6.3Scope of traffic guidance scheme#
TGS shall be prepared in accordance with the requirements of the Queensland MUTCD Part 3 and QGTTM shall align with the site specific TMP.
The TGS shall show traffic control device layouts (including TRSB, temporary pavement marking and temporary islands), be fully dimensioned and shall generally agree with the construction sequence and other requirements shown elsewhere in the Contract.
The TGS shall also state the period for which the traffic control devices are to be in place (time and date) and the person who is responsible for installing, maintaining and removing them. Work site access arrangements shall form part of the TGS.
The TGS shall also identify those traffic control devices which are only to be in place during periods of actual work on site. Signs such as symbolic workers signs and speed limits, introduced due to reduced clearances to workers, should be covered or removed during periods when workers are no longer on site (for example, at night). The Principal requires that speed limits are applied strictly in accordance with the QGTTM Part 3 Clause 5.5.1, unless accompanied by a supporting risk assessment and RPEQ approval or sign off.
Where the TGS includes changes to regulatory signs or devices, the Contractor shall include roadwork signing records in accordance with the QGTTM Part 6 and the Queensland MUTCD Part 1 Appendix B certified by the Nominated Traffic Officer.
Where speed enforcement mechanisms such as an RBMS camera or Police enforcement are to be deployed at a site, a specific TGS shall be developed in accordance with the requirements of the QGTTM, noting that the requirements of TC2320 shall also be included in the design.
