Project Name   
John Heinz Elevated Boardwalk and Observation Deck

Project Description
SJH provided 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 and the diverse wildlife, freshwater tidal marshes, open waters, mudflats, and woodlands that support hundreds of species. 
The project involved the installation of a boardwalk and platform helical piers meeting design load requirements, with special environmental concerns 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 were also inspected. Strict compliance with Army Corps of Engineers, Pennsylvania DEP, SHPO, EPA, and OSHA regulations were maintained.
Our construction manager reviewed and approved payments and schedules. Daily inspection logs were maintained, utilizing the Fish and Wildlife Service form, and included photographs documenting the site conditions and work progress reports. During construction of the elevated boardwalk, constant coordination was maintained with Refuge staff. Our staff was responsible for routing submittals, processing and responding to requests for information, and reviewing and recommending change requests to the contracting officer. SJH’s construction manager reviewed all close-out documents for completeness and assisted the agency in issuing a final certificate for payment.
