STAFF REPORT Public Works Services Department DATE: May 17, 2011 TO: Mayor and City Council FROM: Tom Tait, Public Works Services Director Prepared by: Ken Herman, Deputy Public Works Services Director Tiffany Lee, Associate Civil Engineer SUBJECT: AUTHORIZE THE CITY MANAGER TO EXECUTE A CONTRACT WITH DOWNING CONSTRUCTION, INC. FOR THE WATER MAIN REPLACEMENT PROJECT IN THE AMOUNT OF $368,929 Recommendation: Approve SUMMARY The City of Arcadia's Water Main Replacement Program is designed to replace aged and deteriorating water main pipes throughout the City's water distribution system. The water main replacement project identified as a part of the 2010 -11 Capital Improvement Program (CIP) includes the replacement of the water main, fire hydrants, and the installation of additional fire hydrants on Santa Maria Road and Louise Avenue north of Rodell Place. The replacement of the existing cast iron water mains with ductile iron pipes will lessen the potential for future water main breaks and increase the fire flow in the City's water distribution system. Staff recommends that the City Council authorize the City Manager to execute a contract with Downing Construction, Inc. for the 2010 -11 Water Main Replacement Project, in the amount of $335,390 and issue a purchase order for the contract amount plus 10% contingency, totaling $368,929. DISCUSSION The 6 -inch cast iron water mains along Santa Maria Road and Louise Avenue were installed in the 1950's. Recently, City crews have frequently made emergency repairs to the water mains at these locations due to the age and material of the pipe. Cast iron material was a common pipe material due to its strength and corrosion resistance; however it is brittle and susceptible to leaks therefore limiting its durability and reliability. Regular pressure fluctuations combined with minor geological movement Page 1 of 3 Mayor and City Council May 17, 2011 and settlement can cause cracks that eventually result in catastrophic failure. Ductile iron, which replaced cast -iron as the industry standard for water pipe, has the corrosion resistance and strength characteristics of cast iron, but can tolerate more movement or deflection without breaking. The proposed project will replace the existing 6 -inch cast iron pipes with 8 -inch ductile iron pipes, which will lessen the potential for future water main breaks and improve water flow in the pipes, which will improve the overall reliability of the City's water system in the event of a catastrophic event. The project will also replace under -sized fire hydrants and install additional new fire hydrants to meet current fire protection requirements A Notice Inviting Bids was published in the adjudicated paper and bid packages were acquired by area contractors.
