This paper intends to focus on interoperability issues in IT‐based the lifecycle costing (LCC) applications and on improving LCC decision making based on cost performances of various options of constructing techniques and materials, excluding energy calculations.

This project mainly is an IT development project based on industry foundation classes (IFC) models. The LCC tool is fully compliant with the system architecture of the nD modelling tool, and is based on the integrated nD modelling interfaces, which are IFC compliant and integrated with an interactive virtual reality environment. The functions of the LCC tool also provide integrated costs, database management and automatic calculations of some complicated LCC algorithms.

The advantages identified are as follows: First, this IFC‐based LCC tool demonstrates the interoperable delivery of building design information across different CAD systems. Second, the development techniques adopted in this case are more practical and cost‐ effective due to the easily accessible auxiliary tools. This also promotes the flexibility of the IFC‐based development.

The lack of real historical data of LCC collected from previous projects is still a major barrier to applying this tool in practice. The future research and development of this LLC tool will look at the lifecycle costing of building service and energy consumption.

The paper introduces the development of IFC based applications in lifecycle costing.

This article presents a case study on the Heritage Building Information Modeling (H-BIM) application in a historic village in Bursa, Turkey. The study addresses how tailor-made and highly structured H-BIM approaches can effectively be implemented in preservation applications for historic vernacular buildings in the rural architecture context.

Using inexpensive digital photogrammetry techniques tightly combined with an object-oriented BIM ontology, parametric meta-modeling and object/system propagation methods, the study employed a holistic H-BIM approach for capturing the materiality, building object behaviors and indigenous construction principles of a characteristic vernacular house that were synthesized in a parametric H-BIM model. The followed stages, steps and connected methods were systematized and articulated in a prototypical H-BIM implementation framework.

The study findings suggested that the developed parametric H-BIM approach can return effective results with the combined use of low-cost and practical digital photogrammetry with BIM methods. The flexibility and adaptability of the parametric H-BIM implementation framework facilitated the synthesis of a comprehensive H-BIM model and allowed an in-depth evaluation of local architectural heritage with its physical, spatial and environmental characteristics. The proposed H-BIM approach also provided significant documentation and system-specific assessment benefits for preserving the vernacular examples which are prone to extinction especially due to structural and systemic deterioration.

The study proposes a feasible, practical and replicable H-BIM implementation methodology for vernacular preservation applications. The knowledge-embedded H-BIM approach, flows and techniques presented in this study provide a holistic and systematic H-BIM framework – with the integrated use of digital photogrammetry and parametric meta-modeling methods – that has the potential for the democratization of H-BIM applications in education and practice.

The transformation of cities from the industrial age (unsustainable) to the knowledge age (sustainable) is essentially a “whole life cycle” process consisting of planning, development, operation, reuse and renewal. During this transformation, a multi‐disciplinary knowledge base, created from studies and research about the built environment aspects is fundamental: historical, architectural, archeologically, environmental, social, economic, etc., and critical. Although there are a growing number of applications of 3D VR modelling applications, some built environment applications such as disaster management, environmental simulations, computer‐aided architectural design and planning require more sophisticated models beyond 3D graphical visualization such as multifunctional, interoperable, intelligent, and multi‐representational. Advanced digital mapping technologies such as 3D laser scanner technologies can be enablers for effective e‐planning, consultation and communication of users' views during the planning, design, construction and lifecycle process of the built environment. These technologies can be used to drive the productivity gains by promoting a free‐flow of information between departments, divisions, offices, and sites; and between themselves, their contractors and partners when the data captured via those technologies are processed and modelled into building information modelling (BIM). The use of these technologies is a key enabler to the creation of new approaches to the “Whole Life Cycle” process within the built and human environment for the twenty‐first century. This paper aims to look at this subject.

The paper describes the research towards BIM for existing structures via the point cloud data captured by the 3D laser scanner technology. A case study building is used to demonstrate how to produce 3D CAD models and BIM models of existing structures based on designated techniques.

The paper finds that BIM can be achieved for existing structures by modelling the data captured with 3D laser scanner from the existing world. This can be accomplished by adapting appropriate automated data processing and pattern recognition techniques through applied science research.

BMI will enable automated and fast data capture and modelling for not only in design and planning, building refurbishment, effective heritage documentation and VR modelling but also disaster management, environmental analysis, assessment and monitoring, GIS implementation, sophisticated simulation environments for different purposes such as climate change, regeneration simulation for complexity and uncertainty and so on. As a result, it will increase the capability for fast production of virtual reality models and comprehensive and sophisticated simulation platforms.

The paper provides useful information on BMI for existing structures.

This paper introduces a building information model (BIM)‐based user pre‐occupancy evaluation method (UPOEM), which is applied in architectural design stage to narrow the gap between inexperienced clients and designers. It aims to improve the communication efficiency.

The literature review studied the related technologies applied in the UPOEM, which includes building information modeling, user activity scheduling, and requirements documentation method. Based on the building information model, a virtual environment involving the end‐users' daily activities was built up. In this virtual environment, the clients can observe how their organization will be accommodated in the built environment according to their daily work routines. A requirements and feedback interface was designed to facilitate the clients to conduct a pre‐occupancy evaluation and store the relevant information into the database.

In briefing and design stages, there is a considerable gap between the inexperienced clients and designers when the clients specify requirements and review the design solutions. In the UPOEM, the user activity simulation model can facilitate clients to obtain a better understanding of the design. The requirements and feedback interface can also help them specify requirements and give comments to the design. Thus it provided an alternative tool to improve the efficiency of the designer‐client communication.

This research established a virtual platform which involves both building information and the user activity information. This platform can be further extended by the integration of more building performance simulation tools. Thus it provided a potential to bring the traditional post occupancy evaluation process to the pre‐construction stage.

The implementation of this method in practice can improve the efficiency of the designer‐client communication, and also maximize the clients' satisfaction during the requirements specification and design review process.

This study built up a collaborative working environment for both designer and clients. It can strengthen the designer‐client relationship during the briefing and design stage.

The user activity simulation and requirements management methods are innovatively applied together to enhance the clients' performance during designer‐client communication.

An accessible or inclusive building design does not disable any user; it should enable the independent and equal use of a facility by all. With the introduction of the Disability Discrimination Act 1995 (DDA), the consideration of issues such as access and inclusive design become even more important. Space analysis is an important aspect of the current accessibility assessment. Existing space analysis techniques, such as space syntax, have tackled the local and global accessibility of a building layout using graph theory. However, there are difficulties in the automatic transfer of design information from architectural drawings into a space analysis tool. With the recent development of the building information model and Industry Foundation Classes (IFCs), it is now possible to automate the transfer process. This paper demonstrates the automation process and how it can be used in accessibility analysis.

This paper aims to investigate how digital capabilities associated with building information modelling (BIM) can integrate a wide range of information to improve built asset management (BAM) decision-making during the in-use phase of hospital buildings.

A comprehensive document analysis and a participatory case study was undertaken with a regional NHS hospital to review the type of information that can be used to better inform BAM decision-making to develop a conceptual framework to improve information use during the health-care BAM process, test how the conceptual framework can be applied within a BAM division of a health-care organisation and develop a cloud-based BIM application.

BIM has the potential to facilitate better informed BAM decision-making by integrating a wide range of information related to the physical condition of built assets, resources available for BAM and the built asset’s contribution to health-care provision within an organisation. However, interdepartmental information sharing requires a significant level of time and cost investment and changes to information gathering and storing practices within the whole organisation.

This research demonstrated that the implementation of BIM during the in-use phase of hospital buildings is different to that in the design and construction phases. At the in-use phase, BIM needs to integrate and communicate information within and between the estates, facilities division and other departments of the organisation. This poses a significant change management task for the organisation’s information management systems. Thus, a strategically driven top-down organisational approach is needed to implement BIM for the in-use phase of hospital buildings.

The heating, ventilation and air conditioning systems are responsible for a significant proportion of the energy consumption of the built environment, on which the occupant's pursuit of thermal comfort has a substantial impact. Regarding this concern, current software can assess and visualize the conditions. However; integration of existing technologies and real-time information could enhance the potential of the solution proposals. Therefore, the purpose of this research is to explore new possibilities of how to upgrade building information modeling (BIM) technology to be interactive; by using existing BIM data during the occupation phase. Moreover, the research discusses the potential of enhancing energy efficiency and comfort maximization together by using the existing BIM database and real-time information concomitantly.

The platform is developed by designing and testing via prototyping method thanks to Internet of things technologies. The algorithm of the prototype uses real-time indoor thermal information and real-time weather information together with user's body temperature. Moreover, the platform processes the thermal values with specific material information from the existing BIM file. The final prototype is tested by a case study model.

The outcome of the study, “Symbiotic Data Platform” is an occupant-operated tool, that has a hardware, software and unique Revit-Dynamo definition that implies to all BIM files.

The paper explains the development of “Symbiotic Data Platform”, which presents an interactive phase for BIM, as creating a possibility to use the existing BIM database and real-time values during the occupation phase, which is operated by the occupants of the building; without requiring any prior knowledge upon any of the BIM software or IoT technology.

The purpose of this study is to outline the problems associated with asset information management using the Construction Operations Building Information Exchange (COBie) standard and to analyse the causes of industry failure to successfully adopt the standard. Based on this analysis, the paper will propose a process model, namely, Lifecycle Exchange of Asset Data (LEAD) to manage asset dataflow between all building stakeholders from design to construction and ultimately to the facility management team. This model aims to help the construction supply chain to produce complete and high-quality asset data that supports the operation phase of the built environment.

A review of relevant studies provided a theoretical background for this study. The authors then collected and analysed COBie data from five live construction projects using building information modelling (BIM) projects from different design and construction companies. The process model is based on an industry placement within Bouygues UK construction company, which was a Tier 1 building contractor in London in the period from December 2016 to December 2018. The researcher used an inductive approach observing current practises in two construction projects to produce “LEAD” model. Then a focus group was conducted with industry experts to discuss and refine the process model.

Analysis of literature and data collected in the course of this study revealed that although COBie is a BIM Level 2 standard in the UK, there is currently a low success rate in producing complete and accurate COBie data in the UK construction industry. This low rate is because of COBie’s rigid data syntax/structure, complexity and ambiguity of its data exchange process, which suggests that COBie may not be the future of the industry. Based on these findings, the study proposed a process model, namely, “LEAD,” to improve COBie output and also to be used with project-specific information requirements.

To the best of the authors’ knowledge, this paper is one of the first to focus solely on asset data exchange process using COBie standard and highlights the problems the industry faces in this remit. The study is based on industry placement for two years, so the analysis is based on actual and current industry problems. Current industry practices also informed the “LEAD” model, and the model provides a step-by-step guidance in producing and exchanging BIM asset data in all stages of the building lifecycle.

This paper provides a detailed analysis of the most common problems associated with COBie as an asset data exchange standard. Understanding these problems is of high value for industry practitioners to avoid them in projects. The paper also proposed a novel process model that can be used either to improve COBie quality or can be used with any project-specific data requirements.

The purpose of the presented research is to investigate which tasks among the ones performed during a buildings’ operational phase are perceived to be more inefficient and to investigate if the information within a building information model (BIM) can help improve task efficiency.

The Digital Built Britain (BIM Level 3) aims to extend BIM into operation by promoting a life cycle approach for buildings through an integrated digital environment. Nevertheless, the main focus of both BIM Level 2 and Level 3 is mainly on design, construction and hand over; therefore, the current understanding and use of BIM for a buildings’ occupancy phase is still limited. Current literature and research focusing on BIM and building management show only marginal use of the technology, especially in terms of how BIM can be used beside for maintenance.

The paper presents the results of an online questionnaire survey aimed to ascertain the level of perceived inefficiencies of operational tasks. Through the analysis of Industry Foundation Classes (IFC) data models, the research identifies the data set needed to improve the efficiency of the tasks and presents a structured implementation plan to identify the information that should be prioritized in the model implementation.

The study presents part of a methodology developed by the author aimed to implement a BIM model for existing buildings including information that would support the management of the single facility/portfolio. While other studies have considered BIM and the operational phase, especially in relation to asset maintenance, this study has focused on understanding how the information included in the model can improve task efficiency.

Traditionally, progress in detail engineering in construction projects is reported based on estimates and manual input from the disciplines in the engineering team. Reporting progress on activities in an engineering schedule manually, based on subjective evaluations, is time consuming and can reduce accuracy, especially in larger and multi-disciplinary projects. How can progress in detail engineering be reported using BIM and connected to activities in an engineering schedule? The purpose of this paper is to introduce a three-step process for reporting progress in detail engineering using building information modeling (BIM) to minimize manual reporting and increase quality and accuracy.

The findings of this paper are based on the studies of experiences from the execution of projects in the oil and gas industry. Data are collected from an engineering, procurement and construction (EPC) contractor and two engineering contractors using case study research.

In the first step, control objects in building information models are introduced. Statuses are added to control objects to fulfill defined quality levels related to milestones. In the second step, the control objects with statuses are used to report visual progress and aggregated in an overall progress report. In the third step, overall progress from building information models are connected to activities in an engineering schedule.

Existing research works related to monitoring and reporting progress using a BIM focus on construction and not on detail engineering. The research demonstrates that actual progress in detail engineering can be visualized and reported through the use of BIM and extracted to activities in an engineering schedule through a three-step process.
