§ 907.07  STANDARDS FOR COMPANY WORK; COST OF EMERGENCY WORK.
   (a)   The work of any company shall be first class in every respect. The city shall have the right to insist that all work be performed by competent foreman and workmen and may require that any company employee doing unsatisfactory work be removed. All structures shall be constructed in a workmanlike manner, true to line, grade and dimensions, and of ample strength to withstand all anticipated loads and stresses. The city may require that unsatisfactory structures be rebuilt. Materials shall be entirely suitable for the structures contemplated, they shall be so delivered and stored as to give the least inconvenience to the public and shall be used within a reasonable time after delivery.
   (b)   Excavation for structures shall be so conducted as to keep interference with other uses of streets and public grounds at a minimum and shall be subject to city control as to location and extent. Suitable bridges over trenches at street intersections and at other locations where they are deemed necessary shall be furnished by the company, if required by the city. Excavation, in general, shall be open trench and tunneling shall be permitted only in specific locations approved in writing the by city. Structures of the city or other companies encountered during work shall be called to the attention of the city promptly and all necessary precautions taken to protect them. No such structures shall be disturbed until the authorization of the owner is secured. The city may require such bracing, sheeting, footings and other measures as are deemed necessary to protect structures.
   (c)   Backfilling of trenches shall follow the completion of work as closely as possible. Sand or such other easily compacted material shall be used for backfilling as deemed necessary by the city, together with such puddling, tamping or other methods of compaction deemed necessary to produce a satisfactory subgrade.
   (d)   Trenches and other excavations shall be maintained by the company until the city makes permanent repairs to pavements or structures, it being understood that the city shall make repairs within a reasonable time. If maintenance work is not done promptly or in a manner satisfactory to the city, the city may do such work as it deems necessary and all costs shall be borne by the company.
   (e)   Pavements, curbing, walks, drives and other city structures removed or disturbed during work will be replaced by the city at the expense of the company unless otherwise provided at the time the permit is granted. If the company is permitted to do any part of such replacement work, it must be done under city inspection and in accordance with the standard practice of the city for such work and structures. Pavement base shall be of at least two inches greater thickness than the base removed and the company shall install steel reinforcement if it is deemed necessary by the city. Pavement surface shall be of the same type as the surface removed except by written permission of the city, in general, replaced structures shall be of the greater thickness, strength and durability than the original structures to compensate for possible subsurface settlements or failures, for difficulty in bonding old and new work and for structural weakening due to loss of homogeneity.
   (f)   In an emergency the city may enter upon any work and execute such measures as may be necessary to prevent loss of life, injury to persons or serious damage to property. Any cost rising out of the doing of such emergency work will be a charge upon the company.
