Trenching is required for utility installation. This includes laying water supply lines, sewer systems, electrical cables, telecommunication ducts, and gas lines. It is also necessary for Drainage Systems such as stormwater pipes, sanitary sewers, and subsurface drainage solutions like French Drains. In addition, to creating Footings and Foundation Trenches.

Utility Trenches are narrow and deep, designed to accommodate one or more types of utilities. Drainage trenches are sloped to allow water flow and often involve perforated pipes and gravel. Footing trenches are wider and shallower, used to form the base of a structure.

Trenching is dangerous and must be performed with strict attention to Worker Safety. The most critical hazard is Cave-Ins. To protect workers, several methods are employed, including sloping trench walls, shoring with support systems, and using Trench Boxes. Any trench deeper than Four Feet requires protective systems (Unless it is entirely made of stable rock). Trenches must be inspected daily and after weather events.

In sensitive areas where utilities are present, Hydro Vac trucks use pressurized water and vacuum systems to expose buried utilities without the risk of damaging utilities resulting from Digging Equipment use.

Trenching must be carefully planned and coordinated to avoid delays and conflicts. The process typically begins after site grading and before foundation work. Early coordination is required with utility companies for service connections and underground utility locates. The sequence of trenching work must align with other trades such as electricians, plumbers, and communication installers to prevent repeated digging. Poor coordination can lead to costly rework and scheduling delays.

Weather conditions can impact trenching, especially in wet or freezing environments that compromise trench stability or make excavation unsafe. Backfilling and compacting trenches must be scheduled in a timely manner to restore site access and prepare for subsequent construction activities, such as paving or pouring slabs.
