- Ingenious means ‘Clever person’ in Latin
- Engineer cleverly uses the available natural resources for the benefit of mankind
- Provides comfort to mankind and makes life comfortable.
- John Smeaton was the first self proclaimed Civil Engineer
Oldest branch of engineering, next to Military engineering. All engineering works other than for military purposes were grouped in to Civil Engineering. Mechanical, Electrical, Electronics & present day Information technology followed it.
A professional engineering discipline that deals with the analysis, design, construction and maintenance of infrastructural facilities such as buildings, bridges, dams, roads etc.
Constructions are against nature.
Application of physical, mathematical and scientific principles
for the convenience of civilization.
Began b/w 4000 BC and 2000 BC (during Ancient Egypt,
Mesapotamia, Indus Valley Civilisations).
John Smeaton was the first self proclaimed Civil Engineer
who built Eddystone Light House in 1771.
Civil Engineering is a composite of many specific disciplines that include structural engineering, water engineering, waste material management and engineering, foundation engineering etc. among many.
Buildings & Structures: Cities- Infrastructure: Transportation
- Culture: Art: Architecture
Link: Building Big Site
The Future: Without Limit!
- Giving beauty to buildings is architecture
– Enhancing the appearance
– Maintaining heritage
- Proper planning of towns & cities
– Planning the layout
– Planning the road
– Separating the commercial, residential, academic and
industrial areas
– Planning green belt
– Planning sewage disposal units
– Planning water treatment plants and water storage
units
Presently separated from Civil Engineering
- This deals with materials used for construction. Brick, tiles, soil, cement, stone, sand, steel, aggregates, glass, wood, plastics etc. include construction materials. Some are natural and many are man made.
This deals with the proper use of desired material economically and safely.
The mechanical properties of these materials shall be sufficient to avoid failure and excessive deformation and provide durability.
The chemical properties shall be to maintain good environment.
Deals with planning, scheduling and execution of construction activity related to a project.Comprises of men, material, time and money management.
Emphasis will be on new construction practice, use of appropriate and local technology, safety of men and material, utilization of marginal materials etc.
- Construction managers: – Review contracts, Order materials, Hire and schedule sub-contractors.
- The job of a construction manager is to: – Provide quality control and insure project is completed on time and. Within budget.
- Environment is the available nature around us. It includes the life support system such as water, air and land/Soil.
- Environmental engineering deals with the technology to save nature from human and natural abuse and pollution.
- The study involves balanced compromise between environment and safety.
- It deals with,
Technique of water collection, purification and supply, Waste water collection, treatment and disposal, Control of all types of pollution
All structures are founded on ground. Forces from structure are safely transferred to soil. Essential to understand ground behavior and interaction between soil and structure.Involves-
–Foundations
– Slopes
– Retaining Structures
– Highway pavement design
– Embankments and earth dams
– Tunnels, underground structures and deep cuts
To assess the quality of soil or rock to carry the structure
Proper knowledge of geotechnical eng is necessary for safety and stability of structures
Hydraulics deals with mechanics of water (fluid) flow.
- Water resource engineering deals with identification & utilization of available water resources minimizing the loss. Surface water such as river and lake water and ground water are usefully managed.
- This also deals with ground water utilization, ground water recharge and rain water harvesting.
Irrigation engineering deals with water management for agriculture purpose.
- Dams are constructed at the desired locations to store water in reservoir when the supply from river is good and to utilize for useful purpose during draught. Canals are built for the purpose. During excess input, water is allowed to main river through the body of dam to avoid flooding.
Water management involves the use of hydrologic and hydraulic principles to design:
– Drainage systems,
– Detention/retention
ponds,
– Navigational
waterways, and
– Flood control levees, dams, and lakes.
This is one of the new fields.- The improvement in space technology, availability of GPS enhanced the scope of geographic information system.
Good mapping technique helps to get required information accurately and quickly to effectively manage and monitor the available resources for optimal use.
- GIS is an hightech equivalent of map. It represents a means to locate ourselves in relation to world around us. It deals with measurement, mapping, monitoring and modeling of geographic information around us.
Structure is the assemblage of two or more basic elements such as beam, slab, column, truss, frame, shells etc.Deals with the requirements considering design for limit states of collapse and serviceability.
Involves determination of support reactions, member forces and moments, deflection and deformations.
Deals with planning of positions/layout of different elements and design (determination of size, shape and material) of component such that safety and serviceability requirements are not sacrificed, yet economy is considered.
Repair, rehabilitation and maintenance is part of structural engineering.
Dams, Bridges, Stadiums, Auditoriums, Multi-storeyed buildings are analysed & designed
Activity involved in collection of topographic features of a location for future construction.Feasibility survey, alternate and most suitable method is evolved
Helps in environmental impact assessment
- Execution of survey to collect topographic data
- Calculation and analysis of data, plotting survey data to create design maps
- Provision of line, grade and other layout works
Application of scientific approach (planning, design, operation and management) of transportation systems such as roads, railway, sea/river & air transports.It involves planning, design, construction/operation and maintenance of transportation facility.
In air strip runways, roads and railway, the study includes the design of pavement system.
Maintenance and upgradation of docks, harbors, airports, railway system based on requirements, population growth is a part of this discipline.
