Recent Project Photos – (or) What have we been up to the last few months (Part 1)?…… Drilled Shafts!

If you frequent this blog, you have noticed that posts have been rare the last few months.  That is mostly to my being in the field a lot this summer and very busy on lost of projects.  While that is good, it meant I did not have time for updates.  Below are some slide shows from a few drilled shaft projects we worked on this summer.

 

Garden State Parkway Mullica River Bridge, New Jersey – Test Shaft Installation

Paul took a trip to lovely New Jersey to observe a large diameter test shaft on the Mullica River Bridge.  DBA worked as a consultant for Parsons Brinckerhoff on an 8-foot diameter, 220-foot deep test shaft.  CASE was the drilled shaft contractor and Agate was the general contractor.  DBA consulted on the design of the test shaft program, as well as the use of Self Consolidating Concrete (SCC).

 

 

Drilled Shaft Lateral Load Test Research with the University of Kansas

Paul took a ride out west to Kansas City, Kansas (close to home!) to observe a drilled shaft lateral load test in Wyandotte County, near the Cabela’s store on I-435.  The test is part of ongoing research by the University of Kansas for the Kansas DOT.   DBA was involved in previous research concerning laterally loaded shafts behind MSE walls (see previous post, click here for more information on the project).  This research continues on the same theme of investigating the behavior of laterally loaded shafts socketed into the sedimentary rocks in eastern Kansas.  DBA does not have an active role in this project, just an academic interest. 

 

 

 

Huey P. Long Bridge Improvements, New Orleans, Louisiana – Test Shaft Installation

The Huey P. Long Bridge in New Orleans (built in the 1930s) is undergoing a major rehab and expansion.  The vehicle traffic will increase from 2 9-foot lanes in each direction to 3 11-foot lanes in each direction.  This is a very interesting combined highway and railroad bridge with a fascinating history.  The bridge is actually a private bridge owned by the New Orleans Public Belt Railway (click the link to see some cool photos from the construction of the bridge in the 1930s). The project website is here. 

DBA was consulting with the joint venture building the bridge for the base-grouted drilled shafts under one new pier.  A test-shaft was built and tested with O-cells.  Robert was on site while they excavated the test shaft.  Steve was on site during grouting.
