(A) Construct sheeting, shoring and bracing to hold walls of excavation where shown on plans or at other locations, as required by any governing state or federal laws, to provide safety for working, to protect existing utilities or structures or to permit construction in the dry.
(B) If wood sheeting is driven below the level of the pipe, it shall be cut off and left in place to a level of five feet below the finished grade. Steel sheeting shall be pulled except where shown on the plans. When a movable trench shield is used below the spring line of the pipe, it shall be lifted prior to any movement to avoid pipe displacement.
(C) Payment for sheeting, shoring and bracing shall be incidental to the utility installation, unless it is set forth as a separate bid item.
