Underground Dry Utilities Across Washington DC, Maryland, and Virginia

What substation work does Anchor perform? Anchor provides the civil and underground infrastructure required to support substation construction, expansion, and rehabilitation. Our capabilities include site preparation, concrete foundations and equipment pads, underground duct banks and conduit systems, grounding grid installation, and structural support for switchgear, transformers, and other critical equipment.

As substations serve as essential links between transmission and distribution systems, we understand the importance of proper sequencing and coordination. Anchor works closely with the utility, electrical contractors, and other project stakeholders to coordinate the civil scope and deliver safe, reliable, and constructible substation infrastructure.

What is a duct bank? A duct bank is a group of conduits encased in concrete and buried below grade.

Anchor constructs concrete-encased underground duct bank systems that provide protected pathways for electrical and communications cables. Designed for long-term reliability and accessibility, these systems allow cables to be installed, maintained, replaced, or expanded without repeatedly excavating the utility corridor.

What communications infrastructure does Anchor install? Anchor installs and maintains the underground infrastructure that supports telecommunications, cable television, and fiber optic networks throughout the region. Our capabilities include duct banks and conduit systems, handholes, manholes and vaults, and associated cabling infrastructure that provides protected and accessible pathways for critical communications networks.

By building and maintaining this essential infrastructure, we help provide the reliable connectivity that links individuals, businesses, institutions, and communities and supports the region’s growing communications needs.

What is the difference between a conduit and a duct bank? A conduit is a single protective pathway for electrical or communications cables, while a duct bank consists of multiple conduits grouped together and typically encased in concrete. Conduit is generally used for individual runs and service connections, whereas duct banks are used for larger underground utility systems requiring multiple pathways and long-term protection.

Anchor installs conduit systems that protect electrical and communications cables from damage and environmental exposure, keeping them safe to operate and maintain.

What is an underground utility vault? An underground utility vault is a below-grade structure designed to house and provide access to electrical or communications equipment, cables, and connections. Vaults may be cast in place or installed as precast structures and provide a protected, accessible environment for inspection, maintenance, repairs, and system upgrades.

Anchor constructs cast-in-place and installs precast underground utility vaults that support critical electrical and communications infrastructure, helping protect equipment and maintain safe, reliable access throughout the life of the system.

What is the purpose of a utility manhole? A utility manhole is an underground access structure that allows crews to safely reach electrical or communications infrastructure for cable installation and pulling, splicing, inspection, maintenance, and repairs without the need for extensive excavation.

Anchor installs and maintains underground utility manholes that provide safe, reliable access to critical infrastructure throughout its service life, supporting efficient maintenance, repairs, and future system upgrades.

What are utility foundations and pads? Utility foundations and equipment pads are engineered concrete structures that provide stable, durable support for electrical and communications equipment. Concrete pads typically provide level mounting surfaces for above-ground equipment such as transformers, switchgear, cabinets, and pedestals, while foundations are designed to support larger or heavier equipment and are constructed to meet specific structural and equipment requirements.

Anchor constructs cast-in-place concrete foundations and equipment pads for dry utility installations, with an emphasis on accurate layout, proper elevation, and precise placement to support efficient equipment installation and long-term structural stability.

What is a pole foundation? A pole foundation is a below-grade concrete structure designed to anchor and support utility, lighting, or signal poles. It transfers structural and environmental loads into the surrounding ground, helping keep the pole properly aligned, stable, and secure throughout its service life.

Anchor constructs cast-in-place concrete pole foundations and bases for utility and communications infrastructure, with careful attention to layout, depth, elevation, anchor bolt placement, and alignment to support proper installation and long-term structural performance.

What does mainline and service work cover? Mainline work involves the primary underground utility infrastructure that carries electrical power or communications along a roadway, utility corridor, or development. Service work connects that mainline infrastructure to individual buildings, facilities, or sites. Supporting structures, including manholes, vaults, handholes, and pull boxes, provide access points for cable installation, connections, maintenance, and repairs.

Anchor installs and maintains mainline systems, service connections, and associated underground structures for electrical and communications utilities, providing reliable infrastructure from the primary utility network to the customer connection point.

What is a taphole? A taphole is an opening created in an existing underground utility structure, such as a manhole or vault, to accommodate a new conduit or service connection. This allows new infrastructure to connect to an existing system without requiring the structure to be replaced or completely rebuilt.

Anchor performs precise taphole installations for underground electrical and communications infrastructure, helping create properly located and sized connection points for new conduits, service connections, and system expansions while maintaining the integrity of the existing structure.
