What do you mean by investigation?
Interpretation of survey: (dynamic) survey: ~ well location | After years of demonstration, the dam foundation of the Three Gorges Project has been determined.

Explanation:

The measurement part of building engineering mainly includes the composition and use of measuring instruments, general measurement, industrial and civil building measurement and other measurements; The part of architectural engineering investigation mainly includes the basic knowledge of architectural engineering investigation, geotechnical engineering test, geotechnical engineering analysis and evaluation, special soil and special geological conditions, and hydrogeological investigation.

Refers to the floorboard of investigation, exploration and measurement.

Investigate and measure the site before construction.

The differences between investigation and investigation are as follows:

1. investigation: refers to field investigation or inspection, which is mostly used before mining or engineering construction. Sampling the geological test conducted by the engineer before the design, so as to provide the geological exploration report for the design. Such as site survey and topographic survey.

2. Survey: Survey refers to observing, measuring and depicting various geological elements directly or indirectly related to the project in the survey site and its periphery with standard topographic map or geological map as the base map, so as to provide a basis for comprehensively drawing the engineering map, preliminarily judging the engineering geological environment of the survey site, and reasonably arranging the exploration and test work. Investigation is the further work after investigation.

Application scenario:

From the professional point of view, according to the catalogue of undergraduate majors in national ordinary colleges and universities, there are no exploration majors in higher education, but there are exploration majors. Specifically, geology has two majors: exploration technology and engineering and resource exploration engineering.

From the industry point of view, according to the classification of national economy industries, there are related industries in exploration and development, all of which belong to the category of "professional technical services" under the category of "scientific research and technical services". Specifically, the industry involved in the survey is 7483 "Engineering Survey Activities" under the category of "Engineering Technology and Design Services", with the code of 748.

Refers to the engineering survey, engineering geological survey, consulting and other activities before the construction of a building project. The industry involved in exploration is classified as "geological exploration" with code 747, which refers to geological exploration, testing, monitoring and evaluation, engineering geology and scientific research of mineral resources.

Including all the following sub-categories: energy mineral geological exploration, fixed mineral geological exploration, mineral geological exploration such as water and carbon dioxide, basic geological exploration and geological exploration technical services.
