(a) Repair Broken Lines. The contractor shall take immediate steps to repair any broken water and sewer lines and shall immediately notify the City of any damage.

(b) Project Coordination. The contractor shall coordinate his work schedule with the City to insure that adequate and timely notice is given to the fire, police, and utility departments, and to insure that scheduling with other construction work is closely coordinated. It shall further be the responsibility of the contractor to see that proper traffic signs, detours, and safeguards are provided, and that the property owners affected are notified and provided with interim utility service as required.

(c) Manner of Excavating. The contractor shall allow no excavation or tunnel to be made in any way contrary to or at variance with the terms of the permit therefor. Proper bracing shall be maintained to prevent the collapse of adjoining ground; and in excavations the excavation shall not have anywhere below the surface any portion which extends beyond the opening at the surface. No injury shall be done to any pipes, cables, or conduits in the making of such excavations or tunnels; and notice shall be given to the persons maintaining any such pipes, cables, or conduits or to the city department or officer charged with the care thereof, which are or may be endangered or affected by the making of any such excavation or tunnel before such pipes, cables, or conduits shall be disturbed.

(d) Sidewalks. If any sidewalk is blocked by any such work, a temporary sidewalk shall be constructed or provided which shall be safe for travel and convenient for users.

(e) Traffic Routing. Where traffic is affected, the contractor shall provide that proper signing and safeguards be in accordance with the Alaska Traffic Manual and shall notify the Police, Fire, and Public Works Departments to obtain clearance for the type of detour, time, and other limitations imposed. Flashing lights on barricades will be required during hours of darkness. The contractor shall take appropriate measures to assure that during the performance of the excavation work, traffic conditions as near normal as possible shall be maintained at all times so as to minimize inconvenience to the occupants of the adjoining property and to the general public. Warning signs shall be placed far enough in advance of the construction operation to alert traffic within a public street and cones or other approved devices shall be placed to channel traffic, in accordance with the instructions of the Director of Public Works. The contractor shall maintain safe crossings for two lanes of vehicle traffic at all street intersections where possible and safe crossings for pedestrians at intervals of not more than 300 feet. If any excavation is made across any public street, alley, or sidewalk, adequate crossings shall be maintained for vehicles and for pedestrians.

(f) Closing Streets. When traffic conditions permit, the Director of Public Works may, by written approval, permit the closing of streets and alleys to all traffic for a period of time prescribed by him, if in his opinion it is necessary. Such written approval may require that the contractor give notification to various public agencies and to the general public.

(g) Clearance for Vital Structures. The excavation work shall be performed and conducted so as not to interfere with access to fire hydrants, fire stations, fire escapes, water gates, underground vaults, valve housing structures, and all other vital equipment unless approved on the permit by the Director of Public Works.

(h) Restoration of Right-of-Way. Contractors will be required to restore the public right-of-way to the grade and condition originally found, to replace gravel, paving or sealcoating, ditches, culverts, fences, signs, or other improvements, unless specific authorization to the contrary is authorized in writing by the City. Failure to do so will be cause for the City to accomplish the required work, and to collect damages therefor from the contractor or his surety.

(i) Clean Up. As the excavation work progresses, all streets shall be thoroughly cleaned of all rubbish, excess earth, rock, and other debris resulting from such work. All clean up operations at the location of such excavation shall be accomplished at the expense of the contractor and shall be completed to the satisfaction of the Director of Public Works. Immediately after completion of said work, the contractor shall, at his or its own expense, clean up and remove all refuse and unused materials of any kind resulting from said work, and upon failure to do so within 24 hours after having been notified to do so by the Director of Public Works, said work may be done by the Director Public Works, and the cost thereof charged to the contractor, and the contractor shall also be liable for the cost thereof under the surety bond provided hereunder. The contractor shall maintain all gutters free and unobstructed for the full depth of the adjacent curb and for at least one foot in width from the face of such curb at the gutter line. Whenever a gutter crosses an intersecting street, an adequate waterway shall be provided and at all times maintained. The contractor shall make provisions to take care of all surplus water, muck, silt, slickings, or other run-off pumped from excavations or resulting from sluicing or other operations and shall be responsible for any damage resulting from its failure to so provide.

(j) Prompt Completion of Work. After an excavation is commenced, the contractor shall prosecute with diligence and expedition all excavation work covered by the excavation permit and shall promptly complete such work and restore the street to its original condition, or as near as may be, so as not to obstruct the public place or travel thereon more than is reasonably necessary.

(k) Urgent Work. When traffic conditions, the safety, or convenience of the traveling public, or the public interest require that the excavation work be performed as emergency work, the Public Works Director shall have full power to order, at the time the permit is granted, that a crew of men and adequate facilities be employed by the contractor twenty-four hours a day to the end that such excavation work may be completed as soon as possible.

(l) Emergency Action. Nothing in this ordinance shall be construed to prevent the making of such excavations as may be necessary for the preservation of life or property or for the location of trouble in conduit or pipe, or for making repairs, provided that the person making such excavation make a reasonable effort to notify police dispatch of the location of the emergency excavation. Such person excavating on an emergency basis shall apply for such a permit on the first working day after such work is commenced.
