Keith Van Der Maaten, E., Public Works and Utilities Director @r Prepared by: George Al arez, P.E., T.E., City Engineer/ Traffic ngineer DATE: June 17, 2014 SUBJECT: Consideration for Ratification of Change Orders Nos. 3 and 4 and Approval of Change Order No. 6 for the Del Obispo Street Widening from Alipaz Street to Paseo Adelanto Project STP -5372 (011) (CIP 07107) (Peterson-Chase General Engineering Construction, Inc.) RECOMMENDATION: By motion, ratify Change Order Nos. 3 and 4 in the amounts of $227,349, and approve Change Order No. 6 in the amount of $109,140 for a total amount of $336,489 for the Del Obispo Street Widening from Alipaz Street to Paseo Adelanto Project with Peterson-Chase General Engineering Construction, Inc. EXECUTIVE SUMMARY: On March 1, 2011, the City Council awarded a Construction Contract in the amount of $3,453,842.46 to Peterson-Chase General Engineering Construction, Inc. for the Del Obispo Street Widening Project. During construction of the bridge, numerous change orders were required to complete the project due to differing existing site conditions from the design plans. On April 3, 2012, the City Council approved a contingency to the budget in the amount of $270,000 for Change Order Nos. 1 and 2 (Attachment 1). On November 12, 2012, the City Council approved a second contingency to the budget in the amount of $63,525 for Change Order No. 5 (Attachment 2), which related to the Trabuco Creels Bridge Approach Repair Project (CIP 07109). To date, a total of $333,525 has been authorized for contingencies on this project. City Council Agenda Report June 17, 2014 Page 2 of 4 The actual cost of Change Order Nos. 1, 2 and 5 is $150,213. Only $150,213 of the $333,525 in authorized contingency has been used for Change Order Nos. 1, 2 and 5, leaving a contingency balance of $183,312. This contingency fund balance is insufficient to cover Change Order Nos. 3, 4 and 6 in the amount of $336,489. An additional $153,177 of contingency is needed to approve Change Order Nos. 3, 4 and 6. Staff recommends that the City Council ratify Change Order Nos. 3 and 4. Change Orders No. 3 and 4 (Attachment 3) were required to provide bridge structural reinforcement for the sidewalk totaling $227,349. Furthermore, various work order changes were required to complete the contract work, which has been summarized within Change Order No. 6 (Attachment 4) in the total amount of $109,140. Staff also recommends that the City Council approve Change Order No. 6 in the amount of $109,140. The bid line item reduction in the amount of $306,053 is due to the fact that the Change Order Nos. 1-6 eliminate or reduce the work shown in the original bid item. The summary of the Contract Change Orders and the status along with the reduction are included in the Table below: Change Order Status Amount Contract Amount NO./Line Item Contract Redaction $3,453,842 1 Approved $6,713 $3,460,555 2 Approved $85,750 $3,546,305 5 App roved $57,750 $3,604,055 3 Unap roved/Rati $193,173 $3,797,228 4 Unapproved/Ratify $34,176 $3,831,404 6 Una roved $109,140 $3,940,544 Line Item Reduction Unapproved (Notice ($306,053) $3,634,491 �of Completion) Final Contract Amount $3,634,491 DISCUSSION/ANALYSIS: The Del Obispo Street Bridge Widening from Alipaz Street to Paseo Adelanto STPL- 5372 (011) (CIP 07107) project consists of widening between Alipaz Street and Paseo Adelanto and widening the west side of Paseo Adelanto south of Del Obispo Street. Construction work includes bridge widening, concrete railing, Trabuco Creek Channel reconstruction, utility construction, landscaping and irrigation, and traffic signal modification. The Del Obispo Bridge over Trabuco Creek was originally built in the 1930s with some additional modifications. The lack of record drawings from the County of Orange and Caltrans who were involved in the design, resulted in various unforeseen conditions that were discovered during construction, which resulted in the following Contract Change Orders: City Council Agenda Report June 17, 2014 Page 3 of 4 1. Change Orders Nos. 1 and 2, in the amount of $92,463, increased the number of strands of the bridge girders and added coating for the sheet piles. 2. Change 'Orders Nos. 3 and 4, in the amount of $277,349, demolished and constructed the existing bridge north overhang to support vehicle live load and extended the width of the new bridge by 10 inches. 3. Change Order No. 5, in the amount of $67,750, repaired the erosion under the cantilever ends of the existing bridge. 4. Change Order No. 6 in the amount of $109,140, completed potholing of various underground utility lines to verify their location, revised several construction items .to accommodate field condition, provided night labor for construction of the new waterline, and other items of work in order to conduct work during non-peak traffic hours, and provides a new bridge joint seal between the existing and new bridge deck FISCAL IMPACT: The Fiscal Year 2013-2014 budget for CIP 07107 is $1,640,140. Current funding and expenditures are summarized as follows: Expenditures Project Budget Current Fiscal Year 2013-2014 Budget $1,640,140 Expenditure as ofV Ay 31, 2014 507,913) Amount Remaining $1,132,227 Total Amount for Change Orders 1-6 ($486,702) A roved Contract Contin jency To Date $333,525 Remaining Contingency Amount to be Approved to ($153,1 Fund Chan e Orders 3, 4, and 6 Project Budget Remainin $979 050 As shown above, the fund balance is adequate to cover the shortfall of $153,177 to ratify Change Order Nos. 3 and 4 and to approve the Change Order No. 6. Therefore, staff is requesting ratification of Change Order Nos. 3 and 4 in the amounts of $227,349, and approval of Change Order No. 6 in the amount of $109,140, for a total amount of $336,489. The remaining fund balance of $979,050 will fund the additional contingency of$153,177. ENVIRONMENTAL IMPACT: The City's Environmental Administrator completed a preliminary review of this project in accordance with Section 15061 of the California Environmental Quality Act Guidelines. Based on the review, the Environmental Administrator has Prepared Mitigated Negative Declaration for the project.
