The Challenge

Aging overhead infrastructure required replacing on Carscadden Drive in North York, along with three building vaults. Rebuilding and upgrading old infrastructure offers communities and neighbourhoods more reliability from the grid, with fewer power interruptions and less downtime because newer infrastructure runs more effectively and efficiently, and provides a safer environment for residents as well as hydro maintenance personnel.

DPM’s Role

Due to extensive knowledge of overhead, vaults, chamber/ductbank systems and general underground distribution, in addition to our past Toronto Hydro experience, DPM Energy offered Toronto Hydro the right expertise for the job.

DPM’s Responsibilities

These deliverables included the following services:

• field inspection

• scope review

• preparation of construction drawings

• supporting calculations

DPM’s Solution

We analyzed information, gathered off-field photos and notes, and from Toronto Hydro information:

• Field-checked all existing hydro infrastructure and made field decisions for the proposed infrastructure.

• Created designs that will allow the old system to remain LIVE while the new system is being installed.

• Made technical calculations to ensure safety for the contractor, residents and maintenance personnel.
