Access Design

When designing buildings, EnvironArc strives for “no barriers”, so people can have dignified access in accordance with the Disability Discrimination Act.

Access design utilises the Building Code of Australia and AS 1428 and ISO 7001. Another valuable tool is the “Good Play Space Guide”.

Design must provide a continuously accessible path of travel to or within a building, providing access to all facilities and services required to be accessible. Basic design requirements include car parks, doorways and ablutions.


wheelchair access
International symbol for access – also known as the (International) Wheelchair Symbol, consists of a blue square overlaid in white with a stylized image of a person using a wheelchair. Details of the design, colours and location of this symbol can be found in AS 1428.1

hearing impaired
International symbol for deafness – this symbol should be used to indicate the availability of an assistive listening system such as a hearing loop.

Tactile ground surface indicators (TGSIs) –raised surface domes or cones on the ground designed to provide warning information about features such as stairs, ramps or hazards to pedestrians who are blind or who have vision impairment.

Additional design initiatives may include, but not be limited to:

Assistive listening system (ALS) is a means of improving speech intelligibility at the ear of a listener. This is normally achieved through the process of reducing background noise and reverberation and increasing volume.

An example would be a Hearing Loop or infra-red system. A Hearing Loop system assists people using hearing aids to hear more clearly by cutting out background noise. A loop system can be set up with a microphone and a transmitter to send signals via the system, which are then picked up by hearing aids switched to ‘T’ setting. In larger event situations, infra-red systems that allow for stereo sound may be more practical.

Telephone typewriter (TTY) is a machine with a keyboard and screen. It may be built into a telephone or be connected to one. A person who is Deaf or hearing impaired, or someone with a speech impediment, can use the machine to communicate with another person who also has a TTY by typing the message and reading the reply. TTY users can call people who do not have a TTY by using the National Relay Service provided by the Australian Communication Exchange (ACE). This allows the person to send or receive messages from ordinary ‘voice’ telephones. See ‘Further information’ for more information on TTY and the National Relay Service.

EnvironArc has worked with the City of Marion, Town of Walkerville, the Copper Coast Council, the City of Onkaparinga and the City of Salisbury for specialist access design works like new lifts, toilets, parks, buildings and car parks.
