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.
