When construction takes place on a vacant lot, new utility lines will have to be installed to connect the property to essential services, such as power, internet, gas, and water. However, since working with these resources can present a variety of safety risks, general contractors must make sure they’re set up according to regulations. If you’re planning to develop land or start new construction, here’s what you can expect during underground utility line installation.

How Are Underground Utility Lines Installed?

1. Site Preparation  

Before any digging can occur, the general contractor or site manager must arrange to meet with a utility locator. If you don’t have one for your project, call 811 to be connected with a locator in your area.

These specialists will survey the site and mark all existing utility lines within the intended dig zone. This identification is important, as hitting an active utility line during construction may result in injury, outages, and fines. With this information, utility experts on the construction team will identify accessible connection points and map out the most efficient way to lay the lines.

2. Trenching

Next, excavation crews clear the site and dig modestly sized trenches where the intended utility lines have been mapped out. While these trenches should be deep enough to secure the lines away from the surface, they must remain shallow enough to allow for future access. If necessary, support structures—such as concrete walls—may be placed in the trenches to prevent the surrounding soil from collapsing.

3. Conduit Installation

Pipes are laid in the trenches to support gas, water, and sewage lines. Conduits—sturdy, protective tubes—are placed to house electrical lines.

These pathways are strategically arranged to ensure they’re placed at a safe distance. Once all pipes and conduits are secure, the trench is backfilled.

4. Cabling

Cables that support electric, internet, and phone connections are carefully routed through the entrenched conduits. After the connections are verified to be secure, the utility lines can be turned on.

5. Site Restoration

After all utility lines are made active, construction crews will work to restore or improve the site. In some cases, this may involve grading or installing topsoil. In other instances, roadways may be paved over the lines.
