Value: $ 730,000
Panther was awarded a contract to demolish two existing wooden boardwalks and to replace them with pre-cast concrete boardwalks at a wetland mitigation site located in Port Norris, New Jersey. The project is part of the clients Estuary Enhancement Program which was started to preserve and/or enhance more than 20,000 acres of Delaware Bay tidal wetlands and adjoining upland buffer areas that surround the Salem Generating Station. The purpose of the boardwalks is to make these sites more accessible and educational to the local population. The original wooden boardwalks were constructed in 1996 and were damaged in 2012 during the storm surge associated with Hurricane Sandy. The project involved the demolition of approximately 450 linear feet of wooden boardwalk, observation platforms and approximately 346 Helical Piers and replacing it with approximately 300 linear feet of precast concrete boardwalk, observation platforms, and 112 new Helical Piers that will be installed to 25 feet below grade with a minimum strength of 4,200 foot-pounds. The entire project was designed by the client and included the PermaTrak precast concrete system and supporting helical piers manufactured by AB Chance and is rated for wind loads of up to 120 MPH. The final system also includes up to 600 linear feet of galvanized hand railings that require assembly and field welding after the boardwalk has been constructed. The project will be installed in two phases, with the first phase having already been completed in 2017 and the second phase scheduled for construction in 2018. All work will be performed under tidal conditions working on floating plastic Durabase mats, with much of the construction being completed at heights exceeding 10 above the level of the marsh. Panther crews worked more than 1,000 man-hours to date without any safety incidents and completed the project on time and under budget. (701171014)
