For the past 8 years Hydrau-Tech, Inc. has conducted over 105 Plan of Action (POA) studies for scour critical bridges and for bridges with unknown foundations. After the 2013 floods in Colorado, Hydrau-Tech inspected over 80 bridges for scour damage and provided scour mitigation for 60 bridges. Currently, Hydrau-Tech is providing detail design for scour mitigation to 40 bridges across the entire State of Colorado. Highlights of this experience are available in Hydrau-Tech’s bridge scour experience brochure.
The HT_POA_Sites file provides an interactive map of all Hydrau-Tech, Inc. scour critical bridge sites for which a POA was prepared. The file can be opened and viewed using Google Earth on a phone, tablet, or computer (Google Earth must be downloaded and installed on whichever device is being used, it is available for free here). After opening the file in Google Earth, selecting a bridge Placemark will display the bridge characteristics, a site image, and links to the site’s report documents and additional images. Note that sites with a red icon are part of the most current POA task order.
