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.
