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.

Biloxi Bay Bridge Test Pile Program – DFI Journal Volume 3, May 2009

Robert’s paper with Lloyd Held (retired from Eustis Engineering) and Steve Saye of Kiewit Engineering Company on the Biloxi Bay Bridge test pile program has been published in the latest issue of the DFI Journal, published by the Deep Foundations Institute.  A total of 22 indicator piles were installed on the project using the pile driving analyzer to monitor the pile behavior. Five load tests were performed: two axial Statnamic, two lateral Statnamic, and one static axial. The results of the test pile program established driving criteria for production piles that included end of drive blow counts and pile tip elevations with an appropriate allowance for setup.

kcICON Bond Bridge Update – Drilled Shafts Complete!

UPDATE (5/19/09): Here is an article the Kansas City Star on-line.  It has links to photos and video.
Main Pylon under construction for Bond Bridge, Kansas City, MO

Work by DBA is all but compete on the kcICON project.  All drilled shafts have been installed and base grouted. Construction of the shafts went very well, with no significant issues.  Hayes Drilling installed all of the land-based shafts.  AFT performed all of the base grouting.

The main pylon in the river continues to take shape.  It won’t be long before PCC will have it looking like a bridge!

Paul has been “enjoying” observing drilled shafts at night and base grouting during the day.  A collection of some of his photos from the last bits of shaft construction are below.  He got some great shots of the pylon, including some out in the river.
