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.
• May 17-20, 2010: Drilling will be on Stockton and O’Farrell (in front of Macy’s) during the day.
• May 26-27, 2010: Drilling will be on 4th Street and Folsom on Folsom during the day.
• May 24-25, 2010: Drilling will be on Stockton and Market (in front of Virgin) during the day.
• May 15-16, 2010: Drilling will be on Stockton and Washington (near the school yard) during the day.
