Introduction
Geosynthetics have been widely used in geotechnical and environmental engineering for the last 4 centuries ,these products helped in construction engineering field specially in the construction of conventional construction materials that were restricted or very expensive.
The advances on the use of geosynthetics materials in reinforcement and in environmental protection:
there are common types of geosynthetics used for soil reinforcement include geotextiles ,geogrids and geocells. Geotextiles are continous sheets of woven, nonwoven, knitted or stich-bonded fibers or yarns. The sheets are flexiable and permeable and looks like a fabric. Geogrids have a uniformaly distributed array of apertures between their longitudinal and transverse elements. These apertures allow direct contact between soil particles on either side of the sheet. Geocells are thick, three-dimensional networks constructed from strips of polymeric sheet. The strips are connected together forming a net cell that is filled by soil or concrete. In some cases 0.5m to 1m wide strips of polyolefin geogrids are linked together with vertical polymeric rods used to form deep geocell layers called geomattresses.
There are many types of geosynthetics products can be used in environmental protection projects,including geomembranes, geosynthetic clay liners (GCL), geonets, geocomposites and geopipes. Geomembranes are continuous flexible sheets manufactured from one or more synthetic materials. They are impermeable and used as liners for fluid or gas containment and as vapour barriers. Geosynthetic clay liners (GCLs) are geocomposites that are prefabricated with a bentonite clay layer typically incorporated between a top and bottom geotextile layer or...

The use of relatively short reinforcement.
The staged construction method (Fig. 8), which is one of the main features of this RW system,
consists of the following steps:
1) a small foundation element for the facing is constructed
2) a fullheight GRS wall with wrapped-around wall face is constructed by placing gravel-filled bags at the shoulder of each soil layer and
3) a thin (i.e., 30 cm or more in the thickness) and lightly steelreinforcedconcrete facing (i.e., a FHR facing) is constructed by cast-in-place fresh concrete directly on the wall face after the major part of ultimate deformation of the backfill and the subsoil layer beneath the wall has taken place.
A good connection can be made between the RC facing and the main
body of the wall by placing fresh concrete directly on the geogrid-covered wall face.

Throughout the construction industry, technology plays a role to help ease the completion of a project to all of the parties involved. The amount of technology application in the industry supports the belief that technology has a positive impact on project productivity. One of the main materials used in the construction industry that surrounds us every day, in which we overlook, is concrete. Concrete is an art form, in which it takes time and talent in order for it to be used efficiently, to produce its high strength and longevity. However, the downfall of this material is that it is extremely costly and nearly impossible to form it to an aesthetically pleasing surface. In spite of this, what if I told you that there is hope? That the dream of a material made of concrete, producing the same qualities, can be formed to any shape, and used anywhere was a reality.
Buildings such as Packard Motor Car Company Building Number Ten (1), Pacific Coast Borax, and the Weavers flour mill all used Hennebique’s (2) method of reinforced concrete construction. This method combined the column and the floor into one single structure. With reinforced concrete being a better load bearing construction material than any stone that could have been used otherwise, these building all had large, open, and efficient interiors that afforded for all kind of different programs. This large unobstructed floor plan design thus became the defacto design for industrial buildings since the building could be fitted with all different kinds of machinery to fit the needs of the owner and his
Nowadays, it will not be inept to inform that the universe is going over a construction boom. In truth, in the past few decades an entire affair of construction has altered dramatically like all other aspects of life. Currently, construction is no more just about keeping one brick above the other, but a diverse more than that. With the present scenario, the construction work encompasses all the aspects of construction like, performance, optimization, developing and designing. As an outcome, construction chemicals have become an essential part of the world construction industry. These chemicals are typically utilized to impart different properties into the layout.

I have conducted my research through interview with someone familiar with construction and development as how geometry is used in these fields.
GIS is an emerging method of data storage and interpretation. GIS is, simply put a database. It is many tables of data organized by one common denominator, location. The data in a GIS system is organized spatially, or by its physical location on the base map. The information that is stored in the database is the location and attributes that exist in that base map, such as streets, highways, water lines, sewers, manholes, properties, and buildings, etc. each of these items don’t just exist in the database, the attributes associated with the item is also stored. A good example of this would be a specific sewer line, from and arbitrary point A to a point B. Ideally, the sewer line would be represented graphically, with a line connecting the two points or something of the like. When one retrieves the information for that line in particular, the attribute data would be shown. This data would include the size of pipe, the pipe material, the upper invert elevation, the downstream invert elevation, the date installed, and any problem history associated with that line. This is the very gist of what a GIS system is.
Under the Stone, Clay, Glass, and Concrete is the Structural Clay industry which will be the primary focus of the report. Clay consists of the finest-grain particles in sediment, soil, or rock, and a rock or a deposit containing a large component of clay-size material. Clay can be composed of any inorganic materials, such as clay minerals, allophane, quartz, feldspar, zeolites, and iron hydroxides, that possess a sufficiently fine grain size. Along with organic matter, water, and air, clays are one of the four main components of soil. Physical properties of clay include plasticity when wet, the ability to form colloidal suspensions when dispersed in water, and the tendency to clump together (flocculate) and settle out in saline water. Establishments that fall within the Structural Clay Products Industry (SIC code 325) are primarily engaged in using different types of clay and other additives to manufacture brick and structural clay tile, ceramic wall and floor tile, clay firebrick and other heat-resisting products, and clay sewer pipe. The mining of clay used to make structural clay products are not included within SIC code 32.
When trying to design for automated construction systems, all parameters of a construction process must be integrated accurately and constantly to satisfy relevant parties, and finally, the quality of construction materials and products in terms of geometry, physical and design aspects will be changed. In order to reach automated construction goals, all the following aspects have to be fulfilled:

Gypsum is an abundant mineral that takes a lot of forms. The main chemical substitute to natural Gypsum is FGD Gypsum(Flue Gas Desulphurization Gypsum). It is generated by coal-fired power plants. FGD Gypsum is the end product of a wet purification procedure with natural lime that is generated according to the same laws as natural Gypsum – but in a speeded-up process taking only a few hours.
The materials used for the construction of the designed plan is steel of grade415 and to that for coloums and beams is concrete where grade of concrete for coloums is M40 and for beams is M30.
...nical Engineers study soils and rocks to make sure or investigate if a surface or a subsurface is appropriate to build a structure on or in it. One major thing that Geotechnical Engineers do is double-checking the placement of the foundations and if the soil under it could handle the amount of stress put. If soil assessment indicated something wrong with soil properties, it may be fixed through ground improvements like treating the soil mass. These processes helped in saving alot of money and time and it made buildings last longer.
Geotechnical Engineering covers the engineering properties of soils, the fundamentals of soil mechanics, and the application of geotechnical data and fundamentals to the design of foundation elements, earth-retaining structures, excavations, earth embankments and highway pavements.
