Skanska Deploys Fully Electric Tandem Roller on Purple (D Line) Extension

Los Angeles | CA: Skanska, a leading construction and development firm, is piloting a zero-emissions electric compaction roller on its Los Angeles Purple (D Line) Extension Transit Project. The Wirtgen Group’s battery-powered Hamm HD 12e VV, a pre-production model, is one of only five of its kind in North America and is among the first all-electric compactors to be employed on an ongoing project in the United States.

The battery-powered electric compaction roller is designed to have the same capabilities as a conventional diesel compaction roller. Skanska is currently using the roller in the compaction of subgrade and crushed aggregates at the Fairfax station. The pilot will test the capability, durability, sustainability, and operator acceptance of the machinery on the active project."

The HD 12e VV, provided by Sunbelt Rentals, is the second fully electric piece of equipment piloted by Skanska on the Purple (D Line) Extension Transit Project.

“Skanska is proud to be among the first contractors to test the electric roller with Hamm. The pilot serves as an important steppingstone in the evolution of lower-emission construction practices while aligning with Skanska’s commitment to a more sustainable future,” said Mason Ford, director of sustainability and equipment services for Skanska USA Civil. “Through participation in pilots like these, Skanska will continue to have the opportunity to learn more about sustainable innovation and further the conversation around increased electrification on construction jobsites."
