Inspect jobsite before transporting equipment. Check for the following:
• overall grade or slope
• changes in elevation such as hills or open trenches
• obstacles such as buildings, railroad crossings, or streams
• signs of utilities
– “buried utility” notices
– utility facilities without overhead lines
– gas or water meters
– junction boxes
– drop boxes
– light poles
– manhole covers
– sunken ground
• traffic
• access
• soil type and condition
• water supply
• sources of locator interference (rebar, railroad tracks, etc.)
Have an experienced locating equipment operator sweep area within 20’ (6 m) to each side of bore path to
verify previously marked line and cable locations. Mark location of all buried utilities and obstructions.
Take soil samples from several locations along bore path to determine best bit and backreamer
combinations.
