Abstract: This research aims to develop an alternative solution to computing the three-axis orientations of a tunnel-boring machine (TBM) during microtunneling and pipe-jacking operations. Comprehensive geometric foundations are ...

Abstract: Our research has investigated the feasibility of directly sourcing autonomous operations data from a construction-vehicle positioning system, so as to enable productivity analysis and simulation modeling in the practical ...

Abstract: This research aims to develop an automated and cost-effective solution to guide the advance of a tunnel-boring machine (TBM) during microtunneling and pipe jacking operations. Pros and cons of currently available TBM ...

Abstract: The use of automatic building information modeling (BIM) based on point cloud scans is in increasing demand in many engineering applications, such as construction progress monitoring, building renovation, project management, ...

Abstract: Earthmoving operations employ heavy-duty vehicles, including trucks and scrapers, to transport soil and rock on and off construction sites. Such construction activities are commonly scheduled and paid for based on the ...

Abstract: Automatic three-dimensional (3D) as-built reconstruction for non-Manhattan structures and multiroom buildings remains an industrywide challenge due to complex building environments and high demands for generating volumetric ...

Abstract: Installation quality check is essential for ensuring the construction quality of prefabrication construction. The existing techniques for assessing the installation quality of prefabricated wall panels heavily depend on ...

Abstract: Recent publications have shown the role that options play in addressing the uncertainty, risk, and fairness in public–private partnership (PPP or P3) agreements in toll road projects. Typically, the literature uses financial ...
