While these posts have a functional purpose, they can also contribute to the overall design and aesthetics of a space. Bollards have recently become an increasingly important element in architectural design as they are used for safety, security, and aesthetic purposes.
This article will explore what bollards are, their different types, and some uses of bollards in architecture. So keep reading to discover more about bollards in architecture and design.
Historical Overview Of The Bollard
Believe it or not, bollards have been in use for hundreds of years dating back to ancient times when they were used to moor boats and ships. In mediaeval Europe, bollards were also used to mark boundaries of different areas and to protect buildings from horse-drawn carts.
In the 19th century, the use of bollards expanded with the growth of industrialization and the development of modern transportation. These posts were used to mark the boundaries of railroad tracks, to protect buildings from wagons and carriages, and to control traffic on streets.
During World War II, bollards became an important tool for security in order to protect buildings and people from the threat of bombings. Large concrete bollards were used to create barriers and prevent vehicles from entering restricted areas.
Today, these posts have become an important element of urban design and architecture. They are used to define spaces, to create visual interest, and to enhance safety and security in public spaces. Bollards are ubiquitous in today’s cities and are often designed with a range of materials and aesthetics to complement the surrounding architecture.
Types Of Bollard Used In Architecture
Bollards used in architecture come in various types and can be differentiated based on their design, materials, and function. Below we’ve outlined some of the most common types of bollards used in architecture:
Fixed Bollard
These are permanent bollards that are installed in the ground and can’t be moved. They’re typically made from durable materials like concrete, steel, or cast iron and can be used for security, traffic control, or aesthetic purposes.
Removable Bollard
These can be easily removed and replaced as needed. They are often used in areas where access needs to be controlled like in pedestrian areas or event spaces.
Retractable Bollard
These can be raised or lowered to allow access to a restricted area. They are commonly used for vehicle entrances and can be operated manually or electronically.
Decorative Bollard
These are designed to enhance the aesthetic appeal of a space and are often made from high-end materials like stainless steel or bronze. They can be used to create visual interest or to complement the surrounding architecture.
Illuminated Bollard
These feature built-in lighting elements and can be used to enhance safety or for aesthetic purposes. Illuminated bollards are often used in pedestrian areas or to highlight important architectural features.
Flexible Bollard
Flexible bollards are designed to bend or flex on impact, making them ideal for areas where there is a risk of vehicle collisions, such as bike lanes or parking lots.
Material Selection For Bollards
The material used to make bollards is an important consideration as it impacts the durability, appearance, and function of the bollard. Here are some of the most commonly used materials for bollards in architecture:
Concrete
Concrete is a durable and cost-effective material that can withstand harsh weather conditions and impact from vehicles. Concrete bollards can be moulded into various shapes and sizes, making them a versatile option for architects.
Steel
Steel is a popular choice because of its strength and durability. It’s commonly used in areas where security is a concern, such as government buildings or public spaces.
Cast Iron
Cast iron is a traditional material due to its durability and decorative qualities. It can be intricately designed and can add visual interest to a space.
Stainless Steel
Stainless steel is a great material as it’s resistant to corrosion. It can be polished to a high shine or given a matte finish for a modern look.
Recycled Materials
Bollards can also be made from recycled materials like plastic, rubber, or glass. These materials are environmentally friendly and can add a unique look to a space. However, they may not be as durable as traditional materials.
Safety and Security
Bollards are commonly used for safety and security purposes in architecture. They can be installed in public spaces, government buildings, and private properties to prevent unauthorised vehicle access, protect pedestrians from traffic, and enhance security. Here are some of the ways bollards are used for safety and security:
Anti-Ram Bollard
Anti-ram posts are designed to prevent vehicles from entering a restricted area by absorbing the impact of a vehicle collision. They are commonly used in high-security areas lik3 government buildings and airports.
Crash-Rated Bollard
Crash-rated posts are designed to withstand the impact of a vehicle travelling at high speeds. They are commonly used in facilities like power plants and chemical plants.
Traffic Control Bollard
Traffic control posts are used to manage vehicular traffic and prevent accidents. They can be installed at intersections, pedestrian crossings, and parking lots to guide traffic and protect pedestrians.
Pedestrian Safety Bollard
Pedestrian safety bollards are used to protect pedestrians from vehicles by creating a physical barrier. They can be installed on sidewalks, in parks, and around buildings.
Access Control Bollard
Access control bollards are used to control vehicle access to a property or restricted area. They can be installed at entrances and exits to ensure only authorised vehicles are allowed to enter.
Aesthetics And Landscape Design
Bollards are not only used for safety and security but can also be used to enhance the aesthetics of a space and landscape design. They can add visual interest, create a sense of place, and provide a connection between the architecture and the surrounding environment.
Decorative Bollard
Decorative bollards are designed to be visually appealing and can enhance the aesthetics of a space. They can be made from a variety of materials and can be customised to complement the surrounding architecture.
Landscape Bollard
Landscape bollards are designed to blend in with the natural environment and can be used to create a sense of place. They can be made from materials like natural stone and can be designed to complement the surrounding landscape.
Wayfinding Bollard
Wayfinding bollards are used to guide pedestrians and can be designed to provide information about a space. They can be customised with signage or lighting elements to ensure they’re easily visible to passersby.
Artistic Bollard
Artistic bollards are designed to be a work of art and can add a unique element to a space. They can be made from a variety of materials and can be customised to reflect the theme or history of the surrounding area.
Choosing The Right Bollard For Your Needs
Bollards are an essential component of any urban design or traffic management plan. They offer a range of benefits, including safety, security, and aesthetic appeal. However, choosing the right bollard for your needs can be a daunting task.
There are many different types of bollards available, each with its unique features and benefits. Below, we’ll explore some of the key factors you should consider when choosing the right bollard for your needs.
Purpose
The first step in choosing the right bollard is to determine its purpose. Bollards are commonly used for a range of applications, including traffic management, pedestrian safety, perimeter security, and decorative purposes. The purpose of your bollard will determine its size, shape, material, and installation requirements.
If you’re looking for a bollard to manage traffic flow, you’ll want to choose a robust and highly visible option, such as a steel bollard with reflective strips. If you need a bollard to enhance the aesthetics of a public space, you might opt for a decorative bollard made of stone or concrete.
Location
The location of your bollard is another critical factor to consider. The location will determine the weather conditions that the bollard will be exposed to, as well as the level of traffic or pedestrian activity in the area.
If your bollard is located in a high-traffic area, you’ll want to choose a durable and impact-resistant option like steel or concrete bollards. If your bollard will be located in an area with high moisture or salt exposure, like in a coastal environment, you might consider a bollard made of stainless steel to prevent corrosion.
Material
The material of your bollard will also play a significant role in its durability and functionality. There are many different materials to choose from, each with its unique features and benefits.
Steel bollards are highly durable and impact-resistant, making them an excellent choice for traffic management and perimeter security applications. Concrete bollards are also highly durable and can be used for decorative purposes, but they are more challenging to install and relocate.
Other materials to consider include aluminium, which is lightweight and easy to install, and plastic, which is highly impact-resistant and low maintenance.
Size and Shape
The size and shape of your bollard will depend on its purpose and location. Bollards come in a range of sizes, from small decorative options to large, heavy-duty models.
For traffic management and perimeter security applications, you’ll want to choose a bollard that’s large enough to be highly visible but not so large that it obstructs the flow of traffic or pedestrian movement.
The shape of your bollard will also play a role in its functionality. Round bollards are highly visible and easy to install, whereas square or rectangular bollards can be used to define spaces and create visual interest.
