Anti-Ram Bollard Installation at an Industrial Zone After a Vehicle Intrusion Incident

At 02:30 on a Saturday morning, a heavy-duty freight truck attempted to enter the zone through the main vehicle gate, which was secured by a standard boom barrier and attended by a single night-shift security guard. The truck did not stop at the guard post. Moving at an estimated speed of 35-40 kilometres per hour, the truck impacted the boom barrier and the guard booth, demolishing both and continuing into the zone's internal road system before the driver — who subsequently fled — was unable to maintain control and brought the vehicle to a stop after colliding with an industrial fence alongside one of the zone's factory buildings.

The incident caused direct property damage assessed at BDT 40 lakh: the guard booth (total loss), the boom barrier (total loss), a 40-metre section of perimeter fencing at the factory building, and damage to the truck-mounted loading crane, which impacted a power line gantry during the intrusion. The security guard on duty sustained minor injuries from the impact and was treated at a hospital.

The truck's contents — subsequently established to be legitimate, if improperly dispatched, cargo — and the driver's motive remained unclear throughout the police investigation. But the physical consequence was unambiguous: a vehicle weighing approximately 12 tonnes had penetrated the zone's primary vehicle access point with zero physical resistance beyond a hinged plastic boom barrier.

The Zone Management Authority's board convened an emergency meeting within 48 hours of the incident. The ZMA's security director presented an assessment that the boom barrier — the standard access control device at virtually all industrial zone vehicle entrances in Bangladesh — provided no meaningful vehicle attack resistance. A standard boom barrier is designed to manage vehicle flow in normal operation, not to physically stop a vehicle that does not comply. Any vehicle driven deliberately into a boom barrier will penetrate it.

The board authorized the security director to procure vehicle access control systems that would physically prevent unauthorized vehicle entry — as distinct from boom barriers that rely on driver compliance. Two BEPZA-regulated zone factories had also raised the issue with the ZMA following the incident, noting that their own insurance policies included provisions requiring the zone to maintain adequate perimeter security. The zone's insurance broker had already informally advised the ZMA that the incident would trigger a review of the zone's vehicle security arrangements.

SSAL designed and installed a vehicle access control system at the main entry of the export processing zone using ASTM F2656 M40-rated automatic rising bollards as the primary vehicle barrier, supplemented by fixed perimeter bollards and integrated LPR and traffic management.

ASTM F2656 M40 P1 Automatic Rising Bollards — 8 Units: Eight automatic rising bollards were installed at the main entry vehicle gateway, in two banks of four — one bank for the entry lane and one for the exit lane. The bollards used are a heavy-duty hydraulic rising type, with a 275mm-diameter Schedule 80 steel bollard shaft and a 900mm strike height above ground level. They are crash-tested and certified to ASTM F2656 M40 P1 — meaning they are tested to stop (penetration less than 1 metre after impact) a vehicle of 6,800 kilograms travelling at 64 kilometres per hour. This is the same specification used for US Embassy vehicle barriers and high-security government facilities.

When raised, each bollard provides a physical obstruction that a vehicle cannot penetrate by any means available to a standard road vehicle. When lowered (to grade), the bollard surface is flush with the road surface, allowing vehicles to pass over the lowered bollard. The hydraulic mechanism is activated from the guard control booth, with a cycle time of approximately 4 seconds from raised to lowered or lowered to raised.

The entry lane operation sequence: a vehicle arrives, the guard verifies the vehicle (see LPR below), the guard operates the bollard control to lower the entry bank, the vehicle enters, the bollards raise behind the entered vehicle. If an unauthorized vehicle attempts to tailgate an authorized vehicle, the bollards are raised between them. If a vehicle does not comply with the guard's instruction to stop, the bollards remain raised and the vehicle is physically stopped.

Fixed Security Bollards — 4 Units: Four fixed (non-retractable) M40-rated steel bollards were installed in a line alongside the perimeter access road adjacent to the main gate — the section of road that leads to the guard booth. These fixed bollards prevent a vehicle approaching the guard booth at high speed from departing the road and approaching the entry barriers at an angle to bypass the rising bollard line.

Hikvision LPR Camera Integration: Two Hikvision DS-2CD7A26G0/P-IZS ANPR cameras were installed — one at the entry lane and one at the exit lane — providing automatic license plate recognition of all approaching vehicles. All pre-authorized vehicles (zone factory registered vehicles, regular delivery contractors, BEPZA authority vehicles) are registered in the ANPR database. When a pre-registered vehicle approaches, the guard control screen shows an immediate green indicator and the vehicle's registration details — enabling rapid authorized vehicle processing. Vehicles not in the database show a red indicator, prompting the guard to verify credentials before authorizing entry by lowering the bollards.

All vehicle movements — entry and exit, plate number, timestamp, and authorization status — are logged in the ANPR database, providing the ZMA with a complete vehicle movement record for the zone.

Traffic Light Signalling: A traffic light system (red/amber/green) is synchronized with the bollard control — bollards raised shows red, bollards descending shows amber, bollards fully lowered shows green. This provides a clear visual signal to vehicle drivers on the approach road, supplementing the guard's instructions with a universally understood traffic signal.

Guard Control Booth — Replacement: A new guard control booth was constructed in the design envelope of the new bollard system, positioned to provide the guard with clear sight lines of both approach lanes and the bollard control panel. The booth is constructed with a reinforced concrete base and steel frame — designed to resist impact from a vehicle that fails to stop at the bollard line (i.e., is physically stopped by the bollards, not the booth).
