Discussion: On April 14, 2009 the City Council authorized the award of the 2008 -2009 Citywide Slurry Seal Project to Pavement Coatings Company. The contract provided for the slurry sealing of various streets within the Bay Knolls, Mariners and Dover Shores Communities. The contract has now been completed to the satisfaction of the Public Works Department. A summary of the contract cost is as follows: Original bid amount: $463,100.00 Actual amount of bid items constructed: $445,369.80 Total amount of change orders: $9,850.00 Final contract cost: $455,219.80 The final overall construction cost including three Change Orders was 1.7% percent below the original bid amount. Although all planned streets (except Constellation Drive) were slurry sealed in accordance with the contract, the final contract cost was lower then the awarded amount as the actual square footage covered (3,783,778 square feet) was less then the estimated amount (4,000,000 square feet) stated in the contract. In addition, Constellation Drive was not slurry sealed due to a conflict with another city project under construction in the same area. Constellation Drive will be included in the up- coming 09110 slurry project. The project also had three change orders totaling $9,850 as follows: DS -09 Citywide Slurry Seal - Completion and Acceptance of Contract No. 4086 September 22, 2009 Page 2 Change Order Description Amount 1 Additional striping & raised pavement markers along Highland Dr. $1,650 2 Additional striping & raised pavement markers along Tustin Ave. $4,000 3 Delay due to the construction of a separate city contract within the same area resulting in a second mobilization. $4,200 Total Project Change Orders $9,850 A summary of the project schedule is as follows: Estimated completion date per June 2008 schedule: August 21, 2009 Project award of construction: April 14, 2009 Estimated completion date at award: August 28, 2009 Actual substantial construction completion date: August 6, 2009 All work was substantially completed by August 6, sixteen days ahead of the scheduled completion date of August 28, 2009.

Funding Availability: The awarded contract amount was $463,100 and the approved contingency amount to cover the cost of unforeseen work was $46,000 (10 %).
