Competent person
8/4/2019 Presentation Ron Water Meyer
11/22
Competent person
a person who is qualified by virtue of his education, training,experience and contextual knowledge to make a determination
regarding the performance of a building or part thereof inrelation to a functional regulation
In many jurisdictions, Building Control Officers or Proof Engineersreview the work of professionals for compliance with buildingordinances or codes e.g. in the UK.
A competent persons is encountered where professionals self
certify their work for compliance with requirements
A scan of international practice is that the Canada, Scotland,Hong Kong, and USA entry level admission to a profession is
insufficient to deem a person competent to perform structuraldesign
8/4/2019 Presentation Ron Water Meyer
12/22
Competent person
Amended regulations require competent person to
have PI unless an employee of the owner
be professionally registered in terms of the EngineeringProfessions Act, the Architectural Professions Act or theNatural Scientific Professions Act
be adequtately qualified and have sufficient contextualexperience to perform assigned tasks
not be under investigation by a disciplinary tribunal of astatutory council
NBRs look to SANS 10400 to further define a competent person
The safety of South Africas buildings hinge on the competence
and integrity of those entrusted to self certify compliance with the
national building regulations
8/4/2019 Presentation Ron Water Meyer
13/22
Applications to local authorities (Regulation A2):
Applications must be accompanied by a declaration by a personregistered in terms of a built environment professions council as to
how the applicable functional regulations are to be satisfied
Declaration
Indicates
- Complexity of the project (low, medium or high)- Site sensitivity in environmental or heritage terms (low,
medium, high)
- The precise manner in which each and every applicablefunctional regulation will be satisfied (rules, competentperson, Agrment certification, alternative design)
Lists all appointments of competent persons that are to be made
