   8.5 Traffic Control Devices

   8.5.1   Sign Requirements

All signs used shall conform to the designs and dimensions as shown in Australian Standard AS 1742.3,
QGTTM, AGTTM and the CoP.

Prior to installation, all signs and devices shall be checked by the Site Supervisor or a suitably qualified person
to ensure that they are in good condition and meet the following requirements: -

              Mechanical condition - Items that are bent, broken or have surface damage shall not be used.
              Cleanliness - Items should be free from accumulated dirt, road grime or other contamination.
              Colour of fluorescent signs - fluorescent signs whose colour has faded to a point where they have lost their
               daylight impact shall be replaced.
              Retroreflectivity. - Signs used for night-time or in low light conditions whose retroreflectivity is degraded
               either from long use or surface damage and does not meet the requirements of AS 1906 shall be replaced.
              Battery operated devices - shall be checked for lamp operation and battery condition.
Where signs do not conform either to the requirements of AS 1742.3 or would fail to pass any of the above
checks, they shall be replaced on notice.

Signs and devices shall be positioned and erected in accordance with the locations and spacing’s shown on
the drawings. All signs shall be positioned and erected such that:

              They are properly displayed and securely mounted.
              They are within the driver’s line of sight.
              They cannot be obscured from view.
              They do not obscure other devices from the driver’s line of sight.
              They do not become a possible hazard to workers or vehicles; and
              They do not deflect traffic into an undesirable path.
Signs and devices that are erected before they are required shall be covered by a suitable opaque material.
The cover shall be removed immediately prior to the commencement of work.

Where there is a potential for conflict of information between existing signage and temporary signage erected
for the purpose of traffic control, the existing signs shall be covered. The material covering the sign shall
ensure that the sign cannot be seen under all conditions i.e. day, night and wet weather. Care will be taken to
ensure existing signs are not damaged by the covering material or by adhesive tape.

   8.5.2   Tolerances on positioning of signs and devices

Where a specific distance for the longitudinal positioning of signs or devices with respect to other items or
features is stated, for the spacing of delineating devices or for the length of tapers or markings, the following
tolerances may be applied: -

       (a) Positioning of signs, length of tapers or markings:
                         (i) Minimum, 10% less than the distances or lengths given.
                         (ii) Maximum, 25% more than the distances or lengths given.
       (b) Spacing of delineating devices:
                         (i) Maximum, 10% more than the spacing shown.
                         (ii) No minimum.
These tolerances shall not apply where a distance, length or spacing is already stated as a maximum, a
minimum or a range.
