According to American School & University's 34th annual Official Education Construction Report, spending on construction by the nation's school districts and colleges slowed in 2007, representing the fourth consecutive year total expenditures dropped from the year before and setting a low point in spending so far this decade. A difficult economy and rapidly rising costs took their toll as many education institutions trimmed or postponed planned projects. Total spending on new, addition and modernization construction by school districts and higher-education institutions dropped to $32.9 billion from $36.6 billion in 2006. While total spending slowed, the amount K-12 institutions and colleges allocated to new buildings increased, reflecting the pressure to continue constructing new spaces to keep up with enrollment growth. School district spending on new construction increased to $14.7 billion in 2007 from $13.7 billion the year before, and college spending on new construction jumped to $7.3 billion from $5.3 billion in 2006. Education construction data--detailing spending by type of institution; projected spending through 2010; per-square-foot and per-student costs; and much more--are presented. New data on the impact of green and security on education construction is also included.
