Bollards can be an effective physical and psychological deterrent, however, there are some situations where bollards cannot be installed.
Typical bollard installation can occur at the kerb or at the front of the building. Spacing of bollards depends on intended use but will need to take accessibility in to account, to prevent vehicle entry needs spacing of 1.4-1.6 metres between bollards.
In many cases one or two bollards in front of a doorway may be all that is required. For installation along building frontages, the council recommends bollards are kept clear of walking areas, usually a clearance of 150mm to 200 mm from the building wall is sufficient. Where bollards are installed at the kerb they should be setback 400mm from the kerb face to avoid unintentional contact by vehicles. Where angle parking exists, bollards are best placed to suit the driver’s side of parked vehicles for increased setback.
To determine if bollards are an option for you and your business you need to:
1. Check if the footpath is clear of obstructions:
Bollards must be installed to leave at least 1.6m of footpath clear for pedestrian access. Existing street furniture also needs to be considered, including poles, bins, signage and removable items such as café tables and chairs.
2. Check that no underground utilities will be impacted by your bollards:
Regardless of the type of bollards you want to install, you must check for underground utilities in the area. Damage to underground infrastructure during excavation or following a vehicle strike is a significant safety risk to the public. Bollards will move when struck by a vehicle and could come into contact with power or gas supply lines.
If there are any underground utility assets within 500mm of your storefront, you will need to have a specific engineering design plan done or consider other possible locations. You may not be able to install bollards.
To check for underground utilities:
- Visit the before U dig website (beforeudig.co.nz)
- Within 48 hours of submitting your job in before U dig, you will receive emails from each relevant utility owner with plans showing any underground utilities in the area where you are planning to install bollards.
- If there are utilities in the area and you want to proceed with installing bollards, we recommend contacting one of the Certified Locators listed on the before U dig website to come and assess your site for a more accurate picture of where the utilities are and whether bollards can be installed safely.
3. Obtain permission from the property owner to install the bollards:
If you are not the property owner, you need to obtain permission from the property owner to install bollards. If the property owner does not give their permission, you will not be able to install bollards.
