Giving the old Fairfax County courthouse a new face is going to cost almost twice what the county anticipated.

County officials will tell the Fairfax Board of Supervisors today that estimates on rehabilitating the facility, which houses the Juvenile and Domestic Relations District Court, will be about $5.9 million, compared to the original $3.3 million estimate.

The reasons for the higher estimates are expected to be discussed at the supervisors meeting, at which the board will be asked to approve the changes.

The county staff has also recommended that the design fee be increased from $468,000 to $679,000, and that the length of the contract be increased from 36 months to 69 months.

More than $79,000 of the design fee has already been paid to the architects.

Since the county's General District and Circuit courts moved into a modern new courthouse last year, the county has wrestled over the fate of the old structure, a beautiful but dilapidated building that leaked so badly during storms that buckets had to be placed in the hallways.

The county considered putting some agencies unrelated to the court system in the vacated space in the old courthouse, some portions of which are 183 years old, but eventually decided against that proposal. It does, however, plan to consolidate many of the administrative offices for the parole department and the juvenile court system in the building.

Those offices are currently scattered around the county in rented space.
