Successful management of the building design coordination process is critical to the efficient delivery of cost-effective and quality projects. Building information modeling (BIM) has had a significant impact on design coordination, supporting the identification and management of ‘clashes’ between building systems. However, many design coordination issues go beyond the traditional definition of a ‘clash’ and either go undetected or require further time, resources, and expertise to resolve. The goal of this research is to better understand the causes of coordination issues and the factors that affect their resolution. Specifically, we developed a taxonomy of design coordination issues and an ontology that defines the relationships between physical, process, and model-based design issues. We applied the taxonomy to two case studies and analyzed the frequency of issue types, the distribution of issue types across disciplines, and the resolution rates of issue types. We found that the m...
Conflict analysis in a BIM based design
2014
The development of an engineering design requires the participation of several parties involved in different disciplines, where each discipline conducts its own project in a somewhat disconnected manner from the remaining, therefore requiring project compatibility. In this context, an efficient conflict analysis between disciplines is essential to guarantee a well-developed design. The Building Information Modeling (BIM) methodology and tools associated with it present themselves as an excellent asset to support the process of conflict analysis, as they make it possible to merge all disciplines in an integrated virtual environment. The high level of detail and visualization provided by a BIM model leads to better collaboration between those involved throughout the design, hence resulting in a significant reduction of potential errors during the construction phase. The aim of the present study was to evaluate the practical capabilities of the BIM concept in the conflict analysis betw...
Based BIM techniques to clash detection for construction projects
Periodicals of Engineering and Natural Sciences (PEN), 2023
Building Information Modeling (BIM) has brought about a qualitative change in the design and management of construction projects because it represents a digital simulation of the physical characteristics of the building, and this increases its efficiency before the actual construction begins. In Iraq, most construction projects still use CAD two-dimensional drawing for the purpose of the implementation process, especially government projects, and this causes many problems due to the difficulty of communication between the various disciplines involved in the design and misunderstanding during implementation. This type of problem is reduced by combining BIM drawings prepared by designers and making them into a single model. In this process of merging conflicts are found using BIM tools such as Autodesk Navisworks. There are three main types of detection. This article includes how a clash detector can help improve clashes in the design phase before starting to construct a specific building using BIM applications and focuses on hard detection type (overlap of a particular element with the others). The methodology involved in this research is to study an educational building (24-classroom model school) consisting of structural and architectural BIM models only, clash detection analysis is done using Autodesk Revit and Autodesk Navisworks Manage software.
Design in construction has historically been conveyed by conventional 2D methods through the use of physical paper-based documentation either by hand by the architect and then engineer and other specialist designers, or later through the advent of computer aided design (CAD) technology prevalent in the 1990's. This 2D documentation, the result of both hand and CAD systems, has inherently been issued late due to the time to produce and uncoordinated due to the lack of integration with other design disciplines, and all this often in a very adversarial, contractual environment, often not taking into consideration the budget constraints and buildability issues and due to its 2D nature often does not address some of the 3D challenges posed by the project. There is also a very inefficient transfer of critical data during this process, particularly at the closure of a project at the development of the operation and maintenance manual and as built drawings. BIM as a tool helps to manage the overall processes much more efficiently by enhancing the flow of project information. Starting with the 'end in mind,' a client is now able to define his requirement in the form of an Employers Information Plan (EIP), to define the outputs requirement at handover. True BIM has its roots in a 'three dimensional (3D) virtual model' that is automatically linked to standard 2D documentation all within the same software environment. Models can be combined into a 'federated' model that can coordinate the structure and services of the building. The system's information or data is transparent and available to all stakeholders throughout the duration of the project. The 3D nature of the model can be used as a tool to promote better collaboration between the stakeholders in a less adversarial environment. All parties benefit from the use of BIM from the Employer to the Design Team to the Contractor and his Subcontractors. The designer benefits the most during the early design phase, whereas the contractor derives the most benefit during the construction phase. However, overall it is the Employer that benefits from the overall savings gained during the whole process if implementation correctly. Clients are increasingly requesting BIM services from construction managers, architects, and engineering firms as service to reduce schedule overruns, reduce cost overruns and success of company's capacity to finance virtual design and construction goals (VDC). Successful implementation of BIM can eliminate unnecessary cost and wastage due to design changes during the subsequent phases of construction process. BIM necessitates investment in software and training however returns on the investment (ROI) vary from project to project with right implementation strategy. Overall BIM ensures continuous performance and improvement by having effective and efficient collaboration amongst the stakeholders. Research has shown that there is a substantial cost saving impact through BIM implementation at all stages of the construction process (pre-construction, construction and operational stages).

The construction industry is one of the most unpredictable and human-dependent sectors of production. This is due to the large flow of information during construction, which requires clear organizational activities. Traditionally established methods of communication on construction sites require modernization. That is why the concept for practitioners "Building Description System and Construction Product Modeling" was developed in 1970. The building society supported this concept and called it "Building Information Modeling" - BIM. The new wave of digital design required a strong material and technical base, the analysis of existing documentation and the creation of design tools began. The authors of the article use the highly specialized NavisWorks software to analyze possible losses as a result of combining the existing design documentation into BIM models on the example of one of the Nur-Sultan projects. The residential complex located in Nur-Sultan was chosen...
Towards Automating Clash Management Process in Design Build Industrialized Projects
International Journal of Innovative Technology and Exploring Engineering, 2020
The Malaysian government has been promoting the use of industrialized building system (IBS) and Building Information Modeling (BIM) in the Productivity Thrust of the Construction Industry Transformation Program CITP2016-2020. However, the rate of BIM adaptation is hampered when the AEC industry still relies very much on traditional drawings and management practices. The clash management becomes one of the major problems affecting 25%-30% of contract value and 10% project cost. This study is part of a larger study aiming to propose an automated clash management system that supports integration of local IBS products in a BIM process. This paper reports the documentation of the underlying traditional practices for clash detection and resolution in industrialized projects. This study used case study research methodology involving a design-build construction team of an industrialized hospital project. In-depth interviews were conducted on the management team including the project manager, the architect, the coordinating engineer, and the quantity surveyor. Inductive logic approach was used to collect and analyze the data for this study. Results include documentation of the clash detection until resolution of management decision process through distinctive clash lifecycle phases including the sequential activities of the project management team and the criteria for decision-making. These results are expected to contribute towards proposing a technology-based clash management framework that would support the development of an automated clash management system. This paper extends the Discontinuity-in-Organization theory for supporting knowledge transfers in complex lifecycle process.
The construction industry of today's world is becoming more challenging and the projects, on the other hand, are becoming more complex than before. The projects in construction industry consume huge proportions of resources especially in-terms of financial resources. Malaysian construction industry is also no exception to this challenging environment. Different concepts and technology innovations have been developed to mitigate and rule out factors affecting the performance of the construction industry. Building Information Modeling is one of them (BIM). The BIM technology helps building in a virtual environment prior to physical construction. This objective of this study is to propose a model / frame work based on BIM technology which will allow reducing the potential adverse affects of delays, cost overrun, productivity, quality and other errors in the light of the available literature and past construction practices. The paper highlights the challenging issues like construction delays, claims, design changes, delayed approvals etc.
ROOT CAUSES OF CLASHES IN BUILDING INFORMATION MODELS
ABSTRACT Building Information Models (BIM) support designers and builders in creating and coordinating system designs and planning work. In practice���out of necessity���this includes checking that systems do not clash, but what constitutes a clash? How do clashes come about? Do clashes relate to design-, buildability-, or building-performance qualities? How does a clash detection process fit (or not) in lean project delivery? In this paper we describe our findings from research into clashes.
Minimizing conflicts during construction stage by using building information modeling
2015
Public Works Department of Malaysia (PWDM) is one of the main governments’ technical agency in Malaysia. PWDM has supervised numerous government projects but still faces problems such as delays and variations due to conflicts during construction. The main study is to investigate the effectiveness of applying Building Information Modeling (BIM) in managing conflicts during construction. The results of the analysis were established from surveys of questionnaires, interviews and lastly from PWDM’s own database. The analysis was based on mixed method which combines the qualitative and quantitative analysis approach and finally comparing it with literatures that discusses conventional projects and projects using BIM. This study which focuses on the conflicts during construction, finds that conflicts are attributed to the lack of communication and coordination which eventually contributes to the project delay. This study was conducted in order to find the root cause of the problem and pro...
Mitigating Disputes and Managing Legal Issues in the Era of Building Information Modelling
Journal of Construction in Developing Countries, 2021
Construction disputes are inevitable. They often arise between project stakeholders for numerous reasons and to resolve them, construction professionals adopt various dispute resolution methodologies. This study aims to identify the role of building information modelling (BIM) in mitigating such disputes and addresses the legal barriers faced by the architecture, engineering and construction (AEC) industry while adopting BIM. The study reveals that disputes can be mitigated and managed efficiently with the intervention of BIM, as BIM offers various designing, planning, estimating, collaborating and controlling features. The benefits of BIM are impressive and exceptional; however, it comes with some legal issues that are first clarified and addressed with the support of a literature review and later validated through interviews with industry professionals. Dispute resolution, contractual arrangements, design responsibility, intellectual property (IP) rights and a lack of standardisation are identified as substantial concerns when adopting BIM. Thus, a strategy is proposed to manage these legal issues that entail the adoption of the appropriate contract suite, the formation of a common data environment (CDE) and the establishment of a firm BIM execution plan (BEP). Workshops, training sessions and seminars are also recommended to educate the industry with BIM features as it brings about the second revolution in the AEC industry.
