First reported in the Chicago Tribune, and today in the Wall Street Journal, officials at a group of union pension funds are vetting a plan to lend $170 million to restart construction on the stalled Chicago Spire. Designed by Santiago Calatrava, the 150 story residential tower would be the tallest building in the US. The Journal piece points out that with a drastic drop off in condo construction downtown predicted for 2010 and 2011, the completion of the Spire could actually come at a time when there is pent up demand for housing. Blair Kamin previously pointed out that unions have made similar loans in previous downturns, notably providing loans for the construction of Marina City. According to the Journal, Chicago's failure to win the 2016 Olympics may have been the key to giving the Spire new life. The pensions had previously been looking to lend funds for the construction of the planned Olympic Village.
