Work has begun to construct temporary piers to support the I-43 Leo Frigo Bridge. Pier 22 of the bridge settled approximately 2.5 feet in late September/early October. The new piers are being constructed by Lunda Construction. The goal of the structures is to prevent any additional settlement of the deck. The bridge will remain closed pending a permanent solution. The ENR article did not list what the piers will be founded on, but the conceptual drawings available from WisDOT seem to show drilled shaft foundations. [Source: ENR: Engineering News Record.

Voids Open as a Result of Tunneling Under Seattle’s Beacon Hill

May 7, 2009 rockman Project Related Comments Off on Voids Open as a Result of Tunneling Under Seattle’s Beacon Hill

image The Seattle Times (hat tip to ASCE SmartBrief) has reported that seven voids have been discovered above the Beacon Hill Tunnel with one opening up at the ground surface. The tunnel is being constructed by Sound Transit, the area’s transportation agency as part of a roughly $2.6 billion (yep, billion) light-rail project connecting downtown Seattle with the University of Washington and SEA-TAC airport. The voids were a result of running sand pockets in the otherwise stable clay units that were encountered by the tunnel boring machine or TBM. These voids migrated up like a chimney with one reaching the surface, almost 160-ft above the tunnel. This void was apparently 21-ft deep and opened up in a resident’s front yard and could have easily swallowed her up as she noticed it while gardening. The other voids were discovered at a depth of 20- to 65-ft below the ground surface. More after the break. (Illustration from Seattle Times)
