Brazil is finalizing construction at its Foz do Chapec� hydroelectric plant. The last phase, a rockfill dam, was completed last April. The project used asphalt instead of clay as the main component of the sealing nucleus—a first in Brazil. The choice of this technique resulted from a number of advantages the contractors and owners of the project researched in Europe.

The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
