Portland, OR -

The city of Portland's office tower leaks from the roof, windows, siding and grout. Officials warn a major earthquake could ruin it. Workers complain about its sloping floors, small windows and lack of natural light.

When built in the early 1980s, The Portland Building next to City Hall drew attention for its post-modern design. It's also known for its "Portlandia" statue, and it's on the National Register of Historic Places. But complaints have been numerous, and major repairs have been put off.

The Oregonian reported Friday that a new city estimate puts the cost of fixing it at $95 million, and the cost of rebuilding at $110 million to $140 million.

A spokesman says Mayor Charlie Hales has unanswered questions about the building and wants to see more alternatives.
