On August 15, 2023, City Council approved Resolution 23-R-77 authorizing a construction contract with Intermountain Slurry Seal, Inc. for $190,000.00 and a not to exceed amount of $195,000.00 for the 2023 SPAM Resurfacing project.  The construction contract was for applying a slurry seal to the surface of some streets in the Ashley Place subdivision and on Beck Street.  The streets in the Ashley Place subdivision were streets that had been removed form the previous slurry seal project in order for that project to stay within budget.

Since the project was fairly straight forward, Staff did not anticipate needing the typical 10% contingency for this project.  Reducing the contingency for this project allowed for more funding to be applied to the other street projects (Windy Meadows Overlay and Trainer Hale Repairs) undertaken at the same time.

Once the slurry seal was completed, the final quantity of slurry seal exceeded the plan quantity by about 17 tons (approximately 3.6%).  The overage was due to the cul-de-sacs and “looped” street segments in the project having more overlap than originally estimated.  The overage also exceeded the $5,000 contingency amount approved for the project.  An additional funding allocation of $1,616.25 is needed to fully fund the overrun in the slurry seal quantity.

The Windy Meadows overlay project has been completed and the total construction cost came in slightly under the contract amount.  The difference between the actual cost and contract amount (approximately $6,000) and the contingency for the Windy Meadows Project (approximately $21,000) is more than sufficient to cover this overage.

The completed slurry seal provides a new driving surface for the streets and helps prevent moisture intrusion, preserving the existing pavement section.  This increases the service life of the streets.  The proposed increase int eh not to exceed amount provides for the full payment of the actual costs to complete the slurry seal.
