                This report is submitted on request / ------------------- for a study

               Soil and foundations for the project / ------------------- Location / -------------------

             The purpose of the report is to:

1- Study of natural and engineering properties

Soil and field and laboratory experiments.

2. Making special recommendations and precautions

Establishing and determining the quality of the foundation.

                                   2 - Location and general description of the project :

The land of the site to be implemented in the area of ​​---------

The project is a structure

                              Of reinforced concrete consists of basement + ground + 8 lofty loft.

                                            3 - Sensors and nature

                                                 Active Soil:

- Justin was executed at the site 20 meters deep from the natural surface as shown

Figure (1) was performed manually.

- Samples were extracted by sample per meter and at

All significant changes in the soil during the drilling of each grove, and the packaging of samples extracted according to specifications

Standard.

- Groundwater levels were monitored by the locations of the basins,

Samples were also chemically analyzed.

- Experiments were carried out on samples and their results were recorded

In the sector.

- Standard penetration tests ( SPT) In the locations of the sensors and the number of beats was monitored ( N) Needed to penetrate the hack

The standard is 300 mm wide with a weight of 63.50 kg, falling from a height of 76 cm.

The samples of the extracted samples were examined visually and laboratory, then classified and the sectors were drawn

Lengths of the sores as shown in Figures (2, 3). The following is a summary of the sequence of layers.

Session 1:

1-      A layer of landfill continued from the current natural surface to a depth of 1.00 m.

2-       A layer of solid brown clay up to a depth of 5.30 meters.

3-      A layer of solid gray clay up to a depth of 10.30 meters.

4-      A layer of gray clay with pockets of limestone up to 11.20 meters deep.

5-       A layer of carbonized organic soil up to a depth of 12.20 meters.

6-      A layer of soft gray clay to a depth of 13.10 meters.

7-      A layer of soft gray clay with sandy pockets up to a depth of 14.30 meters.

8    -   layer of yellow sand average roughness up to a depth of 17 meters.

9 - layer of soft yellow sand to a depth of 20.00 meters.

        (End of the session).

Session 2:

A layer of mixed mud-brick fill

Decomposed from the current natural surface to a depth of 1.10 m.

A layer of brown clay that is so cohesive

Depth 5.20 meters.

A layer of gray clay so cohesive

Depth 11.40 meters.

A layer of soaked organic soil

Depth 12.30 meters.

A layer of soft gray clay

Up to a depth of 13.50 meters.

A layer of soft gray clay

It has sand pockets up to 14.00 meters deep.

A layer of medium yellow sand

Hardness up to 17.10 meters.

A layer of soft yellow sand up

Depth 20.00 meters. (End of the session).

4. Groundwater chemical analysis

Levels:

The groundwater level was monitored during the drilling for the implementation of the gauges

The final water after the extraction of the pipes of the grooves and the completion of drilling and these levels are measured

5. Summary and Recommendations

Of Foundations:

From the study of nature

Soil and Groundwater We recommend the following:

 If the soil is different from the contents of the present report, the Bureau shall be consulted immediately

Drilling.

 - The foundations are designed to withstand basement + ground + 8 loft frequent.

 The contractor must support the drilling aspects so as to prevent the collapse of the neighboring facilities before starting

Implementation and monitoring during implementation and ensure their safety.

-   You should inquire about the location of telephone cables, electricity and gas pipes at the desired location

To avoid any foreseeable damage during the implementation period.

-   The entire site is drilled at a depth of 3.50 meters from the current natural surface.

-   Groundwater must be disposed of in an appropriate scientific manner to prevent soil granular disturbance.

 - The net foundation effort should not exceed 1.10 kg / cm 2 (one and one ten kilograms per

     Centimeter square).

- It   should be established using a 50 cm concrete concrete layer, topped with concrete

     Armed forces.

- The   percentage of aggregates used is 0.8 mلطl + 0.40 m3 / m3.

- The cubic meter of the concrete concrete foundation contains 300 kg sulfate resistant cement,

-   The cubic meter of concrete reinforced concrete contains 400 kg of sulfate resistant cement.

-   The concrete cover shall not be less than 7 cm in foundation work.

-   The foundations around the foundations are cleaned with clean sand, to be applied to the layers and compacted thoroughly.

-   The foundations should be well isolated.

-   The insulating layers shall be carried out in accordance with the technical specifications and according to the industry fundamentals.

 It takes into account the Egyptian Code of compliance with concrete structures, loads, soil mechanics and design

The implementation of the 1995 foundations and each of them is complementary to these recommendations
