Utility Designating, Mapping + Locating
UPI determines the existence and horizontal position of underground utilities using surface geophysical techniques. This level includes obtaining two-dimensional mapping information, which assists in decision-making for design, utility relocations + installations. UPI follows ASCE/CI 38-02 Standards, Quality Levels D, C, B.
UPI utilizes highly effective, minimally invasive vacuum excavation equipment to safely expose subsurface utilities. We measure + map these utilities and provide our client with a precise report, which includes horizontal + vertical locations of utilities, diameter of the utilities + the composition of the utilities. UPI follows ASCE/CI 38-02 Standards, Quality Level A.
Ground Penetrating Radar (GPR)
Ground Penetrating Radar (GPR) increases our precision when combined with traditional locating methods. GPR is used to map utilities made of metal, plastic, PVC, concrete + natural materials. UPI follows ASCE/CI 38-02 Standards, Quality Level B.
UPI identifies the utility companies + service providers who may have facilities within the project limits, initiates contact with the utility company to research the extent of facilities and provides research + document retrieval. Any records obtained during research are included with our deliverable. UPI follows ASCE/CI 38-02 Standards, Quality Level D.
