The mode of transportation that we presently have been dramatically modified with technology and this may be attributed to the modern railroad system, infrastructures such as roads and bridges and the invention of the aircraft and the automobile. These innovations are due to man’s ingenuity in the field of engineering, science, and mathematics.
Years before, when the automobile or any other machine-powered form of transportation is yet awaiting invention, traveling and transporting animals and farm produce remain a big problem. Imagine how slow the transportation was as people use donkeys, horses and among others pulling carts, wagons, and carriage to transport people and products to their destinations. Social issues and medical problems were not solved promptly and appropriately because of the delays incurred as a result of transportation problems and information dissemination.
The history of how the infrastructure system may have started may be difficult to trace as footpaths, which were first traveled by horses and other animals were then widened to make room for wagons, carts and among others until they became developed, with the invention of automobiles, for cars and buses to travel on. The fact that cars got better, roads and bridges were constructed and improved as more inventions have arrived.
Traveling fast and convenient would not have been possible if not due to the invention of heavy equipment and machines that replaced harrowing manual labor. Instead of doing the work manually, men operated these giant machines to excavate land, lift objects weighing hundreds of tons and among others.

The World Trade Center in New York was built by thousands of men and machines and only to be destroyed to rubbles also by men behind machines. Currently, buildings that were built for years can now be easily toppled in minutes because of the different inventions made by man. Consequently, the power of human technology can never be questioned.
If you are in a construction business, having various types of equipment for digging, lifting, pulling objects such as pre-casted posts, steel frames and among others get the work done fast, efficient and convenient. If you are beating deadlines in your contract, all the more that you need heavy equipment to finish the work before the deadlines and before somebody sues you and your company.
