Beginning the week of May 23, and over the next few weeks, approximately 250 steel panels for the third phase of the underground barrier wall will be delivered to Honeywell property just north of the I-690 bridge over the railroad tracks. The panels will be driven into the ground along the southwestern shoreline of Onondaga Lake to complete the 1.5-mile-long barrier wall, which is preventing contaminated groundwater from reaching the lake. Honeywell is scheduled to begin installing the interlocking steel panels this summer.
The steel panels are assembled and coated by JPW Structural Contracting, a local contracting firm based in Syracuse, N.Y. Each panel weighs up to 4.3 tons and ranges from 44 to 77 feet in length. Contractors will apply a waterproof sealant between each interlocking steel panel and connect them by sliding the interlocking joints together.
The interlocking steel panels will complete the third and final phase of the barrier wall, which is 4,700 feet long and runs from the East Flume to approximately 1,150 feet east of Harbor Brook parallel to the CSX tracks. There are 1,033 panels in the third phase of the barrier wall.
More than 100 additional steel panels will be delivered in July during construction of the barrier wall. The barrier wall will be completed by early 2012.
