1.1.1. Pre-Industrial Revolution

Early human history can be dated back to the Stone Age in the Palaeolithic period (2.5 million years ago – till 10,000 BCE) when early man followed nomadic ways of the hunter-gatherer, lived in caves and huts or tepees and had begun to develop rudimentary tools of stone and wood.

In the beginning of human history, during the Stone Age, people lived nomadically. This means they moved around often, hunting and gathering food rather than settling in one place. They built simple shelters like caves or huts. During this time, humans started to make basic tools using stones and wood, which laid the foundation for future developments in building and civil engineering.

Imagine a camping trip where you set up a tent in the woods. Just like the early humans who needed to create a safe place to stay while hunting for food, you build your tent to protect yourself from the weather. The tools you use, like a hammer or knife, are similar to the rudimentary tools early humans created.

But around 10,000 BCE, a shift in climate and discovery of farming led the Neolithic man to settle, mostly along riverbanks, with focus on production of food. This in turn, led to the need to build secure habitation, plan settlements, and land use, construct transport and irrigation systems, and design solutions towards water supply and sanitation, which can be identified as the first examples of civil engineering.

Around 10,000 BCE, a significant change occurred when humans discovered farming and began to cultivate land. With farming, people could produce their own food, allowing them to settle in one area, primarily near rivers for easy access to water. This led to the development of secure homes, organized settlements, and the need for systems to transport water and manage agriculture, which are all early forms of civil engineering.

Think about starting a garden at home. When you decide to plant vegetables, you first build a fence to protect your plants and create a watering system to ensure they grow. Just like you plan your garden, early humans planned their settlements to improve their lives and support farming.

In the following era, known as Bronze age, the social organisation altered with kings and leaders emerging and early towns being established, leading to the migration of people for better wages and employments. Skills, tools, and techniques that were handed down from generation to generation of skilled artisans, stonemasons, and carpenters, in a small locale developed into expertise and artistry that led to the rise of planners, architects and engineers, tackling projects traversing regions and empires.

The Bronze Age marked the rise of organized societies with leaders and the establishment of early towns. People began to migrate to areas with better job opportunities. This era also saw the development of specialized skills among artisans, stonemasons, and carpenters, creating a need for planners and engineers. Their combined expertise enabled them to undertake larger projects across different territories, showcasing advancements in civil engineering.

Imagine how a small town grows into a city. As it becomes more populated, new jobs open up, and people specializing in different crafts start to emerge. Just as engineers and planners work together to create the blueprints for a new city, early civil engineers evolved from skilled artisans to design infrastructure for growing urban areas in ancient times.

Between 4000 and 2000 BC, the profession grew from being utilitarian to being a creative practice of achieving feats of grandeur as is exemplified in the intricate planning of urban housing, sanitation, and water systems in the Indus Valley civilisations; decadent pyramids and monuments of Egypt; Qanats in Persia and Mesopotamia; Stonehenge in UK and the Great Wall of China; where functionality and aesthetics paralleled each other.

During this time period, civil engineering evolved from purely functional construction to more artistic and grand designs. The civilizations of the Indus Valley, Egypt, Persia, and Mesopotamia demonstrated sophisticated urban planning, including housing, sanitation, and water systems that balanced both practicality and beauty. Monumental structures like pyramids and iconic landmarks like Stonehenge and the Great Wall of China show this blend of artistry and functionality.

Think of a beautiful city park with a playground, walking trails, and a fountain. It serves a practical purpose for recreation and relaxation, yet is also visually appealing. Similarly, ancient civilizations created structures that not only served their communities but also became lasting symbols of their cultures.

Most of the construction efforts were achieved by manual labour and non-mechanised tools, however, two major global occurrences, namely, the Agricultural Revolution and the Industrial Revolution, created a huge demand of infrastructure for, housing, transportation, sanitation, and water management, and eventually for environmental planning and construction management.

While construction was mainly performed using manual labor and simple tools, significant shifts in society during the Agricultural and Industrial Revolutions increased the need for infrastructure. This included housing, transportation systems, sanitation facilities, water management, and eventually, broader aspects of environmental planning. Civil engineering became essential to support these expanding societal needs.

Consider how cities grow as populations increase. More homes, roads, schools, and public services become necessary to support the residents. Just like modern cities need infrastructure to function effectively, ancient civilizations had to develop similar systems as they grew, driving advances in civil engineering.
