Last edited: 02-09-2017

CHALLENGES

  • Both wind farms were placed in Mapuche territory, native Araucanians.
  • Accesses to the wind farms were complicated.
  • There was an floofing area in Los Buenos Aires, that made the fundations works very hard.
  • Expediting procedures of the customer and some deadlines in the equipment deliveries made the schedule compliance difficult.
  • Three new subcontractors have been hired to work at the substation. More experienced companies were overflow, due to the high demand of the market.
  • Crane movements between platforms needed to be done with partial or total crane dismantling.

SOLUTIONS

  • GES worked together with the community. Sand and gravel were bought at the local quarry and a mapuche women cooperative was created for the services at the dining room.
  • It was necessary to build two bridges to access the site.
  • Water was pumped 24 hours a day to make the fundation works possible at the flooding area.
  • Equipment deadlines have been renegotiated with suppliers and air transport was used to shorten deadlines.
  • A very strenght coordination was necessary to work with subconstructure to ensure the quality of the work.
  • Road survey were continously done, always trying to reduce the number of hours for the crane movements.

RESULT

Succesfully completion of the wind farm without accidents and with satisfactory quality standards.
