Requirements for Ontology Development in the AECO Industry

Abstract: This paper presents and discusses the requirements needed for the development of ontologies in the Architecture, Engineering, Construction, and Operation (AECO) Industry. With the increase of information modeling for all aspects of a construction project with a variety of software tools and technologies, there has been a major need of communication and exchange of information. An approach to improve seamless information exchanges is the use of ontologies. One major benefit of using ontologies is that the information and knowledge defined in the ontologies can be shared across domains. However, to do so requires standardized rules and requirements in order to share and promote reuse at the domain level. Significantly, with the increased demand of ontologies in the AECO industry, there needs to be standardization and consensus in the development and use of the ontologies to ensure the seamless transfer of information as well as realizing the full benefits of ontologies.

Construction Delay and Disruption Claims Assisted Through BIM Technology

Abstract: Construction projects are frequently subjected to delay and disruption leading to dispute between project participants regarding the entitlement to compensation. Challenges associated with the analysis of delay and disruption and the subsequent preparation of the claim conducted by a forensic analysis expert include the difficult retrieval of scattered, unstructured information and lack of adequate documentation, leading to weak analysis and therefore insufficient proof of causation and entitlement.This paper illustrates the chronological information generation regarding delay and disruption in the construction phase proposing a framework based on Building Information Modelling and structured information integration, to facilitate easy filing and retrieval of relevant documentation for claim preparation.

A Conceptual Model for Investigating BIM Adoption by Organisations

Abstract: Studies investigating Building Information Modelling (BIM) adoption proliferated in recent years. Existing studies are characterised by both deficiencies in the adoption drivers and factors identified and an insufficient demarcation of key terms and concepts used. The suitability of using the results of these studies to investigate a conceptual model for BIM adoption is therefore impaired. This study presents (a) a holistic set of drivers and factors that influence BIM adoption by organisations, and (b) the theoretical fundamentals for the development of a conceptual model for BIM adoption by organisations. The set of drivers and factors for BIM adoption can be used by researchers and practitioners for different purposes (e.g., assessment, ranking, adoption strategies). The theoretical fundamentals of the proposed conceptual model combine the essential lenses from the pertinent theories (i.e., innovation diffusion theory, and institutional theory) and models (i.e., diffusion dynamic model: top-down diffusion dynamics including formal and informal mandates). The model can be used to empirically investigate the decisions to adopt BIM by organisations and understand the varying influence of different adoption drivers and factors.

BIM Innovation Capability Programme of Ireland

Abstract: The Irish Government has requested that Enterprise Ireland, an organisation responsible for the development and growth of Irish enterprises in world markets to actively promote the use of BIM in Ireland. This promotion has taken the form of an opportunity for Enterprise Ireland clients to apply for a grant under their BIM Enable and BIM Implementation schemes and also through their funding of the BIM Innovation Capability Programme (BICP) of Ireland. The BICP is a two-year project (2016-2018) which seeks to capture the capability of the Irish Construction Industry and the Higher Education Institutes to respond to the increased requirement for BIM in Ireland. One of the primary responsibilities of the BICP research team is to collate data to assist the Irish National BIM Council (NBC) in the formulation of a National BIM Roadmap. To achieve this a global and local BIM study was undertaken in 2016. This involved extensive desk-top based research exploring the value proposition behind what governments and professional bodies are doing to advance BIM in their respective countries. The research identified a number of common themes or pillars that Ireland will need to further address before a roadmap is formally disseminated. After exploration of these pillars, within an Irish context, it was found that despite a lack of standards and contractual frameworks, it has not prevented the industry from deploying BIM on Irish projects

Towards mobile lean communication for production management

Abstract: This paper reports on an ongoing case study of a mobile computing pilot project at Sweden’s largest con-struction company, Skanska AB. The company has recognized the potential of a mobile computing platform based on the tablet computer user device for construction site management teams. A global initiative within the company has started with the aim of improving information management and project communication at production site operations with the use of tablet computers. The paper portrays Skanska’s ambition towards the creation of usefulness and benefit of the tablet platform for the site based mobile workforce in the initial development and implementation process. The evolving mobile computing project has so far been directly influenced by the needs of intended end users and pro-gressed in a trial and error fashion. The paper also discusses the role of mobile computing and project communication in a wider industrialization perspective; integration of project organization and technology that enables an effective platform for collaboration to facilitate leaner communication in the construction process.

Cognition Enhancement Using Virtual Reality in Apartment Customization

Abstract: The design and construction of customer configured apartments is challenging when customers are unable to interpret construction drawings or lack the knowledge or competence to deliver the decisions and information that is required from them. Builders dedicate significant managerial and technological effort to manage the customization process with their customers, and this process is commonly recognized to be inefficient. Studies suggest that one root cause is the fact that most customers are not construction professionals, hence decision making is often a challenging and sometimes unpleasant task for them due to insufficient product cognition. In this study we developed a virtual reality tool for the facilitation of an immersive presentation of yet to be built apartments to customers, speculating that cognition may be enhanced and facilitate the customization decisions. An experiment was conducted to identify and measure cognition differences. Some areas of measured cognition shown noticeable improvement which imply for significant cognition enhancement. Exploitation of the findings by future adoption of the examined method is discussed and suggested to construction companies.

Developing a Campus Wide Building Information System Based on Open Standards

Abstract: University campuses can significantly benefit from IoT technologies, especially from operational efficiencies and user experience perspective. Traditionally, such systems have been limited to lab based environments, where involvement of end-users is limited and the results may not reflect reality. To build IoT systems for real-world that are reliable and relevant, it is important to build experiments in real-world conditions and involve end-users. From technological perspective, there is a need for convergence of diverse fields ranging from Building Information Systems and Building Services to Building Automation Systems, IoT devices and finally the campus services that include academic and research activities.This paper outlines the efforts to develop a campus wide web based system called Otaniemi3D that provides information about energy usage, occupancy and user comfort by integrating Building Information Models and IoT devices through open messaging standards (O-MI and O-DF) and IFC models. The paper describes the design criteria and the system architecture and the workflow to generate the information needed to develop such a system.

Development of a Collaborative Process Mapping Activity to Improve Students' BIM Process Mapping Understanding

Abstract: The use of BIM has become increasingly common, which has led to a growing demand for construction professionals with BIM knowledge and skills. BIM education is a solution to meet this growing need. Prior research suggests students associate BIM with a software solution rather than as a process illustrating a need to modify the current educational paradigms. This paper explores a pedagogical approach to developing BIM process planning skills among construction students. The research extends the findings of prior work that tasked students with developing process maps in a peer-reviewed context. This current iteration of the research explores the use of a collaborative, team-based, activity to generate Level 1 and Level 2 process maps, as defined by a previously published BIM Project Execution Planning Guide. The students were asked to create the process maps individually at first, and then again in groups of three. Pre- and post-questionnaires were given to analyse the studentsÕ perception of their knowledge. The primary objective of the research was to elicit a perception based response with respect to (i) studentsÕ ability to create a process map, (ii) enhancing the learning process, and (iii) students' perception about their own knowledge of the BIM execution process. In addition to perception based questions, the authors made observational analysis of completed process maps. The studentsÕ confidence in their ability in creating a process mapping dialogue box appears to have increased because of the activity. However, the studentsÕ perception about their ability to arrange the activities in sequence and parallel and the ability to create process map did not have any significant improvement. Based on the questionnaires and the suggestions given, it can be concluded that in both activities, the students had difficulties understanding the process mapping language. Future research may address the implementation of new pedagogical methods, incorporating the findings identified in this research thereby improving the measurable outcome of the students understanding of Process Mapping specific to BIM implementation.

Implementation of Hybrid Simulation Modelling Framework in Construction

Abstract: The goal of construction system modelling is to improve construction work performance by tracking the dynamic behaviour of construction systems. Discrete-Event Simulation (DES) has been suggested as a supporting tool for management decision-making in order to capture the dynamic complexity of construction projects. However, the limitations of DES in modelling influential factors such as the individual and emergent behaviour of system entities have led to the combined use of Agent-based Simulation (ABS) and DES. This paper provides an overview of DES and ABS applications in construction, and then discusses rationale for integrating DES and ABS from the conceptual stage onwards. Furthermore, a hybrid DES-ABS conceptual framework is introduced and the challenges of this type of hybrid simulation model are explained.

Refocusing project delivery systems on adding value

Abstract: The ability to manage a lean supply chain that contains no non-value adding elements is the ultimate challenge. The research behind the paper's findings is based on the production of functional process models adopting IDEFØ methodology to portray information flows, participants, organisations and IT use. Key participants in 11 projects contributed to the research and subsequently verified the models. Analysis was then performed on the models, including checks for consistency and process integrity. A generic model was developed from the best practice elements of all 11 projects, alongside changes in construction procurement and out of sector best practice industrial design and production. The result is a new project generic process model that could form a blueprint for subsequent construction projects. The research continues through modelling and costing different project scenarios so that non-value adding activities can be isolated and eliminated from the supply chain.
