Installation of an acoustic sound barrier fence on behalf of the City of Ottawa along the O-Train Line providing a noise barrier between the railway and residential housing. The fence was installed to the following specifications:
- 280 metres long;
- 3 metres in height;
- 460 - 610mm diameter footings; and
- 3 – 5 metre deep footings.
Footings dug using Hydro-Vac due to the close proximity of a private gas line.
Installation and removal of a hoarding fence between the railway and work area overnight while trains were inactive.
Removed existing pedestrian crossing, installed new fence and completed associated landscaping.
Removal and disposal of dead vegetation and any vegetation in the direct path of the wall.
Extensive safety control measures implemented and maintained throughout the duration of the project due to the close proximity to an active railway including working with a Flag Person during daytime work.
Landscaping, including grading and seeding, as well as tree planting was conducted.
