This scope of work outlines the requirements for pavement markings on highways and parking lots in Park City, Utah, ensuring compliance with the Manual on Uniform Traffic Control Devices (MUTCD) standards, as well as the Utah Department of Transportation (UDOT) specifications and local municipal requirements. Work includes surface preparation, layout, application, and quality control for pavement markings, considering Park City’s cold climate, high-altitude conditions, and seasonal snowfall impacts. 2.2 Requirements: A. Materials Pavement markings shall use thermoplastic, epoxy, waterborne paint, or preformed tape, as specified by PCMC and UDOT requirements. Materials must comply with MUTCD, UDOT, and ASTM standards for durability and retro reflectivity, especially for winter conditions. Reflective glass beads must meet ASTM D6359 to enhance visibility in low-light and snowy conditions. Cold-weather resistant materials shall be used to withstand temperature fluctuations and snowplow wear. B. Surface Preparation Ensure surfaces are clean, dry, and at appropriate temperature before applying markings. Remove existing markings via grinding, hydro blasting, or approved chemical methods to maintain surface integrity. Special attention is required for high-traffic areas and snowplow-prone roads to improve adhesion and longevity. Cold planer for inlay of thermoplastics. C. Layout & Alignment All striping must follow MUTCD Chapter 3 and UDOT pavement marking guidelines. Pre-mark all lines using chalk or lasers for precision, considering hilly terrain and curved roads in Park City. Verify correct lane widths and parking space dimensions per local zoning and ADA regulations. D. Application Methods Apply markings using airless sprayers, thermoplastic applicators, or manual preformed tape installation. Standard striping dimensions: Lane Lines (Solid/Broken): 4-6 inches wide Edge Lines: 4-6 inches wide Crosswalks & Stop Bars: 12-24 inches wide Parking Stalls: 4 inches wide Ensure proper drying/curing times, particularly in cold-weather conditions. E. Winter Considerations & Snow Removal Impact Use durable thermoplastic or epoxy paint in high-snow areas to resist wear from snowplows. Ensure retroreflective properties for enhanced nighttime visibility, especially during winter storms. Follow PCMC snow removal schedules to prevent fresh striping damage. F. Traffic Control & Safety Follow MUTCD Part 6 and UDOT work zone requirements for temporary traffic control during striping operations. Use flaggers, cones, and advance warning signs to manage pedestrian and vehicle traffic. Plan striping work to minimize lane closures and disruptions, especially during Park City’s peak tourist seasons. G. Quality Control & Inspection Visual & Reflectivity Inspection: Ensure proper color, thickness, and retro reflectivity compliance. Adhesion & Durability Testing: Conduct adhesion tests to withstand Park City’s climate. Striping Tolerances: Longitudinal lines: ±1 inch alignment Line width: ±0.25 inches H. Cleanup & Final Acceptance Remove debris and excess materials to keep roads and parking lots clean. Conduct final walkthroughs with PCMC inspectors to ensure compliance. Provide final inspection reports to PCMC Public Works or UDOT for project acceptance.
