About Construction

January Lookahead

Installation of a rock causeway

  • The majority of work for January is focused on building the temporary rock causeway, which is the first step in providing crews access to start building the permanent bridge.
  • Constructing the rock causeway will be done within the confines of a turbidity protection fence which was previously installed. The protection fence acts as a barrier that excludes wildlife from the construction activity and is part of our commitment to protect the Cataraqui River. The turbidity curtain will also continue to be tested with a monitoring system, ensuring its effectiveness.

Eco-passages

  •  Five eco-passages will be built at certain points along the rock causeway. 
  • The eco-passages will allow for the safe and active passage of turtles and other wildlife species. These wildlife crossings will allow turtles and other wildlife to move up and down the Cataraqui River across the worksite.

Extended work hours

  • The temporary rock causeway is expected to take roughly 10-12 months to complete. As part of this phase of the project we anticipate needing to work extended hours, Monday through Saturday from 7 a.m. to 10 p.m.
  • To understand the effect of the extended work hours, the team undertook a night time construction noise impact assessment to determine potential impacts to nearby residential areas. The results of that study indicated noise levels will be within acceptable levels as per provincial guidelines.

Noise mitigation

  • To help with noise levels from construction activities, we have implemented several noise mitigation measures, including:
  1. Permanent noise fences on the east and west shores. Permanent noise fences were designed with higher acoustic attenuation quality than temporary construction barriers. This means a greater reduction in noise to surrounding residents throughout construction. A noise fence has been installed on the west shore and crews are now working to install the east shore noise fence.

  2. Use of quieter back-up alarms on certain equipment and trucks. Equipment will be equipped with broadband back-up alarms that don’t project sound as far as regular back-up alarms that traditionally have the 'beep' 'beep' noise. The broadband back-up alarm will diminish the back-up noise level significantly.

  3.  
  4. Strict compliance for dump trucks to avoid slamming tailgates or slamming the back of the truck when offloading rocks.

  5. Installation of noise monitoring equipment to monitor noise levels throughout off-hour construction
