Insights

Strategic Acquisition Advantage The acquisition of Down Under Construction by Hylan Group in 2018 positions DUC as a valuable regional player with increased resources and expertise. This expansion enhances its capacity to undertake larger, more complex projects for federal, utility, and land development clients, offering a growth opportunity for vendors providing advanced trenchless technologies and integrated project solutions.

Diversified Client Base DUC's broad client portfolio, including federal agencies, land developers, utilities, and electrical contractors, creates multiple avenues for partnership and service offerings. Suppliers of specialized construction materials, engineering services, or environmental compliance solutions can tailor targeted outreach to expand collaborations across these sectors.

Industry Leadership & Innovation As a pioneer in directional drilling and trenchless construction within the Mid-Atlantic, DUC’s reputation for high-quality, efficient project delivery presents opportunities for vendors providing cutting-edge trenchless equipment, advanced engineering software, or innovative construction materials that align with industry best practices.

Growing Market Demand The expansion of trenchless technology beyond telecommunications into other infrastructure sectors suggests increasing industry demand. Companies offering complementary services such as design, permitting, or restoration services can find potential new projects by aligning with DUC’s comprehensive service model for large-scale underground construction.

Digital & Tech Adoption DUC utilises various digital tools and platforms indicating a willingness to integrate technology into its operations. Technology vendors providing construction management software, project tracking solutions, or innovative digital construction aids could position themselves as key partners to streamline DUC’s project workflows and enhance productivity.

Down Under Construction (DUC), a Hylan Company, was founded by Daryl Dunbar in 1993 and is headquartered in Sterling, Virginia. At the time, trenchless construction was in its infancy, and DUC began fostering the relationships the company still maintains today. Although the industry segments that DUC serves have grown, and the services offered diversified, the company has always held its client relationships and the quality of work performed paramount. 

Today, DUC serves the Federal Government, Land Developers, Utilities, and large Electrical Contractors. Our highly diversified client base demands multiple capabilities: Design, Engineering, and Permitting are all in-house DUC professional services that result in greater speed to market with higher quality production.

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 an array of services including conceptual design/survey, trenching, boring, cable placement, duct bank construction, engineering, permitting, splicing, and restoration of landscaping, concrete and asphalt.
