ERG’s Security Risk Design (SRD) Framework is used to assess new and existing buildings, infrastructure and space during design, construction, and operations. An SRD assessment supports the design of security solutions that are justified, necessary, proportionate, legal and cost-effective. This risk-based approach supports the achievement of better security outcomes, return on investment, positive security culture and a greater certainty of effect. Such a design system is focused upon the effect resulting from each element of an integrated solution. This commitment to protect people, infrastructure and critical assets provides assurance to stakeholders, demonstrates care for the public and aids regulatory compliance.
