Ready, City Manager Initiated by: Public Works and Engineering Department SUMMARY Approval of Change Order No. 9 to the McKenna General Engineering, Inc., contract (Agreement No. 5524) revises the total contract amount for construction to $5,175,628.39, an increase of $362,610.08 for additional construction and final bid item quantities associated with the Gene Autry Trail Widening (Vista Chino to UPRR), City Project No. 02-03. RECOMMENDATION: 1) Approve Change Order No. 9 to Agreement No. 5524 with McKenna General Engineering, Inc., in an amount of $362,610.08 for a revised total contract amount of $5,175,628.39 for the Gene Autry Trail Widening, City Project No. 02- 03; and 2) Receive and file a progress report on construction change orders authorized by the City Manager pursuant to City Council Resolution 22009 adopted July 25, 2007; and 3) Authorize the City Manager to execute all necessary documents. STAFF ANALYSIS: On July 25, 2007, the City Council originally awarded a construction contract to McKenna General Engineering, Inc„ for the Gene Autry Trail Widening (Vista Chino to UPRR), City Project No, 02-03. The contract award amount was $4,383,933 and construction of this project started on August 20, 2007. ITEM NO. r , -:•� City Council Staff Report July 16, 2008 - Page 2 McKenna General Engineering, Inc. —Change Order No. 9 (CP 02-03) Concurrently, City Council approved a contract services agreement with WEC Corporation, to provide the City with turn-key construction inspection and administration of this project. Included with the City Council's approval of the WEC Corporation contract was an authorization to allow the City Manager to approve cumulative change orders up to 10% of the awarded construction contract amount, subject to reporting back to the City Council. On March 19, 2008, a report on the cumulative contract change orders (Change Orders No. 1 through No. 6) for a total cumulative cost of ($1,366.15) was provided to the City Council. Attachment 1 includes a report on the cumulative contract change orders approved to date for this project (Change Orders No. 1 through No. 8). The total cumulative cost of change orders approved by the City Manager to date is $429,085.31 -- or 9.8% of the original contract amount. A majority of the cost increase is related to the City's initiated changes to the planned widening at Vista Chino coordinated with Caltrans. The Public Works and Engineering Department coordinated the design of an additional southbound right-turn lane, and a second (dual) southbound left-turn lane at Vista Chino, to be consistent with ultimate lane configurations identified in the City's General Plan Update Traffic Impact Analysis. The intersection improvements required upgrading and modification of the existing traffic signal at Vista Chino and Gene Autry Trail, which was not originally included in the Bid. Another major factor of the cost increase is related to final asphalt pavement quantities required in the project; in order to establish the finish design grade of the roadway through the Whitewater River, additional pavement was required. A final component of the project was added, at the direction of the U.S. Fish and Wildlife Service in consultation with, and with the approval of, CVAG. The U.S. Fish and Wildlife Service required the installation of new sand fences for mitigation of impacts to the Coachella Valley fringe-toed lizard, which was installed by our contractor on BLM land near the southwest quadrant of the Gene Autry Trail / UPRR bridge. Construction Change Orders No. 1 through No. 8 increased the original contract total to $4,813,018.31. Construction Change Order No. 9 represents the first change order requiring the City Council's approval, and will increase the original contract total by $362,610.08 for a final total contract amount of $5,175,628.39. Staff recommends that the City Council approve Change Order No. 9, which will close-out this project. FISCAL IMPACT: All costs associated with this project are reimbursed up to 75% by Regional Measure A funding. Currently, Agreement No. 4393 with CVAG provides the City with $7,875,000 in Regional Measure A funding for the Gene Autry Trail projects. In accordance with Agreement No. 4393, sufficient funding is available in Regional Measure A account 134- 4497-50217. od©®� L City Council Staff Report July 16, 2008-Page 3 McKenna General Engineering, Inc. —Change Order No. 9 (CP 02-03) SUBMITTED: David J.
