4 • Utilities in poor condition that need replacement or repair • Utility One-Call marks not matching up with construction plan depictions. Initial project costs higher resulting from: • Contractors pricing utility risk contingencies • Investigation and processing of incomplete and inaccurate utility information Safety risks resulting from: • Damaged utilities affecting safe vehicle operation controls, such as traffic signalization • Traveler inconvenience resulting from closure of surrounding highways.
