Director of Ge~ Services ~ ..L-J.- City Manager Jf (4/5thsVote:Yes_Nol) SUBMITTED BY: REVIEWED BY: On March 7, 2006, the City Council approved Resolution No. 2006-064 (Attachment A), which awarded a base contract in the amount of $55,440.00 to MJC Construction for the "ADA Pedestrian Ramps, Intersection of First Avenue and Kearney Street, in the City of Chula Vista, California (CIP No. STL-317 A)" project. During the course of said project construction, staff approved Change Order No.2 (Attachment B), which added an item of work and adjusted the quantities of various items of work from what was originally proposed for the project at the time of award. By doing so, construction was facilitated and an overall improved project was obtained at the completion of construction. It should be noted that adding items of work and/or adjusting quantities during the course of construction is a typical event that occurs when field conditions observed warrant such modifications to what was originally planned. These changes and/or additions are typically paid from the contingency funds approved at the time of project award and are approved at the staff level. At times, however, change orders exceed the limitations of staff level (Director of Public Works) approval solely and require City Council ratification in accordance with City Council Policy No. 574-01. Change Order No.2 is for adding an item of work not originally included in the project design and for adjusting the quantities for several items of work originally included with the project; all of these actions were necessary to complete the project in accordance with City standards and to provide for a timelier and improved project outcome. Approval of tonight's resolution will ratify staffs action of approving Change Order No.2 for said project, valued at $7,037.00, in accordance with the City Council Policy No. 574-01. RECOMMENDATION: That Council adopt the resolution. BOARDS/COMMISSION RECOMMENDATION: Not Applicable 9-1 Page 2, Item ~ Meeting Date 8/01/06 DISCUSSION: Proiect Back2round The City of Chula Vista, in recognition of problems faced by physically challenged residents, has established an on-going program to improve existing sidewalk facilities that lack pedestrian ramps. The "ADA Pedestrian Ramps, Intersection of First Avenue and Kearney Street, in the City of Chula Vista, CA (STL-317 A)" project primarily involved the construction of Americans with Disabilities Act compliant pedestrian ramps at the "T"-intersection of First Avenue and Kearney Street. Per the formal bidding process, staff invited contractors to submit proposals for the project. On February I, 2006, General Services Department staffreceived six (6) bids; the lowest responsive bid received was from MJC Construction. Per Resolution 2006-064 (Attachment A), Council awarded a base contract in the amount of $55,440.00, awarded an Additive Alternate I contract in the amount of $7,110.00, and approved construction contingencies in the amount of $6,755.00. Chan2e Order No.1 During project construction, staff decided to increase the footing width and depth of the proposed gravity retaining wall associated with the project. This modification to the existing design was so that the overturning forces associated with the wall were better mitigated. The value of Change Order No. I was $2,600.00 and was approved by the Director of Public Works and did not require City Council ratification per City Council Policy No. 574-01. Chan2e Order No.2 During the course ofproject construction, staff added an item of work and adjusted the quantities of various items of work from what was originally proposed for the project at the time of award. The additional item of work added included the installation of a stemwall and landscape biobarrier adjacent to a portion of the newly constructed sidewalk. This additional work item facilitated the grading included with the proj ect and provided future protection for the new sidewalk against invasive tree roots. The items of work originally included with the project that had the quantities adjusted included the following: asphalt concrete pavement, crushed aggregate base, sidewalk, curb and gutter, driveway area, and cross gutter area. These items were all greater than what was originally estimated with the exception of the cross gutter area. The net increase in project costs with the addition and quantity adjustments for Change Order NO.2 (Attachment B) was $7,037.00. It should be noted that adding items of work and/or adjusting quantities during the course of construction is a typical event that occurs when field conditions observed warrant such modifications to what was originally planned. These changes and/or additions are typically paid from the contingency funds approved at the time of project award and are approved at the stafflevel (Director of Public Works). At times, however, change orders exceed the limitations of staff level approval solely and require City Council ratification in accordance with City Council Policy No. 574-01. 9-2 - Page 3, Item ~ Meeting Date 8/01/06 Therefore, staff recommends that Council ratify City staffs action on approving Change Order No.2, valued at $7,037.00, with MJC Construction to complete the "ADA Pedestrian Ramps, Intersection of First Avenue and Kearney Street, in the City ofChula Vista, California (CIP No. STL-317 A)" project.
