Childs Engineering performed both a pre-demolition survey and a post-demolition survey in Fort Point Channel, adjacent to the Northern Avenue Bridge Tender’s House. As part of the project for the partial demolition of the Tender’s House, this work was done to ensure that no debris was deposited within the waterway and if so, have it properly removed. A side-scan sonar survey was conducted to identify any debris above the mudline and any targets of interest were then verified with a diver. A partial hydrographic survey of the waterway was also done during the post-demolition survey. Through comparison of the sidescan sonar pre and post demolition surveys, it was determined that no debris was deposited within the waterway during the partial demolition of the Tender’s House.

Project Type: Hydrographic Survey
