TOOLS – SITES
In the case of security projects, the starting point is protective security solutions in layers.
Protective security layers typically combine different types of security measures, the purpose of which is to deter, detect, delay and/or stop an attacker, as well as to reduce the consequence of an attack.
A security solution will often combine certified / tested / calculated elements and elements that impede and delay the route towards the target but are not necessarily dimensioned to stop, e.g., a vehicle attack. Delaying functions should be supported by detection measures. The security project must be carried out in compliance with prevailing legislation, including, e.g., building regulations and accessibility requirements.
Below you will find several tools (protective security measures) that can be used to secure both public and private outdoor areas – primarily with a focus on preventing vehicle attacks and unauthorised entry.
The security measures shown can be combined as required to create a coherent, holistic security solution, integrated into the site and project design.
Terrain –Excavation
Shallow Entry V Ditch
Acts as a deterrent as well as a stopper when designed with a wall height of at least 0.5 m and a length of the slope/ditch as per the guidelines from the Danish Security and Intelligence Service, PET.
Basin
Acts as a deterrent, as well as a stopper, when designed with edges with a wall height of at least 0.5 m or slopes with a slope height as per the guidelines from the Danish Security and Intelligence Service, PET.
Trapping pit
An area designed and dimensioned for vulnerable traffic users or possibly as a decoration, that will collapse under the pressure of a traversing vehicle.
Terrain –Elevation
Bund
Acts as a deterrent, as well as a stopper, when designed with a slope height of at least 1.25 m and with a graded slope as per the guidelines from the Danish Security and Intelligence Service, PET.
Landscape mound with edge
Acts as a deterrent, as well as a stopper when designed with a wall height of at least 0.5 m.
Elevated planter
Act as a deterrent, as well as a stopper, when designed with a wall height of at least 0.5 m.
The planter can be reinforced with the help of anchoring/foundations, increased soil volume or integrated bollards.
Single elements
Bollard
Fixed or retractable bollards.
Act as a deterrent, as well as a stopper.
Art
Impedes and delays.
Should be secured to the ground, so they cannot be moved.
Planting
Impedes and delays. Larger trees placed close together can have a stopping effect.
Urban furniture
Impedes and delays.
Possibly reinforced via anchoring/foundation, dimensioning, etc.
Speed reduction measures
Impede and delay.
Also taking into consideration the projected layout, e.g. access conditions.
Security turntables with fixed elements
The turntable is designed so that in one position it allows access, while in the other position it blocks.
The blocking element of the turntable can be designed as a place where people can hang out.
Fencing
Wall, fence, etc.
Acts as a perimeter/access restriction.
Be aware of evacuation/escape options.
Temporary Elements
Concrete guardrail
Hampers and delays – can stop when correctly fixed to the terrain. Should be used with caution in terms of both flow and accessibility.
Retractable wedge
Hampers and delays – can stop objects when correctly fixed to the terrain. Should be used with caution in terms of both flow and accessibility.
