3. INDUSTRIALISED AND SYSTEM
BUILDING CONSTRUCTION.
• Introduction
• An Industrialized Building Construction (IBC) may be defined as a mass
production of building components which are assembled in factory or at
site, based on the standard shape and dimensions under strict quality control
and minimal site activities. The component then will be delivered to the
construction site to be re-arranged according to the standard requirement to
construct the building.
• It may also be defined as an investment in equipment, facilities, and
technology with the objective of maximizing production output, minimizing
labour resource, and improving quality to develop interconnected elements
joined together to enable the designated performance of a building

4. Why industrialize construction?
• The execution time: the times are reduced since the design that is used is
standard and the production has been automated
• Climate: To a large extent, the weather may no longer affect the
construction of the building
• Occupational accidents: the work environment is more controlled and the
physical and environmental conditions are more favourable.
• Improved quality of products: Industrialization will lead to improved
quality of the products. There is a greater precision and consistency in
quality due to standardisation of the construction process.
• Reduced costs: Continued development of prefabrication provides a
growing range of construction products that may further reduce construction
costs.

5. • Increased demand for buildings:
• Limited skilled labour: Increased shortage of skilled manpower to
carryout specialized building construction work.
• Reducing labour productivity: The problem of low and decreasing
labour productivity is typical of many countries.

6. Classification of Industrialization
• Off-site industrialization and On-site industrialization.
• Product industrialization and Process industrialization.

7. Key factors of industrialization
• Materials
• Methods
• Men
• Market
• Money
• Machines
• Management

8. Limitations of Industrialization
• The use of machines to replace manpower reduces on the jobs
available for human labour.
• Possibility of damage during transportation;
• Normally it requires lifting equipment;
• Monotony of design unless there are variations in the prefabricated
units;
• Over designs to take care of the loading conditions.
• The cost of the technologies and equipment is usually high at the
beginning
• Disposing of salvage equipment

9. Measure of Industrialization
• Level of prefabrication. This can be measured by the ratio of value of work
done on site to the value of work done off site.
• Extent of use of mechanization. This includes use of high-tech machines and
technologies.
• Degree of automation. The more the system is automated, the more
industrialized it is regarded.
• Use of robotics. The more the robots are used, the more industrialized the
industry is regarded.
• Reproduction (continuity of production). The more and the ease with which
products are reproduced is an indicator of degree of industrialization. This can
be measured by the time taken to accomplish the project as a ratio of the
planned time.

10. Further measures that can be used include:
• Degree of standardization. The more standardized the building components
and construction procedures are, the higher the degree of industrialization.
• Professionalized skilled labour. The skills and training of the craftsmen
should also be regarded as indicators of industrialization. This can be
measured by cost of labour as a percentage of cost of construction. The higher
the value, the less industrialized the industry is regarded.
• Organized experimentation integrated with production. The indicator of
this could be the ratio of the cost of research and development (R&D) as a
percentage of the annual turnover.
