Skanska pilots electric tandem roller on Purple Line Extension project in Los Angeles

Construction giant Skanska is piloting an electric compaction roller (a piece of heavy equipment analogous to what a previous generation called a “steamroller”) on its Los Angeles Purple (D Line) Extension Transit Project.

The Wirtgen Group’s battery-powered HAMM HD 12e VV is designed to have the same capabilities as a conventional diesel compaction roller. Skanska’s unit is one of five pre-production models currently being tested in North America.

Skanska is using the roller for 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.

The HD 12e VV, which was provided by Sunbelt Rentals, is the second fully electric piece of equipment piloted by Skanska on this project. In February, Skanska completed a 90-day pilot program using the Volvo EC230 Electric excavator.

“The HAMM HD 12e VV pilot serves as an important stepping stone in the evolution of lower-emission construction practices,” said Mason Ford, Director of Sustainability and Equipment Services for Skanska USA Civil. “Through participation in pilots like these, we have the opportunity to learn how we can further advance sustainable innovation and the electrification of equipment on construction job sites.”
