In contrast to the production of construction materials, the construction equipment and heavy machinery is not expended in the construction of buildings or infrastructure. These heavy machineries such as excavators, backhoe, and dozers have an average service life of about 7–10 years if properly maintained. Without a clear methodology to estimate the demand for construction equipment and machinery from the total projected investment and the rate of obsolescence, it is difficult to match the existing machinery with the current and future demands. It is encouraging to see a consistent production of heavy machineries domestically and large number of imported heavy machineries reflecting important capital investments into the construction sector.

As the purpose of the 3D surround sensor of the intelligent excavation robot is to model the 360° area surrounding the excavator, definitions concerning the specifications of the intelligent excavation robot and the working area to be excavated must first be provided. In this research, we used Doosan Infracore’s DX-140LC, an excavator with a height of 2.8 meters, boom and arm length of 4.0 meters and 1.9 meters, respectively, maximum excavation distance of 8.2 meters, and maximum excavation depth of 5.0 meters from the ground.
