LARGE PROJECT OF THE YEAR NOMINEE SR-12; ESCALANTE MAIN STREET TO MP 70 This nominated project placed approximately 8,245 tons of HMA 3/8 Inch material in the amount of $1,014,100.56 as a lane leveling course over the existing HMA. Once the lane level was placed a 1 ½ inch overlay with 16,810 tons of SMA ½ Inch was placed in the amount of $2,067,680.43. This project included a mill and fill of SMA on Main Street in Escalante from MP 58.86 to MP 59.85. From MP 59.85 to MP 70 an HMA lane level SMA overlay was placed. Due to the winding and narrow nature of SR-12, the Utah Highway Patrol limited the route to bring in a hot plant. It was required to bring in the hot plant from the west side of SR-12 and not over the Boulder Mountain. Once the hot plant was set up, it was located on the south side of the Escalante River. This caused potential problems and often made the road to and from the hot plant impassible due to flash flooding upstream of the project. It was critical that the project team worked with the county, school district, Escalante Town, to ensure that the construction of the grade of these areas was completed prior to the anticipated paving schedule. WW Clyde’s partnering efforts were truly exceptional as they exceeded the project expectations in paving and in the quality of their product. When it comes to project quality, the quality of the product and ride was remarkable. For the SMA, they were able to achieve $2.60 per ton as an incentive. For this roadway, the contractor was able to pave the project in a manner to achieve over 75% of the possible smoothness bonus. Typically, it is estimated that for budgeting purposes, the contractor could achieve 70% of the possible smoothness bonus. Add into this project sharp compounding curves, intersection tie-ins, trucking issues, it puts into perspective the top-quality job that was completed. One additional aspect that was mentioned earlier was the intersection tie-ins. This project included the construction of 35 pedestrian access ramps. As part of the construction of these ramps, paving in and out of them are critical to make sure ADA requirements are met for clear space and crosswalk running and transverse slopes. LARGE PROJECT OF THE YEAR NOMINEE TOOELE VALLEY AIRPORT REHABILITATION The Tooele Valley airport project consisted of 3D milling and paving of the taxiways and runway, the installation of new LED light fixtures, new striping, survey markers and grade work. The work was phased to allow for the runway to remain open as long as possible. A two-week closure was allowed for the 3D milling, paving, striping, electrical installation, etc. for all things related to the runway. What makes this project unique is that all the taxiways and runway were redone. This project was 3D milling and paving of the entire airport, save a staging area for planes. The 3D design of the project was such that Granite Construction, Inc.’s internal and external survey teams spent months redesigning the owner’s design due to constructability errors. The original design caused the 3D milling to remove all of the HMA in the runway in certain locations. This caused a chain reaction that increased the milling SY and resulted in a change order for lane leveling of the deficient areas. Jackson was responsive in removing and squaring up the deficient areas so they could be paved. Granite Construction, Inc. mobilized a paving crew specifically for the patchwork paving caused by the design. The survey crews on this project are what made it a success. Both internally and externally, an extensive amount of survey work was done pre-construction with the design, during construction with survey crews onsite with multiple total stations tracking mill depths and paving final elevations, joint layout etc. Workplace safety was especially critical during the runway phase with so many moving parts. Milling, Echelon paving with two shuttle buggies, over 25 trucks for both operations, crack sealing, surveyors and owner’s reps. The work was phased on the runway to create an environment for maximum production for each work type while maintaining the safest possible layout for each type of work. The project received an overall pay factor on the HMA of 1.06. The highest available factor from the FAA. Inspections and reports were done daily and submitted to the owner as part of the QA/QC Plan. The owner was highly involved with multiple onsite meetings with the design team, inspection team and other airport reps. 36
