Contractors bear all costs for construction sampling, testing by licensed Oklahoma laboratories, material procurement, equipment, temporary facilities, utility coordination (requiring 21 days advance notice for service interruptions), contaminated soil management, and project cleanup and restoration. Work is restricted to standard hours of 0700 to 1645 on weekdays. Contractors must obtain dig permits, burn permits, and portable sanitation units and implement Foreign Object Debris prevention measures. Certified testing laboratory reports must be submitted within 24 hours of test completion.
