One of the rare departures where the lowest bidder did not win. Lowest bidder was about 56% lower than the second lowest bidder, which also did not win. Again, as with the tender below, the highest bid came from a recently incorporated landscape company.

Company C that won this tender is the same one that claimed to be established since 2005, which was mentioned here: http://openplants.blogspot.com/2018/04/gebiz-spiral-watch.html
But they were incorporated just 4 years ago.
Winner bidded about 35% lower than the second lowest bidder, which seemed to have entered a "troll" bid.
