Project Description

SJH is providing inspection services for the construction of elevated boardwalks and observation platforms at the National Wildlife Refuge in Philadelphia, PA. Established in 1972, the refuge aims to preserve, restore and develop the Tinicum Marsh. The refuge contains a diversity of wildlife, freshwater tidal marsh, open waters, mudflats, and woodlands that support hundreds of species. The project involves the installation of boardwalk and platform helical piers meeting design load requirements, with special environmental concern for the sensitive freshwater and tidal wetland areas. One observation platform is 16 feet by 24 feet, and the other is 16 feet by 16 feet. The installation of gravel trail, benches, framing, decking, railing, steps, and roof structures are also being inspected. Strict compliance with Army Corps of Engineers, Pennsylvania DEP, SHPO, EPA, and OSHA regulations are maintained.


Our construction manager is reviewing and approving payments and schedules. Daily inspection logs are maintained, utilizing the Fish and Wildlife Service form, and include photographs documenting the site conditions and work progress reports. During construction of the elevated boardwalk, constant coordination is being maintained with the Refuge staff. Our staff was responsible for routing of submittals, processing and responding to requests for information, and reviewing and recommending change requests to the contracting officer. The construction is estimated to be complete in 2015, and the construction manager will review all close-out documents for completeness and assist the agency in issuing a final certificate for payment.
