1121.03   TRENCHING, GRADE AND COVER.
   (a)   No trenching or laying of pipe or fitting shall be done until the curb and gutter have been installed or until curb grade stakes have been set. Trench cut stakes may, in certain installations, be substituted for curb grade stakes, but only when approved by the City Engineer or Public Works Director.
   (b)   The contractor shall establish all locations, lines and grades in advance of all work insofar as it is practical. The contractor shall keep the Public Works Director informed a reasonable time in advance of the times and places at which he intends to work.
   (c)   All work during the progress and its completion shall conform to the lines and grades given by the engineer and shall be done in accordance with the drawings and specifications, subject to such modifications as the engineer or City may determine to be necessary during the execution of the work. The main shall have a minimum of forty-eight inches of cover, except at such points where the grade must be adjusted to meet existing conditions or unforeseeable obstacles, and except where otherwise indicated on the plans.
