SFPUC- Chooses SEI Industrial Chemicals Graffiti Proofer for Tunnel

The New Irvington Tunnel project in Alameda County, California is part of the $4.6 billion Water System Improvement Program (WSIP) launched in 2002 to repair, replace, and seismically upgrade the aging San Francisco Regional Water System, often referred to as the Hetch Hetchy system. Owned and operated by the San Francisco Public Utilities Commission (SFPUC), the system delivers drinking water to 2.5 million people in the five counties of San Francisco, San Mateo, Santa Clara, Contra Costa, and Alameda.

Built between 1928 and 1930, the existing Irvington Tunnel is an important part of that water delivery system because it connects the water supplies from the Sierra Nevada Mountains and the Alameda Watershed to Bay Area water distribution systems serving SFPUC customers. Expected to be completed by early 2014, the new 3.5-mile tunnel will lie parallel to the existing tunnel between the Sunol Valley south of Highway I-680 in unincorporated Alameda County and the Mission San Jose district in Fremont. The Town of Sunol receives the majority of its water from the SFPUC and the City of Fremont receives approximately 30 percent of its drinking water from the system.

Constructing a tunnel parallel to the existing Irvington Tunnel, in Alameda County, Calif., allows the San Francisco Public Utilities Commission to decommission the Irvington Tunnel for inspection and rehabilitation to improve the water delivery reliability. The total construction cost for the project is estimated at $154 million.

The exterior walls leading to the location were stained and required to have superior anti-graffiti protection to help prevent, deter and protect the structure from the elements, paint, labels, markers, other graffiti and various chemicals.

The SEI Chemicals Graffiti Proofer was tested and selected for this project. The wall featured in the above picture is approximately 9,000 sq ft and is coated with SEI’s GPA-300 Graffiti Proofer non-sacrificial anti-graffiti coating. Graffiti removal can be performed without using any chemicals.

SEI Industrial Chemicals Anti-Graffiti coating on 24,000 sq ft concrete sound walls

24,450 sq ft of precast concrete sound walls

The City of Sparks, a neighboring city to Reno, NV, utilized SEI Chemical’s anti-graffiti coating technology to protect 24,450FT2 of precast concrete sound walls in September, 2012. The project consisted of (4) individual walls, which would all receive an oxidizing stain treatment before being protected with (1) coat of SEI Sealer Prime followed by (1) coat of GPA-300 Graffiti Proofer®.

Josh Thompson, Civil Engineer for Atkins Global, headed up the project design. The City of Sparks requested Mr. Thompson spec the Graffiti Proofer as the anti-graffiti coating of choice for this project. As a sole-source specification could not be permitted, Mr. Thompson included the following:

Anti-Graffiti Coating shall be Seicoat Graffiti Proofer GPA-300 per NDOT QPL requirements, or approved equal. Alternate submittals will not be considered without meeting the following minimum requirements:

• Graffiti removal by wiping with a dry cloth or with light pressure washing. No release or
cleaning agents required.
• Non-sacrificial, non-yellowing and clear
• Allows expansion and contraction
• Meets the performance requirements of ASTM D6578, Level 10
• Included on Nevada Department of Transportation’s current Qualified Products List

All alternate product submissions ultimately fell short of the requirements and were not approved. The application of the Graffiti Proofer to the Vista sound walls provides the City of Sparks with the largest surface area, in Nevada, which allows graffiti to be removed without using chemicals.

San Francisco Presidio Trust

The BSM-1600 Synthetic Membrane is unique in many ways, but to name a few, it is a single component (no mixing required), does not need a primer, low VOC (<50 g/L), water based, comes in 5 standard colors (plus custom color matches available) and can withstand vehicular traffic. This SEI Industrial coating bonds to asphalt, concrete, raw wood and other porous substrates and is highly resistant to abrasion, impact, moisture, chemicals and atmospheric salts. The anti-slip membrane has tremendous elongation and tensile strength and can be applied in only 1 coat. If it ever damaged simply recoat as the coating adheres to itself.
