Construction | Class 9 Skill Education Notes

Introduction

Construction is the process of building structures that people use in their daily lives. It enables safe living, comfortable travel and work, and protection from weather elements such as heat and rain. Historically, humans initially took shelter in natural caves. As they settled and began agriculture, they constructed simple homes using mud, grass, wood, and stones. Over time, construction evolved with the use of bricks, cement, iron, and steel, allowing stronger and longer-lasting buildings. Urbanization led to the development of towns and cities, increasing the demand for houses and facilities. Due to limited space, multi-storey buildings became common. Besides houses, other structures like schools, hospitals, shops, factories, roads, bridges, and railway stations became necessary, making construction a vital sector contributing to national progress. Modern construction combines traditional skills with advanced tools, machines, and materials. This chapter explores the materials and steps involved in building structures.
