As-Built of Road Infrastructure: a workflow using the BIM-based tool OpenRoads Designer
No full textIn the context of managing the vast amount of data that pertains to processes in the AECO (Architecture, Engineering, Construction, and Operation) industry, technologically advanced methods such as Internet-of-Things (IoT) and Big Data run alongside Building Information Modeling (BIM), a methodological approach that is also booming in the transportation infrastructure sector. This expansion is driven by the increasing necessity for BIM in the designand management of smart cities which lies in the digitization of its urban fabric, encompassing both its architectural and infrastructural elements alongside its service provisions. Central to this paradigm is the utilization of BIM as a pivotal tool, facilitating the creation of citiesthat are not only intelligent and interconnected but also sustainable and fundamentally livable. This study aims to delineate a systematic workflow for the generation of a digital twin of road infrastructure utilizing the BIM-centric software, Open Roads Design, developed by Bentley Systems. The originality of the research work is to propose a methodology to create the as-built of existing infrastructure, in absence of the requireddesign project documentationand thenusing data from survey drones.Additionally, a bespoke interoperable asset manager is proposedwhich provides a decision-support tool by giving insight into project alternatives and the spatial context in which they fit, with up-to-date information that serves as a basis for managers to more efficiently and economically manage asset maintenance and operation
BIM for Heritage Infrastructure Conservation
No full textBuilding Information Modeling (BIM) technology has revolutionized the field of architectural conservation, playing a vital role in the preservation and restoration of heritage sites. The purpose of the research is to develop a broad approach for the application of BIM in horizontal infrastructures in the field of archaeology. An existing heritage stone pavement was digitally parametrically modeled utilizing a BIM-based technique. Each element was transformed from simple graphic entities into intelligent entities using a unique computational design code. In this way, the applied methodology resulted in a dynamic model that updates its information package and modifies the output of the analysis every time the data worksheet is integrated with newly collected results. As a preliminary outcome, a tool is suggested for the potential of virtual restoration, where professionals can virtually reconstruct and perceive a cultural site in its former splendor. The tool includes both graphical and non-graphical information. This will allow for the exploration of alternative restoration approaches and empower decision-makers to make informed choices
VIASTRATA®: The New Frontiers of BIM for the Digitalisation and Management of Infrastructures
No full textBuilding information modelling for infrastructure (I-BIM) is used for creating and managing data during the design, construction, and operations process of roads, railways, and airports. I-BIM integrates multi-disciplinary data to create detailed digital representations that are managed in an open cloud platform for real-time collaboration. The newly founded university spin-off VIASTRATA aims to develop digital information management methods and tools for the design and construction of roads, railways, airports and hydraulic works. Its scope also includes interventions on existing constructions and ultimately aims to the creation and products with high technological value and innovative BIM services. The chapter covers structured and innovative methodologies for designing, modelling and managing transport and hydraulic infrastructures leveraging BIM. To this end, the operation of an algorithm developed in visual programming language that realises the parametric model of a road dynamically from data contained in a spreadsheet is described
BIM As-Built Workflow for Road Infrastructure

Additionally, to streamline management processes, a bespoke interoperable asset manager is proposed
An innovative framework for integrating Cost-Benefit Analysis (CBA) within Building Information Modeling (BIM)
No full textCarrying out correctly and objectively a CBA (Cost Benefit Analysis) means planning and designing sustainable infrastructures.
For the case of infrastructures, it is very important to demonstrate in the most efficient way the impacts that would result from its construction and to show them to all the involved stakeholders.
In this context, the marriage between the CBA and BIM (Building Information Modeling) becomes a powerful visualization tool for stakeholders providing them a transparent summary of the costs and benefits of the project, within the evaluation analysis of the decision-making process. CBA-BIM is the union between infrastructural and transport planning which place Stakeholder Engagement as a central planning activity aiming at reducing the subjectivity of the analyses.
The motivations lying behind the integrated use of the CBA with BIM are the transparency, standardization, and automatization of the decision-making process. Indeed, from their union, there should be a decrease of the costs related to the protests of the stakeholders not involved bringing unnecessary delays in the construction works.
This paper shows an application of this framework, with a BIM based design approach, to the case of the Napoli-Bari High-Speed Rail corridor, currently under construction. The BIM based procedure proposed can be easily adapted to different uses according to the objectives.
This work provides a contribution to the current literature since it is one of the first which considers the integration between BIM and CBA in the infrastructural context
Systematic Literature Review of Open Infrastructure BIM
Full text linkRepresentation and modeling using the building information modeling (BIM) methodology of civil works have become the subject of increasing attention in recent years, thanks to the potential offered by Open Infrastructure BIM (I-BIM). However, the complexity of infrastructure works, i.e., the variety of construction and technological systems, makes Open I-BIM very complex and challenging. The lack of systemic knowledge on the subject is another challenging factor. The aim of the following research work is to provide a synoptic overview of the existing scientific research, accompanied by the most recent studies in the field of computer modeling, its applications, and the main opportunities that Open I-BIM offers to the infrastructure sector. After a thorough review of 198 scientific articles published between 2013 and 2023, this study systematically presents a holistic review and critical reflection on the current status of the use of Open BIM in the infrastructure sector, with a focus on the development of the tools and methods used. The outcome of this work constitutes a systematic review of the literature with a bibliometric analysis on Open I-BIM, which is able to provide a knowledge base for identifying research trends, common problems, and the potential of developed methods
Heritage BIM Approach for roman pavements
Full text linkThe growing necessity to design and digitally representation of historical pavements has led the
specialists to use different Building Information Modelling (BIM) tools to control the road design and
construction phases. In this research paper, a Heritage BIM (H-BIM) approach was developed to recreate
an archaeological road to accomplish the disruption analysis of stone pavements. In detail, within Autodesk
Infraworks the conceptual model of the road and the digital terrain model (DTM) was generated; then the
road corridor design process was performed within Autodesk Civil 3D using a parametric road section
which was created by means of Subassembly composer, a Civil 3D extension. Subsequently, a visual
programming application, Dynamo, based on Python language, was adopted to extract and update corridor
information. In detail, a workflow was developed to implement a disruption analysis of road stone
pavements and the output of the calculation were inserted in the model. As preliminary results, a tool is
proposed to support the authorities and experts during the managing processes
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Stone Paved Road Digital Reproduction: A Workflow
No full textThe growing necessity to design and digitally represent historical pavements has led specialists to use different Building Information Modelling (BIM) tools to control the road design and construction phases. In this research paper, a Heritage BIM (H-BIM) approach was developed to recreate an archaeological road to accomplish the structural analysis of stone pavements. In detail, starting from the Digital Elevation Model (DEM) generated with Autodesk Infraworks, the road design process was performed. The corridor was modelled with Autodesk Civil 3D using a parametric road section created with the Subassembly composer tool. Subsequently, a visual programming application (Dynamo) based on Python language was adopted to extract corridor information (such as areas, volumes, subassembly parameters) and apply changes based on conditions established through code scripts. In detail, a workflow was developed to implements a disruption analysis of road stone pavements. As preliminary results, a tool is proposed to support the authorities and experts during the managing process
