FOR THE FISCAL YEAR 2017-18 PAVEMENT REHABILITATION PROJECT AS COMPLETE Recommendation: Approve SUMMARY On February 6, 2018, the City Council approved a contract with Hardy & Harper, Inc. in the amount of $1,234,000 for the Fiscal Year 2017-18 Pavement Rehabilitation Project. The terms and conditions of this project have been complied with and the work has been performed to the satisfaction of the Project Manager for a total project cost of $1,254,243.79. This amount reflects the original contract amount of $1,234,000, plus additional quantity changes totaling $20,243.79, or 1.6% more than the original contract amount. It is recommended that the City Council accept all work performed by Hardy & Harper, Inc. for the Fiscal Year 2017-18 Pavement Rehabilitation Project as complete, and authorize the final payment to be made in accordance with the contract documents, subject to retention of $62,712.19. BACKGROUND The Public Works Services Department (“PWSD”) is responsible for the maintenance and repair of approximately 147 mile s of paved streets within the City. As part of the City’s Pavement Management Program , the conditions of all City streets were inspected and rated on a scale of 0-100, with scores below 40 generally being considered a street which has failed. Scores between 40 and 60 are poor/fair in nature. This rating is called the Pavement Condition Index (“PCI”) and it is used to help determine which streets require asphalt pavement rehabilitation . However, PCIs alone do not determine which streets should be rehabilitated; for instance, the City also takes into consideration whether the street has a high traffic volume. Additionally, it is more cost efficient to rehabilitate streets prior to the PCI reaching a poor or very poor condition. Accept 2017-18 Pavement Rehabilitation Project August 7, 2018 Page 2 of 4 Based on the Citywide Pavement Management Program, the following street segments were included in this year’s project: The street segment of Hampton Road from Michillinda Avenue to Glencoe Drive (PCI of 38), Walnut Avenue from Holly Avenue to El Monte Avenue (PCI of 62), Walnut Avenue from El Monte Avenue to the east end of the cul-de-sac (PCI of 39), Delta Lane from El Monte Avenue to the east end of the cul- de-sac (PCI of 39), Fifth Avenue from Duarte Road to Camino Real Avenue (PCI of 22), and Camino Grove Avenue from Sixth Avenue to Eighth Avenue (PCI of 36). A copy of the Project Location Map is attached as Exhibit “A”. DISCUSSION On February 6, 2018, the City Council approved a contract with Hardy & Harper, Inc. for the Fiscal Year 2017-18 Pavement Rehabilitation Project. The work performed involved repairing localized potholes and failed pavement, grinding the edges of the pavement adjacent to the gutters to transition the new pavement to the existing gutter, replacing broken curb and gutter as necessary, and installing new ADA-compliant curb ramps at the intersections. The new pavement surface utilized recycled rubber in the pavement mix to help reduce future cracking and to add strength to the asphalt pavement. The rubber in the pavement mixture also reduces road noise. Following the repairs, the condition of all relevant street sections was raised to a PCI of 100. Following mobilization of the project, additional work was identified as needed, including pavement rehabilitation on Sierra Madre Boulevard from Santa Anita Avenue to Oakwood Drive, and concrete gutter replacement on Live Oak Avenue and El Capitan Avenue. The additional pavement rehabilitation on Sierra Madre Boulevard helped ease school traffic at Highland Oaks Elementary and also raised the street’s PCI from 52 to 100. The gutter replacement on Live Oak Avenue and El Capitan Avenue addressed drainage issues and improved public safety. While this work was not originally anticipated, it was determined to be high priority and was well within the ten percent contingency approved for the project. Additionally, during the course of work, it was discovered that the asphalt thickness on Hampton Road, Walnut Avenue, Delta Lane, Fifth Avenue, and Camino Grove Avenue varied, which resulted in change orders that decreased the amount of work needed.
