Knowing the right moment for sale of used heavy construction equipment is important information every company. The proposed methodology uses ensemble machine learning techniques to estimate price (residual value) in both present and near future. Each model represented with four groups attributes: age mechanical (describing machine) geographical economic target market). research suggests that ba...

Two noticeable events will speed-up the development of road construction robotics the recent availability on the market of adapted localization systems, the increasingly developing utilization of computer aided design in the study of road construction projects. Currently, no links do exist between the design studies and the construction work involving digital data which could be used for progra...

Operating cranes in a construction project should meet several requirements of capacity, safety and spatial constraints. Much research has been done about selecting cranes, simulating the work processes, training operators and optimizing working paths to improve the efficiency and reduce conflicts in real construction operations. However, most of the research focused on equipment working indivi...

During a typical excavation operation, there is a high risk of inadvertently damaging the existing subsurface utilities. Such incidents cause significant financial loss to the project and can delay or abruptly halt ongoing construction. In many cases, they also pose a life threat and often result in accidental deaths. As a result, constructors are required to protect utility systems during exca...
