Rules for semi-automatic bollards in Northern Ireland
Bollards on public footways and roads need DfI Roads consent under the Roads (NI) Order 1993; councils deal with planning. On private land the owner's agreement is what matters; listed buildings and conservation areas need a word with the planning team first. Accessibility guidance asks for posts at least 1,000 mm high with contrasting tops and no chains between them.

How installation works
Survey use and ground
At the free site survey we look at how often the post will be used, who will operate it and what is under the surface. A fixed written quote follows, including drainage.
Set the cassette
The cassette is set plumb and flush with the finished surface, connected to drainage and concreted in. The strut is fitted or released only as the manufacturer instructs.
Reinstate the surface
Paving or surfacing is made good tight to the cassette collar so there is no lip for tyres or feet to catch.
Test and show users
The post is cycled several times to check it rises fully, locks at both heights and lowers smoothly. Users are shown how to operate it and to keep clear of the head when it rises.

Who do I ask about bollards on public land in Derry City and Strabane?
DfI Roads (the Department for Infrastructure) is the roads authority for public roads and footways throughout Northern Ireland; councils handle planning.
Can a semi-automatic bollard injure someone as it rises?
It rises with some force, so nobody should stand over it or put a hand on the head when releasing it. Users should be shown how to operate it safely. On busy sites, a sign and reflective bands help.
What makes a semi-automatic bollard rise without power?
A gas strut or spring inside the cassette. Pushing the post down compresses it and a latch holds the post below ground. Turning the key releases the latch and the stored energy lifts the post.
