Kansas City Load Test Photos Added

BPU Load Test

Last spring, DBA conducted a construction phase load test program for a U.S. Army Corps of Engineers floodwall improvement project  along the Missouri River in Kansas City, Kansas.  Located on property owned and maintained by the Kansas City Board of Public Utilities (BPU), the BPU floodwall was slated for structural improvements including a series of buttresses founded on 24-in drilled shafts.  As part of the project contract a load test program performed under the direction of a qualified P.E. and D.GE was required.  General contractor L.G. Barcus & Sons, Inc., secured our Paul Axtell, P.E., D.GE as the qualified load test expert.  DBA teamed up with load testing subcontractor Applied Foundation Testing, Inc., to perform the static load tests.

The load test program requirements included three test shafts, a statically loaded axial test shaft, a statically loaded lateral test shaft, and a combined statically loaded axial and lateral test shaft.  The required combined lateral and axial test shaft provided some unique challenges with respect to applying the loads and collecting data.  As can be seen in the picture above, the axial load was applied using dead weights.

We have added selected pictures from this unique project to our web albums, which can be viewed here.
