Why is this important?
Construction is a very expensive endeavor and the average high-rise property will require millions of pounds to be constructed and this is why existing properties, have to be properly protected by building security in London in order to ensure that no unnecessary damage is done to those properties. For the interior of that property, access control and internal patrols will be necessary in order to discourage actions by employees which could have undesirable consequences. Likewise on the outside of that building frequent patrols will be necessary to discourage criminals, vagrants and the homeless. Especially the homeless is constantly on the lookout for available lodgings and it will be the duty of building security in London to prevent a situation where this people gain access to such an empty property.
What is most important?
Obviously the most serious threat is from outside and whether the property is occupied or not, building security in London will have to take the necessary steps to protect that property from criminal and other undesirable characters. Sometimes the homeless is allowed to occupy such an empty property, but even then it will be necessary to have measures in place to ensure that no unnecessary damage is done to the structure such as electrical cables or water pipes which could be sold by the homeless in order to generate a modest income. It will be the duty of building security in London to prevent these kinds of criminal actions from taking place. If there is not proper control of such a property, then in a relatively short time such a property will be nothing more but an empty shell.
What about occupied properties?
Most large properties is full of valuable things which can be very attractive to criminals and also to the homeless. When there is an obvious lack of effective building security in London, then criminals or the homeless will not hesitate to exploit those opportunities and to enrich themselves by removing some of that property and then selling it to interested buyers. These criminal actions has to be prevented at all cost and everything possible has to be done by building security in London to maintain that property in an excellent condition. If this is not done the cost of repairs, maybe so high that it may no longer be cost-effective to have that property repaired so that it can be used for human occupation.
