In many organizations, the cost of data center security is a shared expense —or at least it should be. How much then should you be spending on security and how much of that should be picked up by other business units?

However, I would recommend adding 20% to that number for any unforeseen, outside of contract maintenance costs.
For future project budgeting, you should be able to get a hold of what your facilities department has planned for projects that require physical security and estimate what the security costs related to those projects will represent. You will need to determine what the unique physical security requirements are for each project because they can vary however, using 1.0-1.5% of a total projects construction cost should suffice.
The cost you incur as opposed to what is charged back to projects and other departments will generally fall into the below four categories:
