Transporting materials to the tower sites and site preparation
The materials for construction needed for each tower are brought to site and distributed along the right-of-way where the towers will be built. Smaller poles are placed between the towers to support the transmission cables.
After completing site surveys, flagging and placing a call to BC One Call, the crews carefully remove the topsoil, and any necessary tree removal and brushing. Access roads are built so construction vehicles and equipment can travel to the site.
Building the foundations and anchors
Different types of foundations may be used to support the towers, depending on the soil type, depth of bedrock, and structure type. Excavation may be done with a mechanical excavator, hydrovac, auger, or hand digging.
Assembling the towers
Towers are generally built from the ground up. Line workers assemble the towers on the ground near the tower location - much like a giant, complicated 3D puzzle. This includes the use of heavy machinery. In areas that have soft ground composition, access mats (sometimes called rig mats) may be used to provide passage over the sensitive ground. Access mats provide structural support for equipment by dispersing weight and providing a solid base.
Raising the towers and poles
Tower sections are either assembled all in one piece, or in multiple pieces that are connected after they are raised. Telescopic cranes or helicopters are used to raise the tower sections from the ground, and bolt them together to complete assembly.
Poles are used to support cables between transmission towers and to maintain the tension of the cable. Framing and hardwire installation will be completed before the poles are installed, then lifted and set into place.
