Here is one of the more interesting features we have scanned over the years: The Headworks at Sir Adam Beck Hydroelectric Generating Station.
The reservoir was drained for scheduled maintenance, which involved surveying the floor and retaining wall integrity.
Ontario Power Generation (OPG) contracted Rankin Construction, who in turn hired us to perform a photogrammetry survey of the site.
This structure was not the main area of interest, but we were still able to capture enough data to generate this model.
Hope you enjoy.
