New Crystal Springs Bypass Tunnel: Pipeline Connection Activities and 24-Hour Work

In January and February 2011, the SFPUC and its contractor will be performing water pipeline connection activities at the North Shaft (Crystal Springs Road at Polhemus Road) and the South Shaft (Polhemus Road between Bunker Hill and Crystal Springs Road)in San Mateo.

Several workers from the SFPUC’s Water Supply & Treatment Division will be performing 24-hour pipeline de-watering and treatment work at both the North and South Shaft sites starting on or around January 4th through the 9th. Downward-facing lights will be in use at night during this time.

Workers and staff will be at the North and South Shaft sites and along Polhemus Road at various times from January 3rd through the 17th to prepare for pipeline connection activities. Tunnel ventilation equipment, including an air compressor, will be in use at the South Shaft during the day on Sunday, January 16th.

Starting on or around January 17th, 2011, the contractor will perform critical work to connect the new pipeline to our water system. These important pipeline connection activities at the South Shaft site will require crews to work up to 24 hours a day, 7 days per week for approximately 3 weeks to complete this critical work as quickly as possible. Neighbors may experience some noise from the crane and equipment.

Additional environmental training focused on minimizing noise, especially at nighttime, is being conducted for all workers on site.

We do not anticipate any interruption to your water service. This important work is necessary to connect pipelines for your water supply.

Local Students Learn about Engineering and Teamwork at the New Crystal Springs Bypass Tunnel Project

After driving by the New Crystal Springs Bypass Tunnel site in San Mateo for several years, Dr. John Venuti, the Director of Information Technology at nearby Crystal Springs Uplands School, arranged a site visit for a group of his top senior students.

Strong in math and considering careers in engineering, the students met with project staff and learned about engineering and construction careers associated with the project.

Students learned about the importance of the Water System Improvement Program (WSIP) to rebuild and upgrade the Hetch Hetchy water system before the next major earthquake strikes the San Francisco Bay Area. They were excited to learn that the San Francisco Public Utilities Commission (SFPUC) is using social media such as Facebook, Twitter and YouTube to educate the public about the WSIP and many other projects.

Blake Rothfuss, assistant construction manager and consulting engineer with Jacobs Associates, told the students how the new tunnel was created using a tunnel boring machine. He explained the advantages of boring the tunnel and placing the pipeline deep underground, deeper than the original, near-surface pipeline to improve its performance during an earthquake. “Planning, commitment, advanced engineering and teamwork are needed to successfully complete unique tunnel projects like this one,” said Blake.

SFPUC civil engineer Holly Chan talked about the importance of teamwork and how working together moves the project forward successfully. After graduating from San Francisco State University with a master’s degree in civil engineering, Holly has been able to put her engineering skills to the test by working on this complex and often difficult tunnel project. “It can be hard sometimes, but we work together and figure out the best way through a problem,” said Holly.

“These students are setting their sights on careers in engineering,” said Dr. Venuti. “Talking with successful engineers working on a huge project like this is really a great benefit for them.”

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

SFPUC and Shank/Balfour Beatty Sponsor Pipeline Confined Space Rescue Training on Peninsula

This Spring, representatives from several Peninsula fire agencies participated in a rescue training exercise within a vault and pipeline being constructed by Shank/Balfour Beatty, the contractor on the New Crystal Springs Bypass Tunnel project in San Mateo.


The training exercise simulated a medical emergency in which a pipeline worker suffered a heart attack while painting a 60-inch diameter butterfly valve within the pipeline. None of the firefighters had ever been inside any of the San Francisco Public Utilities Commission's (SFPUC) pipelines or vaults.

Firefighters arrived on site, were briefed by the contractor’s liaison, and then performed a permit-required confined space entry. Medics provide initial treatment to the “victim” adjacent to the valve, then packaged and transitioned the victim through a 24-inch diameter manhole into the vault. Due to limited overhead clearance, the “victim” was again transitioned and hoisted through a hatch in the roof deck where he was treated by the medical team and prepared for air transport. The training exercise was completed in about 2 hours.


Carl Kustin, Lead Instructor for trainers Lea & Associates, said “The SFPUC and Shank/Balfour Beatty provided a once in a lifetime opportunity for firefighters to train in an environment where SFPUC employees and contractors work every day. We hope there’s NEVER a need for our services, but when that time comes, the firefighters in this class are much better prepared to quickly access an injured pipeline worker. This was an exceptional training day!”

Representatives from the following agencies participated in the training: San Mateo Fire Department, South San Francisco Fire Department, Burlingame Fire Department, Central (San Mateo) County Fire, Mountain View Fire Department, South (San Mateo) County Fire, Menlo Park Fire District, San Jose Fire Department, SF General Hospital, and the California Urban Search & Rescue Task Force 3 (Menlo Park).

SFPUC Labor Relations Efforts Paying Off During Economic Downturn

New Crystal Springs Bypass Tunnel contractor Shank/Balfour Beatty has 27% of its workforce hours in apprenticeship, exceeding the California Division of Apprenticeship Standards requirement of 20%, according to the WSIP Labor Relations Office. The contractor is also providing tunneling equipment on loan to the Northern California Laborers Apprenticeship Program for use in training programs, reports Ardis Graham, Project Labor Agreement Administrator.

The New Crystal Springs Bypass Tunnel is one of SFPUC’s water system improvement projects, and is covered under the WSIP’s Project Labor Agreement (PLA).

For crane and equipment apprentice Simon Streeter and welding apprentice Justin Stephens, the PLA’s initiatives have resulted in opportunities to learn new, transferable skills through the Tunnel project. “We’re learning from guys with many years of experience. They look out for us. It is great to be employed in a good paying job where I learn something new each day,” said Streeter. Both men are residents in the WSIP service area.

Pipeline Dewatering to Begin near Tartan Trail Road

In late January 2010, the SFPUC and its contractors are planning to drain a water pipeline located off of Tartan Trail Road in Hillsborough as part of the New Crystal Springs Bypass Tunnel project located on Polhemus Road. Please see map for detailed location of work.

The dewatering of the pipeline is necessary for the eventual completion of a new critical pipeline to carry water under Polhemus Road and to ensure delivery of drinking water after a major earthquake.

What Neighbors near Tartan Trail Road Can Expect:
SFPUC and contractor crews will mobilize equipment in late January and park trucks on the existing gravel parking area off of Tartan Trail Road on SFPUC Right of Way property (please see map on reverse for location).
Dewatering will take place 150’ north of Tartan Trail Road and will take place 7 days per week. Crews may be on site 7 days a week between 7am and 6pm.
Overhead tree limbs will be moved for construction access and allowed to return to original position. Minor limbs may be removed to prevent safety issues. The dewatering site will keep wildlife from harm by installing an exclusion fence adjacent to San Mateo Creek.
Approximately six people will be on site daily for the first week, with fewer on site during the remainder of the work.
Dewatering activities will include use of a crane, trucks, a WhisperWatt generator and pumps. Water will be safely discharged into San Mateo Creek following all environmental guidelines as specified by regulatory agencies.
The use of equipment for this project is not expected to exceed noise limits established by the Town of Hillsborough. Mitigations for noise such as acoustical blankets will be provided if needed to conform to noise limits.
Activities will take place at this site into April 2010. Upon completion, crews will remove all equipment.

Neighbors Tour South Shaft Site Following 4.1 Earthquake

Just minutes before the start of their New Crystal Springs Bypass Tunnel South Shaft tour on January 7th, San Mateo neighbors Howard McDonel, Helmut Schagerer, Erwin Hagele and Nick Lolonis heard about the 4.1 earthquake epicentered on the Calaveras Fault near Milpitas. Howard felt it, while the others did not. They toured the construction site and discussed engineering and construction methods being used to build the tunnel and pipeline.

The relatively small earthquake is a good reminder of the race against time the San Francisco Public Utilities Commission faces to seismically upgrade the aging Hetch Hetchy water system before the next big earthquake.

San Francisco Bay Area residents can get prepared for the next big earthquake by storing at least one gallon of water per person to last at least 3 days following an earthquake. Learn more at http://www.72hours.org/.
