| In a case study presented in the January 2002 issue of Facilities Design & Management magazine, two GSA buildings in St. Louis, Missouri (located only two blocks apart), were recently measured for a space validation study under SDI.
The Robert A. Young Federal Building, built in 1930, is an office complex that’s gone through its share of remodels and additions in its seven-decade history. After the survey, the building grew by 10,649 square feet (1% increase) to 1,008,138 square feet.
The Eagleton Courthouse, built in 1997, is a 35-story facility that houses the US Court of Appeals, District Court, Bankruptcy Court, Tax Court and other court-related agencies. Unlike the RAY Building, it has not had any remodels or additions, yet it was still a good candidate for spatial validation. After the survey, the building grew by 289,791 square feet (33% increase) to 1,156,369 square feet.
As mentioned previously, most spatial validation surveys find 3% to 4% growth in rentable square feet. The unusually large growth in the Eagleton Courthouse isn't as uncommon as one might think. The reclassification of spaces such as mechanical areas, electrical areas, atriums, hallways and joint-use areas are a few examples of spaces that often are overlooked in calculating rentable space.
Even the small 1% growth of the RAY Building is not insignificant when considering the income that may be generated by more than 10,000 square feet of rentable space.
