DISCUSSION
On March 23, 2010, City Council authorized the award of the 2009 -2010 Citywide Slurry
Seal Project to American Asphalt South, Inc. The contract provided for the slurry
sealing of various streets in the Harbor View, Newport Hills, Seawind, Spyglass Hill and
Harbor View Hills South communities.

The project encountered 20 days of unforeseen delays during the work due to material
procurement issues with thermoplastic paint. On June 2, 2010 Dupont, one of the few
manufacturers who control the production of this material, informed paint manufacturers
that it was eliminating a significant portion of its productive capacity. These events
coupled with increased demands, particularly overseas, caused a worldwide shortage of
this material. To remedy the thermoplastic paint shortage, City staff directed the
contractor to apply final striping and markings with several coats of regular paint.
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: $479,000.00
Actual cost of bid items constructed: $437,591.09
Total change orders: $0.00
Final contract cost: $437,591.09
The final overall construction cost, without any change orders was approximately 5%
percent below the original bid amount. Although all planned streets (except Ford Road,
Mesa View Drive, Prairie Road and portions of Newport Hills Drive West) were slurry
sealed in accordance with the contract, the final contract cost was lower than the
awarded amount as the actual square footage covered (3,539,901 square feet) was less
than the estimated amount (4,000,000 square feet) stated in the contract. In addition,
Ford Road, Mesa View Drive, Prairie Road and portions of Newport Hills Drive West
were not slurry sealed due to a conflict with another city project under construction in
the same area. These streets will be included in the upcoming 2010/11 slurry project
scheduled for spring 2011.
