Mayor and Council Members Council Meeting of repruary's, I U10 SUBJECT: APPROVAL OF CHANGE ORDER NO. 1 IN THE AMOUNT OF $35,000 TO THE CONTRACT WITH KRIEGER AND STEWART FOR THE DESIGN OF THE 2 MGD WWTP EXPANSION AND RENOVATION PROJECT; AND RE -AFFIRM THE BID AWARD TO KRIEGER AND STEWART IN THE AMOUNT OF $700,000 FOR CONSTRUCTION MANAGEMENT DISCUSSION/ANALYSIS: Change Order No 1 in the Amount of $35,000 for Bid Preparation and Award: Due to time constraints within the RWQCB schedule, staff requested Krieger and Stewart to provide the following assistance to the City beyond their scope of work: 1. Bidding document reproduction ($9,000) 2. SRF loan coordination during bidding process and award ($6,000) 3. Design and prepare plans and specifications for the replacement of the digester cover ($20,000) Plant No. 1's digester cover was inspected and found to be unsafe due to structural damage resulting from age. In reviewing the estimated construction cost ($400;000), staff requested Krieger and Stewart to add the digester cover to the expansion and renovation; plans- and specifications as a bid alternate. By adding the digester cover to the overall project will save the City money by cutting the cost of the design of the plans and specifications ($50,000), bidding documents and construction mobilization costs. The contract originally approved by Council on February 5, 1991 included construction management (20% of the cost of the project). The project is estimated to take 18 months to complete, and the construction management will require an inspector to be on-site the entire time the work is being performed, in addition to construction engineering services such as: surveying, soils/materials testing, start-up and testing of facilities, negotiation of change orders and claims, maintaining > records for the SRF loan, and preparation of the project certification report for the SRFban. The proposed cost of $700,000 is a little less than 10% of the estimated project cost ($7.6 million). Page 2 of 3 Agenda Item No.;
