Replace:

1. c)Edge of traffic lane to road safety barrier system:

1. c)Edge of traffic lane to road safety barrier system:
2. i.0.3 m for a posted speed limit during roadworks up to and including 40 km/h
3. ii.0.5 m for a posted speed limit during roadworks 50 km/h to 80 km/h
4. iii.1.0 m for a posted speed limit during roadworks greater than 80 km/h.

6.6Typical Locations for Signs#

6.6.1Long term#

Signs directed exclusively towards pedestrians must be securely installed at a height which will enable signs to be viewed easily by pedestrians (typically between 500 mm and 1000 mm above the footpath level to the underside of the sign).

6.8Tolerances#

Replace entire Section 6.8 with the following:

Adjustments to a TTM installation are the relocation of signs and devices within approved tolerances. Any changes that exceed tolerances are classed as a modification and must be endorsed and authorised by a TMD. If signs and devices are required to be moved due to obstructions, and relocation exceeds tolerances, the TMI must contact the TMD for instruction on alternate installation methods or options.

Local constraints may not allow signs and devices to be placed exactly in accordance with the relevant TGS. Judgement will therefore be necessary to place signs and devices as close as possible to the locations / spacings indicated. Should variations to the recommended spacing be required then it is generally preferable to increase the spacing within tolerances.

Applicable tolerances include:

1. a)Tolerances for placement of signs are:
2. i.up to 10% less than the distances given, or
3. ii.up to 25% or 15 m more than the distances given (whichever is greater).
4. b)Tolerances for placement of delineation is:
5. i.no minimum and up to 10% more the distances given.
6. c)Tolerances for taper lengths are:
7. i.up to 10% less than the distances given, or
8. ii.up to 25% more than the distances given.

Any sign or device location adjustments are to be marked and initialled on the TGS held on site, with the name of the person making the adjustments clearly shown.

If a TMD has specified maximum or minimum values on the TGS, the TMI must not increase the value above the maximum or reduce the value below the minimum without prior approval from the TMD.
