Construction


Carlstadt, NJ: Wetland Mitigation

wetlands-construction-carlstadt-nj

Geo-Solutions Inc. finished Phase 2 of the wetland mitigation bank construction in the New Jersey Meadowlands. Similar to Phase 1, Phase 2 was performed under a design\build contract with The Louis Berger Group. The 86-acre wetland mitigation bank was constructed at the Williams Gas Pipeline facility in Carlstadt, New Jersey. Construction started in November and has continued through the winter. Approximately 80,000 cubic yards of sediment and dredge spoil material was excavated and used to create new low and high marsh habitat. All excavated material was re-used, eliminating the need to import off site fill or dispose of the excavated material. The work was performed exclusively using mechanical excavation equipment. The site is situated on the Hackensack River and several different methods were used to eliminate normal tidal influences so construction could be performed "in the dry".

Over 3,000 linear feet of tidal channels were mechanically excavated to allow the new low and high marsh areas to experience tidal flushing and create open water areas. The material excavated from the channels was used to construct the upland island habitats. Three separate islands were created and the largest island required more than 50,000 cubic yards of material to construct. The work force is comprised of Geo-Solutions personnel and members of Operating Engineers Local 825. The Site Manager worked closely with the Louis Berger design team on a daily basis to adjust the project design and maintain the schedule.
