24 QUALITY IN CONSTRUCTION SUNROC — CEDAR CITY AIRPORT WINNER Name of project: Cedar City Airport Project location: 2560 Aviation Way St, Cedar City, UT 84721 Project start: March 16, 2020 Project completion: Sept. 9, 2020 Key project team members: • Kelly Cox, Project Manager • Tyler Cornelius, Project Superintendent • Larry Cox, Asphalt Superintendent • Cameron Carling, Project Engineer Key subcontractors: • Mesquite Electric • Construction Materials Recycling • Cardinal Grooving • KW Concrete • Straight Stripe Painting Project overview: This project consisted of a Full Runway 2-20, Runway 8-26 Reconstruction and RSA Safety Grading, com- pleted in phases to accommodate the local SUU avia- tion school and local FedEx deliveries. What makes the project unique? Sunroc maintained extremely tight survey control with veri- fied control points approximately every 1,000 feet. A combina- tion of 3D GPS control and Total Station control was used to fine- tune the finish grade elevation of the subbase and base. A robotic paint machine was utilized to mark edges of all pavements and paving lanes, maintaining straight joints and pavement edges. The entire site was constructed solely with 3D machine-controlled equipment. The GPS system set up on-site was used by both the con- tractor and the surveyor to max- imize efficiency in results for the tight grade tolerances achieved. Echelon Paving was used to reduce longitudinal cold joints in the runway surface, improving consis- tency in asphalt compaction and extending the life of the runway. Overburden from an old iron mine was sourced for P-209 base under asphalt, reducing the number of resources required from local commercial pits. A close mate- rial source was also found and met specifications for P-152 borrow. This reduced the amount of truck traffic to the public as well as the environmental impact. Our team demonstrated a high level of teamwork and collab- oration to solve a variety of unique challenges. The project’s extremely tight schedule required Sunroc to efficiently manage labor forces, equipment, and mate- rial resources to meet project deadlines. Our team successfully planned and prepared to secure the appropriate resources to com- plete all deadlines. In addition, our team put in incredible effort, typically working 11-hour days and six days per week. Overall, the project was completed 30 days ahead of schedule. 3
