Construction crews are preparing to replace the Oklahoma Capitol's copper roof, which officials consider to be the biggest unexpected expense so far in the building's years-long restoration project.
The Oklahoman reports that replacing the 45,000 square feet of copper will cost the state $9.3 million. Project manager Trait Thompson says he doesn't plan to ask lawmakers for more money because the restoration plan has built-in funds for unforeseen expenses.
Thompson says the copper roof is "what was originally on the building, and it will also be a very long-lasting roof."
Construction workers are restoring both the exterior and interior of the century-old building. Exterior improvements are expected to be finished early next year. Interior construction is expected to be complete by the end of 2022.
