ROLE OF CONSTRUCTION IN ECONOMIC DEVELOPMENT
ROLE OF CONSTRUCTION IN ECONOMIC DEVELOPMENT
Provides for economic development and expansion of economic activities
Major consumer of physical and natural resources
Produces waste
Pollutes environment
BUILDING MATERIALS
“You employ stone, wood and concrete and with these materials, you build homes and places: that is construction” – Le Corbusier
Attitudes Towards Building Materials
Possibilities and appropriateness
Attitudes
Efficiency of use (engineering point of view)
Adequacy of performance
Longevity of the building
Overall fabric
Internal fabric
Cultural attitudes
Availability of materials
Economics of choice
Transfer of technology vs. real needs
Awareness of choice
Engineering categorization of materials
General knowledge of material vs. small individual
Knowledge: cumbersome
Helps predict performance
Knowledge gained by experience and failures
Building – not just on economic viewpoint
Transfer of technology
Appropriateness
Must not be liberal in use of common ways of materials
Use of materials economically
Risk assessment
Detailed choice of materials
Environmental constraints
Durability of materials against stress
Limiting total energy demand of buildings
Parameters in decision making:
1. Environment
Storms
Global warming
2. Pollutants
Inadequate air changes
Adhesives of composite boards, paint, cleansers, propellants, plastic and insulation materials
3. Health
Exposure to substance of known toxicity
Asthma causing substances
Dermatitis causing substances
Substances that may cause skin cancer (coal, tar)
Choosing the building system:
1. What will give the required functional purposes and performance?
2. What will give the desired aesthetic results?
3. What is possible/legal?
4. What is most economical?
5. How can we build in a sustainable manner?
SUSTAINABILITY
Meeting the needs of the present generation, without compromising the ability of future generations to meet
