Title
Staff Report for a Resolution Awarding a Construction Contract to Intermountain Slurry Seal, Inc. for the Annual Street Sealing 2012-13 Project, Project No. 2013.0070
Staffreport
SUMMARY AND RECOMMENDATIONS
This contract provides for the application of preventive maintenance treatments on various City streets in the 2012 and 2013 Asphalt Maintenance Areas.
Staff recommends award of the construction contract to the low bidder, Intermountain Slurry Seal, Inc., in the amount of $848,727.40 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 perform work in one of four Asphalt Maintenance Areas. However, the subject contract will perform work in two maintenance areas because it is a combination of work from fiscal years 2011-12 and 2012-13. The two years have been combined because the bids received for the Annual Street Sealing 2011-12 contracts exceeded the engineer's estimated cost by 40%. The City Council subsequently rejected the bids for that project.
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 scrub seal and/or slurry seal. To maximize the number of potential bidders on this work, a separate bid was done for asphalt rubber cape seal work, which is a specialty only offered by a few contractors in the area.
The contract for the asphalt rubber cape seal work will be brought to the City Council under a separate staff report and resolution.
Analysis
A total of five bids were received on February 19, 2013. Intermountain Slurry Seal, Inc. submitted the lowest responsive bid at $551,401.15 for the base bid, the cost of which was used as the basis of award. The pre-bid engineer's estimate for construction was $679,746.28 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 by the City Council in September 2012. Funding is available to incorporate additive bid items A through D into this contract.
