State officials released the price tag for the doors Wednesday in response to media inquiries more than a week ago. They had first said the cost could not be itemized.
Capitol architect J. Richard Alsop III says materials and fabrication made up $535,808 of the cost and installation and engineering make up the rest.
Alsop says the doors give the building a “desired and appropriate historical fabric.” A spokesman for House Speaker Michael Madigan explained the cost by noting that the building is a national landmark.
The $50 million project is being paid for with construction bonds. It includes replacement of heating and air-conditioning and bringing the building up to current safety codes.
