How does building information modeling influence decision-making process in the project design? An input, process and output analysis

Decision-making is critical throughout the entire project cycle, particularly during the project design stage, where the detailed concept is developed based on stakeholders' requirements and project constraints. To improve project design, various digital technologies are employed to provide stakeholders with comprehensive data for informed decision-making. The paper aims to understand how BIM influence the decision-making process – input, decision and output - during the project design. More specifically, we aim to answer the following question: which decision-making challenges could restrict BIM benefits during the project design stage? Utilizing two embedded case studies and a focus group, we explore the perceived benefits and challenges of BIM in decision-making among project actors. This research contributes to the field of digital technologies in project management by highlighting specific benefits and challenges, such as decision validation and the transformation of decision makers’ roles. Our findings illustrate the interconnected nature of these benefits and challenges through the Input-Process-Output model. We specifically emphasize that the advantages of BIM in the decision-making process can be significantly affected if project organizations do not adapt the roles and competencies of decision makers to effectively utilize BIM. The use of BIM therefore brings novel decision-making challenges, which are presented in the discussion.

The use of BIM involves making several project stages compatible, with precise detailing and checking construction interferences, thus facilitating the execution of the work and increasing the client's reliability through efficiency and transparency. Therefore, this work consists of analyzing the BIM implementation process, identifying motivating factors, difficulties and changes in project practices. As a parameter for analyzing the objectives, the methodology was based on a case study together with an engineering office working mainly in public projects. With this, it was observed that understanding BIM and continuous training are crucial for efficiency and competitiveness in the market, highlighting the importance of cultural transformation within companies for the successful adoption of this methodology.

Comparative Analysis of Conventional Methods with BIM Methods on Construction Cost Estimate at Structure Project Design Calculations (Case Study of Construction of A Satpol PP Building)

Construction cost estimate in construction projects requires high accuracy in calculating work volumes and applying unit cost analysis. Lack of accuracy in calculating the volume of work can result in inaccurate cost estimates, causing project budget overruns. This research discusses the use of 3D BIM planning concepts using Autodesk Revit software to help calculate volumes accurately, with the aim of reducing project budget overruns. Comparative analysis of cost estimates between the use of Autodesk Revit and conventional methods provides an overview of the efficiency and effectiveness of using BIM software in estimating construction project costs. The object of this research is the Satpol PP Bantul office construction project, with a focus on structural work. This research method includes data collection, 3D BIM modeling, calculating cost estimates based on the volume produced using unit cost analysis, and comparative analysis of cost estimates between the use of BIM software and conventional methods. Based on the research results, it found that the construction cost estimate for structural work from Revit had a value of IDR 862,330,518.59 and a difference of IDR 53,420,195.31. This shows that the use of the 3D BIM concept results in 5.83% cheaper calculations than conventional construction cost estimate methods.

Parametric detailing of structural walls in reinforced concrete using revit software

The use of BIM has become increasingly important in the development of civil construction and architectural projects. The methodology integrates various design stages and allows for compatibility between different software. The parameterization process in Revit, a software used for architectural design, was researched to assist professionals in creating projects using reinforced concrete structural walls. These walls are flat elements with welded screens as reinforcements to resist structural stresses. The objective of the research was to model and parameterize a wall with an opening and a monolithic model. Firstly, data about the norms and characteristics of structural walls used in Brazil was collected, and technical drawings were produced using AutoCAD. This was done to recognize the parameters that would be used in Revit while modeling. Finally, the parameterization process was initiated using Revit functionalities to model the concrete wall and insert the necessary reinforcement using the "rebar" tool that the software offers. Technical drawings such as plans and cuts were produced from these models, which showed the sections of concrete and steel elements. Automated quantitative data was also obtained.

Analysis and Evaluation of PointNet for Indoor Office Point Cloud Semantic Segmentation

Indoor modeling is one of the primary sources of information in building management due to the increased use of BIM in the AEC industry. The indoor model can be acquired with several survey instruments, but TLS is the most popular resulting point cloud that can be processed into a 3D model. However, the process commonly still uses inefficient manual methods. Point cloud data have irregular, unordered, unstructured characteristics, making them more challenging to process. The deep learning algorithm can be a solution to solve the problem. PointNet is the first deep learning algorithm that directly accepts point cloud data as input. This study aims to analyze and evaluate the office indoor point cloud segmentation using PointNet. The office indoor point cloud data was acquired using TLS and then pre-processed for deep learning input. Transfer learning strategy is used as a weight initialization technique. The pre-trained model was trained with the S3DIS dataset and then fine-tuned to segment nine indoor classes in this study. The result shows PointNet achieves 85% overall accuracy and 66% average class IoU score to predict indoor classes using this study’s point cloud data. Geometry control shows that the predicted point cloud has an RMSE score of 1.8 cm, meaning the geometries of the segmented point cloud are accurate. Using the transfer learning method has increased the performance of the deep learning model. Further research is needed to evaluate the model thoroughly using more training and evaluation data and different transfer learning strategies.

A Review on Adoption of Bim in Reducing Construction Rework

In the construction industry, the aim of project control is to ensure that the projects are completed on time, within budget and achieving other project objectives .Rework is one of the most major problems in the construction industry. It has an impact on time, cost, quality, and practically every other project success factor. There is always a significant loss of resources, materials, investments, and workforce-time as a result of rework and poor use of resources and materials in the works. Rework may be reduced by designing and planning with full understanding of customers and stakeholders, good communication amongst project aspects, applying quality management systems, and utilizing Information Technology. Because of the worldwide expansion of IT and the widespread use of BIM ,which coordinates all of the software and parts of the construction--the appearance of mistakes and inconsistencies has been drastically reduced in recent years, allowing specialists to realize their full potential in doing projects. To the best of the author’s knowledge, this study is to use actual project data to measure the effects of BIM implementation on rework in construction projects. The study's findings enable practitioners to develop techniques to reduce rework with BIM implementation, enhance project cost and time performance, and increase project delivery efficiency

Energy Efficient Design for a Conventional Building using BIM Tools

Nowadays, energy has become a key player in the AEC industry because of the increase in global warming and energy crisis. Due to global warming the consumption of energy has increased enormously in buildings. The no. of buildings have grown in tandem with rise in levels of urbanization in developing & developed countries, which in return rises the bar for energy consumption. The improved energy performance of the building is significantly influenced by both interior and exterior building factors. It is preferred to perform energy analysis in the design stage of the building. The current paper is the talks about the energy model by improving the design of a conventional buildings, an energy – efficient model is been created which uses less energy and reduces its carbon footprint. Energy analysis using BIM can be used to optimize the building’s design and identify opportunities for improvement, such as implementing energy-saving technologies, improving insulation and air tightness, and reducing energy loss through window frames, it’s glazing type and also redesigning the other parameters including HVAC types, Window shades, change in orientation etc. In the earlier, the conventional model to produce energy through renewable sources like solar and wind, and incorporate them into the building’s design. Thus, obtained results after analysis can be used to take design decisions and ensure the building meets energy efficiency standards and sustainability goals. The use of BIM in the design and analysis of energy-efficient buildings can help support the transition to a low-carbon, sustainable future.

Automation of escape route analysis for BIM-based building code checking

The use of BIM is becoming increasingly important in the AEC industry because the included dataset enables the automation of many processes. One emerging application of BIM is the automation of building code checking by building authorities. Building code checking is a time-consuming process, particularly for escape routes. Therefore, its automation promises considerable optimisation potential. This study presents a semi-automated escape route analysis for building code checking. Our developed concept consists of two automated steps, with a legally required manual step in between: (1) escape route generation, which provides possible routes from which designers can select a valid combination, and (2) escape route validation, which checks the selected combination of escape routes for validity. The basis of both automated steps is a novel indoor navigation model. We implemented the concept in Solibri Office and validated it with real-world models. The developed escape route analysis method shows potential to improve designers’ escape route planning and building authorities’ escape route checking.

BIM USE IN GREEN BUILDING CERTIFICATION PROCESSES

Green building certification schemes have been developed to incentivize sustainable construction leading to the development of green BIM technology, which uses multi-disciplinary data to support sustainable construction. However, due to a lack of understanding, interoperability, and technical issues, BIM is not widely used to support green building certification. This study investigates the current use of BIM for certification purposes, the building characteristics or information that need to be modeled, and the skills or knowledge required to use BIM for green building certification. The research, which employed a case study approach, examined the BIM use in a recently built 6 Green Star rated Head Office of a major supermarket chain in south Auckland. The main data collection methods were document analysis and semi-structured interviews with key project stakeholders. The results suggest that despite generally good knowledge of BIM and sustainable building design, the connection between BIM and green building certification is weak or non-existent. Instead, BIM is used mainly for model authoring, coordination, quantity take-off, and basic sustainability analysis. The main factors hindering BIM integration that have been identified are low-quality modeling, lack of multi-disciplinary coordination, and inefficient procurement. It is recommended that BIM usage should be accurately detailed and coordinated for downstream uses to gain the most value. Procurement should also accommodate appropriate BIM procedures to encourage multi-disciplinary coordination. Furthermore, new technology and research development are also needed to increase interoperability with sustainable (green) software.

A SEMI-AUTOMATED APPROACH TO MODEL ARCHITECTURAL ELEMENTS IN SCAN-TO-BIM PROCESSES

Abstract. In the last years, the AEC (Architecture, Engineering and Construction) domain has exponentially increased the use of BIM and HBIM models for several applications, such as planning renovation and restoration, building maintenance, cost managing, or structural/energetic retrofit design. However, obtaining detailed as-built BIM models is a demanding and time-consuming process. Especially in historical contexts, many different and complex architectural elements need to be carefully and manually modelled. Meshes or surfaces and NURBS or polylines, derived from 3D reality-based data, are recently used as a reference for the HBIM accurate modelling. This work proposes a comprehensive and novel semi-automated approach to reconstruct architectural elements through the Visual Programming Language (VPL) Dynamo software and a Boundary-Representation method (B-rep), starting from 3D surveying data and point clouds classification. A wide package of scripts provides solutions for modelling complex shapes and transferring the obtained 3D models into BIM Authoring tools for a complete reconstruction phase. The presented procedure, useful for different BIM or HBIM applications, proved to reduce the modelling time significantly.

The Effectiveness of Utilising the Building Information Modelling Based Tools for Safety Training and Job Hazard İdentification

The fields of architecture, engineering and construction (AEC) have kept pace with recent technological developments in design and construction. However, it is difficult to obtain information on the breadth of applications of BIM -based tools throughout the life cycle of construction projects. Hence, this study attempts to empirically identify and evaluate the applications of pre-construction tools, with a focus on safety training and workplace hazard recognition. A questionnaire in the form of a survey was used to collect data. The results show that the ten predictors account for 52.3% of the variation in BIM knowledge (F (10, 56) = 6.133, p < 0.001).It is also found that site analysis and safety instructions have no effect on the measured variable. The study represented a comprehensive blend of research to improve the use of BIM -based tools for safety training and workplace hazard identification. It also contributed to the knowledge of how to use BIM -based tools in the pre-construction phase. The development of the BIM -process flow framework for safety training and hazard identification will be the main focus of future work.

Augmented Reality for Building Authorities: A Use Case Study in Austria

The widespread usage of BIM and technological advances in augmented reality (AR) paves the way for Construction 4.0. This digital transformation has reached the construction industry and requires consideration of all life cycle phases. The approval phase has been little researched to date. In Vienna, the analogous process takes up to 18 months. This long duration inhibits progress in the building industry. One reason for this is objections from parties who are nonexperts and have difficulty understanding the project solely from its 2D plans. Therefore, the City of Vienna wants to redesign the building authority processes through the use of BIM and AR in the BRISE-Vienna research project. This article examines possible applications for public authorities. AR can be utilised at the interface between authorities and stakeholders and is intended to accelerate processes through better communication. For the City of Vienna, 12 AR use cases were developed from process analyses and expert interviews. In addition to the conception of the AR use cases for public authorities, a study was carried out regarding their benefits and feasibility. The use cases have the potential to increase the understanding of the project for experts and nonexperts. The best-rated AR use cases (plan checking and hearing during the permission process) will be further developed in the research project. The AR use cases should help to significantly accelerate processes in Vienna and, thus, serve as a basis for other cities and countries.

BIM model to support O&M tasks

Technological evolution and BIM have changed the design development process in the construction industry. The operation and maintenance (O&M) phase requires building information throughout its service life, which was previously paper based, making it difficult to carry out maintenance activities. BIM assists in the management, storage, and digital sharing of information generated. However, only part of the information generated is required for the maintenance phase of the building. Although a subset of the IFC schema already exists to describe the data exchange between the BIM model and maintenance software, the data are generic and not well defined according to each the element source of maintenance (ESM). Therefore, through a literature review of existing studies on the use of BIM to support O&M processes, this paper aims to design an information flow to integrate maintenance information into the BIM model. The information is based on six main maintenance acts (inspection, cleaning, proactive measure, correction, replacement, and terms of use) and organized in an external sheet. The building will be divided into ESM according to its function in the building to facilitate the maintenance information flow between sheets and the BIM model.

BIM-BASED PROTOTYPE OF A MATHEMATICAL MODEL OF CONSTRUCTION PLANNING

This article tackles the problem of rational and effective planning of the entire construction site, including the planning of mechanisms, equipment, warehouse space, temporary buildings, temporary engineering networks, etc. The authors propose the principles of creating a mathematical model to calculate the needs of construction objects, using the photogrammetry model. The problems raised can be solved with the use of BIM in the preparation for construction planning stage. The prototype mathematical model presented in this article addresses these issues: identify current situation, using photogrammetry model, define optimal number and location of construction site objects, avoid conflicts between cranes, detect possible hoisting problem, avoid overload of cranes, and of course construction site planning. Therefore, it becomes possible to perform a multicriteria decision-making analysis. Extensive analysis in the pre-construction stage is often abandoned due to the lack of data on the current situation, difficult calculations of the need for mechanisms, equipment and simply due to the lack of time to analyze all possible rational solutions. The data received from the created mathematical prototype could also be used in further construction stages for planning human and material resources, the project schedule and cost estimate.
