Change Order #1 June 11, 2001 Page 2 The streets which were deleted from the proposed Bidding Schedule prior to the solicitation of public bids for the 2000-2001 Pavement Rehabilitation Project are as follows: Olive Street From Rancho west to the City Limit/County Pocket Norman Road From Laurel to the north end cul-de-sac Tejon Avenue From Olive to the north end cul-de-sac Sycamore Avenue From Valley Blvd to the south end The additional cost for adding the streets on Change Order #1 is $39,253.42. One of the portions of the existing project is the rehabilitation of the parking lot at the Ken Hubbs Little League Ballfield in Max Lofy Park. The City's Fire Station No.1 is located adjacent to the Ken Hubbs parking lot; the Fire Department has requested that their adjoining portion of the parking lot and the alley also be rehabilitated. There are obstacles (buildings, utility structures, bleachers, etc) in the parking lot area shared by Fire Station No. 1 and the Ken Hubbs Little League ballfield. Due to these obstacles, the original concept of cold planing to a depth of two inches (2") and replacing two inches (2") of asphalt would involve a very large amount of labor-intensive handwork on the part of the contractor. The machinery used in the cold planing process cannot fit in many portions of the lot due to the locations of the existing structures and other obstacles; the machine cannot get closer than two' to any existing vertical structure. This method of rehabilitation ends up creating an amount of handwork that renders the project cost prohibitive. Staff has met with the contractor (Matich) several times to discuss options for the rehabilitation of this parking lot. The method agreed upon will afford the City the best end result for the minimum outlay of funds. The existing parking lot asphalt will be rubblized (broken down) and then graded in place to be used as a base for the new AC overlay. This method creates a substantially smaller amount of labor- intensive handwork and results in a stronger pavement surface and a longer life for the parking lot. A new drive approach will be added on "E" Street, and two (2) handicap ramps will be installed to insure ADA compliance at the entrance of the alley on 10th Street. The contractor has only a ten-day window beginning June 20, 2001 in which to perform the proposed work without disturbing Little League play. The additional cost for this portion of Change Order #1 is $32,198.00. The City Manager has requested that the alley adjoining Fleming Park (located between "E" Street/"F" Street and 7th Street/North La Cadena Drive) be rehabilitated. The increased cost on Change Order #1 is $4,317.37. The County of San Bernardino recently placed a 2" overlay on several areas (County Pockets) adjacent to the City of Colton. In doing so, any adjustments to the existing manholes and gate valves belongs to the owners of the utilities. The City owns the water lines and sewer lines that pass through the County Pockets. City staff (Utilities) determined that there are twenty (20) manholes and twenty (20) gate valves that need adjustment to meet the new grade of the overlay. The 2000-2001 Pavement Rehabilitation Project — Phase II has lower unit costs for these items than any other contract processed by the City during the previous five (5) year period. Knowing this, the Utilities Department requested that staff
