DATE: TO: FROM: PREPARED BY: SUBJECT: ITEM NO. 05 STAFF REPORT NOVEMBER 16, 2010 HONORABLE MAYOR AND CITY COUNCIL ROD FOSTER, CITY MANAGER/GENERAL MANAG] JAMES EARHART, INTERIM UTILITY SERVICES DIRECTOR EMERGENCY SEWER REPAIR CONTRACT WITH ROSS A. GUY & SON, INC. RECOMMENDED ACTION Staff recommends that the City Council acknowledge the City Manager's declaration of an emergency pursuant to Colton Municipal Code Section (CMC) 3.08.130 (a) and approve The First Amendment to the existing contract with Ross A. Guy & Son, Inc. to add additional funds in an amount not -to -exceed $85,665 for the emergency sewer line repair on Coburn & Olive. 2. It is recommended that the Colton Utility Authority Board review, ratify and to the extent necessary, direct the City Council to take the above action(s). GOAL STATEMENT The proposed action supports the Council's goal to operate a safe and sanitary sewer system. BACKGROUND The collection system sewer pipe was built with non reinforced concrete pipe. This type of pipe can be impacted by hydrogen sulfide gas build up which occurs naturally in collection system pipes. This type of pipe is no longer used in sewer construction. ISSUES/ANALYSIS At times, emergency replacement of the sewer pipeline is necessary. Ross A Guy & Son, who is very familiar with the City's sewer lines, was called in for a recent emergency sewer line repair. The collapsed pipe was located where Coburn joins Olive Street. This section of pipe was exceptionally deep compared to others in Colton's collection system (18 feet to the top of the pipe). In order to comply with OSHA and the safety of the contractor, the installation of large metal shields were necessary. Above the Sewer pipe being repaired were other utilities, mainly Gas and Water. This made it necessary to install several smaller shields and the shields had to be lowered as the excavation took place. Minimal traffic closure was necessary during the day, and
