Residents in the Southeast and Central-East parts of Edmonton, as well as those in Strathcona County adjacent to Southeast/East portions of Edmonton, might hear what sounds like a shotgun and looks like a small explosion over the coming weeks.
Starting on October 7, 2013 and continuing for the next few weeks, the Heartland Transmission Project will be using implosive connectors to fuse portions of transmission line wire together. These connections create a flash and sound like a small explosion, similar to that of a gunshot. As a warning before these connections, three horn blasts will occur. We expect an average of three large boom sounds to be produced per day - during typical working hours only.
The use of these types of connectors provide the most reliable connection for transmission line.
We are notifying landowners and business owners in the vicinity of the construction work. Below is a link to maps regarding the location of the Heartland structures in question. Below is our anticipated timelines for completion of implodes at each structure.
- Structure 40 - Complete
- Structure 65 and 67 - Late November
- Structure 29 and 37 - Late November
- Structure 19 and 21 - Early December
- Structure 174 and 195 - Late November
- Structure 34 and 35 - Late November
Maps T2, T3, T4 and T6 contain the structure sites where implodes will be used.
To warn nearby residents of upcoming explosive blast, three loud horn blasts will occur. A small explosion and a quick flash will follow shortly thereafter. Blasts can be heard up to three miles away.
Don't be alarmed if you see or hear this work being done. Local police and fire departments have been notified and will monitor the work closely.
Construction of the Heartland Transmission Project
Over the coming months the Heartland Transmission Project team will be using a helicopter to assist with construction. The helicopter will be used to string rope lines between each tower and install equipment at the top of each tower.
The use of a helicopter reduces the amount of construction traffic and environmental impacts along the transmission line right-of-way. Using a helicopter to install equipment at the top of each tower is significantly faster than other construction techniques.
The Heartland Project Team will be using one helicopter at a time between the hours of 7 AM and 7PM.
Our priority is the safety of our employees, contractors and the public throughout the construction process. All work areas will be safe and secured and the Project Team asks that the public keep a safe distance away from the construction sites.
Starting late May, 2013, we anticipate the first monopole tower to be installed. Monopoles will be installed over a 9.5 km stretch within the TUC, from approximately Hwy 14 to Baseline Road.
