Construction of major public transport infrastructure, such as a light rail system, is governed by a number of conditions including hours of work, the management of noise, vibration and dust, and working together with communities on measures that will mitigate impacts.
Hours of work
Most light rail construction work is carried out during the day. Standard hours are between 7:00am to 7:00pm (or 7:00am to 6:00pm 'Eat Street') Monday to Friday, and 7:00am to 6:00pm Saturdays, Sundays and Public Holidays. There will be occasions where work will need to occur outside these hours (for example, at night) for safety or operational reasons, which can include:
- major road closures and work at critical intersections
- works considered excessively disruptive to business,
- residents and road users during standard hours
Businesses and residents will always be notified in advance when construction activities need to take place outside standard hours, unless it’s an emergency.
Notifying the community
Before any construction activity commences, letterbox notifications are distributed to any properties likely to be impacted by the works. When works are undertaken outside specified construction hours, nearby residents and businesses will be notified separately.
Noise, vibration and dust
While every effort will be made to mitigate noise impacts where possible, there will be a level of noise and vibration due to the range of activities and equipment used during light rail construction. Common sources include heavy machinery, trucks, pavement works, and excavation or earthworks that involve jackhammering or rock-breaking.
Construction activities can generate varying degrees of ground vibration as well as vibrations felt in adjacent buildings, depending on the types of equipment and methods used. Activities that may generate vibration include earthworks, site clearing and demolition, bulldozers and excavators, concrete breaking and removal, and ground compaction.
Dust impacts are closely monitored, with mitigation measures including barriers around construction sites, watering and covering of exposed areas, street sweeping and other dust minimisation techniques.
