DTMR QLD Smart LED Road Lighting Upgrade
Department of Transport and Main Roads (DTMR) are undertaking a seven-year project, which began in the 2018/19 financial year. The project involves state-wide replacement of legacy road lighting HID luminaires with equivalent LED luminaires, to be operated using a smart lighting Control & Monitoring System (CMS).
The project aims to lower DTMR’s energy consumption and reduce ongoing maintenance costs in addition to identifying lighting deficiencies and providing rectification utilising existing hardware, if possible.

Our Project Mission
Harrison Infrastructure Group (HIG) were engaged for multiple packages of works including packages 2, 7, 13 & 14 across all DTMR regions. The project scope called for the delivery of design drawings and documentation for LED upgrade of the nominated sites in accordance with DTMR requirements and AS1158.
Under this project, to date, HIG have designed over 4,500 luminaires.
Our Approach
The design analysed the existing lighting capacity and identified several non-conformances that needed to be addressed. HIG was able to determine a number of suitable amendments to the lighting scheme.
The staged milestone deliverables provided for DTMR’s desired luminaire models to be tested and presented in the early stages of the project. As it was seen that the desired designs did not conform to the lighting standards more powerful luminaires were modelled and subsequently justified in the design report showing that the energy output was less than the existing.
The design team was able to identify multiple instances where the existing lighting configuration was unable to be amended to meet design standards. Additionally, HIG determined that due to the proximity of some of the sites to aerodromes/airports the department should advise the airport of the proposed modifications prior to undertaking works (as per manual of standards part 139 – section 9.21.).
Photometric data was also assessed to confirm compliance to the manual of standards part 139 with relation to light above the horizon within runway approach/departure locations.
HIG excelled with analysis of the existing lighting and provided expert knowledge advice that detailed the existing non-conformances that existed that would be impacted (likely resulting in the relocation of multiple lighting poles too close to overhead powerlines) by stakeholders such as Energex, if the department progressed with their request for lighting changes.
