2.4 BOLLARD ANALYSIS
Bollards are protective and visual architectural elements that prevent the entrance of certain vehicles by emphasizing the boundaries of traffic pathways, mainly to protect people and properties.
They are prevalent in modern urban environments and come in different sizes. Despite the variety of materials that can be used to make bollards, the most common materials are concrete, metal, stone, or plastic. These materials are selected due to their ability to withstand high-force impacts

To acquire a comprehensive understanding of the bollards, which will serve as the foundation for the shading unit, YTER Company, the manufacturer of the bollards, was contacted. Through this process, a plethora of information was obtained, including details on different bollard types, technical specifications, information on ground attachments, and the materials used for finishing. This information was crucial in informing the design and selection of the most suitable configuration of the OSTRA sunshade. Contact person: Rafael Malaga (SP).
After consulting with the fabrication company of the bollards and conducting research on their structure and properties, it was determined that the average weight of the bollards located in front of the Delft station is approximately 200 kg. The ground fixing of these bollards is also confirmed. As a result, it was concluded that adding a column to support the design of the OSTRA sun-shade on these bollards will not pose any issues or complications.
