The high complexity of modern large scale construction projects leads their schedules to be sensitive to delays. At underground construction sites the earthwork processes are vital, as most of the following tasks depend on them. This paper presents a method for estimating the productivity of soil removal by combining two technologies based on computer vision: photogrammetry and video analysis. ...

In the period between 1992 and 2002, struck by vehicles and struck by objects (e.g., vehicle parts, vehicle loads, or falling vehicles) were identified as the causes of 30% and 24% of deaths on excavations sites, respectively. It is therefore of a paramount importance to improve the safety of construction sites by increasing the peripheral awareness of the operators of earthwork equipment. The ...

Sewer blockages delay sewage discharge or cause it to overflow, which pollutes the environment and is a public health hazard. This necessitates quick accurate identification positioning of sewer blockages. Following blockage, intercepted liquid level at upstream downstream blocking point changes. study established method for identifying by analyzing range rate change point. Through pilot-scale ...

Geographic Information System (GIS) is a vital tool used in numerous areas related to natural science and engineering studies. Managing complex data obtaining accurate results from the analysis are essential functions of GIS. It also efficiently highway designing both project application phases. This study proposes new calculation method slope angles determine suitable modal road by using topog...
