From the outset and throughout the project, weekly meetings were held with DIA Management, DIA Operations, and FAA representatives through the project duration. All potential conflicts were addressed and resolved.

Closed on August 25, the runway was re-opened on time by October 12, thanks to the hard work, ingenuity, and tenacity of the dedicated team.

Concrete Pavement Restoration (CPR) — Silver

Project:               Interstate-15 (from Interstate-84 to 10th North, and 10th North to SR-30), Box

Elder County, Utah

Contractor:            Multiple Concrete Enterprises, Inc.
Owner/Engineer:      Utah Department of Transportation

This two-phase Concrete Pavement Restoration (CPR) project was particularly challenging because of the project scope, heavy traffic in the area, and because of restrictions on how work on the second phase was to proceed.

Interstate-15, from the Interstate-84 Interchange to SR-30 in Utah, was paved in 1988 with 10 in. concrete over lean base. After more than two decades of service, a pavement preservation contract was let in the spring of 2011 for full-depth panel replacements; spall repairs; dowel bar retrofit; profile grinding; joint sealing; slab jacking; signs; electrical; fencing; and miscellaneous repairs within the right of way.

The total engineer’s estimate of the project was more than $7.7 million, but the low bid came in at $6.2 million, about 80 percent of the original. The main items of concrete rehabilitation included 2,870 SY of panels; 186 SY of partial-depth spall repair; 314 CY of slab jacking; 83,643 dowel bar retrofits; and 308,150 SY of grinding.

Minimizing inconvenience and ramp closures was important, as was keeping workers and the traveling public safe. The effort required exceptional partnering between Multiple Concrete Enterprises, Inc. and Utah DOT personnel.
