Alameda County Transportation Commission project grant funding of Measure B

The project provided for the widening of Dougherty Road from four lanes to six lanes
between Sierra Lane and the Northern City limits. The work include d the installation of
new class II bike lanes; 1.4 miles of bicycle/pedestrian pathway; landscaped median
islands; storm drainage improvements; new curb, gutter, sidewalk, bus stops,
bioretention areas, and landscaping along the easterly side of the existing roadway.
The project also provided a rubberized asphalt overlay and new pavement markings
over the entire width of the roadway from Dublin Blvd. to the northern city limits, new
curb ramps, and fiber optic connections and traffic video cameras at signalized
intersections
To date, 38 contract change orders were issued totaling $2,165,368.99 for the project
varying from time extensions for adverse weather, the extension of bid item quantities,
to unforeseen conditions encountered while excavating, and installing unanticipated
utilities for the project. The final contract change order for $327,924.49 represents the
funding necessary to complete project construction and closeout the contract.
The contractor has substantially completed the project and is currently working to
correct deficient items identified through the punch list process and to complete project
closeout documentation. At this point, it is anticipated the project construction will be
fully completed, including the plant establishment period, by the end of the year.
The project experienced some significant impacts resulting from adverse weather,
unforeseen conditions related to utilities, and varying site conditions. Even with these
impacts the project construction will be completed for a total cost that is approximately
$400,000 below the Engineer’s estimated cost when the construction was advertised for
bids.
Once project construction is completed, Staff will recommend the City Manager to
accept the project and authorize the filing of the Notice of Completion, which begins the
warranty period. Additionally, after construction is completed, the City will be able to
closeout several regulatory permits which were necessary to construct the Project. Part
of that closeout process will include the final purchase of a conservation easement
(mitigation lands) from Collier Creek Mitigation Land. The conservation easement
purchase was a requirement of the regulatory agency permits and the purchase was
approved by the City Council in October 2015. The final step in the project will be to
submit Measure B & Measure BB grant closeout documentation to the Alameda County
Transportation Commission.
STRATEGIC PLAN INITIATIVE:
None.
NOTICING REQUIREMENTS/PUBLIC OUTREACH:
