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.

On Wednesday, November 5, the project contractor, Ranger Pipelines, Inc., will begin removing and replacing approximately 900 feet of an aging water pipeline between 1100 and 1094 Ridgewood Drive in Millbrae. The contractor will start this work by digging trenches, removing the old pipe and replacing it, and then welding the new pipe segments together before closing up the trench.

Permitted construction hours are currently Monday through Friday from 7:30 a.m. to 7 p.m. Construction activities at this location are expected to last through November 30, 2014. Please keep an eye out for intermittent lane closures and traffic changes on Ridgewood Drive.

What to Expect?
The contractor will work to minimize noise, dust and traffic impacts, but some disruptions are expected due to the nature of construction. Every effort will be made to keep these impacts to a minimum.
The contractor has implemented noise and vibration monitoring activities for this work including installing sound walls to help minimize noise. Dust control measures also include spraying water on the site and using tree chippings in the staging area to keep the dirt from stirring up into the air.

Night Work Continues at the Harry Tracy Water Treatment Plant

A swing shift crew will start this Monday night re-paving a section of road within the plant, 4 p.m. to midnight (Monday through Friday).

Work will begin on our roadway next to Highway 280, furthest from residential areas. Noise monitors will be present to ensure decibel levels are within the allowed range. The project team has received permission from Cal-OSHA to muffle backup alarms on construction vehicles to the immediate work area.

Neighbors on Crystal Springs Road may notice trucks delivering asphalt and removing soil from the plant. After 7 p.m., truck traffic will be limited to 2 per hour. All trucks will be escorted by pilot cars.

Regular water treatment operations at the plant are currently shut down to allow for construction. The plant is scheduled to resume water treatment in mid-December. Major construction at Harry Tracy is on schedule and on track to finish by the end of 2014.

Your feedback will help us with noise mitigation. Please do not hesitate to call, 24-hours a day at (866) 973-1476.

Millbrae Neighbors Tour Construction at the PPSU Project Site

Millbrae neighbors living near the Peninsula Pipeline Seismic Upgrade project toured the construction site last week. This site tour helped create a visual depiction of construction activities behind neighbors’ homes, to show how the contractor is working to minimize impacts and to give neighbors an opportunity to ask the project team questions about construction. 


This tour occurred two days before Ranger Pipelines, Inc. started removing and replacing 900 feet of vulnerable pipe near Ridgewood Drive and Banbury Lane. Permitted construction hours are Monday through Friday from 7:30 a.m. to 7 p.m. These construction activities are expected to last through November 2014. Please keep an eye out for intermittent lane closures and traffic changes on Ridgewood Drive.

Night Work at Harry Tracy

From mid-October through mid-December, regular water treatment operations at the plant will be shut down to allow for construction activities. Swing shifts or 24-hour work are expected. This is the final full plant shut down for this project. The project is on track and on schedule to complete major construction by the end of 2014.

Night lighting will be positioned to reduce visible impact to surrounding residential areas. Noise and vibration monitoring will be performed each night. The project team will make every effort to schedule heavy construction activities and deliveries during normal work hours.

Millbrae:
For this final shut down period, swing shifts may be required in work areas closer to our Millbrae neighbors on the following streets: Sycamore Drive, Crestview Drive, Larkspur Drive, and Pinehurst Court. All construction will take place within the plant property. Occasional truck traffic for concrete pours will continue on Helen Drive.

San Bruno:
Frequent truck traffic on Crystal Springs Road in San Bruno will continue through December. Trucks are escorted by pilot cars to warn motorists and ensure the speed limit is observed.

 Thank you for your patience during this critical water infrastructure project. The work is part of the ongoing seismic improvements, process upgrades and capacity expansion at the Harry Tracy Water Treatment Plant. Please subscribe to this blog (see right) for updates to the work schedule.
