Moisture Majorly Responsible For Deterioration of Wisconsin State Capitol Dome

Nearly 200 feet up, inside the outer dome plaster is peeling away from the bricks that were laid in place almost more than 100 years ago when the Capitol was built. Architects have been assigned the task of restoration and the work is going on full swing.

As per officials the plaster of the dome is deteriorating due to a moisture problem caused by humidity changes, leaking water and non-breathable oil-based paint. They said the problem has been known for years, but the work to fix it up has started now.

Laura Davis, the lead architect on the project said in a statement that the task is merely to repair plaster but the repair has to be made 200 feet in the air and in the most prominent building of the state. Davis, with Isthmus Architecture in Madison, has been working on Capitol projects since 1992.

The repairs mark the end of a series of rehabilitation work that began at the Capitol in the 1990s, costing more than $141 million. Although their work will be mostly hidden from the view, the plaster repair work is still exciting.

While inside the narrow inner balcony not accessible to the public, just below the ‘Resources of Wisconsin’ mural inside the interior of the Capitol’s dome, she said, “It’s so difficult to get up here. It’s just a fun project”.

Access to the rotunda on the ground and first floors of the Capitol was closed for ubloic after the workers put down a plywood floor to protect the marble in case anything is dropped during the plaster repair work.

“It’s pretty much a plaster repair project but it’s 200 feet in the air in the most prominent building in the state,” said Laura Davis, the lead architect on the project. Davis, with Isthmus Architecture in Madison, has been working on Capitol projects since 1992.
