Concrete-Filled Bollard
8.2.1.1
Description. Steel bollards for passive vehicle barriers should be made of 8-inch (20-
cm) or 10-inch (25-cm) diameter, 1/2-inch (1.27-cm) wall, and 7-foot (2.1-m) long steel pipe
filled with concrete. They should extend 3 feet (0.9 m) above the ground level from a 4-foot
(1.2-m) footing, and be positioned 2 (0.6 m) to 4 (1.2 m) feet apart. The footing can be
continuous, but individual footing depth should be at least twice the width, and the width should
be three times the diameter of the pipe, as shown in Figure 25. Bollards can be placed on either
the inside or the outside of existing fences.
