Welcome to Civil Engineering Website

 

Civil engineering is a discipline that deals with planning, design, construction, operation and maintenance of buildings and other infrastructures such as roads, bridges, and dams. It is considered among the oldest professions (next to military)  in the world and as such there have been many inventions, innovations and  achievements in the field. Among the famous civil engineering infrastructures include Eiffel Tower in Paris, Golden Bridge in USA, Bird Nest Stadium in China and Hoover Dam in USA.

The field of civil engineering covers wide ranges of specialties. Thus it is normally divided into sub-disciplines that include:

  • Building materials technology
  • Construction technology and management
  • Geotechnical Engineering
  • Hydraulics, water resource and irrigation engineering
  • Structural Engineering
  • Transportation Engineering

Building materials technology concerns with materials used for construction such as concrete, steel, wood, etc. Some are natural materials, others are man made. Construction materials must be made or formed to have certain properties that are required for applications in construction projects. In general the materials must be economical and safe, have proper mechanical properties to avoid failure, excessive deformation and provide durability.

Construction technology and management deals with planning, scheduling and execution activities related to construction project. The things to be managed include people, material, time and money. It gears toward new construction practice, use of appropriate and local technology, safety of men and materials, utilization of marginal materials etc. The main person in charge for this in project called construction manager. Construction manager review contracts, order materials, hire and schedule sub-contractors. The main job of construction manager is to provide quality control and insure project is completed on time and within budget.

 Geotechnical engineering concerns with soil or rock in supporting the structures above or in affecting the surrounding structures. Proper knowledge of geotechnical engineering is necessary for safety and stability of structures. All structures are founded on the ground. As such all weight of structures and occupants will be transferred to the soil.  Thus it is essential to understand soil behavior and the soil-structure interaction. The subjects that will be studied in this discipline include foundations, slope stability, retaining structures, highway pavement design, embankments and earth dams, tunnels, underground structure and deep cuts. For example, a geotechnical engineer should provide foundation of building so that the soil should  be able to resist  forces with failure or excessive deformation.

 Hydraulics, water resource and irrigation engineering deals primarily with mechanics, utilization and management of water. Hydraulics deals with water (fluid) flow. Water resources identifies and utilize the available water resources and minimize the loss. Surface water such as river and lake water and ground water are properly managed. Water resources 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 to distribute the water. During excess input, water is allowed to spill over to main river through the body of dam to ovoid 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.

Structural Engineering is concerned with analysis and designed of a structure. A structure is the assemblage of tow or more basic elements such as beam, slab, column, truss, frame, shells etc. In other words, it 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. The design must satisfy requirements for limit states of collapse and serviceability. It involves determination of support reactions, member forces and moments, deflection and deformations. Repair, rehabilitation and maintenance is also part of structural engineering. Among common structures analyzed and designed are high-rise buildings, bridges, stadiums, auditoriums, and dams.

Transportation engineering is the application of scientific approach to plan, design, operate and manage the transportation system such as roads, railway, sea/river and air transports. It involves planning, design, construction/opration and maintenance of transportation facility. Types of work include design pavement system for air strip runways, roads and railway. Maintenance and upgrade of docks, harbors, airports, railway system based on requirements, population growth is also part of transportation engineering.
