Open-cut construction to begin on 34th Avenue for new pipe installation
Open-cut construction will excavate 34th Avenue to install a new pipe using cut-and-cover methods; crews will backfill, restore the roadway and manage traffic impacts.
The project’s next phase will move from microtunneling to open-cut construction on 34th Avenue, introducing visible surface work within the public right-of-way. Crews will dig a trench, place the new main and backfill the excavation before restoring the street to its pre-construction condition. The change in technique is expected to alter the nature and visibility of construction impacts for residents and road users.
Open-cut method selected for Stage B on 34th Avenue
The contractor will use the cut-and-cover approach along the length of the planned alignment on 34th Avenue. Work will be confined to the public right-of-way and is intended to allow direct access to the pipe corridor for installation and inspection.
This stage contrasts with Stage A of the project, which used microtunneling to install pipeline below the surface with minimal disturbance. The shift to open-cut means excavation will be aboveground and require temporary changes to the roadway and adjacent curb areas.
How the cut-and-cover process will be carried out
Crews will first set up traffic control, signage and protective barriers to separate the work zone from pedestrians and vehicles. Excavators will dig a trench to the required depth and width for the new pipe, with spoil material staged for later backfilling.
Once the pipe is laid and connections are completed, contractors will backfill the trench in controlled lifts, compacting material to meet engineering specifications. Final surface restoration will replicate the pre-construction condition of the pavement, sidewalks and curbs where they are affected.
Why the project moved from microtunneling to open-cut
Microtunneling, used in Stage A, minimizes surface disruption by installing pipe through remote-driven tunnels beneath streets and utilities. Open-cut is typically chosen when direct trench access is feasible and allows faster placement of larger or specially configured pipe segments.
Project managers indicated the change reflects the conditions along 34th Avenue and the engineering needs for the new line. Open-cut can reduce specialized equipment needs and permit easier access for crews during installation and for future inspections.
Traffic management and community impacts on 34th Avenue
Residents and businesses along 34th Avenue should expect localized lane closures, temporary parking restrictions and short detours during daytime work periods. Access to driveways and properties will be maintained where possible, and crews will coordinate with affected occupants to minimize disruptions.
Construction noise, dust and construction vehicle movements are anticipated and will be managed under standard municipal requirements. The project team will deploy signage, flaggers and traffic control plans to guide motorists and cyclists safely around the work zones.
Safety, environmental safeguards and utility coordination
Contractors will implement sediment and erosion controls, dust suppression measures and routine site housekeeping to limit environmental impacts. Utility locates and shoring will be completed before excavation to protect underground services and maintain worker and public safety.
Inspection and testing protocols will follow engineering standards, including compaction verification and pressure testing of the installed pipe where applicable. Waste material will be handled according to local regulations and any landscaping or street furniture disturbed by work will be restored as part of the finish works.
Permits, communication and next steps for the corridor
The open-cut phase will proceed under the approvals and permits already secured for the overall project, and work will be staged to coordinate with other municipal programs in the area. Public notices, updates and contact information will be distributed to residents to inform them of specific schedules and temporary restrictions.
Project coordinators will monitor progress and adjust the work plan as needed to respond to site conditions and community feedback. Once pipe installation and backfilling are complete, crews will complete paving, concrete repairs and any final landscaping to return 34th Avenue to normal use.
Residents and road users are encouraged to consult posted notices and to follow traffic control directions while work is underway. The open-cut construction will be visible and active, but crews will restore the roadway to its pre-construction state once the new pipe is fully installed and tested.
