Might be nothing more spectacular than a drainage channel for all the surface/rain water collecting on the site and the building at the end of the site might be a pumping station to pump the water out into any public drainage System they have. Might make sense to run such a collector for the length of the site.
With deep foundations that required piledrivers, which are usually only required for heavy, multi-story buildings or for industrial buildings that host heavy machinery?
