full responsibility and control of the repairs. Mueller Pipeline has indicated to staffthat these repairs are at its expense. He noted that stafflooked for a method to expedite the work so that the roadway construction could continue. The method that was selected is an expensive way to do the repairs, but allows for a much shorter time frame. Mueller Pipeline hired a specialty grouting contractor to do the work. As indicated in the staff report, staff's conversations with PG&E have been that it will not release the bonds on this project until staffinforms PG&E that it is satisfied and the repairs are complete. Ms. Ayala shared Mayor Pico's concerns. She asked if this was a special project? Mr. Grubstick noted that this was a new method in Pleasanton. Ms. Ayala wanted assurance that the current failure would not occur on other parts of Vineyard Avenue. Mr. Grubstick believed the construction technique in the roadway sections was different than the work conducted underground. He noted that the contractor was not as careful with its shoring, and the compaction is different. He reported that staff has been observing what has occurred along the roadway and has not seen any subsidence. The only subsidence has been in the off road areas. Staff felt confident with the work that was done in the street, which is where the City inspectors spent most of their time. He pointed out that Kleinfelder was also present in the street area doing the compaction tests. Ms. Hosterman asked if Council should have concern about future subsidence? Mr. Grubstick said no. He mentioned that along this alignment, Mueller Pipeline has agreed to do injection grouting along the entire length of Vineyard Avenue. The first approach was to try and identify where the subsidence had occurred and then repair it. Staff did not want Mueller Pipeline to do so because it did not know where it might occur. After a few areas were opened, Mueller Pipeline agreed that it would extend its repairs along the entire alignment. He indicated that there is an area easterly of the Vineyard alignment, which is through the vineyards, where localized areas have experienced the same type of subsidence. The contractor will be repairing the work in the vineyard area in the spring or summer once it has completed the other work. Mueller Pipeline realizes that the highest priority is to get Vineyard Avenue built. Ms. Hosterman asked if all of the repairs would eventually be made? Mr. Gmbstick said yes. Ms. Hosterman asked if there was any correlation between the subsidence and the safety aspect of the 230kV line? Pleasanton City Council 26 02/03/04 Minutes
