Bollards are a sturdy option for creating a barrier when you don’t want a fence or need something sturdier. Issues can arise, however, if you don’t space your bollards correctly. And, unfortunately, there is no “one size fits all” option for spacing bollards. Bollards that control access at a hospital require different spacing than those that protect a loading dock, and both of those uses have different spacing than bollards on a busy street in front of a store. If you’re considering bollards, read on for three great tips to keep in mind as you plan for them.
Spacing to Manage Traffic
Most bollards are installed to control vehicle traffic in some way. For this purpose, bollards are usually spaced about five feet apart. That gap will stop almost all vehicle traffic, including those tiny Smart cars from passing through. It does still allow for pedestrian and even bike traffic to pass through (on the flip side, this means that motorcycle traffic can also fit through). This is the normal installation in areas such as the front of stadiums, around parking lots, and in front of stores. Since they need to be able to withstand a vehicle collision, you should only use high-security bollards for this purpose. As an aside, if you allow pedestrian traffic, your bollards need to be at least three feet apart to allow wheelchair access or they will not be ADA compliant.
Spacing for Protection
Bollards are often used to protect something, such as a utility object, an art installation, or even the building itself if there is a lot of backing up traffic (such as at a loading dock). More often than not, these bollards are spaced more closely together than those that control vehicle traffic. If the thing you’re protecting doesn’t need to allow pedestrian access, the bollards can be spaced much more closely together. You can also connect bollards with chains to further dissuade pedestrians from crossing – this is a common choice in areas where people are not supposed to walk on the grass.
Spacing Considerations for Emergencies
Finally, if you are installing bollards in an area that could be an emergency exit, there are some special spacing concerns. There always needs to be a way for people to safely exit the area, including people in wheelchairs, so make sure your spacing is ADA compliant. You may also want to consider using removable or retractable bollards to allow for emergency vehicles to pass the perimeter if needed.
