Calatrava's Chicago Spire is finally under construction

The construction of The Chicago Spire started in July 2007. Over the following months, 34 supporting caissons will be drilled 120 feet into bedrock below the site, providing the foundation for all subsequent construction. The caisson support system was pioneered in Chicago at the end of the nineteenth century and has been pivotal in creating the city's already impressive skyline. Case Foundation Company, who were engaged in June to commence works, are delighted with progress so far. This sub-ground phase of development will be completed by Q1 2008.

The next stage of development focuses on creating access ramps to and from Lake Shore Drive. The aim is to serve the needs of the site throughout construction, with a minimal impact on traffic flow in the city and the surrounding area. From that point forward, the focus will be on reaching first occupancy early in 2011.
