Luminance Contrast is the amount of light reflected
from one surface, measured against another adjoining
surface.

The measure of Luminance Contrast can vary when
different conditions are experienced eg., wet and dry
surfaces provide different readings, different readings
will occur during the day as compared to the night
(particularly when insufficient artificial lighting levels are
provided — refer to AS1428.2-1992 for a guide to
lighting levels)

A ramp is an inclined accessway with a gradient no
steeper than 1 in 14 and landings every 9 metres and
no shallower than 1 in 20 and landings every 15 metres
and where the grade is in between these gradients the
landing distances are calculated using linear ‘
interpolation. The minimum width between handrails on
a ramp must be 1200mm and the minimum length of a
landing (continuous handrails) must be 1500mm or
1800mm (non-continuous handrails).

Where the overall length of a ramp exceeds 50 metres
a resting point with a seat and a wheelchair space
complying with AS1428.2-1992 must be provided every
25 metres. These resting spaces must be protected
from the sun and weather and be outside the
continuous accessible path of travel.

A shoreline is a term used to describe the bounding of
a pathway, accessway or continuous accessible
pathway of travel and includes elements such as kerbs,
walls, windows, plantings, raised garden beds,
pedestrian barriers etc.

Any step of one riser or more is regarded as a stairway
unless it is a single step which has a step ramp
incorporated and the step ramp is constructed in
accordance with AS1428.1-2001 and is either located
along a shoreline or if no shoreline is provided the entry
points are identified with both directional tactile ground
surface indicators from the shoreline to the step ramp
and also warning tactile ground surface indicators in
accordance with AS1428.4-2002.

Due to the nature and use of this project, a stairway
must be accessible if it is built in any public space or in
any common space in a residential component of this
project.
