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.

Keywords: Ontology, Information Exchange, Semantics, Logic, Taxonomy, AECO Industry

Utility assessment of electronic networking technologies in construction

Abstract: Despite an explosive growth in virtually all areas of industry and commerce, Electronic Networking Technology (ENT) has only begun to make inroads into the construction industry practice. Although information exchange protocols in construction firms and on construction project sites make it difficult to take advantage of most ready-made solutions applicable in other industries, there is a significant potential of large benefits from the correctly developed and applied ENT solutions for construction firms and construction project site offices. This paper describes the ongoing research effort to determine variables related to the application of ENT protocols for the main types of construction project delivery systems and to measure the utility of ENT configurations in facilitating communication between parties involved in a construction project with respect to specific project delivery systems.

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.

Data warehousing in the construction industry: organizing and processing data for decision-making

Abstract: Construction organizations are critically dependent on data. But data must be available in suitable forms for use. Timely access to useful and meaningful information can enable construction companies gain competitive edge, increase client satisfaction, expand market share and enhance profitability. Vast amounts of construction operational data are scattered across multiple, dispersed and fragmented departments, units or project sites. In this paper, we present data warehousing as an emerging database management technology that can provide the resource for decisionmaking. We point out the difference between an operational database - used for transaction processing; and a data warehouse - intended to be used for analytic processing in management decision-making in the context of construction organizations.

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.

The learning of CAD for construction: technical abilities or visual?

Abstract: The increasing demands of the construction industry for individuals with good IT skills add continuous pressures on higher education to improve their methods of teaching. CAD training, as an important part of IT training for construction students, is becoming an essential part of the curriculum in most built environment schools. However, general CAD training is mostly concerned with providing students with technical skills rather than the initial ability of spatial visualisation. Indeed, existing training methods of CAD applications, do not take into consideration students? learning styles, and the differences in their spatial visualisation abilities. Considering that CAD students need to perform various activities within CAD applications to develop an understanding of building concepts and components, their spatial visualisation abilities and their learning style, remain the main barriers. This paper identifies the learning strategies required to assist with the learning of 3D modelling and describes a new approach adopted to examine students' Special Visualisation Skills. The paper also describes innovative e-learning approaches developed to reinforce students' learning of 3D CAD, tracking their progress and highlighting qualitative measures of their effectiveness.

Examples of product model transformations in construction

Abstract: This paper discusses the results of a case study of product model transformations and geometric reasoning techniques for a challenging project. The complex geometry in the Experience Music Project offers unique challenges in construction processes. Manual transformation of the design-centric product model prepared by the architect into a production model for construction is time-consuming. We discuss ways to transform a design view of a product model into a construction view emphasizing the value of product models supporting multiple views. Geometric reasoning aids in the planning, scheduling, coordination of the project, and modeling of temporary structures. We are developing methods to support these product model transformations using the geometric model.

The development of an integrated life cycle costing model using object oriented and vr technologies

Abstract: There is an increasing realisation of the importance of operation and maintenance as opposed to capital costs throughout the life of an asset. In addition, new styles of contracts such as PFI (Private Finance Initiative) are becoming more popular. This will require that the building product is addressed within its holistic picture including the design, construction and maintenance. It is therefore vital to embed the life cycle costing element of a facility within its design and construction. Whole Life Costing is a technique used to facilitate effective choice between alternatives in the search of economic solutions. Information technology, particularly integrated databases and VR (Virtual Reality), can provide the mechanism to facilitate the integration of the whole life cost information. The research project described in this paper aims to add a life cycle costing element to the design phase of the OSCON integrated database developed at Salford University in the UK. The current integrated database within OSCON supports the functions of design, estimating and planning. The proposed system will allow the user within a VR environment to navigate inside the building retrieving information about building components that need replacement or repair. A colouring mechanism will be developed to show various elements in different colours according to cost criteria. This would allow the user to easily inspect the building and get rough ideas of repair and maintenance programmes, running costs and cash flows. The system will allow data to be updated continuously so that it will enable the comparison with initial plans and estimates and provides a fresh view of future action and feedback.

Information link model for construction using artificial intelligence

Abstract: This paper reports on a novel project model developed to help clients plan, monitor and control their construction projects. It describes a knowledge-based system designed for this purpose. The paper initially concentrates on the practical aspect of knowledge acquisition indicating problems that were faced and solutions employed. Following this, the structure of the knowledge-based system which was developed is outlined and its use described. Conclusions are drawn as to the applicability of the model and the final system. The work undertaken shows that it is feasible to benefit from the field of artificial intelligence to develop a project manager assistant computer program that utilises the benefit of information and its links.
