Also pointing to consolidation being a near surface issue is the deeper manholes are not showing signs of settlement at the their base, which actually causes the relatively rigid manhole cone structure to appear as though it is rising out of the street, when in fact it is staying stable as the soil consolidates around the manhole cone. This phenomenon is also impacting ride quality. The Engineering Department outlined a scope of work with the Traffic and Streets Divisions to restore the roadway to a safer operating condition, but the work will not restore the roadway to the original grades. Some areas of the street have recessed several inches below the original grades and leveling the streets to the original grades would cause the asphalt to be at or above some of the existing curbs. The work will include approximately 18,000 square feet of base repairs and 600 tons of hot mix asphalt leveling. The work does not include overlaying the entire street and only addresses the most severe areas. Bidding Process Staff is recommending this work be accomplished prior to the upcoming rainy season to prevent ponding on the roadway, and the potential dangers associated with vehicle hydroplaning. Proposals were requested from paving contractors that have active contracts with City including Teicherts (Operations Services Department on-call paving contractors), Goodfellow Bros., LLC, Inc. and Bay Cities Paving & Grading. Teicherts and Bay Cities Paving & Grading stated they do not have the capacity to complete the work this year and declined to submit a proposal. Goodfellow Bros., LLC, Inc., who provided a proposal of $232,072, is currently working on the City's OBAG II — Resurfacing of Various City Streets Project, CIP No. 17508, which includes federal funding. Since the project includes federal funding administered by Caltrans, staff contacted Caltrans about including the additional work as a change order to the contract with Goodfellow Bros. Caltrans indicated that the additional work would need a federal National Environmental Policy Act (NEPA) review prior to awarding the change order. While they did not see an issue arising from a NEPA review, they recommended not adding the additional work to the project as a change order if the goal is to complete the project before the rainy season, as a NEPA review would delay the work well into and perhaps beyond the rainy season. The Engineer's Estimate for this work is $200,000. Since the one proposal received is above the Engineer's Estimate, staff contacted several contractors that have performed paving projects with the City in previous years to see if they had the capacity and interest in the work. An additional proposal for $235,000 was received from O'Grady Paving, who performed emergency work on Longview Lane last year after a waterline failure. Based upon the two bids, and since Caltrans advised against issuing a change order to the federally funded OBAG contract, staff is now recommending that City Council award a contract to Goodfellow Bros., LLC, Inc. in the amount of $232,072 for the urgent repairs. The West Las Positas Boulevard Street Settling Repair Reserve has a current balance of $425,230 which is sufficient to fund the urgent repair work. Please note this is Page 4 of 6
