Milestone: Non-stick Pipes Slipped Beneath I-680

On December 27, we placed the final length of the Bay Division No. 4 water pipeline under I-680 in Fremont. Representatives from the SFPUC, the general contractor and engineering firm came together this week to sign the final 25-foot-long length of pipe.

From L to R: SFPUC Project Manager Bryan Dessaure, Tony Ferencik and
Jim Pelletier of Steve P. Rados, Inc., WSIP Deputy Director of Construction
Alan Johanson and URS Corp. Structural Engineer Changmo Kwon.

In order to slide this new seismically-reinforced pipe into the existing pipeline, URS Corp. proposed an unusual method. Smooth sheets of the material used on non-stick pans, PTFE, were affixed to the inside of the existing pipe and the bottom of the new pipe. These sheets allowed the pipe to be slipped into place without using rollers or damaging the pipe coating. The material will also allow the new pipe to move more freely within the existing pipe during an earthquake so that it won't break.

WSIP Deputy Director of Construction Alan Johanson signs
his name on the final piece of Bay Division Pipeline No. 4
to be sliplined using the new technique.

We will continue installing additional segments of Bay Division Pipeline No. 4 pipeline throughout 2014 using a combination of open trenches and trenchless techniques.

White sheets of PTFE are applied to a pipe segment
 at the Seismic Upgrade of BDPL3&4.

Starting Wednesday, November 13, construction activities will take place during regular work hours, 7 a.m. until 7 p.m.

Workers will be replacing the Bay Division Pipeline No. 4, which runs parallel to the Bay Division Pipeline No. 3 that was upgraded in the Right of Way in August and September. The work will take place in SFPUC’s right of way parallel to Tissiack Place, between Mission Blvd. and Nugget Way.

This second pipeline will enhance the reliability of our water system in the event of an earthquake or other emergency. Installing the pipe will not require construction outside of regular work hours and will not require the closure of Nugget Way.

If you have questions or concerns, please call our 24-hour answering service at 866-973-1476.

Work will take place in the blue area.

A Bison Beneath Mission Boulevard

Vertebra bone found at the
construction site.

Paleontologists discovered fossilized bones of multiple species during construction this summer.  In addition to many microfossils (e.g. birds, fish, clams, and reptiles) several large mammal bones were found, possibly of an extinct type of bison believed to have lived during the Rancholabrean age sometime between 10,000 and 300,000 years ago.  Buffalo, the largest land animals in North America today, are a form of bison.  Because vertebrate remains are very rare these ice age fossils are considered a significant discovery and protected by both state and federal laws and regulations.

Paleontologists have been working at the site alongside construction crews in order to thoroughly evaluate and protect the fossil finds while causing minimal impact on the construction schedule. The team does not expect the discoveries to affect the construction project’s target completion date in late 2014.

Emergency Preparedness Month

The First 72 Hours
This October, take time to engage in your community, discuss ideas and plans, and prepare for an emergency or natural disaster. The SFPUC’s Emergency Preparedness Month encourages all San Francisco-area residents to become more aware and prepared for the next emergency, which is almost certain to take place in our lifetimes. The first 72 hours after an emergency are often the times when community members come together to help each other out. If we prepare beforehand, we’ll be better off when an emergency occurs.

What can you do?
Meet with your family, neighbors and community organizers to get connected, develop a plan and share resources. Use SF72.org and sfwater.org/BePrepared as starting points. You’ll find tips, guidelines for supplies, a mobile app and   stories from real San Franciscans.

This is our city
SF72.org was developed by San Francisco for San Francisco. Let’s protect each other and our city by using our resources and knowledge to the fullest when an emergency strikes.

Our community members are not the only ones getting prepared. The SFPUC has been improving and renovating our regional water system to ensure a safe and reliable water supply. Although San Francisco will always need to rely on this imported water from the Sierras, we are also developing additional water supplies that can be used in the event that our regional system is disrupted. For example, we are developing local wells in San Francisco to blend high-quality groundwater with our imported water supplies, and we’re producing recycled water for non-drinking purposes to reduce the amount of drinking water currently used in these ways.

Check www.sf72.org or www.sfwater.org/BePrepared for more information. 

 

Nugget Way Re-Opened to Traffic

Today our crews paved and re-opened Nugget Way for traffic. The street was closed in order to install a length of water pipeline.

 A second pipeline will also be installed in upcoming months, but will only extend from Mission Boulevard to Nugget Way and will not require additional street closures.

After the completion of all construction activities, Nugget Way will be paved again to improve appearance and durability.

Above: A backhoe excavated near 
Nugget Way last week. The pipeline

Construction Update: Mission Blvd. Lane Shift

A lane shift on Mission Blvd. east of I-680 in Fremont will take place after rush hour on Friday, July 26

In order to prepare for water pipeline installation work under Mission Blvd, workers will be shifting all four lanes of Mission Blvd. near I-680.

East- and westbound traffic will be shifted slightly to the north so that workers can drill piles and excavate a trench. Within this trench, workers will then be able to install a water pipeline within a protective concrete box while Mission Blvd. traffic continues uninterrupted.

The lane shift activity will take place without closures during a low-traffic period on Friday in the late morning or early afternoon.

Learning by Doing at the Bay Division Pipeline Nos. 3 & 4

From R to L: URS Intern Kelli McCurdy and SFPUC Intern Marisa Williams 

talk to Elizabeth Gruenstein and Vir McCoy, Specialty Environmental Monitors,

about the challenges of working near Agua Fria Creek.The interns are seen 

touring Agua Fria creek near Crawford Street, on the opposite side of I-680 

from the project’s current construction.

For the BDPL3&4 project team, summer not only brings hot Fremont days, but also the opportunity for summer internships. Over the last month, the SFPUC and the project’s design engineering firm, URS Corp., have both hired interns who will experience the real-life engineering challenges associated with rebuilding infrastructure in a state that is known for its earthquakes.

Not only are the students working together with engineers and the contractor to seismically upgrade a pipeline, but they are learning about the challenges associated with the busy I-680 commuter interchange and environmental mitigation efforts at a nearby creek. 

SFPUC Engineering Management Bureau Student Design Trainee Marisa Williams is excited for the hands-on nature of the internship. 

“My favorite part has been to see all the drawings and then to be able get out and see the actual site,” says Williams, a Civil Engineering student going into her fourth year at San Jose State University.

Next Stop: Warm Springs

On Wednesday, June 26, the SFPUC partnered with BART and Santa Clara Valley Transportation Authority (VTA) to show Fremont city councilmembers and local media three infrastructure improvement projects in Fremont's Warm Springs business district.

These construction projects are located within a 1-mile radius and are sandwiched between the I-680 and I-880 on Mission Blvd. They are part of regional water and transportation programs with a combined budget nearing $8 billion!

WSIP Director Julie Labonte welcomed the Fremont city council and reporters and 

announced that the WSIP and its 80+ projects are nearly 75% complete.

The event was designed to attract not only city council, but also reporters from multi-lingual and ethnic news sources. The event helped to reach commuters and residents of all cultural backgrounds throughout this diverse community. This summer kicked off major construction activities for all three projects that could cause delays for commuters who live in the area.

Fremont City Council committed nearly three hours out of their work days and participated in the event to understand the complexity of the construction projects and the lifelong benefits it would bring to their region.

"When agencies work together, the public wins," said WSIP Director Julie Labonte. "By coordinating our infrastructure improvements to enhance the economic vitality of the area now, we will minimize disruptions to Bay Area residents and visitors in the long run."

Radio, TV and print reporters participated in the tour to learn more 

about the infrastructure investments in the Warm Springs area. 

According to the South Fremont/Warm Springs Redevelopment Plan, within 25 years the Warm Springs business district is expected to grow employment by 48%. Due to excellent planning, this economic growth will be supported by the BART extension program, nearby VTA road improvements to Mission Blvd/Warren Ave and the seismic improvements to the Hetch Hetchy Water System that the SFPUC is undertaking within the Hayward Earthquake Fault at the I-680/Mission Blvd interchange.

Seismic Upgrade of BDPL 3&4 Project Manager Bryan Dessaure explained 

how the new pipeline design would ensure Fremont and our 2.6 million 

customers would have a reliable water supply following an earthquake. 

Construction Update: Ongoing Night Work at I-680 for Sliplining of Water Pipeline

Starting the week of June 17, the contractor will begin periodic overnight quality assurance monitoring work at the interchange of Mission Blvd. and I-680. This monitoring work is quiet and non-disruptive, and will only take place along Mission Blvd. in the I-680 interchange. At this time, this work will not be near homes and will not disrupt traffic. Approximately three to five crew members will be accessing this work area in the SFPUC right of way around the I-680 and Mission Blvd. interchange.

Since the project is located above the Hayward Earthquake Fault, it is important for the contractor to ensure the jobsite and the newly installed pipeline meets safety and quality requirements before the start of the following work day. The newly installed pipeline will be replaced using the "sliplining" method.

What is sliplining?
Sliplining allows a new pipe segment to be threaded into pre-existing tunnels and pipelines located below I-680 and the I-680 on-ramp. This will ensure traffic continues to flow on I-680 and the ramps. This work and monitoring will continue until the Spring of 2014.

Construction Update: Mission Blvd. Lane Shift

A lane shift on Mission Blvd. east of I-680 in Fremont will take place after rush hour on Thursday, June 6

In order to prepare for water pipeline installation work under Mission Blvd, workers will be shifting all four lanes of Mission Blvd. near I-680 this Thursday.

East- and westbound traffic will be shifted slightly to the north so that workers can drill piles and lay a bridge. Beneath this bridge, workers will then be able to install a water pipeline within a protective concrete box while traffic of Mission Blvd. continues uninterrupted.

The lane shift activity will take place without closures during a low-traffic period on Thursday in the late morning or early afternoon.

Recap: Joint Community Meeting with SFPUC, VTA & BART

Last week, Warm Springs residents had a chance to learn and ask questions when the SPFUC co-presented at a joint community meeting with VTA and BART. More than 50 residents attended to hear about three innovative infrastructure improvement projects near Mission Blvd., and many took interest in the details of the Seismic Upgrade BDPL3&4 project.

If you missed the meeting, below are some of the questions which were asked:

1. What are the project benefits?
   The purpose of the Seismic Upgrade BDPL3&4 project is to ensure that our 2.6 million Bay Area customers will have a reliable water supply following an earthquake. Since this project is located on top of the Hayward Earthquake Fault, the repair, replacement and seismic upgrades taking place are designed to provide a reliable and high-quality water supply that will ensure water for drinking and firefighting during an emergency.
   
   
2. How old is this pipeline and the Hetch Hetchy Water System?
   Much of the Hetch Hetchy Water System was built in the early 20th century, and critical components have reached the end of their useful life and are vulnerable to earthquakes. The BDPL3&4 pipelines are crucial to servicing our East Bay customers, and are a critical connection to the major pipelines that will carry water to the Peninsula.
   
   
3. Will the Seismic Upgrade BDPL3&4 Project require any disruptions of water service in Fremont?
   No. The project is designed to replace lengths of pipe while still delivering water to the region through other pipes in the Hetch Hetchy Regional Water System.
   
   
4. What is the lifespan of this pipeline, and what sort of earthquake is the pipeline designed to survive?
   Our pipes are designed with a lifespan of 50 years.  The new Bay Division Pipeline No. 3, referred to as “3x,” is engineered to withstand a fault movement of up to 6.5 feet, which will protect it against major earthquakes the likes of which have affected the Hayward Fault in recorded history.
   
   
5. What are shutoff stations, and why are they important to the project? 
   Two shutoff stations were installed in 2007 on either end of the pipeline upgrade project. These stations allow the SFPUC to control the flow of water between the pipelines and shut off water leakage should a pipe break occur at the Hayward Earthquake Fault.

 

You're Invited: South Fremont Construction and Community Public Meeting

South Fremont Construction and Community Public Meeting

Thursday, May 23, 2013

6:00 p.m. to 8:00 p.m.

South Bay Community Church, Multi-Purpose Room

47385 Warm Springs Boulevard, Fremont

The water pipeline project at Mission Blvd. and I-680 is one of three major construction projects laying the foundations for Fremont's new "Innovation District."

We encourage residents and business owners to join the City of Fremont, VTA, BART, CalTrans and SFPUC on Thursday evening to learn about the lifelong benefits and short term inconveniences that are associated with our projects.

Traffic-related detours and temporary lane/road/on-ramp closures will affect the widely used I-680, I-880 and Mission Blvd. commuter arteries over the next year. At the meeting you can learn more and ask questions about all three projects.

1. The Seismic Upgrade of Bay Division Pipeline Nos. 3&4 at Hayward Fault 
   The major upgrade of two regional water delivery pipelines that cross the Hayward Fault involves ongoing work activities through the end of 2014.
2. VTA Mission/Warren Area Improvements Project
   A 12-month Warren Avenue road closure between Kato Road and Mission Falls Court is scheduled to begin Monday, June 17, 2013. The closure will allow construction crews to trench Warren Avenue under the future BART system and build bridges for both BART and the Union Pacific Railroad.
3. BART Warm Springs Extension Project
   Work will include lane closures on South Grimmer Boulevard between Warm Springs Boulevard and Lopes Court to accommodate BART track way overpass.

Construction Update: Pile-driving Work Underway in Preparation for Water Pipeline Installation

If you use Mission Blvd. in Warm Springs or drive by our work area on the I-680, you might have noticed the arrival of some new, tall machines. These machines aren't bulldozers or excavators. Instead they’re being used to help drill holes for cement pillars in the earth – called secant piles – along the pathway of the new BDPL3 water pipeline.

The purpose of this secant pile work is to ensure that our regional water delivery pipelines are protected during an earthquake in the following ways:

1. The secant piles will serve as the pipeline’s first line of defense against earthquakes. Their existence around the newly installed BDPL3 pipeline will lessen the impact of soil movement on the pipeline’s own seismically-designed casing and joints. 
2. Secondly, these piles are necessary to serve as foundations for the temporary raised bridges which will soon replace the I-680 on-ramps and allow construction workers to access pipelines underneath Mission Blvd.
3. Finally, the piles act as barriers to shore up soil on either side of the project area, ensuring workplace safety during the project’s next phases.

To see more images by SFPUC photographer Robin Scheswohl of the secant pile drilling, watch our video below:

Upcoming Saturday Work Planned Around Mission Blvd. in Fremont

On Saturdays March 30, April 6 and April 13, positioning of guide beams will take place between 9 a.m. and 7 p.m.

Workers using a crane will move a guide beam to install a temporary on-ramp bridge. When completely installed, this bridge will ensure uninterrupted access to the I-680.

We ask that you reduce speed while driving past the active construction site on Mission Blvd. and obey our safety signs while walking around the work areas. The northern sidewalk along Mission Blvd. is closed, and heavy machinery and excavated pits make it dangerous for joggers and pedestrians. Pedestrians should cross and use the south side of Mission Blvd.

Work will take place on the highlighted length of Mission Blvd., 

and parallel to the highlighted on-ramp.

The contractor will employ best management practices to control noise, dust and other disturbances around the site.

If you have questions or concerns, please call our 24-hour answering service at 866-973-1476.
