AS4 Contractor Reaches Safety Milestone!

As of November 2010, the regional projects for the San Francisco Public Utilities Commission’s Water System Improvement Program (WSIP) achieved over 1 million safe working hours without major injuries since April 2009. The Alameda Siphon No. 4 project was one of the projects recognized as part of this achievement.

This significant milestone required a total commitment to safety by all participants including contractors, subcontractors, construction managers, consultants and SFPUC staff. The SFPUC salutes Steve P. Rados for active engagement, support and participation in the WSIP Safety Approach.

Recently, the project team presented representatives from Steve P. Rados with a certificate to recognize one million safe working hours.

Construction Notice: Irvington Portal

Construction at the Irvington Portal Work Area began today. The Irvington Portal Area is located immediately east of Mission Boulevard near Mission San Jose High School.

What to Expect

The following activities will take place through out the month of January:
Potholing: Potholing is the practice of verifying the location of existing pipe utility locations by physically digging into the ground and uncovering the pipe. A backhoe and trench box to excavate around the existing pipes will be required in approximately 6 locations. Trucks used to haul equipment on and off the site will also be used during this time.
Steel I-Beam Installation: Steel I-beam columns 10 foot to 20 foot tall will be placed into the ground. The columns are necessary for the future installation of sound barrier panels. The column installation involves a small truck mounted auger drilling holes in the ground into which the base of columns will be embedded with concrete.
Gravel Lay Out: Gravel will be laid out on the project site to prevent track out of mud and dirt by construction traffic onto Mission Boulevard. Gravel lay out will involve the spreading out of gravel rock over an area of ground for the temporary parking of equipment and materials.

By Spring 2011, 10 – 20 foot sound barriers will be installed at the project site. In some sections, the sound barrier will be transparent in the upper portion of the barrier to allow for sunlight. Once the sound barriers are in place activities including tunneling, excavation, hauling soils from the tunnel shaft, installation of construction offices and facilities will take place. The Irvington Portal will remain an active construction site until the end of project scheduled in mid-2014.

Construction Hours

Work will take place at this location 7AM to 7PM on weekdays and 8AM to 5PM on Saturdays. However, for two 3-month periods (beginning November 2011 and November 2012), work hours may be extended to 24 hours-a-day; 7 days-a-week.

Noise & Sound

The Irvington Portal will be an active construction site. The sound of construction equipment and vehicles in operation should be expected. However, the contractor must stay within strict noise limits at the work area at all times.


Delivery and movement of construction equipment and worker travel will be the primary source of traffic. Flaggers or other equivalent traffic control safety measures are required during morning school arrival (7:00 AM & 8:00 AM) and afternoon release (2:00 PM & 3:00 PM).
