Civil engineers are involved in the precise measurement of the earth’s surface to obtain reliable information for locating and designing engineering projects. Current practice makes use of satellites, aerial and terrestrial photogrammetry, and computer-processing of photographic imagery. Radio and TV signals from satellites scan by laser and sonic beams are converted to maps that give highly accurate measurements for boring tunnels, building highways and dams, plotting flood control and irrigation projects, and for virtually all the other areas of civil engineering. This technical specialty has indeed embraced modern technology.
Surveying is the means of determining the relative position of points and the relative distances. It is an integral part of Civil Engineering education and training. Surveying of an area is essential for the design of all civil engineering projects such as highways, bridges, railways, water supply, sewage disposal, reservoirs and dams, building constructions, transmission tower, irrigation canal etc. The objectives of surveying may vary depending on the type of projects and requirements. The economic feasibility of the engineering projects cannot be properly ascertained without undertaking a survey work.
Surveying is the art of determining the relative positions of different objects on the surface of the earth by measuring the horizontal distances between them and vertical angle either in elevation or depression from the observations obtained is corrected and plotted on paper to prepare the map in the suitable scale. Thus, in discipline, the measurements are taken in the horizontal plane as well as vertical plane.
The objective of surveying laboratory is to make student familiar and competent enough to draw map in suitable scale by using different surveying instruments like total station, theodolite, auto level, global positioning system (GPS), geographical information system (GIS), electromagnetic distance measurement (EDM), plane table, compass, etc. Students learn to survey from conventional as well as contemporary methods and technology. Our Surveying labs provide students with hands-on experience using common surveying equipment.

Civil engineers are required to have necessary engineering geological knowledge to solve geological problems in engineering, so as to achieve the purpose of rational development and utilization of land and environmental protection.
Engineering geology deals with the study of the structure of the earth in relation to civil engineering for the execution of safe and cost-effective design for construction projects.
Every civil engineering work involves earth and its features. Geological information is necessary in every stage of the project be it planning, designing or construction phase of the project.
The importance of geology in civil engineering may be briefly outlined as follows:
- Geology provides a systematic study of the structure and properties of construction materials and their occurrence. The civil engineers need to know the properties of rocks accurately to enable them to consider different rocks for any required purpose that is as a foundation rock, as road metal, as concrete aggregate, as building stones, as the roofing material for decorative purposes.
- The selection of a site is important from the viewpoint of stability of foundation and availability of construction materials. Geology provides knowledge about the site used in the construction of buildings, dams, tunnels, tanks, reservoirs, highways and bridges.
- Geology helps to identify areas susceptible to failures due to geological hazards such as earthquakes, landslides, weathering effects, etc.
- Knowledge about the nature of the rocks is very necessary for tunneling, constructing roads and in determining the stability of cuts and slopes.
- The foundation problems of dams, bridges and buildings are directly related to the geology of the area where they are to be built.
- The knowledge of groundwater is necessary for connection with excavation works, water supply, irrigation and many other purposes. Hydrological maps provide information about the distribution of surface water channels and the groundwater depth.
- Geological maps help in planning civil engineering projects. It provides information about the structural deposition of rock types in the proposed area.
- Geology helps in determining the earthquake-prone areas. If any geological features like faults, folds, etc. are found, they have to be suitably treated to increase the stability of the structure.
- The knowledge of erosion, transportation and deposition (ETD) by surface water helps soil conservation, river control, coastal and harbour works.
- A geological survey of a site before starting a project will reduce the overall cost.
Properties of the materials are very important in the process of designing the durable components/machines/structures etc. These properties include mechanical properties, thermal properties, electrical properties, optical properties or magnetic properties or deterioration properties. Mechanical engineers are mainly concerned with the mechanical properties like strength, ductility, hardness, brittleness, toughness, creep, fatigue strength of the materials. These properties play an important role for the structures and components that are intended to sustain various types of loads under the given service conditions. Different applications need specific mechanical properties. Sometimes hardness is required at the surface of the components, like gears, to make them wear resistant and sometimes toughness is required to resist impact loading.
This laboratory provides the know-how of the mechanical properties of the materials through various experiments on testing machines and equipment. Mainly destructive testing is used to determine different mechanical properties of the given specimen.
These testing procedures include tensile testing, hardness testing, torsion testing, fatigue testing, impact testing etc.
