IDIQ Survey of Akutan Boat Harbor
Surveyors from eTrac, a Woolpert Company, traveled twice to the remote Aleutian Island of Akutan to complete a full USACE IDIQ survey of the island's small boat harbor. Getting to and from Akutan involved traveling on two planes, one helicopter, the Alaska Marine Highway Ferry, and finally, a local 24-foot Hewes Craft survey vessel that made the journey across the Bering Sea. As is typical with the Alaska PCS surveys, the team combined a full-coverage multibeam survey with horizontal and vertical control survey via static GNSS and differential leveling, RTK topographic survey, and mobile terrestrial 3D laser scanning. eTrac regularly works in remote areas by shipping a ready-to-go survey equipment kit—the Universal Sonar Mount Expeditionary kit and Vessel of Opportunity kit—to a local vessel captained by the boat owner or one of our operators. eTrac has used myriad local vessels, including landing crafts, fishing boats, personal boats, and inflatable crafts, in remote Alaskan villages. Akutan is a prime example of how we use our Vessel of Opportunity kits to equip local vessels for the duration of remote surveys.
