REQUEST FOR <br />COUNCIL ACTION <br />CITY COUNCIL MEETING DATE: <br />JUNE 3, 2013 <br />TITLE: <br />CLERK OF COUNCIL USE ONLY: <br />APPROVED <br />CONTRACT INCREASE TO ADD ? As Recommended <br />STREETLIGHTS TO FIRST STREET ? As Amended <br />BRIDGE REPLACEMENT OVER THE El Ordinance on 1St Reading <br />? Ordinance on 2"d Reading <br />SANTA ANA RIVER (PROJECT NO. ? Implementing Resolution <br />061723) ? Set Public Hearing For_ <br />/ CONTINUED TO <br />FILE NUMBER <br />RECOMMENDED ACTION <br />Increase the contract with Powell Constructors, Inc., for the construction of the First Street <br />bridge replacement over the Santa Ana River by $250,000 for a total estimated contract amount <br />of $8,065,000, and authorize the City Manager to execute change orders in an amount not to <br />exceed the authorized contingency. <br />DISCUSSION <br />On March 21, 2011, the City Council awarded a construction contract for the First Street bridge <br />replacement over the Santa Ana River to Powell Constructors, Inc., in the amount of $6,010,329 <br />plus a contingency amount of $1,202,066, totaling $7,212,395. On January 17, 2012, the City <br />Council approved an increase of $602,605 which raised the contract total to $7,815,000. <br />The additional costs were related to a significant redesign of the bridge foundations that <br />eliminated conflicts with interfering power lines, resulting from the inability of the utility company <br />to de-energize and relocate its lines. The restriction of constructing the bridge one-half at a time <br />and only during the dry season (six months), as determined by the Orange County Flood <br />Control District, caused scheduling delays that also affected contract costs. Other extra costs <br />were attributed to added enhancements to the bridge, including architectural details to the <br />railings, erecting sound walls, and for general unforeseen underground conditions. <br />Fortunately, due to unpredictability of the highly competitive construction market, the original <br />construction bids were significantly lower than the engineer's cost estimate. That resulted in <br />making additional grant funds available to the project for eligible scope expenditures. Even with <br />major redesign efforts and cost increases to the project, approximately $500,000 in grant <br />funding is still available for this bridge construction project. <br />23A-1
