Project Overview :
Isaac Regional Council (Council) engaged JJR to undertake roads and stormwater design on Golden Mile Road near Dysart. The main objective was to upgrade the existing low-level floodway crossing and provide a flood resilient sustainable structure to allow safe traffic movement.
JJR Involvement :
JJR’s expert engineers prepared Final Design drawings for roads and stormwater, which included:
• Engineering survey;
• Site inspections to determine the level of investigation and testing;
- Geotechnical/Subsurface assessment;
- Desktop assessment to understand low-level floodway and catchment properties;
- Hydrology and Hydraulic Analysis; and
- Environmental scoping report.
Design work was developed in accordance with the following relevant standards and/or guidelines:
- Capricorn Municipal Development Guidelines (CMDG);
- Queensland Urban Drainage Manual (QUDM);
- Austroads – Guide to Road Design;
- Austroads – Guide to Pavement Technology;
- Queensland Transport & Main Roads (QTMR) – Pavement Design Manual & MRTS’s (latest edition);
- QTMR – Standard Specifications Roads;
- QTMR – MUTCD Manual of Uniform Traffic Control Devices;
- AS 1289 – Methods of soil testing for engineering purposes; and
- Institution of Engineers – Australian Rainfall and Runoff (ARR) –State Planning Policy 1/03 – Mitigating the Adverse Impacts of Flood, Bushfire and Landslide.
JJR further produced a Technical Memorandum with different design options and associated high-level cost estimate and bill of quantities for opportunities identified.
JJR then prepared the final detailed design for the preferred option.
