Case file
Boom barriers, sliding and swing gates, road blockers, bollards and turnstiles — integrated with ANPR, RFID and access control.
/ The discipline, in detail
How we approach boom barriers & motorised gates.
Vehicle entry is the single highest-throughput interaction at any property. We design barriers and gates to the actual peak flow — opening time, MCBF (mean cycles before failure), safety photocells, loop sensors and obstacle-detection. ANPR or RFID handles the credential read; the barrier handles the physical motion. Crash-rated bollards and road blockers are specified at K4/K8/K12 ratings where the threat profile demands.
On record
Every boom barriers & motorised gates engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.
/ Where we deploy this
Active across 5 sectors.
Boom Barriers & Motorised Gates is rarely a standalone brief — it sits inside a wider sector practice with its own codes, expectations and operating rhythm.

/ Frequently asked
Boom Barriers & Motorised Gates — what buyers ask first.
How fast should a boom barrier open?
A high-speed boom barrier opens in 1.5–1.8 seconds for corporate gates at 200 vehicles/hour peak; 3-second barriers create queuing at that flow. A 3-second barrier creates queuing at peak. A 1.5–1.8 second high-speed barrier handles the same flow without backup. We size barrier speed to peak vehicles-per-minute, not catalogue spec.
How fast should a boom barrier open?
1.5–2.5 seconds full open is the right answer for most premium gates — fast enough that authorised vehicles don't queue, slow enough that the mechanism lasts. Sub-1.5-second high-speed barriers exist for very high-throughput sites but wear faster and cost more in AMC. We size to the actual vehicle flow.
How many cycles per day can a premium boom barrier handle?
Premium barriers (Came, Nice, Magnetic Autocontrol) are rated for 3,000–10,000 cycles per day depending on duty class. A typical commercial gate runs 200–800 cycles. We specify duty class against year-3 expected flow, never to launch-day estimates.
How is the barrier interlocked with the rest of the gate sequence?
Through a documented logic in the access-control platform: ANPR confirms plate, UVSS confirms clean, access database confirms authorised, vehicle-detection loop confirms presence — only then does the barrier open. Loops on either side of the barrier prevent it from closing on a vehicle. Every interlock is programmed and tested at commissioning.
Crash-rated barriers — when are they appropriate?
For embassies, military bases and certain government and corporate HQs where vehicle-borne threat is part of the realistic threat model. Crash-rated bollards (M30, M50) and crash-rated barriers (PAS 68 / IWA 14 standards) are engineered to stop a 7,500 kg vehicle at 50 mph. The civil work for proper anchoring is significant; we coordinate with the structural consultant.
What's the AMC scope for a high-traffic gate?
Quarterly inspection (motor health, gearbox lubrication, induction-loop calibration, beacon and barrier-arm condition), annual full overhaul (motor brushes, gearbox seals, electronic-control replacement schedule), and 24/7 on-call during AMC for high-traffic sites. We hold spare motors, controllers and arms for active deployments.
