There are no set recommendations to determine the correct placement, spacing and alignment of bollards. Applying the correct spacing between each bollard or from a boundary wall or pillar, will vary from project to project, although the industry has created guidelines for the optimal placement and spacing of bollards to ensure the level of security and safety you are looking for is not compromised.
To ensure, the level of security is not compromised, you need to plan for a 1.2 to 1.3 mtr drive through gap between each bollard, boundary wall or pillar.
To ensure the vehicles on your driveway are protected, you need to plan for a 1.3 to 1.5 mtr drive through gap between each bollard, boundary wall or fence post.
To ensure your building is protected against an attempted ram raid attack, you need to plan for a 1.2 to 1.3 mtr drive through gap between each bollard or boundary.
Every project is different, we advise that you follow our guidelines, consider the drive through gap for your application, and just apply basic common sense to decide what the actual drive through gap should be. Freedom of movement for pedestrians will also need to play a part in how you plan your project.
