After selecting underground drop cable routes and locating other underground utilities, which burial method is most common in new construction areas?

• A. Trenching with open cut excavation
• B. Cable plowing
• C. Boring by horizontal directional drill
• D. Pulling the drop cable through a conduit

Answer: (B)

The method for burying a drop cable in new construction after routes are chosen and utilities located is cable plowing. This technique digs a narrow trench and lays the cable in the soil in a single pass as the plow moves along the route. It allows fast installation with very little surface disruption, which is ideal in new developments where lots are being prepared and restored work should be minimized. The burial depth is controlled and consistent, and the backfill is compacted as the plow passes, reducing restoration time and traffic impact. Open cut trenching, while traditional, is more disruptive and costly in a new development because it involves wider excavation and more surface disturbance. Horizontal directional drilling is used when you need to cross obstacles or minimize surface impact at specific points, but for long, straight runs typical of new subdivisions, plowing is more efficient. Pulling through a pre-installed conduit requires that conduit network already exists, which isn’t always the case in new areas. Cable plowing balances speed, cost, and reduced disturbance, making it the most common choice in many new construction projects.
