Old Mountain was engaged to triple the capacity of the on-campus stadium at the new Marietta High School.  The old capacity of the stadium was making it difficult for family and friends of student-athletes to attend many events.  Old Mountain cleared the wings next to the stadium, re-graded, laid in concrete foundations and worked with the stadium seating contractor to place the new seating, placed retaining walls, directed concrete encapsulation, and built two new pavilions above the stadium to allow crowd movement and support activities related to athletic events a place to occur.
