PROJECT SUMMARY
Name of Project: Katmai Elevated Bridge and Walkway
Location of Project: Katmai National Park
Client: National Park Service
Situation
STG was awarded the Katmai National Park – Replace Floating Bridge and Access Trail with Elevated Bridge and Walkway project in 2016. The project would replace an old floating bridge on the Brooks River that frequently caused delays due to bear-activity on the easily accessed bridge. The new bridge would include approximately 1,150 linear feet of Elevated Boardwalk including Viewing Platforms and Ramps which would enhance visitor experiences from an elevated vantage point and eliminate bear traffic delays. Work was conducted during the 2018/2019 construction season.
Challenge
Being that this is a high-profile project due to the location set in a National Park, STG had to take extra care in preserving the natural environment. We had to take a “leave no trace” approach to construction by careful planning of equipment routes, minimized clearing and grubbing, designated construction areas.
Solution
STG field crews continually went above and beyond expectations on the project. The daily tasks required for this project were very detailed and required precise measurements and calculations. The STG project management team, procurement department and field crews ensured the success of this project through a strong team approach and close collaboration.
Construction consisted of driving piles both along the designated boardwalk and within the Brooks River, as well as existing/demo boardwalk, septic pump out system, housing loop utility improvements and power distribution. STG erected an 80’x40’ tent where all cutting and pre-fab work is performed to protect the environment from sawdust, debris and cuttings. Cuttings are stored in Supersack/containers for transport at demob.
Once materials were barged in and the tent fully erected, the project kicked off with pile driving efforts. Construction started at the north side of the Boardwalk and worked down toward the south end. The project consisted of prefab all glulam beams and joists, viewing platform glulam and joists, lay decking section by section working south, installing electrical and mechanical work septic pump out, installing handrails, bear gates and bear doors, septic conduit run and installing camera mounts. STG installed the 6 camera piles for webcams which were strategically located along the boardwalk so people all over the world can view livestreaming of bear activity. Our team assisted with design engineering for the steel support beam for the cable railing to make the handicap viewing more enjoyable.
Visiting Katmai National Park is on many bucket lists and STG was privileged to have been selected to work in such a beautiful surrounding. Crews encountered many wildlife while working on this project from bears to wolves. We are proud to have played a role in constructing a bridge that all can enjoy for years to come. We constructed the bridge with minimal impact to the natural surroundings. Care was taken each and every day to ensure we left the site just the way we found it or in better condition. We would like to thank the National Park and all National Park representatives in building a lasting partnership.
