Based on the City Council's direction, staff rejected the contractor bids for the Project due to a Contractor protesting information not included on another Contractor's bid. Since the construction bids for the Project have been rejected, we have prepared the following to rebid the Project with the associated modifications identified during the previous bidding process and additional items of work as described herein. We will prepare modifications to the plans and contract documents for the project plans to include the bidder questions and additional specification language included in the bid addendum, together with the following additional items of work: Perform engineering analysis of the feasibility of locating and constructing a 12 inch recycled water pipe from the Mazzoni Street intersection westerly within Brush Street, across the State Street intersection and westerly within Low Gap Road to five feet beyond the proposed improvements. Locating the proposed recycled water main will require analyzing the location and depths of existing water, sewer, gas, storm drains, telephone, and underground power conduits to maintain Title 22 separation from the existing water mains and clearance with other utilities. Meet with the City of Ukiah staff to discuss the recycled water main feasibility. Add elements to the traffic signal system per comments from the City Electrical Department. Obtain additional sewer depth data to be added to the street profile of Brush Street for sewer lateral construction. \ \Willits\Projects\2016\416056-N.Statelntx\100-South-RofW-Br\PUBS\Corr\20170119_ContractAmendLtr.doc Mr. Rick Seanor North State Street Contract Amendment January 19, 2017 Page 2 • Prepare a new plan and profile sheet, and trench details for the recycled water main construction. • Prepare a new specification section for the recycled water main construction. • Modify the sheet numbering and index to add the new plan and profile, and trench details. • Prepare revisions to the Notice to Bidders document. • Prepare revisions to the Bid Schedule. • Prepare miscellaneous revisions to the contract documents to revise bid dates, order of work, and specifications. • Prepare an updated engineer's opinion of cost for the construction project. • Submit a set of plans and contract documents for review and comment by City staff. • Prepare a new set of .pdf plots of the project plans, and a .pdf file of the contract documents after performing final revisions and provide a digital copy to the City for posting to their construction bidding website. • Print a new set of original full size updated plans, with the revisions and additions. • Obtain a wet signature on the project plans and contract documents. • Print and bind three new sets of contract documents for submittal to the City of Ukiah. • Provide 10 sets of printed full size plans to City of Ukiah. • Provide assistance to City staff answering technical questions and preparing any addendums during the bidding process.
