remaining portion of the new lock chamber. Johnson Brothers Construction, the contractor on the $68 million downstream cofferdam, is working on punch-list items now but has already turned over the completed cofferdam, said Jeremiah Manning, resident engineer with the Nashville Engineer District. "We had a great big challenging project," Manning said, referring to difficult river conditions in 2018 and 2019 that resulted in delays to construction progress and about one year of schedule growth. "Hopefully the tide is turning on this project, and we're isolating ourselves from our biggest risk factor, which is the tailwater at Kentucky Dam." Jody Robinson, contract administration team lead at the Western Kentucky Area Office, said the cofferdam is the most important spot on the job site because its specific purpose is to hold back the tailwater from construction activities. "This cofferdam is critical to the entire rest of the project," Robinson said. At one point during the height of the construction and installation of the concrete shells, Johnson Brothers had about 150 people on the job site, including subcontractors, which made for a very busy construction zone. |
