Swedish construction group Skanska booked an 18% increase in revenue to SEK 31.5bn (EUR 3.4bn) in its first quarter report for 2008. The rise in revenue from construction follows an earlier announcement that operating income for the group amounted to SEK 1.08bn. This figure included a gain of SEK 643mln on the sale of its 50% stake in the Ponte de Pedra hydropower plant in Brazil.
