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.
The Bollard was created in 2005.
Alan Bollard was born in 1951.
A bollard is a short vertical post used to block vehicles, to prevent travel in an area or to avoid damage to something behind the bollard. Bollard covers protect the bollard from superficial damage and weathering, and are not a particularly new technology.

It is a "bollard." The hawser (rope) is attached to the bollard to anchor a ship in position at a pier or wharf.

Bollard pull is typically calculated using the formula: ( BP = \frac{(T \times V)}{33000} ), where ( BP ) is the bollard pull in pounds, ( T ) is the thrust in pounds, and ( V ) is the speed in knots. To convert bollard pull to horsepower (HP), you can use the formula: ( HP = \frac{BP \times V}{550} ), where ( V ) is in feet per minute. Thus, bollard pull and horsepower can be connected through their relationship with thrust and speed.
anchor handling winch and winch wire is designed based on bollard pull requirement. winch wire breaking strength is 2 to 2.5 times of bollard pull force. anchor winch brake holding is 1.5 time of bollard pull or 80% of wire breaking strength
A bollard is a short, vertical post, usually made of wood, steel or concrete. The are used for mooring ships as well as traffic protection devices.
