Hastings Update and Photo Album

Well, I, David, have survived my first (and hopefully last) winter in Minnesota.  I spent most of January and February observing the installation of the Pier 5 drilled shafts at the new Hastings bridge project in Hastings, Minnesota.  In addition to the drilled shafts, there has been a lot activity at Hastings since Aaron last blogged about this project in January.  A link to his post is here.  All of the ground improvement piles for the column-supported embankment have been installed and approximately 75% of the caps have been poured.  The 42-inch piles and pile caps for Piers 8, 9, and 10 are also complete.  Piles for the north embankment retaining wall have been installed and construction of the wall has begun.  Excavation for the rock bearing spread footings that will support the south land piers is in progress.  Work at Piers 6 and 7 and on the north shore are currently on hold as the Mississippi River is experiencing its annual spring flood. The water level is about 14 feet above normal elevation.

I have taken the pictures Paul and I have collected over the last few months and uploaded some of the more interesting ones to a Picasa web album.  The pictures are generally in chronological order and cover most of the construction process from November of 2010 right up to the end of March 2011.  A link to our our video of a Statnamic load test at Hastings that Aaron blogged about is here.
