R.L. McCoy, Inc., a highway and bridge construction company based in the Fort Wayne, Indiana area, was contracted to build a 330' long access tunnel with 18" thick walls and an 18" slab overhead. Because the 14' high and 16' wide inside dimensions were larger than conventional box culverts, Mark McCoy was concerned with properly supporting the center of the overhead forms during construction.
Finally, a plan to use the Box Culvert Traveler components with the Versiform® panels that the contractor already owned for the interior, Max-A-Form panels on the exterior and Steel-Ply® panels as headers supported by a center Post Shore was approved.
John Christiansen arrived on the job site to
provide the R.L. McCoy crew with instructions
on assembling the 42' traveling sections. Once
the system was put together, the forms were
cycled every 4 days and the job was successfully
completed in five weeks.
