The Typical Stages of Construction Include:
Construction of a new substation requires a large amount of materials, equipment and labour. You may hear or notice some construction activities depending on your proximity to the substation site.
Install access roads
Access roads may be required so that trucks can deliver materials and workers to the construction site. Vegetation is removed as needed. Access roads remain after construction is complete so workers can access the site for maintenance.
The ground at the site is prepared for the substation foundation. This includes leveling the soil, laying down insulating gravel and digging drainage areas.
Foundation and construction materials, including steel and gravel, are delivered to the work site. Construction equipment such as backhoes, semitrailers, moving equipment, concrete haulers and cranes may also be brought onsite. If required we will use a storage yard to store materials and equipment.
Structural foundation work
Concrete foundations for the substation equipment are constructed.
Major equipment installation
Assembled substation equipment is delivered to the site and installed using cranes and manual labour. Some minor equipment may be assembled at the substation site.
During and after construction, we will perform cleanup and reclamation of the surrounding area. More insulating gravel is laid down over the site.
Quality and safety inspections are completed and the new transmission line is energized and connected to Alberta’s electrical system.
