Viaduct Inspections Show Settlement Problems Long Before Tunneling

Conceptual drawing of Bertha rescue shaft

The Alaskan Way Viaduct tunneling project was in the news late last year when settlement of the Viaduct was reported during the dewatering efforts for the Bertha TBM rescue shaft. A recent post by WSDOT makes it clear that the settlement of the viaduct has been a problem for many years before the start of construction. The most recent round of monitoring by WSDOT began in 2001 after the completion of repairs to the the Viaduct following the Nisqually Earthquake. By 2006, a total of 4 3/4 inches of settlement had been recorded at one location. It appears that the rate of settlement is on the order of about 1/8 inch to 1/4 inch per year. I am sure the dewatering around the access pit didn't help the problem, but it looks like it didn't create it by itself either. This information just underscores the importance of the tunnel project to replace this aging structure. [Source: WSDOT Alaskan Way Viaduct. Image: WSDOT and STP via KPLU]

Lab Scheduling Press Release atmisRedditch 30th Jan 2015 - The new release of HoleBASE SI includes ‘scheduling tools’ that allow engineers to electronically schedule geotechnical or environmental testing. This major breakthrough is likely to transform the way consultants and laboratories communicate with each other over the coming months.

The new improvements also provide a glimpse of how well integrated customers and laboratories can be with the first UK wide implementation of a web service connection to ALcontrol’s @mis online laboratory data management system. . This unique development allows customers to schedule testing directly into the @mis system using data and tools inside of HoleBASE SI and then be notified within HoleBASE SI when the testing is completed.

Cofferdam for the Tapan Zee Bridge

The geotechnical software company Deep Excavation has a nice entry on their blog about the cofferdams for the Tapan Zee Bridge in New York. Geotechnical firm Siefert Associates used the DeepExcav software to design the cofferdams which are needed to create the pile cap for the new bridge piers.

ADSC Foundation Drilling Magazine - January Cover

The excavation has been completed for the access shaft or rescue shaft that was needed to be able to remove the damaged cutterhead of the Bertha TBM on the Alaskan Way Viaduct Replacement project in Seattle. The target depth of 120 feet was reached on January 30. WSDOT reports that settlement levels have remained stable in the pit area after an earlier settlement issue. In addition to the project update on the WSDOT project page, there is an excellent article on the work done by Malcom Drilling to construct the shafts used to form the excavation walls in the January issue of Foundation Drilling Magazine. I highly recommend that article. You can also see some neat raw video from WSDOT below.
