                                typically when the procedure associated with the observation was
                                completed. For some observations this is identical to the
                                samplingTime. However, there are important cases where they differ.
                                Example: Where a measurement is made on a specimen in a
                                laboratory,the samplingTime should record the time the specimen was
                                retrieved from its host, while the resultTime should record the time
                                the laboratory procedure was applied. Example: Where monitoring
                                observation results are post-processed, the resultTime is the
                                post-processing time, while the samplingTime preserves the time of
                                initial interaction with the world. </documentation>

                                injection rates to subsurface locations in pre-designed patterns in

                                hydrofracturing soil, creating lenses. The lenses compact
                                surrounding soil and then lift the overlying soil and structures.
                                Jet - consists of breaking up the soil with a high-pressure jet in a
                                predrilled borehole and mixing the loosened soil with a cement grout
                                alone or mixed with air and/or water. Permeation - Introduction of

                                change in the original soil volume and structure, changing the

                                the injection of specially formulated cement-based mixes into the
