Arches, Vaults and Domes (AVD) have been used since millennia worldwide. With the developments of 20th century industrial building materials and methods such as steel and reinforced cement concrete (RCC), the knowledge of masonry vaulting has been all but lost. The Auroville Earth Institute attempts to revive these forms, techniques and craftsmen skills with the following aims:
To increase global awareness of the low-cost, low-carbon possibilities of masonry flooring and roofing.
To research and develop constructive techniques with the aim to integrate 21st century technologies with age-old building techniques, such as those developed in ancient Egypt or medieval Europe.
To design large-span structures, with structurally optimized thickness and integrated construction methods.
