Summer/Fall 2010 Update: New Crystal Springs Bypass Tunnel


Summer/Fall 2010 Update: Making Progress!
The San Francisco Public Utilities Commission (SFPUC) is making significant progress on the completion of the New Crystal Springs Bypass Tunnel & Pipeline near Polhemus Road in San Mateo. As of the end of July 2010, the project has reached 81% completion! We’re on schedule and making excellent progress. We expect full completion in Fall 2011.

Grouting and related underground work inside the tunnel will be completed this month and surface pipe work will take place into November.

Dust control measures are in place to reduce the amount of dust near our construction sites. Additional sprinklers are in use in the muck disposal area and near the stables.

In January 2011, important pipeline connection activities will require additional work hours at night for approximately 2 weeks. More information and details will be provided in advance.

San Mateo County will be closing Skyline Bridge in late September 2010. For more information, visit www.co.sanmateo.ca.us/portal/site/publicworks.

Liberty Mutual Group Honors New Crystal Springs Bypass Tunnel Team with Prestigious Safety Award


Liberty Mutual Group Honors New Crystal Springs Bypass Tunnel Team with Prestigious Safety Award

Insurance company representatives typically visit a construction site because of a personal injury, accident, claim or property loss.

When Bob Snyder and Joe Puente of Liberty Mutual Group visited the New Crystal Springs Bypass Tunnel construction site in San Mateo on Friday, August 20th, there was reason to celebrate.

Shank/Balfour Beatty (S/BB), the contractor for the New Crystal Springs Bypass Tunnel project, was presented with a Commendation Award by insurance company Liberty Mutual Group. The prestigious award recognizes S/BB’s achievement of working over 165,000 hours without a recordable injury since beginning the project in December 2008 through July 2010. This is a huge accomplishment and honor, especially considering the hazards associated with underground construction. S/BB sunk two construction shafts 156 feet and 56 feet deep, then excavated a 12 foot diameter tunnel approximately 4,200 feet long between shafts. Following tunnel completion, 96-inch diameter welded steel pipe was installed in the tunnel and shafts. The pipeline was tied into the Sunset Supply Pipeline in January 2010 and the final tie-in to the Crystal Springs Bypass Pipeline is scheduled for January 2011.

“It is my pleasure to present this Commendation Award to the New Crystal Springs Bypass Tunnel team for your excellent safety record,” said Bob Snyder, Loss Control Manager of Liberty Mutual Group. “This is only the third award I’ve given this year. Congratulations to the managers and workers who deserve recognition for such a great achievement. ”
“This award demonstrates the success of our Water System Improvement Program safety policy,” said Alan Johanson, San Francisco Public Utilities Commission Regional Construction Manager. “Everyone on this team deserves recognition for consistently following safety policies on the job site.”


“Safety is a top priority,” said S/BB Safety Manager David Tompkins. “It is quite an achievement to work this many hours on a complex construction project without any recordable injuries. I am extremely proud of this team.”

Project Construction Manager Victor Romero of Jacobs Associates commented that the project’s excellent safety performance is the result of realistic hazard recognition, effective planning and communication, and excellent teamwork among all personnel working on the project.

The project is approximately 80% complete and on track to reach substantial completion by fall 2011.

Golf Balls on Construction Site can be Dangerous

Dear Golf Lovers near South Shaft construction site,

The New Crystal Springs Bypass Tunnel project team has been finding a number of golf balls at the South Shaft construction site off of Polhemus Road in San Mateo. The project team believes the golf balls are coming from nearby homes above the construction site.

While we understand and share a love for golf, the project team would like to remind neighbors that golf balls can pose a significant danger to workers and construction equipment at the construction site.

Fast moving golf balls can strike workers, staff or cause significant damage to construction equipment such as cranes, cars and machinery, which can cause further injury to people.

We respectfully request that who ever is hitting these golf balls toward the construction site to stop immediately.

Thank you,
New Crystal Springs Bypass Tunnel project team

TONIGHT: Early Morning Delivery at South Shaft site at Polhemus Rd in San Mateo

Early Morning Delivery to South Shaft Site in San Mateo - TONIGHT
In the early morning of Tuesday, August 10th, at approximately 1 or 2 am, a large semi-truck and flatbed trailer will arrive at the South Shaft site off of Polhemus Road and park near the office trailers. A large, special pipe section is being delivered. Because of the size of the load, the truck must travel during nighttime hours only.

The truck will pull into the main gate, drive up the paved road to the office trailer parking lot, the truck will be shut down, and will remain parked there until 7:00 am or later at which time the truck will be unloaded when the workday begins.

Several California Highway Patrol cars will accompany this special permit truck load. The Highway Patrol will temporarily close Polhemus Road for a few minutes during the delivery and reopen it as soon as the truck is off the road. Because this will take place during early morning hours, traffic delays are not anticipated.

Every effort will be made to avoid noise during delivery so not to disrupt neighbors.
