FINANCIAL STATEMENT Staff recommends $28,600 be transferred from the 2017/18 Annual Slurry Seal of Various Streets Project (CIP No. 18504), and $13,630 from City Parking Lots — Resurfacing Project (CIP No. 17424) increasing the total 2016/17 Annual Slurry Seal of Various Streets Project (CIP No. 16504) budget from $535,000 to $577,230. A full breakdown of all project costs is shown in Attachment 1. BACKGROUND The City of Pleasanton has an extensive pavement preservation program that annually resurfaces city streets. There are two main type of projects: an annual slurry seal project that installs an application of slurry seal used to rejuvenate pavement surfaces that are in good condition, extending the useful life, and an annual resurfacing project that reconstructs streets with a new layer of asphalt paving. On June 6, 2017, City Council awarded the Annual Slurry Seal of Various Streets Project (CIP No. 16504) to American Asphalt Repair & Resurfacing Company, Inc. for the low-bid amount of $484,575. The project consisted of applying slurry seal coating to approximately 2,607,000 square feet of pavement on sections of 85 city streets. As part of the award, City Council also authorized the Director of Engineering to approve and execute changes orders up to a not-to-exceed amount of $50,000 (the remaining project budget) for unforeseen conditions discovered during construction. The project began construction in the fall of 2017, but due to an early cold snap and rain causing poor conditions for slurry seal installation, the project went into winter suspension. Work resumed in June 2018 and continued through July. During the 2018 slurry placement, very hot weather occurred that caused the slurry seal material to remain soft and malleable longer than expected. This resulted in normal vehicle traffic causing excessive scarring and blemishing of the newly sealed street surfaces. Because the material stayed malleable for so long, the City and the contractor had numerous specialists review the streets and test the material. The results indicated that the material was within specification, and the specialists recommended providing more time for the material to cure. The material did finally cure when the weather cooled toward the fall of 2018, but the scarring of the street surface had already occurred. The scarring is aesthetically unpleasing, but does not change the serviceability of the slurry sealed surface. There have been four change orders to date executed on the project, with two more change orders anticipated. The four executed change orders total $35,554. The change orders increased the project cost for additional pavement striping required, adding Tanager Court to be sealed, adding Augustin Bernal Park parking lot to be sealed, and a specification allowed adjustment to contract price based upon oil price escalation. The two anticipated change orders remaining total $49,659. This includes $42,156 to install 324,275 square feet of Type I slurry in the Valley Trails area and Sandpiper Way, and $7,503 as a balancing change order for the actual measured constructed quantities compared to the estimated quantities used in the bid documents. These costs are also shown on Attachment 1 . There are also three other costs on the project that are shown on Attachment 1 . Page 2 of 3
