Construction sites are places where buildings, roads, or other structures are built or repaired. They are often busy areas filled with workers, heavy machinery, and materials like wood, concrete, and steel. Safety is very important on construction sites, so workers wear hard hats and other protective gear to stay safe while they work. At a construction site, you might see cranes lifting heavy loads, dump trucks delivering materials, and scaffolding providing support for workers as they build. Each construction site has a plan, called a blueprint, that shows how the finished project will look. These sites are essential for creating the homes, schools, and offices we use every day.
