In California, the Tuolumne County Transportation Council will be required to pay for $540,000 unanticipated contractor costs for work completed on the second phase of the East Sonora Bypass project. After decades of planning, funding for the second phase was secured through the proposition 1B-created Corridor Mobility Improvement Account and a 2006 voter-approved transportation bond measure. The project contracted to Teichert/MCM Construction.
The $53.4 million bypass, which opened to drivers in late 2013, extended the Highway 108 thoroughfare from where the first phase ended to Via Este. Construction was completed a year ahead of schedule and provided about $1.2 million in savings.
regulators alleged that inadequate erosion controls at a bridge abutment resulted in more than 800,000 gallons of sediment-laden stormwater being discharged into a nearby tributary of Curtis Creek during a series of storms between October and December 2012.
Additionally, Teichert/MCM Construction submitted a claim to Caltrans for $5.1 million in unforeseen costs related to stormwater mitigation. It went to arbitration.
The two sides later reached a settlement in which the contractor agreed to pay $700,000 of the fine and receive about $1.7 million for the additional work.
In late 2014, Caltrans reached a $2.7 million settlement with the Central Valley regional Water Quality Control Board over alleged stormwater violations during construction on the bypass.
Funding for the third phase has yet to be secured.
