be a footpath, passageway, walkway, ramp, stairs, landing or
similar.
g)
Discrete Tactile Ground Surface Indicators (discrete TGISs) –
Tactile ground surface indicators that are individually installed,
which provide the same luminance for the sloping sides and
upper surface of the truncated cone.
h)
Front edge (of warning indicator) – This refers to the edge of the
area of warning indicators closest to the roadway.
i)
Height – Distance measured above the finished floor or ground

PRODUCT AND MATERIALS
606.06
GENERAL
1.
TGSIs are designed to provide pedestrians with visual and sensory
information. The two types of TGSIs used by Main Roads WA are warning
indicators and directional indicators.
2.
Warning indicators alert pedestrians to hazards in the continuous
accessible path of travel indicating that they should stop to determine the nature of
the hazard before proceeding further.
3.
Directional indicators give directional orientation to blind and vision
impaired people and designate the continuous accessible path of travel when other
tactile or environmental cues are insufficient.
4.
The visual contrast between the walking surface and surrounding
environment are critical for vision-impaired people who are using their limited
residual vision for orientation, distinguishing the limits of the footpath, recognising
hazards and gathering information. Therefore contrast is especially important in
the provision of TGSIs to warn users of hazards. TGSIs shall provide a high visual
contrast to the adjoining walking surface.
5.
TGSIs shall be installed so that there is no likelihood of the edges
lifting. For this reason Main Roads WA does not approve the use of surface stickon type TGSIs, unless additional mechanical fastenings (eg. screws) are used.
6.
Discrete TGSIs are not to be used on Main Roads WA projects unless
there are contract specific requirements.
7.
Main Roads WA does not recommend any specific TGSI for particular
applications. The Contractor will need to assess which type or style of TGSI is
most suitable for the particular application taking into account substrate, aesthetics,
contrast, availability, consistency with the surrounding area and cost.
8.
An approved list of TGSI manufacturers and available colours that can
be used, based on luminous contrast, for typical background materials in road
infrastructure works is in Annexure 606A.
606.07
WARRANTY OF PRODUCT
1.
The Product (TGSIs) including UV resistance and installation shall be
backed with a minimum warranty of five years. The warranty must be in writing
naming Main Roads Western Australia (Principal) as the product owner.
2.
During the period of the warranty, the supplier shall, without delay and
at no cost to Main Roads Western Australia, correct all defects and omissions
covered by the warranty by way of repair, replacement or modification or other
means. When the product fails any of the requirements of this Specification during
the warranty period the supplier is required to replace the product at no cost to
Main Roads Western Australia.

INSTALLATION
606.20
GENERAL
1.
In Western Australia, on Main Roads WA projects, Main
Roads WA standard drawings supersede those shown in AS 1428.4.1
for the following typical treatments:
606.21
a)
Drawing No.200931-0089, Ramps Type A and Type B
b)
Drawing No.200931-0090, Modified Cut Through Corner Treatment
c)
Drawing No.200931-0091, Median Gaps
METHOD OF INSTALLATION
1.
In the absence of any other documents approved by Main Roads
Western Australia, all components of a TGSI as well as the installation
methodology shall conform to the manufacturer’s requirements.
2.
606.22
The methods of installation shall include;
a)
In-built into substrate (Integrated TGSI tile)
b)
Adhesive Fixing (Integrated TGSI tile)
IN-BUILT INTO SUBSTRATE
1.
MRWA’s preferred method of installation for integrated TGSI tiles is inbuilt into the substrate. For new surfacing the TGSIs shall be in-built at the time of
MAIN ROADS Western Australia
Contract xxx/xx
Specification 606 Tactile Ground Surface Indicators
Document 12/6395 Issue 17/01/17
Page 9 of 18
substrate construction in order to avoid the likelihood of the TGSIs coming off due
to weak adhesion/bonding between the substrate and tiles.
2.
Specific attention should be given to ensuring that the TGSIs are
installed flush with the surrounding surface so as not create a trip hazard.
606.23
ADHESIVE FIXING
1.
To ensure satisfactory bonding of TGSIs to the surface, it is a Main
Roads WA requirement that this method of fixing be supplemented by mechanical
means (eg. use of screws into the substrate).
2.
TGSIs shall be installed with high strength adhesive recommended by
the manufacturer, on a smooth, flat and dry surface to ensure the adhesive has
maximum surface area contact.
3.
For integrated TGSIs, the edge of the base surface shall not be more
than 3mm above the surrounding surface and have all exposed external edges
chamfered.
606.24
MECHANICAL FIXING
1.
In mechanical fixing, TGSIs with a stem or spigot that protrudes into the
substrate are used instead of TGSIs with a flat base. This method is ideal to retrofit discrete TGSIs after the substrate has been laid or on an existing substrate. The
mechanical fixing mechanism may be supplemented through the use of an
adhesive.
2.
For mechanical fixing, drilling templates shall be used as a guide and
correct diameter holes drilled into the substrate to the minimum depth specified by
the manufacturer.
3.
Metal TGSI’s must be thoroughly cleaned with a suitable cleaning
agent (eg; acetone) prior to installation. Any additional adhesive material used
shall be recommended by the manufacturer.
