Industry Specific Challenge
Staging for Linear Construction of Power Lines

Unique Installation Equipment
Almita’s fleet of track based excavators are perfectly equipped to move down a power line from installation site to installation site. Our depth of powerline construction experience will allow us to help address your project’s specific staging and right of way access needs.

Uplift Resistance

Helical Piles
In addition to providing excellent compression loading, the helix on Almita’s piles provides superior uplift resistance compared to other foundation solutions. This uplift resistance is critically important to all types of transmission towers.

Varying Geotechnical Conditions

Custom Engineering and Field Experience
Almita’s team of Engineers has a broad depth of experience dealing with the changing geotechnical conditions that are encountered over the length of a powerline construction project. Our project management team works with you and our engineers to quickly address any challenges encountered in the field, and develop solutions to ensure that your project doesn’t encounter any delays.

Case Study
| New Powerline

BC Hydro, Dawson Creek, BC


BC Hydro faced the challenge of installing 240 tower foundations over 73 linear kilometres of diverse and consistently difficult terrain from Dawson Creek to Chetwynd. These towers consisted of 170 monopoles and 70 lattice towers, all designed to accommodate differing geotechnical conditions over the length of the project.


The Almita engineering team worked closely with the BC Hyrdro engineering team to develop foundations that could meet the changing geotechnical conditions as well as the different tower types selected for the project. We partnered with Deramore Construction to address access issues to foundation sites and ran 24 hour shifting to address the schedule constraints of the winter construction season. To withstand the harsh environmental conditions while meeting the unique foundation needs of each tower type, Almita employed separate helical pile arrangements. Under each lattice tower base is a group of helical piles tied together with a common steel cap. Under each monopole tower is a group of helical piles with grillage beam connections and adjustable frames for each tower type.


Working within a tight timeline Almita produced 3045 helical piles and 2100 extensions for the lead piles. Foundation types varied from 4 piles to 48 piles per structure. Pile types varied from 25 ft. pile leads with double helixes up to 70 ft. including pile leads and 2 extensions with up to 7 helixes in total. In addition to pile installation, Almita was also responsible for cap welding, grillage installation, survey, and pre-drill. The final cost of this project, accounting for design, fabrication, installation, and project management totalled $20.5 million.
