From metro stations to commercial precincts, bollards serve as the primary defensive measure for hostile vehicle mitigation. They are strategically designed to balance public safety with the high-intensity movement of pedestrians and vehicles. Let’s understand more on how they protect the high-traffic entry points and what happens in their absence.

What Are Bollards?

Bollards are vertical posts engineered to control vehicle access and protect pedestrians and physical assets. They function as sturdy physical barriers that define the boundaries and provide a clear, high-strength deterrent without obstructing foot traffic.

When protecting public spaces such as Sydney Metro stations, schools, and civic plazas, they also offer a reliable method to secure storefronts against ram-raids and manage private parking assets.

How Are Different Types Of Bollards Utilised?

The selection of fixed, removable, or retractable bollards is determined by the specific access requirements of the facility. 

Primarily, there are 3 types of bollards.

  • Fixed bollards are typically used for permanent asset protection, such as shielding building columns or utility boxes from accidental vehicle impact.
  • Removable and retractable bollards provide a high level of utility for multi-use zones.

Fold-down bollards serve as a practical tool to secure individual parking spaces in high-density areas, ensuring that authorised staff or tenants always have access to their designated bays.

The Role of Bollards in High-Traffic Entry Points

1. Shallow mount technology ensures security without deep excavation.

In the Sydney CBD, the presence of the Sydney Light Rail, fibre-optic cables, and high-voltage power lines often prevents deep digging. Shallow mount bollards solve this by being welded to a wide, flat steel plate buried only 150mm to 300mm deep.

  • When a vehicle strikes the post, the steel engages, using the weight of the surrounding concrete pavement to absorb the kinetic energy and anchor the impact.

This allows government and commercial developers to secure sites without risking damage to critical subterranean services.

2. Absorption & Displacement

For high-traffic entry points, Sydney utilises crash-rated bollards. Unlike regular ones, these are engineered to stop a 7,500 kg vehicle travelling at speeds up to 100 km/h.

  • Bollards here are often embedded up to 600mm to 1000mm into the ground. They are reinforced strategically to transfer the force of an impact into the earth.

Sites often install security bollards under dedicated ‘exempt development’ pathways. This bypasses the need for lengthy council planning applications to fast-track public safety.

3. Stealth Security For Aesthetics

Many bollards in Sydney are disguised or integrated into the urban fabric.

  • They include decorative sleeves where steel cores are covered with stainless steel or cast-iron sleeves.

Additionally, they also match the heritage or modern aesthetics of the surrounding architecture.

4. They are specified by policies.

To ensure Sydney remains inclusively secure, we require bollards to be spaced between 1.2m and 1.5m apart, allowing wheelchairs, prams, and mobility scooters to pass while blocking vehicles. 

Sites often install security bollards under dedicated ‘exempt development’ pathways. This bypasses the need for lengthy council planning applications to fast-track public safety.

What Happens If You Skip on Bollards in High-Traffic Points?

When securing high-traffic entry points, standard posts are replaced with impact-rated systems. This allows you to secure sites without risking damage to critical subterranean services.For example, a high-security installation in a busy Sydney plaza often requires a rating capable of stopping a 7.5-tonne truck travelling at 64 km/h with zero penetration. This means the vehicle is halted immediately without breaching the pedestrian zone.

But what if you decide to substitute them or simply skip their utilisation?

  • You might face significant legal liability and insurance premium hikes if preventable vehicle-related injuries occur on your property.
  • Pedestrian-only zones become vulnerable to unauthorised parking and delivery vehicle encroachment, creating congestion and compromising the safety of high-volume thoroughfares.
  • Lack of physical protection allows vehicles to strike building facades, glass storefronts, and critical utility boxes, causing expensive structural damage.

Secure Your Assets and Lives Around Them

When you are managing a public infrastructure project or a commercial development, the safety of lives and property cannot be neglected. That is why, along with the proper product choice and installation strategy, the experience of a fencing contractor matters. With RIW-certified installers and over 40 years of experience across New South Wales, P&C Fencing is the preferred partner for critical asset protection. Let us help you integrate high-performance HVM bollards into your next project.

FAQs

Q. What is the difference between a security bollard and a standard traffic bollard?

A standard traffic bollard is a visual guide used for traffic calming or lane delineation, often made of plastic or light steel. A security bollard is a structural asset designed for Hostile Vehicle Mitigation (HVM). They are engineered to absorb high-impact kinetic energy and physically stop a vehicle from breaching a perimeter.

Q. Are high-visibility yellow bollards mandatory in NSW warehouses?

Under Work Health and Safety (WHS) regulations, bollards in industrial zones should be highly visible to prevent forklift or truck collisions. While ‘Safety Yellow’ powder coating is the industry standard for compliance, reflective bands are also often required for night-time visibility.

Q. How often do automatic or hydraulic bollards require maintenance?

To ensure reliability at high-traffic entry points, automatic bollards should be serviced every 6 to 12 months. This includes checking hydraulic fluid levels, testing safety loops (sensors that prevent the bollard from rising under a car), and clearing debris from the drainage pit.

Q. Can a single bollard stop a 7,500kg truck?

Yes, provided it is crash-rated (HVM). A single impact-rated bollard is designed to transfer the force of a 7.5-tonne vehicle into a reinforced concrete foundation. A non-rated “security” post would likely shear off at the base under the same force.
