GEOLOGICAL AND ENGINEERING DOCUMENTATION
If there are complex ground conditions detected during soil tests, there is usually a need to prepare additional documentation:
- geological and engineering documentation
[Geological and Mining Law], - documentation of subsoil tests (geotechnical foundation conditions) [Regulation of the Minister of Transport, Construction and Maritime Economy and the European standard for foundations and building structures Eurocode 7].
Often, as part of the geological and engineering documentation, a forecast of the impact of the designed objects on the environment and a description of geodynamic processes (if any) are made.
The time needed to prepare the geological and engineering documentation depends on the company that carries it out, the size of the task, and the efficiency of the offices.
Geological and engineering documentation requires approval.
It is carried out on the basis of the "Project of geological works" developed and submitted for approval. The design includes data on the designed structure, its type, dimensions, depth and foundation method. The design of geological works must be submitted to the competent office for approval due to the area of the investment and its size. In Warsaw, it is the Environmental Protection Office. Projects are submitted to the county office. Of course, you have to take into account the need to provide clarifications to clarifying questions that may be asked by the Office. According to the law, the time allowed for the Office to consider the project is up to 30 days. In special cases, the time for approval of the documentation may be extended to 60 days.
After receiving the decision approving the project from the county office, the next step is to submit information about the intention to start field work, which can be started after 14 days from the date of submitting this information.
Then, the designed soil tests are carried out as part of laboratory and field work.
As the next step, geological and engineering documentation is prepared and submitted for approval. Usually it takes about 3 weeks for approval. (This decision becomes final 14 days after its issuance).
In practice, approximately three months elapse from the submission of the geological work plan to the receipt of approval of the geological-engineering documentation. In special cases, of course, this time may be extended.
Geological and engineering documentation consists of a descriptive part and a graphic part.
The geological and engineering documentation contains detailed conclusions and recommendations regarding the method of drainage and foundation.
The graphic part includes maps showing various ranges, e.g. geological and engineering conditions, sections, sounding cards. Additionally, it includes a table with geotechnical parameters and a summary of the results of laboratory tests of soil and water (if they were performed).
The material is for information purposes only and is not an interpretation of the law. Due to possible changes in applicable law, all information provided should be verified and checked for validity.
