If the location is remote or has a large perimeter it often provides the opportunity to incorporate landscaping to mitigate the ability for a vehicle to gain entry and/or reduce the potential speed of approach for a vehicle. Measures such as landscaping can alleviate the need to employ large scale and heavy duty HVM measures whilst providing critical vehicle ‘stand-off’ from the building/asset. A perimeter of a site can be additionally protected with a high security fencing incorporating intruder detection and CCTV. Limiting vehicle access to the site is essential and therefore serious consideration should be given to the number of access points provided. These considerations should also take into consideration the needs of emergency vehicle and vehicle reject lanes. Any access point needs to be protected and controlled effectively by using products that meet both the physical/operational requirements along with the aesthetical and engineering constraints that the site might pose. Where a building is in a city centre or urban area and space around the building is at a minimum, other measures can help protect and increase vehicle ‘stand-off’ these might including: planters, street furniture or static bollards. Equipment used to control access to data centres, whilst still offering a high level of protection against hostile attack using a vehicle includes: – · · Road blocker systems with a variety of options (deep/shallow and surface)· Automatic and static bollards
· Sliding and hinged gates
· Rising arm barriers
· Manual gates and barriers
· Plus – a large range of non-rated products to complement and enhance site control
