Abstract Innovative technologies help automate the work of the designer. A 3D model of the building can be used to calculate the required values. This will also allow you to create associative sections that, when changing the geometry of the 3D model, automatically adjust the drawn elements on the resulting 2D drawing. Information technologies enable participants from all over the world to work on one project and, thanks to the BIM (building information modelling) method, to design buildings during their life cycle more efficiently. At present, critical studies are published on interoper-ability in BIM and its lack of coordination or amount of information that is misinterpreted, etc. However, working in BIM is the most effective way to use computer technology to design buildings. There is a lot of information about the building in the 3D model itself, which can also be used for purposes other than construction (building management, reconstruction). But how to process a large amount of information in a 3D model? Many buildings already have their 3D models shared on cloud platforms, these contain information that could help, for example, find solutions for green construction using artificial intelligence (AI). We meet with AI every day. It supports internet search engines, predicts auto-completion words as you type. AI can also be found in architecture – not only as visions at exhibitions, but also in research on process optimization in BIM.

2D Drawing

Building Information Modelling (BIM) is a major transformation in the construction industry. The construction is among the best solutions to overcome too many problems faced in the construction industry. Conventional construction is associated with two-dimensional (2D)  drawing technology while BIM used three-dimensional (3D) model and each component in the construction process contains detail information. Therefore this study is to collect the previous studies on the benefits of BIM in infrastructure from the perspective of the constructor to view the use of this method. The basic development of BIM for infrastructure is emphasized in this observation. Benefits for the constructor for BIM for infrastructure will be analysed from past research. Through this observation, we have found many benefits for construction on BIM for infrastructure. However, the listed benefits are the most stated in past research. These benefits show that this technology of BIM is the most effective method that been applied in the infrastructure construction industry.

3D models classification is a critical process of Building Information Modeling (BIM). A Deep Learning Approach is proposed to classify 3D models in BIM environment. The ray based feature extraction algorithm is used to extract features of 3D models and form features matrix. The Deep Belief Network constructed by Restricted Boltzmann Machines applies the features matrix and classifies the models adopting the effective training process. The process of training DBN is layer by layer. Experiments were taken on the public 3D model library of PSB model database. The results show that compared with several commonly used classification method, the proposed method of this paper has achieved good results in the 3D model classification for efficiently BIM.

In the Bridge project, design and analysis include two main components: preliminary design and detailed design, to integrate Building Information Modeling (BIM) in the design process of the Bridge. Firstly 3D modelling of the Bridge needs to be carried out, that means. It has transferred 2D drawing into 3D models. The BIM mainly focuses on modelling analysis, detection and feedback and design. Cantilever bridge construction is a step-by-step construction of a cantilever in segments and stitching them to segments previously casted by prestressing. When the cantilever segments are added to both sides of the pier, the bending moment in Bridge is negative & increases with the addition of each segment. While key blocks are added, the Bridge is converted from cantilever form to continuous form & the negative bending moment on the pier decreases. In this project, a bridge model of span 130 m has been designed and analysed in midas civil to observe the rate of change of Bending moment, reactions and deflections at different stages of construction in construction sequence and Service conditions.

3D Information

The development of methods for 3D data acquisition, together with progress in information technologies raises the question of creating and using 3D models and 3D information systems (IS) of historical sites and buildings. This paper presents the current state of the “Live Theatre” project. The theme of the project is the proposal and realisation of a 3D IS of the baroque theatre at Eeský Krumlov castle (UNESCO site).The project is divided into three main stages – creation of a 3D model, proposal of a conception for a 3D IS, and realisation of a functional prototype. 3D data was acquired by means of photogrammetric and surveying methods. An accurate 3D model (photo-realistic, textured) was built up with MicroStation CAD system. The proposal of a conception of a 3D IS was the main outcome of the author’s dissertation. The essential feature of the proposed conception is the creation of subsystems targeted on three spheres – management, research and presentation of the site. The functionality of each subsystem is connected with its related sphere; however, each subsystem uses the same database. The present stage of the project involves making a functional prototype (with sample data). During this stage we are working on several basic technological topics. At present we are concerned with 3D data, its formats, format conversions (e.g. DGN _ VRML) and its connection to other types of data. After that, we will be seeking a convenient technical solution based on network technologies (Internet) and an appropriate layout for the data (database). The project is being carried out in close co-operation with the administration of the castle and some other partners. This stage of the project will be completed in December 2005.A functional prototype and the information acquired by testing it will form the basis for the final proposal of a complex IS of a historical site. The final proposal and appropriate technology will be the outcome of the project. The realisation of a complex 3D IS will then follow. The results will be exploitable both for site management and for organisations working in the area of presenting historical sites and creating multimedia shows.

The Impact

<p><strong>Abstract.</strong> The implementation of Building Information Modelling (BIM) in each project, which is planned, have a design and construction stages. In the construction stage the objects are modelled by architects, engineers, and surveyors. Modelling process allowed to construct a BIM, which replaces two-dimensional (2D) building information into a three-dimensional (3D). Noticed that 3D BIM created by surveyors is not the same as 3D BIM, which is created by architects. Therefore, the purpose of this study is to identify the differences of the created 2D draftings made by 3D models between surveyors and architect’s. The surveyors make their model by using Unnamed Aerial Vehicle (UAV) system: Airborne Drone Data and Data photogrammetric processing technology. The 3D models accuracy is assessed by UAV images processing. The 3D information should be used to calculate façade geometry, volume, distances, contours, which are in the shadowed side of the house, and create 2D façade draftings. Traditionally, architects used 2D building’s façade draftings for pre-design in Construction Projects (CP). 3D architectural model is created by using structural 2D draftings created with Autodesk software. The architectural 3D model is more convenient for the general design and the visual view, it is easily to evaluate the impact of the changes that will be made. The 3D architectural model helps to finish a project at a low cost and also to evaluate the effect of the changes made. The 3D model from surveys measurements shows real view of an object (with deformations), meanwhile the 3D model from architects is a corrected image. Discrepancies between surveyors and architect’s 2D models made by 3D virtual reality (VR) are analysed in this article.</p>

3D Information

<p>Building information modeling (BIM) is a new technology in the bridge construction industry. 3D models can provide perfect numerical expression of drawings from design results. 3D information models for bridge structures improve design quality in terms of accurate drawings, constructability, and collaboration. However, there are lots of challenges to apply these techniques to actual bridge projects. For instance, bridge engineers are facing the challenge of making the vast information generated by their structural model useful for professionals further down the line in the lifecycle of the bridge. Contractors and inspectors require a 3D model which is created after the design process to add extra information related to activities and store that information in the same model. In this paper, technologies available to generate, manage, and enrich the bridge 3D model with intelligent information from construction to design and inspection are proposed.</p>

Building Information

Among 3D models, Building Information Models (BIM) can potentially support the integrated management of buildings’ physical and legal aspects in cadastres. However, there is not a systematic approach to author the cadastral information into the BIM models. Moreover, the common approaches for data validation only check the final cadastral output, and they ignore the data generation steps as potential avenues for validation. Therefore, this study aims to develop the criteria and standards to check the spatial consistency and integrity of BIM-based cadastral data in the process of generating the data. The paper utilises a case study approach as its methodology to investigate the requirements of generating a BIM-based cadastral model and identify the issues within the process. The results include a formative assessment (i.e., multistep validation approach during the data generation) alongside a summative assessment (i.e., one-step validation approach at the end of data generation). This study found the summative assessment alone insufficient for 3D cadastral data validation. The paper concludes that a formative and summative assessment together can improve the validity of the data. The results will potentially bring more efficiency to modern land administration processes by avoiding the accumulation of errors in 3D cadastral data generation.
