Throw Back Thursday

For our first "Throw Back Thursday" post, we go all the way back to 2010 with the Dick Henderson Bridge project in St. Albans, WV.  It was our first Mobile LiDAR collection from the water.

Our client already had a barge on-site to support inspection and other activities.  Therefore, we were able to simply drive the vehicle onto the barge and collect the underside of the bridge in a matter of a couple hours.  Using painted survey targets on the bridge, we seamlessly merged the data from the barge with data collected on the bridge.  In a previous post titled "West Virginia - Preliminary Information", the trajectories from the two collections are presented.

The data was utilized to help develop design alternatives for public consumption.  They can be viewed on the West Virginia Department of Transportation website.  Furthermore, the information aided in the development of a demolition plan, including a controlled blast.

As mentioned in Tuesday's post, it is rewarding to see the completed projects.  The bridge officially reopened in October 2013, as covered by the Charleston Gazette Mail.

Cheers!
