FLOAT-IN DAM CONSTRUCTION.
Glosten was brought on board to support the Olmsted Locks & Dam replacement project on the Ohio River in 2004. Construction was carried out using the method of building “in-the-wet” to minimize impacts to river traffic and the environment, which involved assembling shell segments of the dam on land, moving them to the water, and setting them in the river within a fraction of an inch tolerance. Glosten worked closely with Washington Group/Alberici (now AECOM) to design three highly specialized vessels to prepare the river bottom, transport, and precisely install the dam segments into location.
