Abstract: This study presents a geographic information system (GIS)-based method for determining the optimal layout of a haul route for large earthmoving projects. The methodology focuses on the use of cost distance measurements to ...

Abstract: Microtunneling is a type of trenchless technology for underground pipeline construction. Using the technology, surface disruptions can be minimized. Currently, open-cut trenching is often not allowed in urban areas or ...

Abstract: Building information modeling (BIM) can facilitate effective three-dimensional (3D) earthwork modeling by furnishing insightful information. An earthwork area is generally represented in a cell-based environment for planning ...

Abstract: Productivity assessment plays a key role in successful earthwork projects and is primarily achieved by monitoring key construction equipment such as excavators and dump trucks. Vision-based methods are widely adopted to ...

Abstract: This paper discusses graphical interfaces to improve equipment control in construction and facility/infrastructure maintenance environments. Most large construction and maintenance machines are difficult to control because ...

Abstract: This study proposes a methodology to determine the optimal cross-sectional design of a high-occupancy vehicle (HOV) facility for safety performance by evaluating the effects of each relevant design element on safety and ...

Abstract: Tunnel construction fundamentally differs from building and aboveground civil infrastructure projects. Drill-and-blast is one of the most common and flexible tunnel construction methods. However, it is complex and challenging ...
