Extremely Large Telescope (ELT) – Cerro Armazones, Atacama Desert, northern Chile
PROJECT
The Extremely Large Telescope (ELT) is the world’s largest astronomical observatory, consisting of a primary mirror with a 39 m diameter. The optical system will be supported by a 62 m high metallic structure with a 71 m diameter, placed on a reinforced concrete foundation, and protected by a rotating metal dome 80 m high and with a 92 m diameter. Two sets of laterally-opening doors form the observing slit, providing needed protection to the telescope in inclement weather and during the day. ELT is currently under construction in Cerro Armazones in the Atacama Desert of northern Chile, at 3000 mAOD.
CHALLEGES
The building has a complicated structure made of steel and reinforced concrete and contains numerous pieces of machinery that need fire protection. Due to the complexity of the building, determining appropriate fire approach and regulations while preserving its architecture was challenging.
SOLUTIONS
IDF played a crucial role in all aspects of fire engineering. To ensure fire safety for the building, IDF went beyond the standard regulations and pushed the design approach limits by seeking consultation from local and international authorities. IDF was appointed for Fire Strategy Design in compliance with international and Chilean regulations of reference, performance-based analysis of people and smoke evacuation models, passive fire protection solutions in synergy with Cimolai, to active fire protection systems design.
