Particle Accelerator / The Weizmann Institute of Science, Rehovot
A complex engineering project that demanded utmost precision and constant calculations to find the most suitable cement mixtures. Difficulties arose as early as the digging the foundations, when the combination of sandy and rocky soil necessitated the use of special diamond drills. Once foundation were laid, poles had to be cast with great precision 25 meters into the ground, in order to support the building and the accelerator itself, which is made of steel and weighs hundreds of tons. After the lower shell was poured to a height of 12 meters, the accelerator was assembled while the upper shell was being built. The exterior walls are two meters thick, and the building is 65 meters tall.
