Images of the project


PT Vale Indonesia Tbk operates two dry ore storage at its Sorowako Process Plant – Dry Ore Storage 1 (DOS #1) and Dry Ore Storage 2 (DOS #2). Both facilities were built at the time of plant set-up in the 1970s. They consist of glue-laminated timber arch structures with timber purlins, clad with profile metal sheeting.

The DOS #2 has suffered a deterioration of its structure caused by environmental and operational activities.
