ACE is headquartered in Columbia, MD, and works in Maryland, Washington, DC, and Northern Virginia. As a public works builder, we primarily work for cities, counties, and water authorities, and sometimes work for the state and federal government. Our projects contribute to the public good, providing critical improvements to our local water infrastructure. Whether it be a new wastewater treatment plant, a municipal facility, or emergency pipeline repairs, these projects are essential to the backbone of community. This naturally fits with our Building To Last cornerstone of “Building Community.”
