Repairs to the Capitol's exterior windows will be performed April 1, 2013 through late September 2013. The repairs are focused on the exterior side of the windows and some minor work on the interior side will take place during non-operational hours to avoid disruptions to the space occupants. A scaffold system will be used to reach each window and perform the repairs. Once the repairs to a block of windows have been completed, the scaffold towers will be relocated to the next set of windows requiring a similar access to complete the work.
