SANS 10400 regulations, General Principles and Requirements

SANS 10400 Regulations Governs the Design, planning and supervision of all construction work

Each section of SANS 10400 regulations, the Code of Practice for The application of the National Building Regulations (NBR) is presented with the relevant extract from the building regulations (which is the law), and is then followed by a general commentary explaining how the law should be interpreted to “satisfy” the law.

Generally, the regulations themselves are remarkably short, while the deemed-to-satisfy rules (now referred to as deemed-to-satisfy requirements) are quite lengthy. But in Part A of SANS 10400 regulations, General Principles and Requirements, the regulations cover about 15 pages. By contrast, the regulations section relating to excavation covers just half a page.

You can download the standards (as published in 1990), as well as the most recent version of the regulations (the Act) published in its entirety, HERE, as well as the recent amendments to the Act. Just be aware that while the amendments to the regulations are complete, the SABS commentary in these documents, which explains how the regulations should be interpreted and applied, is not.

You can buy specific sections of the most recent edition of The application of the National Building Regulations SANS 10400 regulations 2011 from the SABS, either at one of their offices or online at the SABS Internet store.

What is Covered in Part A: General Principles and Requirements

This section of the NBR (SANS 10400 regulations)covers details of requirements for plans, drawings and various documents that MUST be submitted to your local authority before you are allowed to build any sort of structure. For instance, you need to have:

• a site plan,

• layout drawings,

• a fire installation drawing,

• drainage installation drawings,

• particulars of any existing building or structure that is going to be demolished – and you need to state how it will be demolished,

• and any other plans and particulars that your local authority requires.

These SANS 10400 SANS regulations general principles and requirements also specify the details that must be included on different plans, as well as the size and scale required on plans and drawings. They also state what colours to use to identify different materials on plans. For instance, new masonry must be shaded red and new concrete green. All existing materials are shown in grey.

When architects, designers and engineers draw plans, they use symbols to identify certain details. These are also specified in SANS 10400 regulations Part A.

There is also information regarding building control officers and their qualifications; specifications relating to plumbers and anyone doing plumbing work – only trained plumbers are permitted to do this work – specifications of who may design buildings, as well as inspect and assess them.

 Changes to SANS 10400 regulations Part A of The application of the National Building Regulations

Previously referred to as SABS 0400-1990, these regulations were totally overhauled in 2008 and are now SANS 10400 regulations. This meant that the deemed-to-satisfy elements had to be overhauled and rewritten too. The reasons given for the overhaul were:

• the fact that the apartheid system had been abandoned

• the fact that South Africa’s population had doubled since the regulations were first written

• the fact that local authorities throughout the country had been completely restructured

• formation of the National Home Builders Registration (NHBRC)

• the introduction of much more complex building control and systems

• the introduction of an increasing number of innovative, new construction system for building

Everybody Has A Right To:

Furthermore, Section 24 of the Bill of Rights in the South African Constitution states that everybody has a right to: “an environment that is not harmful to their health or well-being”. So if our buildings aren’t healthy, and aren’t built with our health and welfare in mind, they are essentially unconstitutional!

Perhaps the greatest change – certainly the one that will impact on both individuals and the building profession – is the fact that all applications to build must now be accompanied by a declaration by a person registered in terms of a built-environment professional council, as to how the applicable functional requirements are to be satisfied.

All plans must also be submitted by a “competent person” who is professionally registered in terms of the Engineering Professions Act, the Architectural Professions Act, or the Natural Scientific Professions Act. So unless you are a qualified architect, engineer, designer or somebody specifically with the required “education, training, experience and contextual knowledge” to judge whether a dwelling will meet the functional regulations, you are not a competent person!
