Mechanization in Construction Industry- Motivations, and Advantages

Mechanization in Construction Industry

Reading time: 1 minute

Mechanization is the process of shifting from working largely or exclusively by hand to do that work using machines. The construction projects are becoming more demanding and complicated in construction and delay of projects would arise if conventional construction method is used.

Delays in construction are costly and have prompted developers to embrace mechanization. Construction machineries are used in order to achieve larger output, cost-effective, execution of work that is not feasible by manual efforts, reduce the amount of heavy manual work which would cause fatigue, maintaining large output, and finalize projects on time.

Mechanization is based on rented construction equipment is cost effective. construction equipment when rented can be exactly to match the requirement. For rented equipment, time to make the equipment ready for operation is important.

Factors Affecting Selection of Construction Equipment

  1. Availability of equipment.
  2. Suitability of job condition with special reference to climatic and operating condition.
  3. Uniformity type; easier operation and maintenance, easy exchange of spare parts and operating personnel.
  4. Size of equipment.
  5. Use of standard equipment; made by several companies so that easy purchase and delivery.
  6. Country of origin; If importing foreign exchange facility should be easily available.
  7. Unit cost of production – cost of running.
  8. Availability of spare parts and selection of manufacturer.
  9. Availability of local labour for operations.
  10. Function to be performed.
  11. Capacity of the equipment.
  12. Method of operation and its limitations.

Advantages of Construction Mechanization

  1. Economical
  2. Improve construction quality
  3. Increase safety of construction conditions
  4. Enhance speed of construction
  5. Feasibility

Disadvantages of Construction Mechanization

1. Loss of Skill

The craftsman with the superior skill had disappeared. Such skill is no longer necessary. The only type of skill that is needed now is to run the machines.

2. Dependence

Machinery has increased our dependence on others. We depend for our water and light on the satisfactory working of water-works and the power-house.

A small flaw would result in the supply of these necessaries being cut off at any time. This may mean not only inconvenience but serious dislocation of normal life.

3. Insanitary Surroundings

Big factories pollute their surroundings and make them filthy and insanitary. This has led to moral degradation and physical deterioration.

4. Over-specialization

Machinery leads to too much specialization. This over- specialization increases the risk of unemployment and cramps the worker physically.

5. Class-conflict

Use of machinery is responsible for class-conflict—the capitalist on one side and the laborer on the other.

6. Unemployment

 It creates unemployment because one machine can take the place of several men.
