Subsurface Utility Engineering (SUE)


                             John A. Grant, Jr., Inc (JAG), employees have obtained
                     OSHA HAZWOPER certification and FDOT
                         Intermediate Work Zone Traffic Control.

                         The SUE process includes designations for underground
                         utilities as defined by the FHWA for SUE services and conforms
                         to the American Society of Civil Engineers (ASCE)
                         Standard CI/ASCE 38-02 for the collection and depiction
                         of existing subsurface utility data. SUE is an engineering
                         process utilizing state-of-the-art technology to identify,
                         characterize and map underground utilities prior to
                         excavation and design of new structures or installation
                         of new underground assests.
                         JAG provides all levels of SUE.

                         Quality Level D:
                         The most basic level of information is obtained,
                         requiring a search of all reasonably
                         accessible utility databases.

                         Quality Level C:
                         This level requires a visual inventory to ascertain
                         the general accuracy of the plans obtained
                         during the Level D phase. The visual inventory
                         may include, but is not limited to, above-ground
                         infrastructure associated with utilities such as
                         manholes, valve boxes, utility poles, etc.

                         Quality Level B:
                         The level in which geophysical methods are employed
                         to designate the existence and horizontal location
                         of utilities within a project area.

                         Quality Level A:
                         Vacuum excavation is employed to safely expose utilities,
                         providing an exact three-dimensional location and positive
                         identification of the utility. This level provides for the
                         visual verification and measurement of precise
                         and vertical positions of utilities.

                         Vacuum Excavation:
                         A non-destructive method for obtaining detailed
                         information on underground utilities and objects such as:
                         size, configuration, condition & vertical elevation.
                         The procedure begins with cutting a small hole
                         into the ground surface. Then a combination of
                         compressed air and high-pressure vacuum are used
                         together to extract the spoil and safely expose the target.
                         After information is collected, a full restoration is completed.
                         Upon request a summary of our findings is produced and
                         provided to the client in a specified format.
