soil engineering report
An engineering report is made from the soil probe, and the probes are vertical holes in the terrain made in the soil to determine the general characteristics of the soil, and they have depth and specific knowledge of the level and thickness of groundwater, as well as taking soil samples for study and examination of these samples and conducting palpation operations, and you can know How to make a soil engineering report through the following article.
palpation
It is a hole placed in the site that will be created to take some samples from the ground, and it is implemented to conduct an engineering project and to know the nature and characteristics of the soil and the extent to which it supports the project, and it can also be done manually, open digging or mechanically.

The importance of soil engineering report
If we implement the project or build it on unknown land, the structure can fall over time, and then the building will break and then collapse, in addition, we have all seen a lot of problems due to not doing soil tests, in addition to that there are no voids and no recommendations Construction and flooring.
The importance of making a soil engineering report lies in many things, including:
1. Determine the pressure on the foundation.
2. Determine the degree of settlement.
3. Determine the way to support the limbs or sides of the pelvis.
4. Find out how strong the earth is.
5. Determine the number and thickness of the alternate layers, if any.
6. Knowing the expected stability and sequence of soil layers.
7. Determining the type of foundation proposed for construction and whether it will be a foundation, plinth or piles.
8. Determining the groundwater level.

How do sensors work
In order to be able to use the sensors correctly, information must be collected about the soil that will be built on, and this information is represented in the type of building, whether residential, factory or commercial, and whether there will be a basement or not?, and the nature of the building, whether the property is high, flat or low, Is it mud “agricultural” or desert land?

How to write a soil engineering report
After conducting and completing excavations, taking samples after any of the three time periods, and conducting laboratory and local tests, the report is prepared and contains many things, which are as follows: –
1. Introduction and the party that requested the report
2. A general description of the construction site and adjacent sites or areas.
3. The number, type and depth of wells.
4. Description of soil layers.
5. The results of laboratory and site tests.
6. The state of the groundwater level and the result of chemical analysis.
7. The degree of inclusion and the type of proposed inclusion.
8. Test plans and regression curves.
soil engineering report
Soil surveys must be carefully examined before starting work, especially the section on foundation recommendations, because it contains the following data and information:
1. The proposed operating level.
2. The type of cement used.
3. Permissible floor load.
4. Supporting side walls, excavation methods if necessary, and groundwater drainage method.

An example of a soil engineering report
This report has been prepared to present the results of soil research and the foundations of a project to build a residential tower consisting of a ground floor and four floors. The text is as follows:
“the owner’s name/
website address/
This report was submitted at the request of Mr. …….. It is related to the investigation of the foundations and soils of the project to construct a residential building with a ground floor and four lofts, and to provide the necessary arrangements and recommendations to be taken into consideration when planning and implementing the foundations of the project at /….. Location year, and location in ………..
The project consists of a reinforced concrete building with a ground floor and four upper floors.

Exploration work and field tests
1. Two holes were dug 20 meters below the surface of the natural soil at the building site.
2. The palpation was done manually and Figure No. .. The drawing shows the general location and the place where it is located.
3. The palpation and sampling were carried out every 1.00 meters each time there was a direct change in the nature of the soil. The samples were also covered with wax and placed in double plastic bags after collection.
4. Samples of groundwater were taken in the pits, standard penetration tests “SPT” were conducted on the website and the number of “N” strikes required was monitored.
5. Experiments were carried out on samples and their results were coded in the palpation sector.
ground water
The groundwater level was monitored during drilling to implement a “water emission level”, and after the pipes were withdrawn, the final water level was also monitored.
soil engineering report
These levels were also measured from the current normal surface level for each object location recorded in the table below:
1. The depth of palpation is 20.00 m.
2. The initial water level is 2.50 m.
3. The final water level is 1.50 m.

Chemical analysis of ground water
The groundwater sample from the gypsum pit was analyzed to determine the percentage of dissolved salts of chlorides and sulfates, and the results appear in the following table:
1. Chemical compounds: 325 mg/L.
2. Sulfates and chlorides: 640 mg / l.
The nature of the soil at the site is based on both laboratory and field studies of soil samples apparently taken from the body and in the laboratory, and the soil has also been stratified where there is no natural surface scratch depth in-situ at the time of excavation.
soil engineering report
It can also be summarized in the sequence of soil layers at the site as follows:
first layers
It is a layer of thick brown silt about 2 m deep, a layer of brown to gray hard silt to a depth of 12.20 m, as well as a layer of charred organic soils at a depth of 13.20 m.
This is in addition to a layer of fine clay approximately 14.20 m deep, and a layer of medium to fine gray sand, at a depth of about 20.00 m, the “end of palpation”.
Finally, and the beginning of the formation of groundwater, it settled at a depth of 2.50 meters from the surface of the earth and at a depth of 1.50 meters

second layer
It is a layer of brown soft silt about two meters deep, and there is also a layer of alluvial hard clay, brown to gray, about 12.20 meters deep, as well as a layer of charred organic soil with a depth of 13.20 meters, and next to it is a deep layer of fine silt clay with a depth of 14.20 meters Approximately.
