Bollard - Cap & Base Dimensions & Drawings

Comparison drawing of Cap & Base Bollard compared to similar bollard types

Description

Cap & base round bollards, featuring a cylindrical post with thicker extruded elements at the top and bottom, merge utility and unique aesthetics. The cap and base add visual prominence and architectural interest, enhancing their role as traffic guides and pedestrian protectors. These design elements also improve visibility, enhancing safety. Their rounded shape reduces injury potential in pedestrian-heavy areas. Available in various materials and impact resistance levels, these bollards serve as decorative features, boundary demarcations, and effective security barriers.

Dimensions & Sizes

Cap & Base Bollards have varied widths of 9.5”, 12.63” (24, 32 cm) and overall heights of 42”, 44.5” (107, 113 cm). The inner post is sized at 8.5”, 11.63” (21.6, 29.5 cm) with a base height of 5” (12.7 cm). Concrete foundations for Cap & Base Bollards are typically 4” (10.2 cm) below grade.

Bollard Spacing

Bollards are typically spaced at a distance of 36”-60” (91.4-152.4 cm) between bollards. The heights of bollards are commonly in the range of 30”-48” (76.2-122 cm).

Common Questions

How much force can a bollard stop?

The force a bollard can stop depends on its design, material, and installation depth. High-security anti-ram bollards, usually made of steel and deeply embedded into the ground, can withstand impacts from vehicles traveling at high speeds, even up to 50 mph. Some are tested to stop a 15,000-pound vehicle, effectively resisting an approximate force of 1.2 million foot-pounds at impact.

How do telescopic bollards work?

Telescopic bollards work using an in-ground, retractable design. When not in use, they retract into the ground, becoming flush with the surface. To raise them, a key unlocks the mechanism, allowing the bollard to be manually lifted and locked in an upright position. This flexible mechanism allows for control of vehicle access while maintaining pedestrian accessibility and aesthetic appeal.

Why are bollards filled with concrete?

Bollards are filled with concrete to increase their strength and stability. The concrete acts as a reinforcement, making the bollard more resistant to high-impact forces, such as a vehicle collision. This is crucial for security bollards that safeguard sensitive areas. Additionally, concrete-filled bollards provide a robust, low-maintenance solution that can withstand various environmental conditions.

How do public spaces support people?

Public spaces are areas that are open and accessible to the general public and built to provide a place for people to gather, socialize, and engage in activities. They can also provide amenities such as seating, restrooms, and water fountains that make it easier for people to spend time in these spaces. Public spaces can also serve as a hub for community events and activities, such as concerts, festivals, and sporting events that can contribute to the overall well-being of the people who use them.

What is ‘privately owned public space (POPS)’?

Privately owned public space (POPS) is a term used to describe outdoor areas that are owned by private entities, but are open and accessible to the public. These spaces can include plazas, courtyards, and other outdoor areas that are located on private property but are intended for public use. While POPS are privately owned, they are typically subject to specific regulations that govern their use and maintenance, and they are required to remain open and accessible to the public during designated hours.

What does ‘building accessibility’ refer to?

Building accessibility refers to the design and layout of a building and its facilities to ensure that they are accessible and usable by people with disabilities. The goal of building accessibility is to ensure that all people, regardless of their ability level, are able to enter, move around, and use the facilities within a building. Building accessibility is often regulated by law, and buildings are required to meet certain standards in order to be deemed accessible.
