Abstract: Collaboration, communication, and interactions between project stakeholders have a high impact on the overall success of complex capital projects. To manage these projects and their complex nature, new methods that can ...

Abstract: This paper presents a new approach that allows automated recognition of three-dimensional (3D) computer-aided design (CAD) objects from 3D site laser scans. This approach provides a robust and efficient means to recognize ...

Abstract: Materials tracking and locating, which can be accomplished through various technologies and data sources, are key elements affecting construction productivity. The need for developing fundamental methods to take advantage ...

Abstract: Despite a decrease in industry level measures in construction productivity, there has been a steady increase in construction productivity at the activity level. This research examines equipment technology as one factor ...

Abstract: In this paper, an interactive critical operations planning environment (COPE) is described for planning critical construction operations involving large semistationary equipment such as cranes, concrete pumps, and manipulators. ...

Abstract: Heavy lift planning has a major impact on construction sequencing, scheduling, budgeting, and safety. This paper addresses problems presented by planning for multiple lifts on a single jobsite. This is a common and ...

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: Labor performance drives construction project performance. Labor performance can be improved by increasing the direct-work rate, which is the time spent by workers on installing materials and equipment. However, setting ...
