Staffreport
SUMMARY AND RECOMMENDATIONS
This contract provides for the application of preventive maintenance treatments on various streets in the 2012 and 2013 Asphalt Maintenance Areas.
Staff recommends award of the construction contract to the lowest responsible bidder, Intermountain Slurry Seal, Inc., in the amount of $1,156,670.90 for the subject work.
BACKGROUND
Street sealing is a maintenance activity that can prolong the useful life of streets that are not significantly deteriorated. The City’s annual street sealing projects typically are located in one of the City’s four Asphalt Maintenance Areas. This contract will cover two Maintenance Areas because it is a combination of work from both fiscal years 2011-12 and 2012-13. These projects are combined because the bids received for the Annual Street Sealing 2011-12 project exceeded the engineer’s estimated cost by 40% and the City Council subsequently rejected the bids at staff’s recommendation.
The 2011-12 and 2012-13 Annual Street Sealing projects will be constructed via two contracts. This bid and contract is for street segments that are scheduled to receive an application of asphalt rubber cape seal in combination with other street sealing treatments. Asphalt rubber cape seal is a specialty item that is performed by few contractors in the area. To maximize the number of potential bidders on the other portions of the work, the asphalt rubber cape seal work was bid independently.
A separate contract was bid for construction by traditional street sealing methods such as slurry seal, micro-surfacing, and scrub seal. The contract for that work will be brought to the City Council separately.
Analysis
A total of two bids were received on February 20, 2013. Intermountain Slurry Seal, Inc. submitted the lowest responsive bid at $725,470.70 for the base bid, the cost of which was used as the basis of award. The pre-bid engineer’s estimate for construction was $886,516.60 for the base bid.
The street sealing unit prices are approximately 30% less than those from the bids for the 2011-12 project that were rejected in September 2012. Funding is available to incorporate all four of the additive bid items into this contract.
Base Bid: $725,470.70
