Utility Locating

Quality Levels of Service

Locates each utility by actually exposing every line horizontally and vertically. This is the most accurate utility locating method however it is very labor intensive, time-consuming and expensive.

Uses a) record drawings, b) visible features above ground, and c) technologies to identify underground structures.

Involves surveying utility features that are visible above ground and correlating them with existing utility records.

Relies solely on existing documents and oral recall. It is the least accurate method.

What happens if 2ML doesn’t locate the existing utilities?

At locations where a utility line is suspected but not identified, 2ML would recommend potholing or vacuum excavation to suck up the asphalt and earth very carefully until the utility line is physically located or “daylighted”. 2ML works with the contractor to ensure that the utilities are located and identified using these methods.

Hazards Associated with Each Kind of Utility Line

Red – Live electrical lines, especially high voltage lines, pose a serious risk for workers excavating in the area.
Orange – These service lines can be either coaxial cables or fiber optic cables. The latter are far more expensive to repair if damaged.
Yellow – Gas, oil and petroleum are flammable and explosive and can cause extensive damage if struck.
Green – Sewer water is kept out of storm drains for public health reasons. It is important that sewer water be filtered and treated before it is discharged.
Blue – In areas with cold climates, potable water lines are often buried deeper than other service lines in order to be below the frost line.

How does 2ML mark and identify utility lines?

Utility and service lines are marked with flags and/or paint. 2ML uses a drone to take pictures of the markings and note location features. Point of view (POV) photos are also taken from the ground.

What Colors and Symbols are used for Marking Utility Lines?

2ML uses the Uniform Color Codes developed by the American Public Works Association (APWA) for marking the location of utilities underground.

Red: Electricity, lighting
Yellow: Gas, oil, steam, petroleum, and gaseous chemicals
Orange: Telecommunications (TV, cable, telephone, internet, traffic signals)
Blue: Portable Water
Green: Sewer and drain lines
Purple: Reclaimed water, irrigation and slurry lines
Pink: Temporary survey markings
White: Proposed excavation
