Extended Work Hours at the Irvington Portal

New Irvington Tunnel Project
Extended Work Hours (24 hours-a-day 7 days-a-week)
November 5, 2012 through January 11, 2013

Project Update
Construction on the New Irvington Tunnel Project is more than half way complete! The tunnel will provide a seismically designed connection between our Alameda Watershed and Sierra Nevada water systems and our Bay Area customers. Winter time is upon us, which means it is shutdown time again.

Crews must construct upgrades to this water system while it still serves water to our customers. We need to shut down the pipelines in order to cut into them and weld pipeline connections. We can only do this for short periods of time during winter months when demand is low and we can still meet customer demand. We succeeded in completing a great deal of pipeline work during last winter’s shutdown, and look forward to making progress on this year’s planned shutdown as well. Because the timeline is short, we authorize our contractor to work 24 hours a day to complete the work.

What This Means
Beginning on November 5, 2012 through January 11, 2013, the contractor is authorized to conduct construction activities 24-hours per day 7-days per week at the Irvington Portal in Fremont.

What Can I Expect? 
On weekdays from 7AM to 7PM and weekends from 8AM to 5PM construction activities will be no different from what is currently being experienced. Outside of those hours the contractor can only work on connecting the new tunnel to the Bay Division Pipelines. This work may include welding and surface excavation. The operation of construction equipment (loaders, excavators and cranes) is necessary to complete this work. Worker trips to and from the site at shift changes will also take place.

Will Work Take Place During the Holidays? 
The contractor does not currently plan to work on Thanksgiving, Christmas or New Years Day. However, they have the ability to work on those days in order to complete their work within the extended work hour period. Residents will receive advanced notice if it becomes necessary to work on those days.
