Background: On September 20, 1999, the City entered into a contract with Holland-Lowe Construction, Inc.— Rehabilitation of Pavement on Highland Avenue--Route 259 to Waterman Avenue. Due to delays regarding the Highland Street Tree project, construction could not start until April 17, 2000. Change Order No. One in the amount of $57,928.00 for trenching, backfilling, restoration of pavement, and installation of irrigation system between "E" Street and Sierra Way, was approved by the Mayor and Common Council on May 1, 2000. Change Order No. Two in the amount of$4,350.00 for additional sidewalk needed to match up with the new handicap access ramps to provide a smooth handicap accessible transition to the existing sidewalk, was approved by the City Administrator on June 7, 2000. Subsequently, site conditions were encountered which required further modification of the design as described below. Item Description Increase 1 Increase to compensate contractor for cost to complete the Base $14,691.78 Paving of Waterman Intersection Additional cost of items 3, 5 & 6 (Original Bid—Asphalt 2 Products) due to oil cost increase between September 20, $12,050.22 1999 and June 2000 Additional cost to add 3/8" Dense Fine Mix for leveling 3 course. Cost is based on Time and Material. $64,942.13 4 Increase due to addition of 21 more traffic signal loops at $ 3,948.00 intersections along the length of the project. 5 Reduction in Rubberized Asphalt Concrete Pavement $(69,327.60) Net Amount of Change Order No. Three $26,304.53 - 2 - JUSTIFICATION Item 1: The intersection of Waterman Avenue and Highland Avenue was originally included in the project but was deleted because Public Services Department had a project to rehabilitate Waterman Avenue which covered the same area. When Public Services staff became aware they would be unable to complete the rehabilitation of the Waterman/Highland intersection, it was decided to complete the work as a part of this project as originally intended. Upon completion of grinding of the existing pavement at the intersection of Waterman Avenue and Highland Avenue, it was discovered that the grinder had cut into a layer of"open graded" asphalt which had been placed many years ago. This "open graded" asphalt layer raveled badly under traffic creating a significant amount of dust and an unsuitable driving surface even for the one week period between grinding and the scheduled paving with rubberized asphalt pavement. The contractor agreed to place a 1/2 inch thick leveling course of 3/8 dense fine graded regular asphalt concrete pavement to provide a suitable driving surface. The contractor agreed to perform this work on a time and material basis, in accordance with Section 3-3 "Extra Work" of the Standard Specifications. Therefore, the amount shown is the actual cost for the Contractor to accomplish this work plus reasonable markup and profit. Item 2: The Contract for this project was awarded on September 20, 1999, based on a bid provided by the contractor based on pricing of asphalt pavement at the time the bid was placed. Due to delay in completing the Highland Streetscape project, the "Notice to proceed" had to be delayed until April 17, 2000. After negotiations with staff, the contractor agreed to the delay with no other associated costs except for increases in the cost of paving oil which goes into "tack" and"asphalt pavement"used in the project. Item 3: Upon completion of grinding of the existing pavement between Sierra Way and Arrowhead Avenue it was discovered that the grinder had cut into a layer of "open graded" asphalt which had been placed many years ago by Caltrans. This "open graded" asphalt layer raveled badly under traffic creating a significant amount of dust and an unsuitable driving surface even for the one week period between grinding and the scheduled paving with rubberized asphalt pavement. The contractor agreed to place a % inch thick leveling course of 3/8 dense fine graded regular asphalt concrete pavement to provide a suitable driving surface. The contractor agreed to perform this work on a time and material basis, in accordance with Section 3-3 "Extra Work" of the Standard Specifications. Therefore, the amount shown is the actual cost of the Contractor to accomplish this work plus markup and profit. Item 4: Item I 1 "Install Traffic Detector Loops" called for a total of 50 traffic detector loops to be replaced as part of the project. To facilitate the grinding, the connecting wires to 33 additional loops had to be cut bringing the total number of loops needing to be replaced to 83. In accordance with Section 3-2.2 "Payment" of the Standard Specifications, authority is given to pay up to 125% of the original bid quantity for Item 11. Therefore, payment can be made without change order for a total of 50 x 1.25 = 62 (rounded down) loops leaving 21 loops to be paid under this change order. - 3 - Item 5: The cost of Items 1 and 3 is partially offset by a reduction in the cost of Rubberized Asphalt Concrete Pavement used in the final paving on the project.
