As of 2:15pm, repairs on the water main line have been completed and water service is back on.

At approximately 9:00am while Synergy was working to remove asphalt at the corner of Fourth and Bryant streets to relocate underground utilities, a 2ft x 2ft piece of concrete slipped through the jaws of a backhoe and landed on top of a water main line causing a 1 foot wide hole in the pipe. As a result, the water on Fourth Street between Bryant and Brannan streets had to be shut off in order to repair the broken pipe.

Thanks to the SFPUC, SFPD, CHP, SFFD and DPW for assisting with the situation and controlling traffic flow.

The Central Subway Project received great news this week! The project has been awarded $27 million in tunnel component funds from the California Transportation Commission (CTC).  These funds are awarded for the Central Subway’s future connection to the California High Speed Rail that is currently in planning.  The route of the High Speed Rail is to begin in Los Angeles with its Northern Terminus to be in San Francisco at the Transbay Terminal that is slated to begin construction in August 2010.  The Central Subway connection to the High Speed Rail will be at the prospective Brannan Street Station located at Fourth Street and Brannan, along the Central Subway alignment.  These funds will help with construction costs for the tunnel portion of the project and will also decrease the amount needed from local funding sources.

The following in italics is cited from the Muni proposal to the CTC:

San Francisco Municipal Transportation Agency (Muni) is proposing to program:

• The tunnel component ($27 million) of its Central Subway light rail line that starts at the Caltrain (PCJPB) depot and goes north to Chinatown.  The Central Subway will be the first major north-south rail connection to the east-west BART/Muni subway at Market.

Muni is proposing to extend the connectivity of its system with the existing BART system, Caltrain system and the proposed high-speed system.  The connectivity should increase ridership and reduce travel times, similar to the benefits that would occur with the Los Angeles’ Regional Connector.  The tunnel component will permit Muni to begin the tunneling.

Commission staff recommends that the project be programmed.

Chairs and Commissioners, May 10, 2010

The Central Subway Project continues to press forward with growing support and progress. This awarding of funds is seen as a great accomplishment and is an affirmation of the Central Subway’s importance to the future of transit growth in the City of San Francisco.

*Correction: The transfer stations for the high-speed rail will be at the Fourth and King Stations. The Brannan Station will be the last surface station before the tunnel on the Central Subway phase.

Contrary to the Examiner article “Central Subway behind schedule,” dated 5/11/10 and written by Katie Worth, the Central Subway Project boring operation is not behind schedule.  The schedule for this segment, geotechnical drilling, of the project was rearranged to accommodate concurrent on-going utility relocation activities.  This is simply an example of contractors working together and modifying their schedules so that multiple jobs can take place at the same time without schedule delays.  This displays the professional coordination among contractors working on the project.  We expect to see more adjustments to facilitate parallel tasks throughout the project.  Furthermore, the geotechnical investigation phase has no bearing within the overall project schedule.

The San Francisco Municipal Transportation Agency and PB/Telamon with Treadwell & Rollo will continue drilling operations for supplemental geotechnical investigations; the purpose of which are to provide critical geotechnical and hydro-geologic information needed for final design and pre-construction of the proposed subway tunnel and associated structures.

Here’s the anticipated drilling schedule throughout the month of May:

• May 13-14, 2010: Drilling will be on Stockton and Clay in Chinatown during the day.
