PPSU Construction Updates: South San Francisco & Colma Sites


Crews installing new pipeline at the Millbrae site in early November.


South San Francisco

The Peninsula Pipeline Seismic Upgrade (PPSU) project contractor, Ranger Pipelines, Inc., continues construction on both sides of Westborough Boulevard inside the San Francisco Public Utilities Commission’s (SFPUC)’s right-of-way in South San Francisco. Permitted construction hours in South San Francisco are Monday through Friday from 8 a.m. to 8 p.m. and Saturday from 9 a.m. to 6 p.m. After the underground tunnel is constructed under Westborough Boulevard, the contractor will install the new pipeline in January 2015. This tunnel design was selected to not obstruct traffic along Westborough Avenue.

Colma


The contractor started construction activities along the SFPUC’s right-of-way in Colma on Monday, November 17. This work includes removing debris within the right-of-way, setting up the construction staging areas, and installing construction fences along the SFPUC right-of-way to indicate the limits of construction. Construction hours are currently Monday through Friday from 7 a.m. to 5 p.m. The contractor will begin removing and replacing approximately 700 feet of aged pipeline in January 2015.

The PPSU project includes the seismic upgrades of three Hetch Hetchy regional water delivery pipelines located in Northern San Mateo County. This project will ensure the pipelines can continue to deliver water to customers after an emergency.
