This industry is mainly divided into civil engineering and building. Civil engineering consists mainly of constructing basic infrastructure such as roads and water pipes, while building consists of constructing structures such as homes and schools. The industry also includes design, procurement of materials, and other construction related work. Japanese corporations have increased production efficiency by implementing innovative technologies. For example, measurements performed by drones and information sharing systems utilizing ICT are applied to the maintenance of infrastructure and buildings. Furthermore, autonomous robots are already used at some construction sites in Japan.
