Construction

San Bruno Grade Separation Project

Pile driving, which is an essential step in the construction of the foundation of the grade separation, began in February. Pre-drilling holes in preparation for the resumption of pile driving will continue this week. The drilling will be limited to weekday daytime hours from 9 a.m. to 3 p.m. The work will involve excavation and drilling into the ground.

Other work, which includes digging with a backhoe and mini-excavator, will be done from 7 a.m. to

4 p.m. Crews will excavate, install temporary shoring, install culverts, install utility infrastructure, prepare foundations, install rebar and pour concrete. Crews will use medium and heavy duty diesel vehicles to transport dirt and concrete.

Night work will occur from Sunday, June 10, through Friday, June 15, between 11 p.m. and 7 a.m. Crews will excavate and install temporary shoring in preparation for pouring foundations and building retaining walls.

The $147 million project will elevate the Caltrain tracks above three existing at-grade street crossings at San Bruno, San Mateo and Angus avenues. A new elevated Caltrain station between San Bruno and San Mateo a0venues will replace the station at Sylvan Avenue.

Maintenance

Caltrain will perform routine maintenance at several locations next week. To avoid delays to passengers, the work will take place Sunday through Friday from 8 p.m. to 6 a.m. There will be some construction noise but crews will work as quietly as possible.
