Douglas County officials are working to make roof repairs an engineer says were originally left out of the construction process more than 100 years ago when the Douglas County Courthouse was built.

Don McMican, a structural engineer and president of DGM Consultants P.A., said the deficiencies were discovered during recent repair work. The trouble spots are above the County Commission meeting room and the eastern stairwell.

He said the main problem is a strut at the southern roof of the building was never installed in 1902. The new strut is needed to take the pressure off one already in place.

If snow builds up on the roof, it could eventually cause support problems, McMican said. He said two other support trusses were not installed originally.

County staff members are seeking bids on the repairs, which are expected to cost $25,000 to $40,000.
