Impact for construction companies and residents

Periodic bridge maintenance in the mountain region aims to keep critical infrastructure in service for the connectivity of San José de Maipo, a territory where bridges concentrate local traffic and access to rural sectors. The 365-day term and the budget of $2,247,000,000 open a significant work front for construction companies registered in the Registro de Obras Mayores (Major Works Registry) with experience in earthworks, structural concrete, or pavements.

For residents, the process defines when and under what conditions the structures will be intervened, although effective execution will depend on the award and the start of works once the bidding deadline of November 3 has closed.
