HomeMy WebLinkAbout5/2/2001 - STAFF REPORTS (8) Date: May 2, 2001 To: City Council From: David J. Barakian, City Engineer APPROVE CONTRACT CHANGE ORDER NO. 3 TO GRANITE CONSTRUCTION CO. RECOMMENDATION: That the Council approve Contract Change Order#3 to Granite Construction Co., for a decrease in the contract amount of $12,014.33, for the Mid Valley Parkway Phase III, Ramon Rd. and Gene Autry Trail Traffic Signal and Street Improvements, City Project# 99-13. SUMMARY: During construction of the Mid Valley Parkway Phase III, there were some items of additional work and unforseen costs which were required in order to complete the project. Change Order#3 includes the payment of these items as well as increases and deductions to various bid items. BACKGROUND: City Project# 99-13 (Mid Valley Parkway Phase III, Ramon Rd. and Gene Autry Trail Traffic Signal and Street Improvements), was awarded to Granite Construction Co. by Minute Order#6682 and Agreement#4261. Work on this project began on October 16, 2000 and the Project was complete as of March 20, 2001. During the construction of this project some unforseen circumstances developed for which staff proposes to compensate Granite Construction for additional work and incurred costs. This additional work and costs are as follows: Increases to the Contract Traffic Control/Earthwork Change Order#1 to the contract (which was previously approved by Council on November 15, 2000), consisted of the construction of street improvements adjacent to the Lowes development on Ramon Rd. This change order did not provide for the additional traffic control or earthwork that was necessary. These items were completed at the agreed price of $5,317.62 which was determined by tracking the time and materials required to complete the work Removal of Concrete During the excavation for the widening of Ramon Rd. (adjacent to the old Palm Springs dump site), some large pieces of concrete were discovered. The existence of these concrete pieces is considered to be an unforseen circumstance. This concrete was removed and disposed of by Granite. The total cost for this removal was $490.41 which was determined by tracking the time and materials required to complete the work. V A Change Order No. 3, Granite Construction Co. May 2, 2001 Page 2 Storm Drain Line "D" Obstruction On the night of December 1, 2000, Granite Construction attempted to install Storm Drain Line "D" per plans and specifications. This work required additional traffic controls, equipment and personnel. After work began, a large concrete obstruction was uncovered which could not be removed and prevented the storm drain from being installed per plan. The work was stopped so that the storm drain connection could be re- designed. This obstruction was an unknown condition. This increase of $9,884.43 represents the agreed price for costs associated with the lost night of work. Remaining Increased Costs The remaining increased costs per this change order consist of original bid items that exceeded contract estimates. In most cases these increases are relatively small however, some seem to greatly exceed the original estimate. The reason for this is that there were many bid items that were nearly redundant. Due to the fact that the project took place in two separate rights of way, the bid schedule allowed for two separate standards (CalTrans and City of Palm Springs), which are nearly identical. Where there was a cost advantage to The City, some of bid items were interchanged. For example, the City A2-8 curb and CalTrans A2-200 curb are both an 8" curb with gutter; but there is a cost difference of $1.00 per linear foot. Where these conditions occurred, the bid item which resulted in a savings was used. Therefore, the majority of increases to the various bid items are offset by a decrease to a comparable, more expensive item below. The total cost of increased bid items is $85.545.01. Total Contract Increases = $101,237.48 Decreases to the Contract Various Decreases As indicated above large increases to some of the originally estimated items are offset by decreases to comparable more expensive items. In addition, actual quantities of some items varied from the quantities originally estimated (including cco #1 and cco #2 force account estimates). Due to these reasons, the total net amount of decreases for the project are $113,251.81 Total Contract Decreases = $(113,251.81) The net change order amount = $(12,014.33) Funding for this project is provided by the followings accounts: 134-4498-50133 (Local Measure A MVP Ph-3) and 261-4491-50133 (Reimbursable Mid-Valley Parkway Ph-3). These accounts will be credited respectively. In addition, compensation to the City for a total of $1,539.56 (of the above increases), will be pursued from the Lowes developer due to the net increase of work performed adjacent to that property. ?h Contract Change Order No. 3, Granite Construction Co.

REASONS FOR CHANGES: INCREASES Bid items 5,8,9,10,12,14*,18,19*,21,25,27,31,36* and 37*: Actual quantities placed exceed contract estimates. * indicates that the overage quantities of these items are offset by a decrease in a comparable item below. On this project there were several bid items which were listed by both CalTrans standards, and City of Palm Springs standards which were nearly identical. Where a savings to The City could be identified, these standards were interchanged to utilize the bid item of lower cost. These items constitute the bulk of the project overages above, and are offset by decreases to the comparable item below. For example bid item 14 (Al-6 curb) increased by 1185.5 LF while bid item 16(A1-150 curb) decreased by 1180 LF. By doing this, the net savings on this one particular bid item was $1,097.50. In addition to this substitution, the following substitutions were made: Item 19 for Item 15, Item 36 for item 44 (C.O. #2), and item 37 for item 45 (C.O. #2). New Items Removal of concrete: During excavation for the roadway expansion, Granite Construction exposed some large pieces of concrete which were buried along the North Side of Ramon Road between Gene Autry Trail and San Luis Rey. This concrete was removed and disposed of and the costs indicated above represent the agreed price for this work. Page 3 of 5 84 Storm Drain Line "D" Obstruction: On the night of December 1, 2000 Granite Construction attempted to install Storm Drain Line "D" per plans and specifications. This work required additional traffic controls, equipment and personnel. After work began, a large concrete obstruction was uncovered which could not be removed and prevented the storm drain from being installed per plan. The work was stopped so that the storm drain connection could be re-designed. This obstruction was an unknown condition. This increase represents the agreed price for costs associated with the lost night of work. Traffic Control/Earthwork: Change Order #1 (approved by Council on November 15, 2000), consisted of the construction of street improvements adjacent to the Lowes development on Ramon Rd. This change order did not provide for the additonal traffic control or earthwork that was necessary. These items were completed at the agreed price of $5,317.62 which was determined by tracking the time and materials required to complete the work. DECREASES Bid items 6,7,13,15*,16*,17,20,22,32,33,35,40and 41: Actual quantities placed were less than contract estimates. 1* offsets increased quantities as indicated above) Change Order No. (1) Items No. 6 and 15: Actual quantity placed was less than the Change Order estimate. Force Account (Ramps/Striping): Additional funding was approved on change order No. (2) in order to place handicapped ramps and additional striping. The actual amount of funds required to place these items was less than the change order estimate. Change Order No. (2) Items No. 44* and 45*: Actual quantity placed was less than the Change Order Estimate. (* offsets increased quantities above) Force Account Item: Additional funding was approved on change order No. (2) in order to Adjust the subgrade on Gene Autry Trail. The actual amount of funds required to lower the grade was less than the Change Order Estimate. Four (4) working days will be added to the contract for the completion of additional force account work. The original notice to proceed for this project stated that project time would commence on September 25, 2000. However, due to non availability of signal poles, project time did not actually commence until October 16, 2000. Due to this and in order to accurately account for project time, 14 additional working days will be added to the contract. It should be noted that additional quantities for items 8,9,21 and 22 are being paid for the removal and replacement of a cross gutter and spandrel which was incorrectly placed. This cross gutter and spandrel was placed as part of the work called out in change order No. (1) (adjacent to the Lowe's project), and was incorrectly placed due to an error in surveying/staking. Granite Construction is being paid for the completion of this additional work, and the City is pursuing compensation from the project surveyor (RBF) in the amount of $5,530.00 due to this error. In addition a total of $1,539.56 of the Page 4 of 5 �II above increases will be pursued from the Lowes developer due to the net increase in costs of work performed adjacent to this property. NOTE: No additional markup will be added to any items in this Contract Change Order. All costs Per each item are final. D.
