National Park Service Brooks Camp Floating Bridge Replacement

RSA had been working with the NPS since 2013 on this Brooks Camp bridge project, which was completed and opened to the public in the summer of 2019. RSA provided mechanical and electrical engineering services for this project, which resulted with an elevated bridge and boardwalk across the Brooks River. The project goal was to replace the existing river-level bridge to minimize the possibility of bear/human interaction as well as improve operational efficiency, provide more appropriate viewing options, and minimize visual impacts. RSA’s mechanical design included a sewer pump out skid, sewer force main pipeline and valving, camlok fittings for attachment of suction hose, and pump controls that utilize a variable frequency drive. Other mechanical design features included a pig valve, air compressor, and air hose connection to allow pigging of the forced main piping after sewage pumping activities. RSA’s electrical design included a medium voltage line extension to connect the existing Brooks Camp distribution system to the existing Maintenance and Housing Loop distribution system. This 4160V, 3-phase line extension allows the NPS to power their main facilities from a single generating location, thus reducing park maintenance, operation, and fuel costs. The electrical design also included the necessary power distribution upgrades to accommodate the new sewage pumping system, as well as under bridge raceway to accommodate future cameras.
