Environmental management

The Ipswich Motorway Upgrade Rocklea to Darra — Stage 1 project recognises the importance of minimising construction impacts on the environment and is committed to achieving positive environmental outcomes.

We will implement a range of measures to protect and preserve the natural environment including sensitive areas across the Oxley Creek floodplain in accordance with legislative requirements. We consult with relevant Queensland Government agencies to carefully manage construction activities within and near the watercourse.

Protecting waterways during construction

Worker conducting water testingLocal waterways such as Oxley Creek and Little Doris Creek flow through the project corridor. These watercourses will be protected via a range of measures including:

  • temporary erosion and sediment controls (such as sediment retention basins, rock dams and sediment fences) will be used where necessary to control and treat water leaving the site
  • mandatory testing of treated water before it is released from the site
  • concrete washout areas to ensure construction debris from machinery and equipment does not spill into local waterways
  • weekly water testing and monitoring of waterways located within the project corridor to ensure
  • construction activities are not impacting on the water quality of the local catchment
  • third-party audits of erosion and sediment control measures.

Before works start on each site, the we will carefully consider the potential impacts of construction activities, with the aim of minimising such impacts where possible.

Managing air quality

Construction activities occurring across the project corridor are likely to have some impact on air quality. Excavation, compaction and vehicle movements on unsealed tracks also have the potential to create dust, resulting in impacts to air quality within and near the construction site. Some of the ways we will manage air quality include:

  • daily site inspections during days of operation and periodic audits of all sites
  • spraying water on unsealed (dirt and gravel) roads and adding dust suppressants or ground treatments to bind soil together and minimise dust in the air
  • covering loads on trucks when they exit work sites
  • watering stockpiles to keep exposed material damp
  • setting low speed limits on unsealed roads used within the project corridor
  • regular briefings with project staff to ensure they work responsibly to reduce the risks of dust impacts on the local community.

We will operate under the guidelines set by the National Environment Protection (Ambient Air Quality) Measure 1998 to determine air quality conditions.

Protecting animals during construction

Animal specialists, known as fauna spotter-catchers, locate and identify any wildlife habitat within the project corridor prior to construction works. They are specifically trained to handle animals and relocate them if necessary. They carry out site inspections before any clearing works take place and are available during such activities in case any fauna requires handling or relocation.

Managing culturally significant areas

Historic bridge remains are located within Oxley Creek and are believed to be the piers of the first wooden bridge over Oxley Creek. The project has been purposefully designed to avoid impacting on these bridge remains.

All staff and subcontractors will receive a Cultural Heritage Induction prior to commencing ground disturbance works. The induction includes management procedures for working in proximity to the historic timber bridge remains and a FIND, STOP, NOTIFY procedure in the event of an unexpected heritage find. If a find is made, the we will isolate the find before notifying the appropriate authority or group.

Noise during construction

We are committed to reducing noise impacts on the local community, however some noise disturbances will be unavoidable during the upgrade works.

Majority of works will be carried out during the day between 7am and 5pm, Monday to Saturday. Night works will also be required and typically carried out Sunday to Thursday nights between 8pm and 5am. Conducting night works when traffic flows are at their lowest helps minimise impacts on motorists and provides a safe work area for construction crews.

We will ensure local residents will be notified before any noisy night works are scheduled.
