- This module covered the necessary information to understand and gain the knowledge to access, interpret, and apply relevant building codes and standards to the construction process applicable to National Construction Code (NCC) Class 2 to 9 Type C building projects. In this module, you learnt how to classify buildings, determine construction compliance requirements from NCC, and apply fire protection requirements to Class 2 to 9 Type C building projects.
Volumes of the NCC
The NCC incorporates all building work requirements into a single code containing three volumes. The Building Code of Australia (BCA) is Volumes One and Two, and the Plumbing Code of Australia (PCA) is Volume Three.
The Volumes of the NCC covers the following building classifications:
- Volume 1: Volume One of the NCC covers the technical design and construction requirements for all Class 2 to 9 buildings (multi-residential, commercial, industrial, and public assembly buildings) and all their associated structures.
- Volume 2: Volume Two of the NCC covers the technical design and construction requirements for certain residential and non-habitable buildings and structures, specifically Class 1 and 10 buildings.
- Volume 3: Volume Three of the NCC (Plumbing Code of Australia) pertains to plumbing and drainage system of all building classifications.
Australian Standards
Australian Standards (AS) are documents that have been specifically created to outline the specifications that relate to building and construction procedures and products to make sure that they comply with safety and performance standards. Construction procedures are a series of steps followed in a regular definite order to accomplish a construction goal. An example of this is the procedure for cladding a window.
Behaviour of structures under stress
Building structures should be designed using materials to withstand different forces such as compression, tension, bending, torsion, shear and combinations of these forces.
Compression
Compression is the application to different points of a structure of balanced inward ('pushing') forces. Materials such as concrete are often used to withstand compression forces.
Tension
Tension is the application of outward ('pulling') forces on a structure. Steel is often used to withstand tension forces.
Bending
Bending is the forming or forcing of a structure into a curve or angle. Part of the material is under compression and part under tension, so composite materials may be preferred in this situation.
Torsion
Torsion is a twisting or turning force on a structure. Being a more complicated force to deal with, careful design and material selection are important.
Shear
A shear force is a sliding force. One part of the structure has a force in one direction, and another part has a force in the opposite direction. Careful design and material selection are required to withstand shear force.
A combination of these forces is a major cause of the decline of structures' integrity by causing deformation, stiffness, shortening, buckling, breaking, and failure of structures to support themselves and serve their purpose.
Building designers need to be aware of these different forces, and through the calculation of stress and strain, suitable construction materials can be selected. Construction materials have different stress-strain characteristics.
Stress
Stress is the term for the amount of force applied divided by the area over which the force is applied.
Strain
Strain is the ratio between the amount of deformation (due to stress) and the structure's original length.
Australian Standards and other documentation will contain provisions and requirements on ensuring that buildings remain water-resistant and can withstand elements such as stress and exposure.
Codes of State and Territories
Some states and territories also have their own codes relating to residential building and construction projects. Examples of these are the Queensland Development Code, South Australia (SA)’s residential development code, and Western Australia’s residential design codes.
Some of these codes are specific and only apply to the states and territories where they are made for.
Building classes
Here are the building classifications as defined by the NCC.
Class 1: Dwellings
- Class 1A: One or more buildings forming a single dwelling like:
- a detached house; and
- two or more attached buildings separated by a fire-resisting wall, e.g. row house, terrace house
- Class 1B: One or more buildings which together form:
- a guest house, boarding house, a hostel or something similar which does not accommodate more than 12 people and more than 300m2 floor area; or
- four or more dwellings in one allotment, used for short-term accommodations for holidays.
- A Class 1b building cannot be located above or below another dwelling or another building class (except for a private garage).
Class 2: A building containing two or more sole-occupancy units. Each unit must be a separate dwelling.
Class 3: Residential buildings other than Class 1 or 2.
These are long-term or transient living accommodations for unrelated people. These include the following:
- boarding house, guest house, a hostel or backpackers larger than the limits of a Class 1b building
- dormitory-style accommodation or workers’ quarters, e.g. fruit-pickers
- healthcare facilities like accommodations for children, elderly or people with disability which must not be considered under Class 9
- residential parts of motels, hotels, schools, hospitals, or jails
Class 4: The only dwelling or residence within any Class 5, 6, 7, 8 or 9 buildings.
Class 5: An office building used for professional or commercial purposes, except for buildings of Class 6, 7, 8 or 9.
Examples include:
- law office
- office for general medical practitioners
Class 6: Buildings that directly sell goods by retail or supply services to the public.
Examples include:
- restaurants or cafés
- markets, shopping centres and malls
- public laundry
- hairdressers and barbershops
Class 7
- Class 7A: Carparks
- Class 7B: The following buildings are classified under Class 7b:
- warehouses
- storage buildings
- buildings used to display or produce wholesale goods
Class 8: These are process-type buildings.
Examples include:
- buildings used for production, assembling, altering, repairing, finishing, packing or cleaning of goods or produce
- laboratories (classified as such because of their high potential for fire hazard)
Class 9: Buildings of public nature
- Class 9A: Healthcare buildings in which occupants are either:
- undergoing or have undergone medical treatment; or
- in need of physical assistance in the evacuation during emergencies.
- Class 9B: Assembly buildings used for social, theatrical, political, religious, or civil purposes. The following are examples of Class 9b buildings:
- schools
- universities
- childcare centres
- pre-schools
- sporting facilities
- night clubs
- public transport buildings
- Class 9C: An aged care building. An aged care building is defined as a residential accommodation for elderly people who are:
- provided with personal care services; and
- need 24-hour staff assistance to evacuate the building in an emergency.
Class 10: Non-habitable buildings or structures
- Class 10A: Sheds, carports, and private garages
- Class 10B: Structures like:
- fence
- mast
- antenna
- retaining wall
- swimming pool
- other such similar structures
- Class 10C: Private bushfire shelters
NCC Performance Requirements
Building classifications determine the Performance Requirements that you must follow in any given project. Some of the Performance Requirements are only applicable to certain building classifications. Always check with the NCC or an Appropriate Authority if you are unsure which requirements you must apply to your building. Examples include energy efficiency, damp and weatherproofing, fire Safety, health and amenity, structure, safe movement and access and ancillary provisions.
Achieving NCC performance requirements compliance
There are three (3) different ways to achieve compliance with the NCC Performance Requirements. Each method has its uses and may not always be the most suitable option.
- A Performance Solution is one of the choices to achieve compliance with the Performance Requirements of the NCC. This is a tailored solution for a given project situation. This solution is flexible in achieving the outcomes and encourages the use of innovation in design and technology.
- A Deemed-to-Satisfy (DTS) Solution (also known as a Prescriptive Solution) is a standard way to demonstrate compliance with the Performance Requirements. However, there are times when a DTS Solution to a given problem does not exist or does not apply to certain building designs. Sometimes, a unique or site-specific solution is preferred or necessary. In these instances, a Performance Solution may be developed and used.
- A DTS Solution is achieved if you follow all relevant DTS Provisions in the NCC. DTS Provisions tell you what, when, and how to do something to meet the Performance Requirements. These include the materials, components, design factors, and construction methods needed to meet the Performance Requirements.
Performance Solutions compliance assessment methods
There are four (4) types of Assessment Methods that can be used to determine compliance with Performance Solutions and Deem-to-Satisfy Solutions. These are:
- Evidence of suitability
- Expert judgement
- Verification methods
- Comparison with Deemed-to-Satisfy Provisions.
Certificate of conformity
A Certificate of Conformity is a certificate that states an item or product meets the relevant standard. An independent review must be conducted to issue that certificate; however, it is up to the state, territory or relevant authority to accept these certificates as suitable evidence.
Complete documentation to meet NCC requirements
A full copy of the original certificate, report, or document must constitute any copy of the documentary evidence submitted. Inspection documentation is sometimes needed, like a final inspection certificate. To complete the relevant documentation, all the compliance requirements fulfilled by the construction must be documented thoroughly.
Fire protection requirements
Fire safety systems are composed of both passive and active fire control elements that work together to protect a building from damage and its occupants from injury. These must be installed in buildings that are already in use and in buildings that are still undergoing construction.
Passive fire control elements
Passive fire control elements involve the use of suitable materials (e.g. fire-resisting elements and fire doors) in the construction of a building to improve structural stability and reduce the likelihood of collapse. Unlike active fire control elements that aim to extinguish a fire, passive fire control elements aim to contain the fire to its point of origin and prevent it from spreading to the other parts of the building.
This can be achieved through compartmentation, which is the process of breaking the building into areas of manageable risk. These areas are called ‘compartments’ which restrict the growth and spread of fire and smoke, making the fire easier to contain.
In the following you can read about examples of passive fire control elements and their functions in fire protection:
Fire-resisting building elements
Building materials, assemblies, linings, and surface finishes must resist the spread of fire and the generation of smoke.
Non-combustible building elements
These elements have the highest level of reaction to fire performance. They are elements that do not cause flame nor cause any rise in temperature on the material, even in the centre of the material. Examples of materials used with these elements are concrete, ceramics, and masonry.
Fire windows
These protect openings by maintaining the integrity of fire separation and compartmentation. Included are automatic or permanently fixed windows.
Fire doors
These aim to protect openings by maintaining the integrity of fire separation and compartmentation. These include sliding fire doors, their associated warning systems, and associated closing and latching mechanisms. These may be made of a combination of materials such as glass, gypsum, steel, or timber.
Fire shutters
These provide fire separation and compartmentation by automatically closing when a fire is detected. Activation of shutters can be done either by connecting to the building’s fire alarm system or fitted with a heat detection system. Some shutters roll down under their weight. Other shutters operate using a motorised closing mechanism.
Smoke doors
These restrict the passage of smoke between compartments or walls. Included are associated self-closing, automatic closing, and latching mechanisms.
Proscenium walls (fire curtains)
These prevent the passage of smoke and fire from the stage area to the audience area in a theatre.
Active fire control elements
Active fire control elements have a predetermined response to heat, smoke, or specific gases. Some responses are automatic, such as turning sprinklers on and sounding the alarms. Others are manual, such as fire reel systems and portable fire extinguishers.
Active fire control elements can fall under two categories:
- Elements to fight a fire in its early stages are simple and lightweight equipment used by the occupants to extinguish or contain a fire in its early stages. These are typically used while waiting for the fire brigade to arrive. Examples are fire hose reels and fire extinguishers.
- Elements to assist the fire brigade perform their duties. One example is a fire hydrant system.
The next part will discuss some examples of active fire control elements, their descriptions, and their roles in containing the fire.
Smoke and heat alarm and detection systems
These are installed to sense a fire in its initial development stage and warn building occupants. Depending on the size and use of the building the fire alarms may not only warn people in the area but will also alert the fire brigade. This can result in the fire brigade attending site ready to extinguish any fires.
In the event of a false alarm, this can result in additional costs payable for the organisation responsible for the false alarm for the time and resources used by the fire brigade to attend the site.
Fire hose reel systems
These consist of pumps, pipes, water supply, and hose reels. These are placed in strategic locations throughout the building and are manually activated using a valve that enables water flow. They allow occupants to undertake initial fire extinguishment while waiting for the fire brigade.
Portable fire extinguishers
Similar to fire hose reel systems, these allow occupants to undertake initial fire extinguishment while waiting for the fire brigade. These are located in strategic locations, often near a building's main exit and away from areas likely to catch fire. An example of a strategic placement would be placing a portable fire extinguisher at the kitchen entrance but not inside the kitchen.
No type of fire extinguisher can work on all classes of fire. Therefore, you must choose extinguishers with an extinguishing agent suitable to the class of fire that your building is prone to.
The five (5) main types of fire extinguishers in Australia are identifiable by the colour of their bands. These are classified according to their extinguishing agent. The table below shows the different types of extinguishers and the class of fire they are suitable for:
| Type of Extinguisher | Suitable for (class of fire) | Comments |
|---|---|---|
| Water (identified by an all-red body; no band) | A |
|
| Foam (identified by a blue band) | A and B; F (limited effectiveness) |
|
| Dry Chemical Powder (identified by a white band) | An ABE unit is suitable for A, B, C and E fires A BE unit is suitable for B, C, E and F fires |
|
| Wet Chemical (identified by an oatmeal band) | A and F |
|
| Carbon Dioxide (CO2) (identified by a black band) | A and B (limited effectiveness); E |
|
Fire hydrant systems
Fire hydrant systems include an on-site pump set and fire service booster connection. These should only be installed in places with fire brigade access. Fire hydrants provide the fire brigade with a mains water supply.
Emergency warning systems
Emergency Warning and Intercommunication Systems (EWIS) are complex systems installed in larger buildings with automatic and manually controlled functions. The EWIS works in conjunction with a Building Occupant Warning System. Together, these systems detect emergencies and alert occupants to allow for a comprehensive and controlled evacuation during emergencies.
Emergency Warning and Intercommunication Systems (EWIS) are complex systems installed in larger buildings with automatic and manually controlled functions. The EWIS works in conjunction with a Building Occupant Warning System. Together, these systems detect emergencies and alert occupants to allow for a comprehensive and controlled evacuation during emergencies.
In the eventuation that electrical supply is lost during a fire, depending on the purpose and class of the building, there may be a backup power supply usually in the form of a localised battery or an electrical feed coming from an Uninterruptable Power Supply (UPS). These systems undergo 3 or 6 monthly maintenance testing to ensure they are working properly and the backup power supplies are in good working order.
Emergency lighting and exit signs
These signs prevent the occupants’ injury by providing sufficient light and signages during evacuation. All emergency lighting and exit signs must have their own alternative energy supply in case there is a failure in the main supply.
Previously, emergency exit signs used the word ‘EXIT.’ The new updates in the AS now only allow the pictograms as shown.
Automatic fire sprinkler systems
Automatic fire sprinkler systems are installed into the ceiling and are activated when there is an increase in temperature. Once activated, the sprinklers will douse the area with a continuous supply of water until the system shuts off. Depending on where the heat is coming from, will determine what sprinkler heads come on to extinguish the fire.
Automatic fire sprinkler systems may include:
- wet pipe systems and sprinklers
- valve installations
- an electric motor and compression-ignition engines and pump sets
- fire brigade booster connections
- water storage systems
- alarms and interface with automatic fire and detection systems.
Smoke and heat vents
These are openings installed on the roof to discharge smoke and heat generated by the fire. These are also often ties into the fire alarm system, in the eventuation an alarm is sounded these vents will open and exhaust fans will start to clear the area of any smoke.
Standards Australia, in partnership with the Australian Building Codes Board (ABCB), produced an online dictionary of terms for the building and plumbing industry. The dictionary can be accessed here.
