now agreed to a new alignment, readjusting the lane widths and bike lane widths, which <br />will relocate all the proposed designed curb and gutter locations and expand the limits <br />of the improvements necessary to make the lane transitions to the intersection. Quincy <br />is in the process of completing an updated DSDD to be submitted to Caltrans. Upon <br />approval of the DSDD, the redesign of the plans and specifications will resume. Waiting <br />for the DSDD approval by Caltrans will likely delay the project a several months, but due <br />to the numerous changes requested by Caltrans after previously signaling approval of <br />the design concept, it is thought to be the most prudent to accept the delay and wait for <br />official DSDD approval before proceeding with the final design. <br />The additional fees to be paid to Quincy cover the cost of the numerous iterations of <br />alignments and time spent working to meet the varying Caltrans comments to date, <br />cover the cost of re -design and preparation of new plans, as well as cover the cost of <br />the preparing the DSDD. Based on the new alignment, that also expands the limits of <br />construction to the south, the new plans will also require detailing of additional curb and <br />gutter, additional signal and lighting work, survey work, and potholing. <br />In addition, the Quincy work will also include a vibration study and monitoring for the <br />building at 6111 Johnson Court, where the improvements will be 4 feet from the existing <br />building. The work has been added due to concerns raised by the building owner when <br />staff met with him regarding the project and its proximity to the building. It is expected <br />that the vibration study and monitoring will show the project does not exacerbate <br />existing conditions. The study will likely be useful to satisfy the building owner's <br />concerns, but also it may also be helpful in determining construction methods when <br />working in close proximity to the building. <br />Budget <br />The current Capital Improvement Program budget includes $2.78 million to fund the <br />design and construction of the Hopyard Road and Owens Drive Intersection <br />Improvements, CIP No. 15525. The total design costs for this project will be $310,127, <br />which includes the original contract amount, this amendment, and previous task <br />authorizations charged to the project budget. <br />The total cost of the project (design and construction) is estimated at $3 million based <br />on the expanded intersection, leaving a potential project shortfall of $220,000. This will <br />require an additional budget allocation prior to construction. However, the shortfall is <br />currently an estimate, so a budget change is not requested at this time. Staff <br />recommends submitting the DSDD, obtaining Caltrans approval, proceeding with the <br />design and construction documents, obtaining Caltrans permits, and bidding the project. <br />The project will then be presented to City Council with a recommendation to award and <br />include a budget adjustment, if necessary, based upon the actual low bid received for <br />the work. <br />Page 3 of 4 <br />
