measures for project-specific risks. For example, funding
crime prevention may be more important than funding
terrorist prevention countermeasures for some projects.
Cost-Risk Analysis. Actual costs may be more or less
than budgeted. This cost risk results from the need to
predict bidding market costs years in advance, evolving
technology, changing risks, different countermeasures,
and varying project conditions. The "Standard Practice for
Measuring Cost Risk of Buildings and Building Systems,"
ASTM E 1946, may be used to manage cost risk.
Site Planning and Landscape Design
IMPORTANT NOTE: The following criteria do NOT apply to all
projects. Follow each criterion only if instructed to by your
project-specific risk assessment. Many criteria are based on
the recommendations of a specific building risk assessment/
threat analysis. Where the criteria include a blank or offer a
choice of approaches, the recommendations from risk
assessment will provide information for filling in the blank or
suggesting a choice of approaches.
Effective site planning and landscape design can enhance
the security of a facility and eliminate the need for some
engineering solutions. Security considerations should be
an integral part of all site planning, perimeter definition,
lighting, and landscape decisions.
