chapter 1 (done)

historycal developement of technology :-
  • Pre Industrial society
  • Industrial society
  • post industrial society

pre industrial society - steam roadengine design by james watt

Industrial society - telephone, motor car, electronic computer.

Post industrial society - intelectual, information is encoded in comprehensive technological

Growth of Technology :-

application of scientific knowledge for practical application in the product, commercialization and distribution of good services

Development in engineering Technology :-

  • engineering material ( concrete, steel, plastic, etc)
  • power ( stem to turbine, nuclear, etc )
  • transportation ( railway, road, etc )
  • computer ( fax, email, etc)


  • posessing or promoting new industries created by production, distribution and use knowledge and information
  • characterized in continuous learning and new knowledge application
  • operate by principle, investment in knowledge provide increasing in return


  • Failure - engineer is seen as the main contributing factor for the failure
  • Eng - play a very important role in a multi disciplinary project team
  • Eng - responsible fo ensuring that the building will stand for as long as its design life.


1. safety and healt of the public

  • to identify all safety and health risks

2. country developement

  • contributed very significantly to a country's developement

3. longer life of population

4. comfirtable life of public

5. good comunication

  • these were input and built from electrical and electronic engineering

6. Transportation

  • good transportation such will open for new business opportunity

why underdevelopment country need A.T??

  • low gross national capital
  • high birth rate
  • high unemployment
  • inequality income
  • low rate of capital formation
  • poor infrastructure
  • poor services

criteria for deciding if tech is appriotiate or not

  • reasonable cost
  • influance on the local culture

responsible of civil engineer to Appropriate Technology

  • the end of product will be good quality
  • within schedule time
  • least cost
  • minimum risks

Scope A.T

  • Food, argiculture and argicultural engineering
  • water and health
  • energy
  • medical, building, roads and other services
