Interior

• Flooring
  Design upgrades also feature the removal and replacement of carpet and furniture in the concourse hold rooms. This work will be done overnight between the last flight of the evening and first flight of the next day, requiring crews to remove only as much flooring as can be replaced in a single shift to maintain airport operations. Scheduled over three phases, these targeted improvements make a direct impact to the personal experience of travelers through DC.
• Drywalls
  One of the critical project challenges was the preservation of the integrity of historic murals and artifacts that resided within the museum. Mural salvage was an important component of this; however, the joint compound used to hold up the drywall from the original build contained asbestos behind them.

• Excavation
  Our roots trace back to 1906 when George Hyman founded a small excavating enterprise, the George Hyman Construction Company. Hyman was the first in Washington, DC, to use a steam shovel, shown here performing site excavation at the Smithsonian’s Freer Gallery of Art in the early 1900s.

General

• Carpentry
  An enhanced carpentry apprenticeship program to connect those entering this skilled trade with additional resources to ensure their success. Meet Maria Arevalo, a Clark Concrete carpenter apprentice on the WMATA Northern Bus Garage Reconstruction project, to learn more about the enhanced carpentry apprenticeship program and her experience. We are also excited to be launching a youth apprenticeship program for formwork carpentry in summer 2024.
• Masonry
  The retrofitted 19th-century unreinforced masonry structure now serves as a welcoming environment for the thousands of domestic and wildlife animals that come through its doors every year.
