The project included the installation of 2,675 linear feet of elevated boardwalk, 650 helical piles, and the seamless installation of a 50’ x 6’ Bedford ReadySpan™ pedestrian bridge, connecting key pathways in the Preserve offering visitors an enhanced perspective of the Preserve’s diverse natural features. To protect the Preserve’s sensitive environment, RENOVA , implemented comprehensive environmental protection measures, including erosion and sediment controls, high-visibility fencing, and ground protection matting to minimize construction impacts when wetlands intrusion was allowable.
Project Summary:
- Helical Pile Type: 3.5″ Pipe Piles .300 Wall 12″ 14″ Lead
- # of Helical Piles: 650
- Location: Cape May, NJ
- Installation Depth: 14′
- Helix Plates/Ultimate Pile Capacity:17,000Ft. Lbs Torque
- Equipment Used: Kuboto U35 7K &5K Ft. Lb. Drive Heads
- Challenge/Unique Aspect: The installation was incredibly challenging as the entire walkway had to be installed “build as you go” with no intrusion into the wetland permitted. This included the pre-fabricated bridge that spanned over a body of water and was in a remote area of the preserve. Boardwalk Sections had to be pre-fabricated and along with leads and extensions, transported by a dolly on the previously constructed sections. Amazingly, the project was delivered on budget, on time while seamlessly integrating the new bridge and boardwalk system into an existing trail system.
