Fall 2002 is the expected completion date of Colonnades' 11-story, 2,100 space parking garage that is being built at an estimated hard construction cost of $10,000 per space or $21 million, area construction industry estimators tell GlobeSt.com on condition of anonymity.

The office building will be constructed atop the parking deck. When completed, the garage and office building will have a total 21 levels.

Colonnades officials couldn't be reached at GlobeSt.com's publication deadline to learn plans for the new office space. But area brokers who have been following the developer's progress tell GlobeSt.com the developer won't break ground on the new office building until an anchor is found.
