Washington Patriot Construction faced the challenge of installing a vehicle barrier system at locations that were nothing like the testing locations.
The company developed a technique that allowed the barrier to follow the terrain. The system needed to bend around duct banks in order for intermediate posts to be installed.
Project sequencing consisted of installing 2 miles of various barrier types and their foundations around undocumented underground utilities. The company chose to install intermediate posts that support the barrier system after the termination-post locations were set, enabling them to move the system between the termination posts in and out along the changing topography and avoiding underground utility locations.
Washington Patriot effectively scheduled their workforce and mitigated material-delivery issues to finish ahead of schedule. Their team worked a total of 19,429 hours with no incidents or accidents, and received an interim performance evaluation from Naval Facilities Engineering Command Northwest that rated them above average.
