Competent person


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


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


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

Tensions associated with standards development

Owners / developers

dont want to payanything more

Practioners wantsomething simple

and quick to apply

standard

Academics wishto get things

19/22

Impact on industry

Amended NBRs and revised SANS 10400 provide

construction standards and standard details aroundwhich curricula, qualifications and training courses may bedeveloped

a more flexible approach which facilitates innovation andthe introduction of new technologies

greater certainty regarding the acceptability of products

20/22

Impact on owners and users

Amended NBRs and revised SANS 10400

providea more transparent, consistent and equitable
