Acquired by Hylan in 2018, DUC serves the federal government, land developers, utilities, and large electrical contractors. Design, engineering, and permitting are all in-house DUC professional services that result in greater speed to market with higher quality production. DUC leads the market in trenchless and trench-based construction and installation of all types and technologies. DUC is considered one of the Mid-Atlantic region’s principal pioneers in the directional drilling and underground construction industry. As trenchless installations became the preferred method of construction for industries outside the telecommunications sector, DUC grew exponentially to meet the demands of its increasing customer base. DUC started operations as a general contractor in the directional drilling field, and has now matured into a turnkey prime contractor offering a vast array of services including conceptual design/survey, trenching, boring, cable placement, duct bank construction, engineering, permitting, splicing, and restoration of landscaping, concrete and asphalt.
