Sufficiency of Technology Adaptation in Risk Monitoring Criteria for Heritage Sites Management in Malaysia: Site-Based Classification

This paper presents an endeavour of integration of GIS (Geographical Information System) and BIM (Building Information Modelling) for indoor geovisual analytics. The merits of two types of technologies, GIS and BIM are firstly analysed in the context of indoor environment. GIS has well-developed capabilities of spatial analysis such as network analysis, while BIM has the advantages for indoor 3D modelling and dynamic simulation. This paper firstly investigates the important aspects for integrating GIS and BIM. Different data standards and formats such as the IFC (Industry Foundation Classes) and GML (Geography Markup Language) are discussed. Their merits and limitations in data transformation between GIS and BIM are analysed in terms of semantic and geometric information. An optimized approach for data exchange between GIS and BIM datasets is then proposed. After that, a strategy of using BIM for 3D indoor modelling, GIS for spatial analysis, and BIM again for visualization and dynamic simulation of the analysis results is presented. Based on the developments, this paper selects a typical problem, optimized indoor emergency evacuation, to demonstrate the integration of GIS and BIM for indoor geovisual analytics. The block Z of the Hong Kong Polytechnic University is selected as a test site. Detailed indoor and outdoor 3D models of the block Z are created using a BIM software Revit. The 3D models are transferred to a GIS software ArcGIS to carry out spatial analysis. Optimized evacuation plans considering dynamic constraints are generated based on network analysis in ArcGIS assuming there is a fire accident inside the building. The analysis results are then transferred back to BIM software for visualization and dynamic simulation. The developed methods and results are of significance to facilitate future development of GIS and BIM integrated solutions in various applications.

Collaboration is essential to achieve project targets and minimising rework in any project including railway projects. The railway project is considered as a megaproject that requires effective collaboration in order to achieve efficiency and effectiveness. To ensure that the railway continues to provide safe, reliable, cost-effective services, and remains environmentally friendly while driving economic growth, engaging new technologies and new types of work models are required. Among these technologies, Building Information Modelling (BIM) and Geographic Information Systems (GIS) are recent technologies that support collaboration. However, using these technologies to achieve effective collaboration is challenging, especially in railway projects as they are amongst the most complicated projects and often numerous parties are involved in making important decisions. Currently, there is a lack of evidence-based guidelines or processes for effective collaboration in railway projects throughout their design stage. Therefore, this thesis has focused on developing a process model to improve collaboration in the design stage of railway projects using BIM and GIS. This research adopted a mixed-methods approach to examine and identify the issues that hinder collaboration in railway projects to assist in developing theBIM and GIS-enabled collaboration process model. An online questionnaire was designed and distributed to professionals to assess the state-of-the-art in BIM and GIS followed by two rounds of in-depth interviews with experts. The first round aimed to identify collaboration issues and consisted of 15 in-depth, face to face and videoconference/telephone interviews; while the second round consisted of 10 in-depth interviews to identify the process model components of the collaborative process using IDEF technique.The questionnaire data were analysed using descriptive statistics and statistical tests (for example, Regression analysis, Wilcoxon Signed Ranks and Kruskal-Wallis Test). The results showed a lack of training in BIM and GIS and identified collaboration as a significant factor for railway projects, but there were many challenges to achieve effective collaboration. These challenges have been further investigated during the first round of interviews using content and thematic analysis. The results revealed that the most common challenges were getting the right information at the right time for the right purposes followed by resistance to change. Furthermore, the findings indicated that developing a process model, based on a clear plan of work demonstrating the collaboration process, is a potential solution to tackle these challenges. Thus, a Collaborative Plan of Work (CPW) has been developed through combining the RIBA (Royal Institute of British Architects) Plan of Work and the GRIP (Governance for Railway Investment Projects) stages. This CPW will be the basis to develop a process model for BIM and GIS-enabled collaboration. The results from the second round of the interviews identified the process model components which are: key players’ roles and responsibilities, tasks (BIM and GIS Uses), BIM and GIS-based deliverables, and critical decision points for collaborative process design. Moreover, this process model was formulated utilising Integrated DEFinition (IDEF) structured diagramming techniques (IDEF0 and IDEF3).In conclusion, the process model of the collaboration process and the integrated implementation of BIM and GIS sets out role and responsibilities, deliverables, and key decision points. Finally, the research outcomes have been validated through a focus group and interviews with professionals in the biggest Railway company where the proposed process model was operationalised using a commercial Common Data Environment platform (viewpoint 4project). From their discussion, feedback and recommendations the IDEF processes model have been refined. It is concluded that such a process is crucial for effective collaboration in railway projects as it enables the management of the design process in terms of technologies used, activities, deliverables, and decision points. Therefore, the research findings support the notion that BIM and GIS can help to achieve effective collaboration by delivering the right information at the right time for the right purposes. As a result, they help to achieve the projects’ objectives efficiently in terms of time, cost and effort.

Building Information Modeling (BIM) is a technology that focusing on the building element properties to the construction components which cover the interior and exterior building, while Geographic Information System (GIS) describe to the technology that can provide the large-scale information which cover inside and outside buildings (spaces and areas). In construction project application, BIM technology already been used as a worldwide tool while GIS rarely been applied. Each technology contains their own advantages that can be utilized in the construction project application. To bring the best effective approach in construction project, the integration between BIM and GIS technology can be considered. This paper presented an attempt in integrating BIM and GIS by using FME as a data integration platform to solve the limitation of BIM in construction project by using advantages of GIS. Through this research, an investigation of the data exchange during integration process between BIM and GIS will be look up. By using this approach, it is possible to store the BIM and GIS data in one environment. The end results for this paper will cover the method of the data exchange between BIM to GIS and GIS to BIM. Besides that, this paper highlight how GIS can solve the limitation in BIM in construction project.

Conservation Management Plan (CMP) and its implementation is a relatively new practice in the protection and safeguarding of heritage buildings and sites in Malaysia. The CMP is a vital legal document which details out the management strategy for historic assets, heritage sites and significant places; as well as prescribes future use, management, alteration, or repair to retain the significance of heritage buildings and sites. Without proper CMP implementation, gazetted heritage buildings or sites are at risk due to potential development threats that may affect their significant values. This article presents the fundamentals of the CMP as stated under the Malaysian laws, which are the National Heritage Act 2005 (Act 645), State of Penang Heritage Enactment 2011 (Enactment 14) and Sarawak Heritage Ordinance 2019 (Chapter 77). This study involves a qualitative research in examining provisions in the Malaysian heritage laws; as well as reviewing the contents of the CMP of Brooke Dockyard in Kuching, Sarawak as a case study. The study found that all three Malaysia heritage laws have similar provisions in aspects of authority, power, control, management, and designated criteria for heritage property. Specific provisions of the Sarawak Heritage Ordinance 2019 (Chapter 77) laws were found to be fully complied and well documented in the case study of the CMP of Brooke Dockyard. Hence, the CMP of Brooke Dockyard serves as an instrumental tool in safeguarding the significant values of this heritage building prior to its transformation into a maritime museum. The CMP provides guidance to envisage future care and use of Brooke Dockyard including new development proposals within the designated core and buffer zones. The CMP also portrays Brooke Dockyard as one of the significant heritage sites in Sarawak that should be conserved for the benefits of future generations.

Building information modelling has emerged to address the issues associated with information integration and interoperability in the architectural, engineering and construction (AEC) industry. Today, building information models (BIMs) have become capable of representing detailed geometrical and semantic information about building elements. On the other hand, some urban management tasks, such as disaster management, delivery of goods and services, and cityscape visualization, are managed by using a geographic information system (GIS) as the current state-of-the-art system, as these tasks require a high level and volume of integrated geospatial information. Several of these tasks, such as fire response management, also require detailed geometrical and semantic information about buildings in order to become facilitated through better automation. In this context, this paper first presents an approach proposed for integrating building and geospatial information models and later presents a fire response management case where the integration approach is implemented. The paper starts with a summary of the background on building information modelling and the role of GIS in fire response management before providing an introduction to the software systems integration and the concept of integrated data layers. The paper then explains the integrated data layers approach proposed during the research and the implementation of the approach in the domain of fire response management. The research results confirmed that the proposed approach is applicable in the domain of fire response management and further investigation demonstrated that the use of BIMs as part of an integrated data layer enables the fire response management process to be facilitated through better automation.

ABSTRACTThe integration of Building Information Modelling (BIM) and geographic information systems (GIS) is a promising but challenging topic to solve problems in construction industry. However, loading and rendering rich BIM geometric data and large-scale GIS spatial information in a unified system is still technologically challenging. Current efforts mainly simplify the geometry in BIM models, or convert BIM geometric data to a lower level of detail (LOD). By noticing that only exterior features of BIM models are visible from outdoor observation points, culling BIM interior facilities can dramatically reduce the computational burden when visualizing BIM models in GIS. This study explores the outline detection problem and presents the OutDet algorithm, which selects representative observation points, transforms & projects the BIM geometric data into the same coordinate system, and detects the visible facilities. Empirical study results show that OutDet can cull a large portion of unnecessary features when rendering BIM models in GIS. The use of outlines of BIM models is not an alternative but rather a supplementary approach for current solutions. Jointly using LOD and outer surface can help improve the efficiency of integrated BIM-GIS visualization.Because OutDet retains BIM geometry and semantics, it can be applied to more BIM-GIS applications..

Abstract. Application of Building Information Modeling (BIM) in construction industry has been applied for many years back. This because BIM can provide a better advantage in construction industry in term of controlling and managing construction project during their life cycle. The advantages that can be provide by BIM is focusing on the indoor planning tasks. But, when the construction project involves, besides indoor planning, outdoor planning also is important part that need to be look up. To cover the outdoor planning in construction project, Geographic Information System (GIS) need to be applied. GIS can overcome this problem because GIS mainly for outdoor planning by using their spatial analysis. GIS can offer a high degree of geospatial information and can provide the detailed geometrical and semantic information of building to assisted across improve automation. Towards produce the improved preparation in construction project, BIM and GIS should be integrated. To integrate both domains, the data interoperability between them need to be investigate because they used different data standard. This study focusses on solving the data interoperability through the data integration between BIM and GIS to solve the problem of data mismatch and data missing during data translation process. Industry Foundation Classes (IFC) was used as a data standard to perform the data integration between BIM and GIS. The outcomes from this study show that when the data interoperability applied between BIM and GIS, the problem above can be solved, and the data dimension and their coordinate system also can be control.

In order to improve communication on a construction site, this research focuses on the use of Building Information Modeling (BIM) in site management for material and progress control in Hong Kong. Components of site management as well as the suitable aspects of applying BIM in site management were identified. Case studies of BIM implementation on two construction projects were presented. Interviews were arranged with BIM professionals, including consultants and contractors. The limitations of adopting BIM on site management were also analyzed. The results and analysis showed that the application of BIM in material and progress control was mainly for quantity takeoff, construction sequence optimization and provision of knowledge database. This database encouraged interaction between parties because an informative BIM model could not be produced by just one party. The findings show that the visualization from BIM 3D/4D model helps engineers or planners to become more confident about real happenings on the construction site. It can also help to identify and resolve the material and progress control related problems before construction commences.

For many years, the objective of spatial databases created using Geographic Information System (GIS) technology was to provide information about large spaces and areas outside of buildings. Building Information Modeling (BIM) technology focused mainly on small spaces, indoor and outdoor, targeted at other users and slightly different applications, was developed simultaneously for several dozen years. The significant development of GIS technology and new tools for quick data acquisition (e.g., laser scanning) and growing user needs resulted in the geoinformation modeling of the space inside buildings as well. BIM, on the other hand, began to be used for increasingly larger spaces outside buildings. Technology developers, users, and scientists started to notice that works turned out to be repetitive and that combining two different technologies is necessary; however, it is not simple. The research presented in the article is another attempt at connecting the world of BIM and GIS. The proposed integrated database environment of BIM/GIS spatial data makes it possible to store GIS and BIM data, enabling the use of the same data by both types of systems simultaneously and in a consistent manner. This allows BIM systems to to obtain simultaneous access to BIM and GIS data, which may be needed in, for example, the process of analyzing a building and its immediate surroundings. At the same time, GIS can obtain up-to-date building data necessary for spatial analyses, building management, or route mapping in navigation applications. The concept proposed in this article assumes a pragmatic approach, which is based on sharing Industry Foundation Classes (IFC) and CityGML schemas from a single database for BIM and GIS applications in their practically original form using an additional integrated BIM-GIS schema, called BIGI-S. The research joins some other works in this field, complementing them and adding a new perspective. This paper describes the concept of this solution, including specific data structures, data conversion algorithms, and a prototype solution. The tests carried out by the authors prove the robustness of the adopted concept and its technical feasibility.

<p>The use of Building Information Modeling (BIM) is certainly increasing, especially in the field of Civil Engineering and Architecture. In recent years, research for new solutions has focused on the integration of BIM and GIS (Geographic Information System), referred to as GeoBIM. Most applications focus on issues related to the import and interoperability of BIM data into a GIS environment and vice versa. Data integration in a well-designed GeoBIM should address the following aspects: i) data harmonization and consistency (e.g., accuracy estimation, geometric and semantic representation, amount of detail, geo-referencing); ii) interoperability of data coming from different sources; iii) transformation of a set of data into a standardized format. One of the most evident inconsistencies if working with BIM or GIS is in the georeferencing of data: BIM designers work in a local Cartesian system while the terrain morphology is referred to a Geodetic Reference System, in the case of Europe, and therefore also for Italy, such system is the ETRS89, realization ETRF2000. The objective of this work is to achieve a true integration between BIM and GIS through the use and combination of the strengths of both technologies: the semantic and spatial component of GIS with the 3D and detailed information coming from the BIM model. A model that meets these requirements will allow a management of the structure and / or infrastructure in a wider and more complete context; therefore, not only at the local level but will be applicable to structures that have a strong impact with the territory and located in areas subject to hydrogeological risk. One of the innovative aspects of the study is the integration of the regional Topographic Database (TDB) with the altimetric component extracted automatically from LiDAR data; the process aims to allow the reconstruction of the volumes in an automated way of each object to define the 3D spatial attribute for the purposes of three-dimensional modeling. The study area is located near the “Monti Lattari” in the Campania Region, in southern Italy. The whole area consists of areas exposed to high hydrogeological risk, characterized by the presence of a complex infrastructural network (railway, highway, national and provincial roads), rich in viaducts, tunnels and galleries. In details, the GeoBIM model of a viaduct (Olivieri Viaduct), built between the years ‘50 and ‘60, has been made. The main structure is a Maillart-arch-type bridge, made of reinforced concrete with a continuous frame deck and two access viaducts. The structural model has been generated from the point cloud acquired by Terrestrial Laser Scanner (TLS). The BIM model has been realized by using Revit software package (Autodesk), which allowed to organize the information useful to define the entire viaduct: each virtual element has been “informed” with all the parameters and characteristics of the structural elements. The next work phase was addressed to the design of a workflow able to combine the BIM model into a GIS developed by using ESRI tools. So, the parametric model produced in Revit is transformed into a GeoDatabase.</p>

Building Information Modeling (BIM) has become increasingly popular in the construction industry as a way to enhance risk management. However, little attention has been paid to the challenges of using BIM for safety management in Malaysia’s oil and gas construction sector, which is particularly hazardous and requires effective safety management to complete projects successfully. This study aims to identify the obstacles to using BIM for safety management in Malaysia’s oil and gas construction sector and to understand the root causes of resistance to its adoption. Exploratory factor analysis and structural equation modeling were conducted on survey data collected from industry professionals. The study found that knowledge obstacles, creative hurdles, technical barriers, supervisory barriers, and functional barriers are the most significant challenges hindering the widespread adoption of BIM for safety management. These challenges were confirmed to significantly affect BIM adoption for safety management. The study’s findings have important implications for policymakers, industry practitioners, and academics seeking to improve safety management in Malaysia’s oil and gas construction sector through the use of BIM. Future research could explore additional variables that may impact BIM adoption for safety management in this sector.

In recent years, 3D virtual indoor/outdoor urban modelling becomes a key spatial information framework for many civil and engineering applications such as evacuation planning, emergency and facility management. For accomplishing such sophisticate decision tasks, there is a large demands for building multi-scale and multi-sourced 3D urban models. Currently, Building Information Model (BIM) and Geographical Information Systems (GIS) are broadly used as the modelling sources. However, data sharing and exchanging information between two modelling domains is still a huge challenge; while the syntactic or semantic approaches do not fully provide exchanging of rich semantic and geometric information of BIM into GIS or vice-versa. This paper proposes a novel approach for integrating BIM and GIS using semantic web technologies and Resources Description Framework (RDF) graphs. The novelty of the proposed solution comes from the benefits of integrating BIM and GIS technologies into one unified model, so-called Integrated Geospatial Information Model (IGIM). The proposed approach consists of three main modules: BIM-RDF and GIS-RDF graphs construction, integrating of two RDF graphs, and query of information through IGIM-RDF graph using SPARQL. The IGIM generates queries from both the BIM and GIS RDF graphs resulting a semantically integrated model with entities representing both BIM classes and GIS feature objects with respect to the target-client application. The linkage between BIM-RDF and GIS-RDF is achieved through SPARQL endpoints and defined by a query using set of datasets and entity classes with complementary properties, relationships and geometries. To validate the proposed approach and its performance, a case study was also tested using IGIM system design.

Bibliometric analysis of Building Information Modeling, Geographic Information Systems and Web environment integration

Building Information Modelling (BIM) is gaining traction in the construction industry for its potential to enhance Facilities Management (FM) through advanced visualization, analysis, and control. However, in Malaysia, the integration of BIM within FM is still emerging, with significant untapped potential. This paper explores the adoption and impact of BIM in FM in Malaysia. A qualitative research approach through interviews were conducted with five (5) FM professionals, including facility managers, BIM coordinators, and consultants, selected through purposive sampling to ensure a broad understanding of BIM in FM. The results were then analysed using content analysis to assess the current practice of BIM implementations in FM, potential applications, and the level of interest in the utilization of BIM in FM. The findings highlight a budding interest in BIM among FM professionals in Malaysia. It revealed, an adoption pattern concentrated in high-value projects and characterized by challenges such as the absence of standardized BIM practices in FM, limited BIM knowledge among professionals, and concerns over implementation costs. Despite these hurdles, the consensus among participants points towards an optimistic future for BIM in FM, driven by the recognized need for enhanced operational efficiencies and the potential for BIM to significantly improve FM practices. This paper concludes by advocating for increased BIM education among FM professionals, the establishment of FM-specific BIM standards, and initiatives to showcase the long-term benefits of BIM, thereby fostering a more robust adoption of BIM in the Malaysian FM sector.
