Campbell Section 5 - Works Approval Project Ref: 110029Prepared for the Land Development Agency8.5.4 Constitution Avenue / Creswell StreetIt is proposed that a median be introduced on Constitution Avenue at the end of Creswell Street bythe ACT Government. This aligns with the aspirations for Constitution Avenue outlined in the NCAConstitution Avenue Public Realm Handbook and the PSP by AECOM. This median will force alarge proportion of the traffic to reroute through the Campbell Section 5 development and to use thesignalised intersection at Wendouree Drive / Constitution Avenue.8.5.5 Constitution Avenue / Wendouree Drive / Road 3This intersection of Constitution Avenue and Wendouree Drive is to be upgraded to a signalised 4-way intersection under spate contracts as part of the Parkes Section 49 ASIO improvements, andACT Government upgrades to Constitution Avenue.8.5.6 Creswell Street / Getting Crescent / Road 2-(C)A new road linking the Campbell Section 5 development into the existing 3-way intersection ofCreswell Street / Getting crescent is required. It is proposed that a 4-way roundabout be installed toupgrade this intersection. The existing kerb alignment on the eastern side of Creswell Streetadjacent to existing properties will be maintained as far as possible. Refer to Drawing 110029/C1343for the intersection plan.8.6 Traffic signalsIt is proposed that upgrades to the intersection of Constitution Avenue / Wendouree Drive / Road 3will be upgraded by the ACT Government to operate as a four way signalised junction as outlined inSection 6 Transport, Traffic and Planning, prior to the works outlined in this Works Approval Report.8.7 Traffic control devicesRefer to drawing 110029/C1800 - 01All proposed traffic control devices have been designed to comply with Roads ACT requirements,and relevant Australian Standards and Austroads guidelines.8.8 Pavement designDouglas Partners has undertaken geotechnical investigations including laboratory soaked CBRtesting and assessment of the composition and residual life of the existing road pavement.Details of these investigations and recommendations are included in Appendix 4.Refer to drawing 110029/C1300 for the proposed pavements.The design assumes where new pavement is to be constructed next to an existing; the existingpavement will be milled prior to laying the final AC layer over both the new and existing pavements.Surface and subsoil drainage will be installed and maintained to protect the pavement and subgrade.Subsoil drains should be located at a minimum of 0.5 m depth below the excavation level.November 2012 Cardno 76
Campbell Section 5 - Works Approval Project Ref: 110029Prepared for the Land Development Agency8.9 Street lightingA concept street lighting design has been developed and ActewAGL is undertaking the detaileddesign. The street lighting design will be issued upon completion by ActewAGL.New street lighting to Campbell Section 5 is proposed to consist of 150 watt metal halide SylvaniaElipt street light luminaires for the roadways, and 50 watt metal halide Bega 8180 post top luminairesto the open space pathways. The spacing of the pedestrian lighting will be designed to the worstcase lighting scenario for LED and metal halide, allowing for future flexibility to change the fittings toLED.The system will be designed to comply with AS.1158, Part 3.1, for a Category P4 installation. Fullcut-off lighting will be specified throughout to reduce light pollution and night glare.The installation will be designed to comply with AS.3000 (Wiring Rules) TAMS’ Design Standard forUrban Infrastructure, Street Lighting, Section 12 and ActewAGL’s Service and Installation Rules.It is proposed that the infrastructure for the street lights will be installed in a shared trench with gasand telecommunications.ActewAGL has advised that a nearby substation on Getting Crescent has sufficient spare capacity tosupply power for the proposed street lights. A street light controller will be required for operation ofthe proposed street lights; the location of this infrastructure is yet to be determined by ActewAGL.8.10 Temporary traffic managementRefer drawings 110029/C1120 - 23In the development of the concept TTMs, careful consideration has been given to the connections toexisting roads and in particular intersection construction staging. This is so that the generalfunctionality is maintained and where possible the capacity of temporary roadways is maximised.8.11 Retaining walls and structuresConcrete retaining walls will be required within the park area to create terraces for the stormwaterdetention area and landscaping features. These structures will be mostly located at the southwesternend of the park area and adjacent to the swale.Concrete retaining walls will also be required in the public square/plaza between the end of Road 1-(C) and Constitution Avenue.Several different bridge structures will be installed as part of the landscape works to the park area. Acombination of small FRP and concrete bridges up to 5m long cross the swale and provide access toplay and exercise areas. A more substantial bridge approximately 30m long crosses over thestormwater detention area at the southern end of the park.November 2012 Cardno 77
