A Descriptive 3D City Information Model Built From Infrastructure BIM

This study developed a descriptive 3D city information model (CIM) using only infrastructural building modeling tools to create maps, and analyzed the model according to needs identified in interviews with public-sector actors and a bibliometric analysis. The interviews assessed the challenges of implementing CIM in the Brazilian city of Curitiba, while the literature study determined that current academic production reflects the current reality, calling attention to relevant issues. The experimental software solution successfully created 3D informational modeling of cities for passive use as well as maps to support decision making, although it did not offer advanced parametric tools for urban analysis. Still, this model provides a flexible approach to overcoming the challenges reported by interviewees, which included financial limitations and organizational culture.

Training of specialists for transport construction in the context of digitalization

The main goal of the study is to determine the direction of transformation of “SibADI” FSBEI HE as a center of attraction for all concentrated knowledge, skills and abilities in the development of the road industry, within the framework of the development conditions established by the scientific and technological revolution. This takes into account synchronization of all efforts on the part of scientific communities and industrial partners. Today, the Siberian State Automobile and Highway University faces the task of transforming from an industry-specific university with an accumulated scientific base. It includes transport construction, into an entrepreneurial University with commercialization of scientific, technical and educational and results in the following areas: “Creation and testing of intelligent composite materials”; “Creation of automated complexes for modeling multicomponent new road materials, including those of technogenic soils”; “Informational modeling of road objects with data transmission system”; “New methods of road diagnostics and defect recognition”; “Digital control, monitoring, forecasting systems”; “Intelligent logistics and design of network road configurations, as well as the development and transfer of entrepreneurial competencies into educational сontent”. The specificity of training of engineers requires reaching a qualitatively new level, which makes it possible to enter the number of international recognized specialized universities, to solve ambitious tasks.

INFORMATION MODELING OF CONSTRUCTION OBJECTS: FEATURES OF APPLICATION AND DEVELOPMENT

The concept of database creation (modeling) of a building object (Building Information Model further – BIM) – an approach to erection, equipment, support, operation and repair of a building, which includes collection and complex processing during the design process of architectural, technological, economic and other information about the building under construction has been considered. The main advantages of BIM in construction have been highlighted. Advantages and practice of application of informational modeling of construction objects have been studied. Proposals to solve the problems that determine the further effective expansion of the practice of using information modeling of construction facilities have been formulated. In particular, these are modernization of existing and development of domestic software; transition to BIM technologies to public-private partnership facilities; consideration of the BIM model as the main data source for the partner relationship management system, expertise in architectural and urban planning decisions and the project declaration; development and application of intermediate (transitional) period procedure for application of BIM technologies - stages of assessment of readiness of participants of investment and construction complex for application of BIM technologies, application of mechanism of interaction between participants of investment and construction complex and active creation of new digital system of construction facility management.

Virtual Tours and Augmented Reality for Direct Data Integration

<p>The symptoms of overdue maintenance and underinvestment in historic infrastructure are ever-present in our society (rated with D+ by American Society of Civil Engineers, ASCE). To ensure the safety of historic and existing structures, on-site inspections are required, and structural health monitoring systems are frequently adopted. While these methods capture large amounts of information about a structure, there is not a comprehensive method for integrating these diverse datasets into a single, intuitive environment for both on- and off-site usage. The objective of this work is to explore two different methodologies for integrating datasets derived from the built environment. The first method, Virtual tours and informational modeling (VTIM), uses spherical panoramas to capture the interior and exterior of the built environment as well as enables a user to access data through on-click conditionals attached to the panoramas. The second method, Image-based documentation and augmented reality (IBDAR), uses a sparse point cloud to capture the built environment for on-site viewing and additionally stores an image at every annotation location to facilitate off-site viewing. Both methods are applied to case studies including a masonry lighthouse in Charleston, SC and a pedestrian bridge in Princeton, NJ. The advantages and disadvantages of each approach are discussed as well as steps for future work are briefly outlined.</p>
