What we check first in Larne
Across Northern Ireland the Department for Infrastructure's DfI Roads is the roads authority, so shallow-mount bollards on a public footway or road in Larne need its agreement before anything is dug. Posts on your own land do not.
Planning in Northern Ireland sits with the councils, so for a listed building or conservation area in Larne the planning team at Mid and East Antrim Borough Council is the one to ask before posts go in.
Shallow does not mean simple. The trench has to sit over services with enough cover to protect them, but the frame also needs a firm, consistent bearing; soft spots, old backfill around pipe trenches and voids under paving can all need treating first.
- Check gaps work for wheelchair users and buggies while still stopping vehicles, referring to Inclusive Mobility guidance.
- Record the frame's position on as-built drawings so future excavation near the line can be planned safely.
From survey to handover
Map what is underground
Utility records, radar scanning and trial holes establish exactly how much depth is available along the line. This is the survey that decides whether a shallow system will fit at all.
Cut and excavate the trench
Paving is lifted and kept for reuse where possible, and a shallow trench is excavated by hand near known services. Where a service sits higher than expected, work stops and the detail is referred back.
Pour, cure and reinstate
Concrete is placed to the specified grade and finish depth, then the surface is rebuilt to match. The line is protected until the specified curing period has passed.
Choosing the right spec
| Option | Detail |
|---|---|
| Surface-mounted rated units | Some tested products sit on or very close to the surface with minimal digging. These are often used for temporary or semi-permanent protection and need careful checking of the surface they bear on. |
| Linked-frame systems | Posts are welded or bolted to a continuous steel frame laid in a shallow trench and encased in concrete. Suited to straight or gently curved lines. |
| Modular cassette sections | Pre-made sections joined on site, allowing short runs and changes of direction within the manufacturer's tested limits. |
What affects the quote
Two Larne jobs with the same number of posts can price quite differently. The usual reasons:
- Changes of direction, end details and removable positions
- Lifting, storing and relaying natural stone paving
- Length of run and the system needed to achieve the rating
Keeping them working
If one post is struck, the frame may have transmitted load to its neighbours, so the whole run near the impact should be checked with the manufacturer rather than replacing a single post in isolation. Pay attention to the surface around the posts, because settlement or loose paving can indicate movement in the bearing layer.
We can also service, repair or replace existing posts anywhere in Larne.
Questions about shallow-mount bollards in Larne
Which parts of Larne do you cover for shallow-mount bollards?
We cover all of Larne (BT40) and the rest of Mid and East Antrim. We also work in Carrickfergus, Newtownabbey and Antrim.
Do I need consent for shallow-mount bollards on a public footway in Larne?
Kerbside work in Larne is a DfI Roads question: the Department for Infrastructure is the roads authority for Northern Ireland, and its permission is needed for anything placed in the public road or footway.
What's a typical price for shallow-mount bollards in Larne?
In Larne, typically £1,945–£8,795 per bollard position, supplied and installed, plus VAT, with a minimum job of £4,895 plus VAT, using our Northern Ireland guide prices. The fixed figure comes in writing after we've seen the site.
Can I install a single shallow-mount bollard on its own?
Usually not. Most shallow systems rely on several posts working together, and the rating applies to a tested run with a stated minimum number of posts. A single position generally needs a different solution.
Will future roadworks damage the system?
They can if contractors dig beside it without knowing it is there. That is why we provide as-built drawings showing the frame position. Ask anyone excavating nearby to check those drawings first.
