A Decade of Modern Bridge Monitoring Using Terrestrial Laser Scanning: Review and Future Directions

Over the last decade, particular interest in using state-of-the-art emerging technologies for inspection, assessment, and management of civil infrastructures has remarkably increased. Advanced technologies, such as laser scanners, have become a suitable alternative for labor intensive, expensive, and unsafe traditional inspection and maintenance methods, which encourage the increasing use of this technology in construction industry, especially in bridges. This paper aims to provide a thorough mixed scientometric and state-of-the-art review on the application of terrestrial laser scanners (TLS) in bridge engineering and explore investigations and recommendations of researchers in this area. Following the review, more than 1500 research publications were collected, investigated and analyzed through a two-fold literature search published within the last decade from 2010 to 2020. Research trends, consisting of dominated sub-fields, co-occurrence of keywords, network of researchers and their institutions, along with the interaction of research networks, were quantitatively analyzed. Moreover, based on the collected papers, application of TLS in bridge engineering and asset management was reviewed according to four categories including (1) generation of 3D model, (2) quality inspection, (3) structural assessment, and (4) bridge information modeling (BrIM). Finally, the paper identifies the current research gaps, future directions obtained from the quantitative analysis, and in-depth discussions of the collected papers in this area.

Datenmodellierung für Brücken

Die Datenmodellierung für Brücken (Bridge Information Modeling; BrIM) ist eine Methodik für die Planung von Brücken für das Baugewerbe. Intelligente, physische 3D-Brückenmodelle bieten eine grafische und funktionale Darstellung einer Brücke und ihrer Planungsergebnisse.

Research on the Construction Process of a Steel Truss Arch Bridge Based on BrIM

This paper combined BrIM (Bridge Information Modeling) technology with the bridge engineering to parameterize the information of a through type truss arch bridge, and BIM technology is used for information management and construction process management. Firstly, the information such as the size and material of each member of the truss arch bridge was input to the family library to construct the three-dimensional model corresponding to the plane and elevation information, which could be used for the drawing review. Then the Navisworks roaming model was used for collision check, the design development phase of the construction drawings were achieved to component geometry and the detailed tables in Revit was used to manage the materials. At last, TimeLiner in Navisworks was utilized to design the construction process so Navisworks could simulate the construction process. It is found that BrIM technology of Revit combined with Navisworks can effectively improve the communication efficiency of all side such as construction, supervision, design and construction, facilitate the industrial prefabrication of components, reduce the component collision before the construction phase, control the schedule of construction and optimize the construction process.

Comparative Analysis of Bridges Construction Methods Using Bridge Information Modeling

Bridge information modeling (BrIM) has widely become an efficient tool in the bridge engineering and construction industry. It has been used in pre-fabrication, obtaining accurate quantity surveys, and creating accurate shop drawings. This article presents the utilization of bridge information modeling (BrIM) in determining the optimum construction methods of concrete bridges in bridge projects in Egypt using systematic procedures taking into account: bridge physical properties, construction cost, and site conditions. Bridge information modeling (BrIM) has proven to be an effective tool in determining the optimum construction methods of concrete bridges. The proposed BrIM approach is capable of obtaining feasible construction methods and associated construction costs based on bridge physical characteristics.
