Integration of redeployable security fencing with vehicle barriers to protect

against hostile vehicle threats

Contents • Introduction

• Fencing – the issues

• Redeployable security fence – features / benefits

• Installation / access portal

• Upgrade to vehicle protection – testing

• Use as a temporary vehicle barrier

• Examples

• Conclusion

Permanent fencing Crowd control barriers

• Slow to install • Requires posts to be set or

driven • Easily damaged during breach

attempts • Easily climbable • Cannot redeploy once erected • No resistance to hostile

vehicle penetration

• Lacks height • Easily toppled • Possible injury and breach • No protection to personnel

behind • Open configuration • No resistance to hostile

vehicle penetration

Event Fencing Ideal solution

• Easily climbable • Offers some security • Minimal foundation • Requires bracing (usually) • No visibility to threat • No resistance to hostile

vehicle penetration in many cases

• Easily & quickly deployed • Extremely difficult to scale • Requires no foundations • Cannot be penetrated or toppled • Offers protection to security personnel whilst

maintaining visibility • Provides resistance to vehicle penetration

Fencing – the issues

Redeployable security fence

Anti-climb front face

Multiple heights available

Secured using bulk bags

Connecting pins inaccessible

Collapsible structure allows flat pack

Benefits • Flat packed – easily and quickly erected

• No fence posts – rapid deployment

• Reusable – lower whole life costs

• Anti-climb front face - protection, visibility + delay and sophistication to any attack

• Location of joining pins – anti tamper

• Uses local ballast – reduced shipping weight

• Portal – allows perimeter access

• Vehicle rated – vehicle security at fence line

Assembly Sequence

Typical installation rates 2.4 metres = 40-50 linear metres / hr 3.6 metres = 25-30 linear metres / hr

• Comes flat packed

• Stand up 3 cell unit (3.9 m) in length

• Insert spirals

• Stand up next unit

• Insert joining pin

• Load bulk bags

Pedestrian Access Portal • Allows access

• Creates potential weak point

• Strengthened using “portal”

• Move to location

• Fence erected around portal

• Easily defended and blocked

Pedestrian Access Portal

Upgrade for hostile vehicles

• Vehicle attacks are increasing

• HRSF easily upgraded

• Simply add more weight to cells

• How weight interacts is key

• PAS 68 : 2010 tested

PAS 68 : 2010

• Truck two axle rigid

• Vehicle Class [N2]

Test regimes

• UK BSI PAS 68 (2010) – Impact test standard

• UK BSI PAS 69 (2013 out shortly) – Site survey and installation guidance

• European CWA 16221

• US ASTM F2657-07 (2007)

• International IWA

Pedestrian access portal PAS 68 : 2010

• 4 x 4 pick up

• Vehicle class [N1G]

Use with vehicle barriers • Can be used with main types

– Bollards

– Road Blockers

• Adapted to be surface mounted

• Quick to install

• Utilises adapted HESCO Lo

• 1.2 m height

Adapted design for surface mounting

Bollards - testing PAS 68 : 2010

• Truck two axle rigid

• Vehicle Class [N2]

• Surface mounted road blocker

• Integrated into HESCO Lo fence line

• Allows controlled access

Road blocker - testing PAS 68 : 2010

• Truck two axle rigid

• Vehicle Class [N2]

Why?

• Short time frame needs quick install

• Limited timescale event – Known or unknown risk

– VIP visits to insecure locations

• Heightened threat for limited time period – Unacceptable residual risk if do nothing

• Whilst installing permanent measures – Risk still exists

– Increased amount off traffic

– Unknown hostiles

Use as a temporary vehicle barrier

• Non-surface install may require more time than available

• Unknown quantities – power

– drainage

– water

– other services

• Necessitates survey prior to excavation

• Surface mounts eliminate this need

• Eliminates cost associated with re-routing services
