Sometimes the construction industry is criticized for not being innovative. The truth is, as one of the oldest industries, construction has had to adapt and innovate to the changing needs throughout the centuries of human existence.
Construction history is global history. Before humans had the means to chronicle the past, they had the knowledge and skill to build structures necessary for survival. We’ve come a long way since the days of caves and huts serving as primary residences. But to appreciate how far we’ve come, it’s important to understand where we started.
While the construction industry has, rather unfairly, gained a reputation for not being innovative, in this post we look at the history of construction innovations, who and what influenced our modern processes, and where we might go next.
While the Earth dates back over 4.5 billion years, humans have only been around for only a fraction of that time. Records suggest our ancestors date back 4.5 - 2.5 million years ago, but anatomically modern homo sapiens likely first appeared between 300,000 and 140,000 years ago. Historians and scientists often refer to this prehistoric period between 2.5 million and 1,200 BCE as the Stone Age and divide it into three distinct eras:
Throughout the Paleolithic Period, early humans made significant advancements in the tools they used. Paleolithic archaeologists note that our ancestors started using stone tools for hunting, food preparation and production, and wood chopping. However, because survival during this time period revolved around hunting and gathering, communities often changed locations rapidly, and most of the shelters these early people created were only for temporary, short-term housing.
While hunting and gathering continued into the Mesolithic period, agriculture started cropping up as a means of sustenance. This new, intentional way of producing food also gave rise to permanent settlements. Groups of huts slowly became villages, and villages evolved into cities. The communities were typically positioned near rivers, lakes, and other bodies of water.
By the Neolithic period, early people learned to cultivate plants and domesticate animals. With agriculture in full swing, the idea of protecting one’s territory emerged. Not only did people start making new weapons, such as arrowheads and axes, but they also started building walls around cities.
Archaeological evidence shows that during the Neolithic period, some villages started building subterranean structures for food preparation, preservation, and storage.
The presence of art and architecture created a new form of culture throughout the Neolithic era. Statues, engravings, pottery, drawings, and monuments, became increasingly common in cities. Moreover, people start “importing” materials during this time. For instance, the stones used at Stonehenge were likely quarried about 150 miles away from Wiltshire, England.
Two main factors mark the transition from the prehistoric Stone Age to the Bronze Age:
During the Bronze age, people discovered the utility of metal. They forged weapons and tools that were better than their stone predecessors. One of the most impressive innovations was the wheel, which allowed people to move and transport heavy objects, including building materials.
Beyond tools, people developed an appreciation for architecture and art. They started building homes with various materials like stone, wood, and thatch, and included features such as fireplaces and hearths.
Ancient Egypt is one of the most notable cultures to rise during the Bronze Age. Not only did Egyptians have organized government, law, and religion, but they made massive (literally and figuratively) contributions to construction and architecture—so massive, in fact, that we’re still puzzled by the pyramids in several ways to this day.
Ancient Egyptian architecture dates back to 3100 BCE and is widely accepted as the origin of architecture itself. Monumental in scope and creative in nature, Egyptian architecture is most known for the pyramids, temples, and obelisks (large, thin monuments with pointed tops meant to symbolize the relationship between gods and people).
Adobe (sun-baked mud bricks) was the primary construction material used in ancient Egyptian construction. Because of the hot, dry climate, these bricks hardened into a solid and formidable building material. For grander projects–pyramids and other holy sites–limestone, granite, and sandstone comprised the bulk of the building material, filling the gaps with adobe.
Despite these massive advances in architecture, the construction process was entirely primitive. Vast teams of workers pulled huge building stones using ropes and sleds, eventually dragging them up ramps and placing them accordingly.
Drawing on the full potential of the nearby Nile River, irrigation systems, ships, and steam power are all products of ancient Egyptian advancements in construction.
During the Iron Age, people discovered a way of heating and forging iron and making steel. At this time, there were also significant advances in architecture. Homes included individual rooms and were located along paved roads. Further, palaces, temples, and religious structures had multiple stories. Albeit a time of decline, Ancient Greece and Ancient Rome are two of the most pivotal civilizations of the Iron Age.
Ancient Greek temples (such as the Parthenon) are considered some of the most well-known ancient structures, a few of which still stand today. The construction of these temples consisted primarily of columns and beams, creating usable blueprints for various dwellings. What’s more, these structures were built on multi-layered foundations that allowed for natural drainage and more structural security.
In addition to temples, ancient Greece is known for its design of amphitheaters and stadiums, the blueprints of which we still use today. The semi-circular shape allowed many rows of seats to have a clear view of the stage or performance area. Amphitheaters and stadiums were often purposely built on embankments, allowing for a natural slope that reduced construction time and improved the audience’s view.
Though they first used mudbricks and wood, the ancient Greeks eventually adopted the use of marble, particularly for the construction of public buildings.
Advances in Greek mathematics gave way to advances in technology, including pulley systems that enabled builders to move weighty stone slabs easily. Precision math improved the overall structure of virtually all builds by encouraging minor corrections in design and the exact execution of architectural plans.
Moving away from the more natural building materials, Roman architects developed a hydraulic lime mortar known as Roman cement. This strong material could be easily produced and used for mass walling, allowing the Romans to build immense structures at incredible speeds.
With the installation of aqueducts, Romans enjoyed a range of new amenities, including toilets, baths, and sewage systems. Aqueducts relied on gravity to transport water along stone and concrete pipes into city centers. Though aqueducts are primarily credited to Ancient Egypt (specifically, the advent of irrigation systems), Roman mastery of civil engineering allowed them to be used for many practical purposes.
Technological innovations in Roman construction include the waterwheel, sawmill, and arch. Most notably, however, was the invention of the timber crane. This advanced technology allowed Roman builders to lift considerable weights–estimated around 100 tons–to great heights.
Due to the size of their territory, Roman’s also established intricate roadways, many of which integrated with raft systems used to transport goods along waterways.
While centuries of innovations culminated in jumpstarting The Industrial Revolution, this era marks an entirely new means of construction. From steam engines and machine tools to machine-cut fasteners and in-door plumbing, the world seemed to change abruptly in fewer than one hundred years.
Using I-beams in conjunction with reinforced concrete, buildings grew taller than previously thought possible. Suddenly, windows went from being a luxury to a household staple, property developers needed to include indoor plumbing to meet building codes, and fire safety became a priority.
In the late 19th century/early 20th century, elevators and cranes allowed buildings to scrape the skies. Power tools also rapidly increased efficiency and decreased the need for a massive workforce.
According to historians, there are four Industrial Revolutions. However, the third one contributed more to electronics and nuclear energy than construction. Conversely, The Fourth Industrial Revolution, sometimes referred to as Industry 4.0, made a massive impact on the world of construction. With the internet came a new suite of digital tools, namely construction software.
Physical blueprints started going by the wayside, collaboration began happening with people in different cities, states, and countries in real-time, and productivity skyrocketed. Some of the most essential digital tools developed in the 21st century include:
Considering one of our basic needs is shelter, it’s no wonder why construction has been a part of the human narrative for thousands of years. Even in our earliest days we found refuge in caves, built simple huts, and crafted tepees to survive. To make these dwellings more habitable and hospitable, humans innovated with new tools, materials, and aesthetics.
As we continue through the Fourth Industrial Revolution, we continue to find ways of collaborating more effectively, reducing costs, and managing large-scale projects.
