A study on schedule management for BIM projects in the construction industry

There is an advance modelling tool that currently been pushed by the industry is BIM. BIM as known as Building Modelling Information is a computerized process that is used to design, understand and establish the key physical and functional characteristic of a building on a ‘virtual’ computerized model basis at its most basic level [4]. Basically the resulting model is a digital representation of the building which the data can be extracted and analyzed to generate information that can be used for decision making and enhance the process of delivering the building and the entire life cycle use of the building [4]. BIM implementation can help to improve the quality of project especially the schedule management. By implementing BIM into construction project, it can provides schedule visualization which can make the construction planning more efficient. Besides that, through the BIM model clash detection can be detected in the preconstruction phase which save a lot of time on rework during construction phase

Integration of environmental data in BIM tool & linked building data

Environmental assessment is a critical need to ensure building sustainability. In order to enhance the sustainability of building, involved actors should be able to access and share not only information about the building but also data about products and especially their environmental assessment. Among several approaches that have been proposed to achieve that, semantic web technologies stand out from the crowd by their capabilities to share data and enhance interoperability in between the most heterogeneous systems. This paper presents the implementation of a method in which semantic web technologies and particularly Linked Data have been combined with Building Information Modelling (BIM) tools to foster building sustainability by introducing products with their environmental assessment in building data during the modelling phase. Based on Linked Building Data (LBD) vocabularies and environmental data, several ontologies have been generated in order to make both of them available as Resource Description Framework (RDF) graphs. A database access plugin has been developed and installed in a BIM tool. In that way, the LBD generated from the BIM tool contains, for each product a reference to its environmental assessment which is contained in a triplestore

BIM adoption and implementation for architectural practices

Severe issues about data acquisition and management arise during the design creation and development due to complexity, uncertainty and ambiguity. BIM (Building Information Modelling) is a tool for a team based lean design approach towards improved architectural practice across the supply chain. However, moving from a CAD (Computer Aided Design) approach to BIM (Building Information Modelling) represents a fundamental change for individual disciplines and the construction industry as a whole. Although BIM has been implemented by large practices, it is not widely used by SMEs (Small and Medium Sized Enterprises). Purpose: This paper aims to present a systematic approach for BIM implementation for Architectural SMEs at the organizational level Design/Methodology/Approach: The research is undertaken through a KTP (Knowledge transfer Partnership) project between the University of Salford and John McCall Architects (JMA) a SME based in Liverpool. The overall aim of the KTP is to develop lean design practice through BIM adoption. The BIM implementation approach uses a socio-technical view which does not only consider the implementation of technology but also considers the socio-cultural environment that provides the context for its implementation. The action research oriented qualitative and quantitative research is used for discovery, comparison, and experimentation as it provides �learning by doing�. Findings: The strategic approach to BIM adoption incorporated people, process and technology equally and led to capacity building through the improvements in process, technological infrastructure and upskilling of JMA staff to attain efficiency gains and competitive advantages. Originality/Value: This paper introduces a systematic approach for BIM adoption based on the action research philosophy and demonstrates a roadmap for BIM adoption at the operational level for SME companie

Building Information Modelling (BIM) standardization

BIM, short for Building Information Modelling, is a digital tool disrupting the construction industry as a platform for central integrated design, modelling, asset planning running and cooperation. It provides all stakeholders with a digital representation of a building's characteristics in its whole life-cycle and thereby holds out the promise of large efficiency gains. One particular area where standardisation on BIM is needed is the exchange of information between software applications used in the construction industry. The leading organisation in this domain is buldingSMART which has developed and maintains Industry Foundation Classes (IFCs) as a neutral and open specification for BIM data model. Other standardisation work include data dictionaries (International Framework for Dictionaries Libraries) and processes (data delivery manuals). ISO/TC 59/SC 13 "Organization of information about construction works", a subcommittee of the International Organization for Standardization (ISO) on the worldwide and CEN/TC 442 "Building Information Modelling", a technical committee of European Committee for Standardisation (CEN) on the European level develop and maintain standards in the BIM domain. Liaisons with a plethora of different institutions ensure the completeness and inclusiveness of the process as well as the smooth acceptance of adopted standards. Although BIM was originally devised for buildings the benefits such as less rework, fewer errors, enhanced collaboration, and design data that can ultimately be used to support operations, maintenance, and asset management mad it an attractive option also for infrastructure projects. As geographic information system (GIS) is a key element in any infrastructure project there is the need to integrate BIM and GIS. Both technologies use standard and open data formats, but they are different and presently there is no direct translation.JRC.E.4-Safety and Security of Building

Analysis Framework for the Interaction Between Lean Construction and Building Information Modelling

Building with Building Information Modelling (BIM) changes design and production processes. But can BIM be used to support process changes designed according to lean production and lean construction principles? To begin to answer this question we provide a conceptual analysis of the interaction of lean construction and BIM for improving construction. This was investigated by compiling a detailed listing of lean construction principles and BIM functionalities which are relevant from this perspective. These were drawn from a detailed literature survey. A research framework for analysis of the interaction between lean and BIM was then compiled. The goal of the framework is to both guide and stimulate research; as such, the approach adopted up to this point is constructive. Ongoing research has identified 55 such interactions, the majority of which show positive synergy between the two

Comparative analysis of technologies and methods for automatic construction of building information models for existing buildings

Building Information Modelling (BIM) provides an intelligent and parametric digital platform to support activities throughout the life-cycle of a building and has been used for new building construction projects nowadays. However, most existing buildings today do not have complete as-built information documents after the construction phase, nor existed meaningful BIM models. Despite the growing use of BIM models and the improvement in as-built records, missing or incomplete building information is still one of the main reasons for the low-level efficiency of building project management. Furthermore, as-built BIM modelling for existing buildings is considered to be a time-consuming process in real projects. Researchers have paid attention to systems and technologies for automated creation of as-built BIM models, but no system has achieved full automation yet. With the ultimate goal of developing a fully automated BIM model creation system, this paper summarises the state-of-the-art techniques and methods for creating as-built BIM models as the starting point, which include data capturing technologies, data processing technologies, object recognition approaches and creating as-built BIM models. Merits and limitations of each technology and method are evaluated based on intensive literature review. This paper also discusses key challenges and gaps remained unaddressed, which are identified through comparative analysis of technologies and methods currently available to support fully automated creation of as-built BIM models.published_or_final_versio

Architectural Information Modelling for Virtual Heritage Application

In today’s AEC industry (Architecture, Engineering and Construction industry), there has been a vast evolution in the usage of information and communication technology (ICT) for describing and managing construction projects. During the past years this led to the elaboration of the technique Building Information Modelling or BIM for describing buildings and building information according to their different composing elements. One of the major advantages in this BIM approach is the possibility to use this building information for calculation, simulation and analysis in related, more dedicated ICT applications. Starting from the building information model, these applications are accessible through an interoperability language, namely the Industry Foundation Classes (IFC), elaborated by the International Alliance for Interoperability or IAI. This paper proposes the development of an approach similar to BIM, namely Architectural Information Modelling (AIM), which describes more theoretical and historical building knowledge instead of the explicit and component-based descriptions inside BIM. It illustrates several possible advantages of this AIM approach for application in building documentation for virtual heritage, combined with possible historical analysis tools. It also makes a short comparison of this technique with procedural methods, a similar technique that is gaining much interest during the past few years in the domain of virtual heritage. Finally, this paper proposes future research ambitions and some conclusions of this first, conceptual research about an architectural information modelling approach

Does size matter? Experiences and perspectives of BIM implementation from large and SME construction contractors

This paper presents the findings of a qualitative study into the experiences and perspectives of large and SME construction contractors towards the implementation of Building Information Modelling (BIM) within their organisations. Results of the survey were statistically analysed to test for similarity and significant variations between the two groups. The results confirmed that both groups were equally aware of the perceived benefits of BIM, but found that the largest barriers to implementation were the costs associated with the technology and training requirements. Significant differences between the groups included plans to implement BIM and concerns with legal and commercial barriers

Building Information Modelling [BIM] for energy efficiency in housing refurbishments

Building Information modelling offers potential process and delivery improvements throughout the lifecycle of built assets. However, there is limited research in the use of BIM for energy efficiency in housing refurbishments. The UK has over 300,000 solid wall homes with very poor energy efficiency. A BIM based solution for the retrofit of solid wall housing using lean and collaborative improvement techniques will offer a cost effective, comprehensive solution that is less disruptive, reduces waste and increases accuracy, leading to high quality outcomes. The aim of this research is to develop a BIM based protocol supporting development of 'what if' scenarios in housing retrofits for high efficiency thermal improvements, aiming to reduce costs and disruption for users. The paper presents a literature review on the topic and discusses the research method for the research project (S-IMPLER)

Beyond the third dimension of BIM:A systematic review of literature and assessment of professional views

Across the world, the use of Building Information Modelling (BIM) and the three-dimensional (3D) model in projects are increasingly frequent for supporting design tasks. The digital data embodied in the BIM model is shared between the project stakeholders from the various disciplines. After giving an overview of the BIM 3D Model data used for planning (4D) and costing (5D), the study assesses the level of clarity or confusion on what the numbers of dimension refer to after the 5th dimension. A systematic review of the different BIM dimensions was conducted associated with an online questionnaire sent to various Architecture, Engineering and Construction stakeholders across Europe. The online questionnaire survey was limited to the 28 European Union (EU) countries. Each of the 28 EU countries was represented by at least one respondent. The research identified 52 papers considering BIM 4D Model, 15 considering 5D modelling, 6 considering the 6D Model and 2 considering the 7D. It was also identified a confusion between academics and practitioners for the 6D and 7D BIM dimensions. In fact, 86% of the professionals, actually using 6D, allocate Sustainability to 6D. Whereas 85% of the professionals using 7D allocate it to Facility Management.</p
