The building works are expected to be completed around 2026, the 100th anniversary of Gaudi's death, although the likelihood of meeting this date is disputed. Computer modelling has been used for the detailed design of the intricate structure of supporting columns inside the basilica. See also catenary. CAD/CAM technology has been used to speed up the construction of the building; initially, the construction work was expected to last for several hundred years, based on building techniques available in the early 1900s. The construction work calls for many pieces of stone to be machined to unique shapes, each being subtly different from the next, and these pieces are now being machined accurately off-site, reducing the overall construction time.
