Layered perimeter protection
The August 2018 bulletin explains how fences, walls, bollards and raised features can create a continuous perimeter and separation from vulnerable assets. Anti-intrusion barriers delay access, giving responders more time. Design choices should reflect the site’s actual exposure and operational needs.
Static and active vehicle measures
Reinforced planters, landscaping, walls or hardened street furniture may provide anti-ramming protection while preserving pedestrian access. Gates, drop-arm barriers and retractable bollards can control vehicle entrances. The source refers designers to the Guidelines for Enhancing Building Security in Singapore; use the latest official version for an actual design.
