On average a bollard can be installed by a licensed contractor paying comp and liabilty ins. for about 400.00 ea. This price includes the bollard at a height of 4' above ground and 3' below ground.
Bollards come in many sizes and for many different purposes. You could easily install one yourself and pay maybe $200, for example https://www.slowstop.com/products/bollard-kit-1, which would be a small surface mounted application, or pay many thousands for a K-Rated security bollard (http://www.calpipebollards.com/K12-Rated-Bollards.html). It all depends on your application.
A contractor would probably charge in the range of $400 assuming he had to core out the concrete, bury the pipe and backfill.
You could install a surface mounted bollard yourself with only a hammerdrill and impact wrench, although not all surface mounted are strong enough. Get the rebounding type.
The Bollard was created in 2005.
Alan Bollard was born in 1951.
