Adopt Resolution increasing the Director of Transportation’s change order authority to a total of $425,025 for Department of Transportation Contract Number 170079 for construction of the Davis Creek Bridge Replacement on East Hill Road, County Road 301, Milepost 2.01 (Willits Area); and authorize Chair to sign same.

Previous Board/Board Committee Actions:
By Resolution No. 12-002 (January 10, 2012), the Board of Supervisors (BOS) approved BOS Agreement No. 12-005/DOT Agreement No. 110102 with Drake Haglan & Associates for plans, specifications, and estimate bid package for the Davis Creek Bridge on East Hill Road. By Resolution No. 13-099 (October 8, 2013), BOS authorized DOT Director to approve and execute amendments up to $55,000 to DOT Agreement No. 110102. By Resolution No. 13-124 (December 10, 2013), BOS approved execution of a Memorandum of Agreement with the City of Willits concerning the waterline relocation work for the Davis Creek Bridge Replacement project. By Resolution No. 14-151 (December 2, 2014), the Board approved Amendment No. 5 for a supplemental Extended Phase 1 Study for a previously unrecorded archaeological resource discovered at the site. By Resolution No. 17-186 (December 5, 2017), the Board authorized the Director of Transportation to advertise for bids and award DOT Contract No. 170079 for construction of the Davis Creek Bridge Replacement project.
Summary of Request:
On May 7, 2018, Mendocino County awarded DOT Contract No. 170079 to Viking Construction Company, Inc., of Rancho Cordova, California, in the amount of $4,250,255. By Resolution No. 07-008, the Director’s original contract change order authority amount for DOT Contract No. 170079 was $225,012. Over the course of construction unforeseen conditions, such as, bats living in the old bridge, unsuitable subgrade material, buried debris, and excessive groundwater have depleted the Director’s original contract change order authority amount of $225,012. The original plans did not include a pedestrian railing above the vehicle rail of the bridge. Addition of this railing will cost an estimated $85,900 and is considered essential for proper safety. In order to keep the project moving, DOT is requesting an increase of the Director’s change order limits to a total of $425,025 to match the 10% contingency of $425,025 for contract changes that was initially budgeted and approved by FHWA, in order to cover the costs of the pedestrian railing as well as any other unforeseen changes that may arise during construction. Costs of the project are to be funded primarily through the FHWA Highway Bridge Program (HBP), with the local match covered by the Toll Credit Program.
Alternative Action/Motion:
Do not approve increasing change order authority and let the items go to claims.
