March Construction Update

ACWD pipeline replacement work is underway near the homes on Curtner Road off of Mission Blvd. in Warm Springs. This pipeline replacement work is to ensure that homes in the area have a reliable water supply following an earthquake.

To conduct this pipeline replacement work, the contractor requires a two-week road closure of Curtner Road between Mission Blvd and Briar Place beginning this week until mid-March. Over the next two weeks, construction crews will be installing a brand new ACWD water delivery pipeline that will connect to the newly installed SFPUC BDPL3&4 pipelines.

Residents in the area should take Paseo Padre Parkway for entry to and exit from the neighborhood during work hours.

City of Fremont Approved Work Hours / Road Closure Hours:

•  Monday to Friday: 7 a.m. to 5 p.m.
• Some Saturday work is permitted and may be required
• 24/7 Road Closure of Curtner Road may be required for the safety of pedestrians and motorists.

Restoration Work Continues:

While construction continues on the ACWD water delivery pipelines, restoration work continues on the SFPUC Right-Of-Way where the new BDPL3&4 pipelines were installed last year.

Final completion of this project is anticipated for May 2015.

Overnight Work & Lane Closure for Eastbound Mission Boulevard Traffic Near I-680

 

On Thursday, Feb. 12 from midnight to 5 a.m., construction crews will work along eastbound Mission Blvd. near I-680. A full road closure for eastbound traffic is required during these work hours to install brand new water delivery pipelines to homes in the Fremont area. Why? While the new, seismically upgraded BDPL 3&4 pipelines have been installed, one of the final parts of the project is the installation of two smaller water lines--one 30 inches in diameter and one 12 inches in diameter. This pair of Alameda County Water District water delivery lines runs under the median of Mission Blvd. and turns onto Cutner for connection to the existing distribution system. The contractor needs to close the road to eastbound traffic in order to conduct this work.   On Thursday, Feb. 19, from midnight to 5 a.m. (Wednesday to Thursday morning),  a full road closure to eastbound traffic along Mission Blvd. is needed to install two water delivery pipelines.

WSIP Recognizes Construction Project Teams for 7 Million Safe Work Hours

The construction teams working on Water System Improvement Program (WSIP) projects recently achieved a huge and important milestone. Between April 2009 and October 2014, these project teams performed 7 million hours of work on major construction projects, without a single major injury or incident. SFPUC representatives acknowledged this with a formal presentation of a certificate to the active construction management and contractor teams in December.

The WSIP projects have significantly lower rates of recordable injuries and lost work time compared to the national industry averages. The safety successes are a result of a robust safety program that has been embraced by the construction management teams as well as the project contractors. This milestone is evidence of the project teams’ outstanding commitment to the Think Safety, Work Safely approach, ensuring the program’s construction sites are safe places to work.

Fence Installation Work Pending

In order to continue our seismic upgrade work, SFPUC construction will be occurring behind the Villa Caprice Apartment buildings on Crawford St along the SFPUC Right-Of-Way. After discussions with the Villa Caprice property management, our contractor will begin installing a new security fence in mid- to late-December, to better protect and safeguard our property.

To do this work, the existing fence that currently separates the Villa Caprice Apartment buildings from SFPUC property will need to be completely removed. The contractor anticipates that the removal of the existing fence and the construction of the new fence will take approximately four weeks.

Permitted Work Hours:

Monday to Friday:  7 a.m. to 5 p.m.

Saturdays:               9 a.m. to 6 p.m.

NEXT STEPS

The SFPUC will distribute an additional work notice with specific times and more details as soon as work December dates are finalized.

The contractor may also require that car owners park their vehicle slightly behind a marked line for ease of work and safety of vehicles

Overnight work and Lane Closure Scheduled at Mission Boulevard and I-680

On Friday, August 22 beginning at midnight to 5 a.m. construction crews will be working overnight to shift the I-680 northbound on-ramp at the eastbound lanes of Mission Boulevard back to its original position. During these work hours, the northbound on-ramp and right-hand eastbound lane at Mission Boulevard and I-680 will be closed. When work is complete, traffic will be rerouted to the permanent on-ramp.

Why:   Workers are replacing and retrofitting large pipelines under the current I-680 northbound on-ramp to ensure the region has a reliable water supply following an earthquake. The construction work taking place at the original on-ramp is now complete, allowing the northbound on-ramp to be restored to its original position.

When: Friday, August 22, Midnight to 5 a.m. (Thursday night to Friday morning)
         
Where: Mission Boulevard at I-680 in Fremont

Ramp Closure Detour: Trucks will be rerouted north on Mission Boulevard to Durham Road and I-680. All other traffic heading east on Mission Boulevard will be directed to make a u-turn at Paseo Parkway. Once heading west, drivers can use the northbound on-ramp on the west side of Mission Boulevard.

The northbound on-ramp at Mission Boulevard and I-680 will be shifted back to its original position.

Wishing You a Happy Fourth of July

On behalf of the San Francisco Public Utilities Commission and the Bay Division Pipelines Nos. 3 & 4 (BDPL3&4) project team and construction crew, we want to wish you a Happy Fourth of July. Construction work will not take place over the holiday weekend.

As we celebrate our country's independence, our team is also celebrating another success. This week, the BDPL3&4 project garnered the top story in Engineering News-Record. The magazine highlights the cutting-edge slip joint installation to help the pipe compress, move, and even rotate without rupturing during a major earthquake. The goal is to ensure that the 2.6 million people relying on the Hetch Hetchy Regional Water System, which includes BDPL3&4, can receive potable drinking water within 24 hours of a major earthquake.

The WSIP Turns 10!

This year the Water System Improvement Program (WSIP) turns 10! One of the largest infrastructure projects in the nation, the WSIP is repairing, replacing and upgrading our aging water infrastructure to ensure we can deliver water to customers following an earthquake. We’ve gotten a little nostalgic about how far we’ve come in the last 10 years, and we would like to share this video with you.



Now 80 percent complete, the WSIP has already provided increased reliability to the water supply for customers as a result of the completion of some of the program’s major projects. The program has created over 6 million construction craft hours to date, employing more than 11,000 workers since 2007. Nearly half of those workers live in our four-county service area.
