PUBLIC CONVENIENCE AND SAFETY, BARRICADES, LIGHTS AND WARNING SIGNALS. Where the Work is carried on in or adjacent to any street, alley or public place, Contractor shall, at Contractor’s own cost and expense, furnish and erect such barricades, fences, lights and danger signals, and shall take such other precautionary measures for the protection of persons and property and of the Work as is necessary or required by the Contract Documents. Excavations in or adjacent to public streets or alley in which water stands more than one (1) foot deep or where banks of the excavation are subject to collapse or cave-in shall be securely barricaded with snow fence so as to prevent access by children and adults during the period when work is not being carried on at the site of excavation. Barricades shall be painted in a color and reflectorized in accordance with the provisions of the most current version of the Minnesota Manual of Uniform Traffic Control Devices (“MMUTCD”). From sunset to sunrise, Contractor shall furnish and maintain at least two (2) flashing lights at each barricade. A sufficient number of barricades shall be erected to keep vehicles from being driven on or into any of the Work and to warn pedestrians and children of the existence of the excavation at all open points. When a detour is necessary because a street is blocked by the Work, the Engineer shall designate its route and Contractor shall furnish and post detour signs at places designated approved by the Engineer. All signs shall be in accordance with the most current version of the MMUTCD and appendices. Contractor shall be responsible for all damage to the Work due to failure of barricades, signs, and lights to protect it, and whenever evidence of such damage is found, the Engineer may order the damaged portion immediately removed and replaced by Contractor at Contractor’s expense. Contractor's responsibility for the maintenance of barricades, signs and lights, and for providing the watchmen, shall not cease until the project has been accepted by the City.
