643.2.3 Determination of Existing Utilities

	For projects with scopes that have potential for utility conflicts, the minimum level of effort required is SUE Quality Level D. Locations of existing utilities are determined by requesting locates through Missouri 811, also known as the “One-Call” process. Missouri 811 locating requests should be carefully considered for the scope of work of the project. When necessary, the location of existing utilities should be established by a field survey of locate markings and features and shown on the roadway plans. Higher level SUE Quality Levels can be used on any project. Adjustment cost savings, whether to the MoDOT or to the utility owner, are beneficial to the taxpayer. Good SUE projects are typically urban in nature, or in congested areas, where the project footprint is to be minimized, or anytime accurate vertical and horizontal location of the utility facility might allow a design to avoid the utility facility thus preventing the need for the adjustment. The SUE process combines civil engineering, surveying, and geophysics. It utilizes several technologies, including vacuum excavation and surface geophysics.

The SUE process combines civil engineering, surveying, and geophysics. It utilizes several technologies, including vacuum excavation and surface geophysics.

	When proposed excavation or installation of subsurface features (drainage, equipment bases, etc.) falls within three feet (3’) of a marked Missouri 811 line, soft digging (hand digging, potholing, vacuum methods, pressurized air/water jetting, pneumatic hand tools, etc.) is required to more exactly locate the utility facility both horizontally and vertically. Utility facilities present within the right of way by permit, should be investigated by the utility owner. ~~Utility~~ facilities that would be reimbursable or partially reimbursable as defined in EP 643.2.8 will be investigated by MoDOT.

The SUE of utility facilities that would be reimbursable or partially reimbursable as defined in [[#643.2.8_Cost_Responsibility\|EPG 643.2.8]] will be investigated by MoDOT is a reimbursable expense to the utility owner. MoDOT may undertake the SUE investigation of these utility facilities utilizing a SUE provider.
