Construction group Strabag has been awarded an additional contract valued at €800 million for a further construction section at the 530MW Alto Maipo hydropower complex in Chile. The deal means Strabag has been contracted for € 1.5 billion worth of work on the scheme.

In November 2012, Strabag was awarded the contract to build a part of complex, but difficult technical conditions and the withdrawal of a contractor led the client, AES Gener, to conclude a new construction agreement with Strabag S.p.A. of Chile on 19 February 2018. The agreement became fully effective at the end of May.

The new construction contract concerns 73km of tunnelling work on the Yeso/Volcán System, that had previously been the responsibility of the client or of third parties. The new total contract price is a lump sum that covers both the work that has already been rendered as well as all future work to be provided by Strabag S.p.A. on the basis of the construction agreement.
