The contractor should take caution at the five (5) foot mark on any side of a utility pre-identified to the contractor. Mechanical digging shall not commence, within 5 ft of buried utility lines, until locations of those lines have been established and properly verified by hand digging. If the contractor damages the marked utility within this area, he/she is responsible for replacing the utility back to its original working condition. Work to repair the damaged utility will commence immediately and will continue uninterrupted until the utility is restored. If the contractor damages a utility that was not identified or is outside 5 feet either side of the utility marking, the contractor shall notify the CO and the Construction Inspector to determine the method of repair (i.e., in-house or by contract). If the damaged utility requires an outside source (e.g., someone to repair fiber optic lines) to accomplish the repairs, and the contractor is responsible for the damage, and the contractor shall be liable to pay for such repairs.

5. POWER OUTAGES: Work shall be planned so that power outages will interfere as little as possible with base operations. Wherever possible, portions of the work that can be accomplished without a power outage will be done prior to outages. All materials, equipment, and labor required during a
