UCSB English Dept: Alan Liu: Study Materials

Overview

• Discussion of the antiquity of bricklaying as a trade and its historical lack of improvement.
• Introduction of scientific management principles to bricklaying by Mr. Frank B. Gilbreth.
• Examination and elimination of unnecessary movements in bricklaying to improve speed and efficiency.

Mr. Frank B. Gilbreth's Innovations

Analysis and Motion Study

• Careful study of bricklayer's movements to eliminate unnecessary actions.
• Emphasis on substituting fast motions for slow.
• Detailed analysis of foot positioning relative to wall, mortar box, and brick pile.

Scaffolding and Material Positioning

• Design of a scaffold with a table to maintain proper relative positions of materials.
• Adjustable scaffolding to reduce physical exertion and streamline process.

Brick Sorting and Handling

• Careful sorting of bricks before use.
• Placement of bricks on a wooden frame for easy handling.
• Avoidance of extra time spent turning and examining bricks.

Mortar Preparation

• Adjusting mortar consistency to eliminate tapping bricks with the trowel handle.

Reduction of Movements

• Reduction of movements from 18 to 5 or even 2 per brick.
• Analysis detailed in "Motion Study" chapter of Gilbreth's book, "Bricklaying System".

Methods of Improvement

Elimination of Unnecessary Movements

• Careful study and trial to identify and remove useless movements.

Introduction of Simple Apparatus

• Adjustable scaffold and frames for bricks to minimize tiresome motions.

Simultaneous Use of Both Hands

• Teaching bricklayers to use both hands simultaneously to save time.

Challenges in Implementing Improvements

Historical Lack of Simplification

• Despite the long history of the trade, simplification has been minimal.
• The necessity of enforced standardization and cooperation for faster work.

Role of Management

• Responsibility of management in enforcing standards and cooperation.
• Management must provide training and monitor progress.
• Need for extra pay incentives for workers to adopt new methods.

Scientific Management Principles

Key Components

• Development of a science of bricklaying by management.
• Careful selection and training of workmen.
• Continuous management involvement and support.
• Equal division of work and responsibility between workmen and management.

Importance of Leadership

• Emphasis on a leader who is optimistic, determined, and patient.

Conclusion

• Mr. Gilbreth's method showcases true and effective cooperation.
• Success attributed to scientific management principles rather than individual initiative.
