The Responsible Person (RP) is the legal owner/occupier of the Special Development / Special Infrastructure. Some of the duties of the Responsible Person include:

• Ensuring specified works commence only with Commissioner (Infrastructure Protection)’s approval of the security plan
• Seeking Commissioner's approval for the Competent Person(s) preparing the security plan
• Ensuring compliance to other laws and regulations in Singapore

The RP should review the suitability of the security and blast consultants based on the nature of works for the Special Development or Special Infrastructure. 

The list of consultants who have met the minimum competency requirements as Competent Person is available under the References and Application Forms section below. This list is only for reference and all appointments of Competent Persons are subject to the approval of the Commissioner of Infrastructure Protection on a case-by-case basis, in connection with the specified works. The list of consultants does not constitute legal, professional or commercial advice, and MHA will not be liable for any loss or damage resulting from the use of this information. 

The RP may also engage any security or blast consultants who are not on the list, and their competency will be assessed on a case-by-case basis to determine whether they are suitable during their application to be appointed as a Competent Person. For the avoidance of doubt, consultants in the list are not automatically approved as a Competent Person. The assessment process for security or blast consultants who are not on the list will take approximately two months.

A Competent Person is approved by the Commissioner of Infrastructure Protection to prepare security plans and certificates of works completion for a special development or special infrastructure. Competent Persons are usually security or blast consultants and may be in-house or commercial consultants.

Those applying to be Competent Person (Security) and Competent Person (Blast) will be subject to security screening and must fulfil the following minimum competency requirements:

• Possess relevant experience (in recent 3 years) in the preparation of security plans under the MHA Security-By-Design review process; or
• Possess relevant subject matter expertise and knowledge, with accredited referee reports or internationally published professional work [depending on the nature of the project]; or
• Must be registered as an Accredited Security Consultant (Security Consultant Accreditation Program) or a Specialist Professional Engineer (Protective Security) with Professional Engineers Board.

Under the Infrastructure Protection Act, security plans for special developments or special infrastructures must be prepared by a Competent Person(s). Competent Persons are approved by the Commissioner of Infrastructure Protection in connection with the specified works on a case-by-case basis.
