•~ <br />Change Order No. 4 <br />Project Nos. 1780 <br />January 5, 2008 <br />Page 2 <br />REASON FOR CHANGE <br />The Flower Street Bridge is more than 70 years old and accurate as- <br />built information was not available. After demolishing the sidewalk and <br />girder on east side of the bridge, it was discovered that an old <br />underground telephone duct, whose exact location was not shown on the <br />original plans, would interfere with the new girder for the widened <br />bridge. Due to its fragile state and the numerous wires inside, this <br />duct could not be relocated. As a result, the girder had to be revised <br />to a different shape with added reinforced steel to straddle over the <br />duct. The new girder is 160 feet long, 4 feet deep and 6 feet wide. Due <br />to this change, the existing abutment walls at both ends of the bridge <br />could no longer be used to support the new girders. They were <br />demolished and replaced with new walls. <br />AGREED PRICE _ $50,471 <br />FISCAL IMPACT <br />The cost for the change order is estimated at $50,471. Funds are <br />available in the Measure M Turn-back Fund (account no. 32-551-6631). <br />APPROVED AS TO FUNDS AND ACCOUNTS: <br />v` ~~~u ~'~~ ~~ <br />James G. oss Francisco Gutierrez v <br />Executive Director ~~xecutive Director <br />Public works Agency Finance & Mgmt.
