Originally expected to be finished this month, the realignment of the Folsom Street off-ramp is now expected to run into June and the budget for the project has been increased 21 percent, from $2,883,900 to $3,479,541.
The delay and cost overruns are primarily due to the discovery of higher than expected levels of motor oil and lead in the soil below, soil which has been stockpiled and covered on site, as pictured above, for testing and proper disposition. And the piles are preventing work on the off-ramp from proceeding as planned.
The Folsom Street off-ramp realignment will clear the way for the 550-foot tower designed by Architect Rem Koolhaas and the Office for Metropolitan Architecture (OMA) to rise on the Transbay Block 8 site, with the potential for a Whole Foods on the corner.
Discussions with Caltrans regarding the ultimate responsibility for the contaminated materials and the cost for its disposition are “ongoing,” according to a memo from the Executive Director of the city’s Office of Community Investment and Infrastructure.
