Shifting the construction interoperability paradigm, in the advent of Service Oriented and Model Driven Architectures

Abstract: A major difficulty construction companies are currently facing is the lack of interoperability of software applications to manage and progress in their business. Organizations are being pressured up by new business relationships, driven for instance by new contractual challenges, which the exchange of information and documents with new partners are often incapable of being executed automatically and in electronic format. This is principally due to problems of incompatibility with the information representation adopted by the software applications they are working with. This problem arises not only during the project phase but also across the whole life cycle that includes operation and maintenance stages. In order to create the enabling conditions for the deployment of the electronic collaborative and commerce platforms it is fundamental to understand the variables that may influence its development, and how they determine the configuration of the e-platform. This paper, after present technology driven standards for the construction industry data management, it proposes the adoption of the emerging Service Oriented and Model Driven Architectures to shift forward the interoperability paradigm in this industrial sector. The paper illustrates some scenarios where significant impact is expected when adopting the proposed methodology.

BUSINESS INTEROPERABILITY IN THE CONTEXT OF BIM-BASED PROJECTS

Abstract: This paper proposes a model that closely captures the factors that are responsible for Business Interoperability in the context of collaborative business processes for the deployment of Building Information Modeling. The Business Interoperability Quotient Measurement Model (BIQMM), uses an interdisciplinary approach to capture the key elements responsible for collaboration performance and BIM platform configuration. Through the quantification of the relevance of each element to the particular collaboration scenario, and with the combination of the BIQMM with a multi-criteria decision making tool, the Analytical Network Process (ANP) approach, this model enables a quantitative analysis of Business Interoperability for BIM-based projects, so that an overall interoperability score can be calculated for enhanced performance measurements. An application scenario is presented and the application of the BIQMM and ANP, provides a comprehensive framework for interoperability measurement. The paper concludes by recognizing that relationships between business interoperability and true AEC performance improvements and subsequent economic benefits derived from BIM-based approaches needs to be further developed.

An approach to modelling the dynamics of the design process in architecture

Abstract: This study presents a brainstorming on the dynamics of the design process in architecture. It is motivated by the needs and the evolution of the professional practice, and based on their study: it is exposed to allow us to learn the appropriate lessons for a future modeling of this dynamics. We will introduce our working hypothesis of the component dynamics and suggest a model for dynamics of design process in architecture.

Visualization of asphalt paving process during operations on site

Abstract: Presently important changes are occurring in the road construction industry, resulting in changing roles of road agencies and contractors. Additionally, a lot of new asphalt mixes with new properties are introduced, such as warm or even cold asphalt mixes, thin surfaces, etc. Despite these changes, the current asphalt paving process still heavily relies on the skills and experiences craftsmanship. Instruments to monitor key process parameters are seldom applicable. To overcome these limitations, real-time visualizations of key indicators such as asphalt temperature could provide decisive information to working teams oriented to adjust their operations on site. To move towards real-time decision making support, this paper introduces a workflow to deliver information in meaningful way by providing close to real-time and easily understandable visualizations of asphalt temperatures to roller operators. Using modern technologies like DGPS, temperature linescanner, and wireless connection on site it is possible to deliver visual information about asphalt temperature to support roller operators’ decision making regarding working paths. To implement user-oriented visualization we outlined an overall workflow including equipment selection, infrastructure organization, data processing and visualization phases. We validated the feasibility of workflow implementation through visualization of asphalt temperature on a real-world asphalt paving project.

Designing IT services for the Construction Industry. Lessons learnt for Selection of Validation Techniques

Abstract: Setting up collaborative working practices is a major stake in construction projects because each project is specific in terms of actors involved, documents produced and building elements designed. In such contexts the use of IT groupware tools to improve collaboration and their efficient appropriation by AEC practitioners is really a challenge. Designing such innovative collaboration-support services is an issue largely addressed in the scientific community especially to identify the factors of success/failure of the tools, but also to identify the scientific experimental approaches underlying it. This article describes five case studies of cooperation-support IT developments and for each of them the validation techniques used. It suggests an analytic framework distinguishing between 1) research project aims, 2) working practices and 3) IT developments types. Finally it introduces three experimental levels to be achieved in various research projects types and describes their related experimental properties.

The importance of engaging engineering and construction learners in virtual worlds and serious games

Abstract: The engineering and construction industries require their workforce to undertake complex learning and training activities. Exposing new employees, graduates, or apprentices to these environments could endanger their safety and the safety of those working with them. On site education and training also requires an investment of time from skilled individuals and companies. Problems accessing environments, such as construction sites, heavy plants or chemical manufacturers, are substantially heightened by the need to risk assess and comply with Health and Safety legislation making the traditional “hands on” and “shadowing” approaches to training and education more complicated than in the past. These difficulties are also compounded by changes to the geographical locations (e.g. distance learning, on site) of those studying to join these career paths or progress within them. Therefore, educational institutions and trainers must consider how to deliver this skill based learning for both those with access to academic premises and those learning at a distance. New technologies such as serious games are one of the solutions being explored. This paper undertakes an analysis of safety issues and safety training and learning methods relating to the construction industry. The paper takes its start point from a Health and Safety Executive commissioned report in 2003 (Hide et al, 2003) and questions if sufficient improvements in safety have been achieved within the construction industry since its publication. Then, the paper investigates the development of education and training that meets the necessary reality and complexity of engineering and construction sectors and the ability of serious games to provide timely and accessible training to achieve competency within these sectors.

Collaborative Environments and its Effects on Construction Companies: The Current Context

Abstract: The ability of Information and Communication Technology (ICT) to improve and enhance organisation’ productivity as well as their competitive situation has never been greater. Emerging technologies in the UK offer the construction industry many opportunities for computer supported collaborative environments, with regards to addressing some of the aspects that result in a complicated and complex construction process. However, the organisations adopting these technologies usually fail in achieving the full benefits from their implementations. Previous studies in the area have shown that 80 to 90 per cent of ICT investment did not meet their performance objectives. The fact of the matter is that collaborative environments have been evolving and effectively employed in large organisations and are believed to have high potential for Small and Medium Enterprises (SMEs), but the use of collaboration technology remains low among 99% of enterprises in the UK construction industry usually referred to as SMEs employing less than 250 employees. The growing popularity of collaborative environments in the construction industry has, unfortunately, not been matched by parallel empirical research for SMEs.The work reported in this paper serves two purposes. First, the results of an intensive literature review reveals general causes of failure in ICT implementations, and the key areas to focus on during ICT implementation for collaborative working. Second, results from exploratory case study that was conducted in order to assess the use of collaborative environments and their adaptation approaches are analysed in order to further explain what issues are preventing SMEs from achieving their utmost collaboration potential. Therefore, the paper blends a combination of factors which may affect the success of collaborative environments for SMEs and are believed to contribute towards the improvement and implementation of collaboration systems.

Productivity and cost analysis based on a 4d model

Abstract: Four-dimensional (4D) CAD models are being used more and more frequently tovisualize the transformation of space over time. To date, these models are mostlypurely visual models. Any evaluation of a 4D model, e.g., whether it presents aworkable construction sequence, is left to the viewer. The evolution of 4D CADdemonstrates the ability to provide a tighter link between visualization andanalysis tools. In this paper, we discuss how an intelligent 4D model helpsidentify time-space conflicts between concurrent activities and provide assistancein calculating more realistic cost estimates. The 4D system (4D Work Planner)presented here is based on symbolic and graphic product and process models, andprovides both the visual and analytical feedback necessary to reengineerconstruction sequences.

Information and communication in construction : closing the loop

Abstract: Both nationally and internationally, the architecture, engineering and construction (AEC) sector is highly fragmented : it is dominated by small and medium-sized enterprises (SMEs), the nature of information and knowledge can be dispersed among firms and organisations, and consortia are frequently formed from geographically dispersed firms. In recognition of the potential improvements to be gained through an integrated approach to project information used throughout the design, documentation, construction and operation processes, substantial research is underway in Australia to "close the loop" of information flows between designers and constructors. The paper will explore and discuss both the technology platform in terms of information and communications technology (mobile, high-speed and wide area networking linking the design and engineering offices with the construction site) and the information platform in terms of the content of communications between project stakeholders and the requisite information (traditional spatial as well as non-spatial data) of key concern to the stakeholders at various stages of the project lifecycle. The paradigm shift that has occurred over recent years from stand-alone personal computing (which reinforced fragmentation) to mobile and Wide Area networked computing now provides a platform capable of promoting integration, accessibility and co-operation within the sector with attendant gains in efficiency. A minimum requirement to achieve these gains is access to the right information (not just simple data) at the desired level of scale and detail for a particular stakeholder’s view - information which once collected can be stored and refined and then held for use elsewhere on the project without loss and without the need for subsequent re-entry. The information needs to be available quickly and easily, that is at the right time and in the right location for maximum benefit and project efficiency. Demonstration collaborative systems to support interactive Computer Aided Design and information exchange between project stakeholders such as architects, various engineers (electrical, hydaulic, mechanical, structural) and project managers, in an innovative collaborative manner have become available to bring dispersed project members together electronically. Such systems allow project members attached to a network to undertake a range of information access and exchange from simple e-mail; through on-site access to central project data sources via handheld computers; right through to the use of optional live (or pre-recorded) video to enhance collaboration. Using communications infrastructure, this functionality can be shared in various ways - in a corporate-wide environment between regional and/or interstate offices within a company, or in a consortium situation (between offices of a consortium working together on a specific construction project). The questions then arise as to how such systems fit into industry practice, and how the industry might adapt to embrace new opportunities provided by such technological advances. Ease of access to up-to-date, accurate project information for a range of project stakeholders is being extended through research in the US and Australia to close the loop between some of the stakeholders, and this will be discussed in detail in the paper. As well, the progress of industry-based support for a level of interoperability for building and construction information by organisations such as the International Alliance for Interoperability (IAI Australasian chapter) will also be discussed, plus the likely impact of the adoption of Industry Foundation Classes in the Australian building and construction industry in areas such as the design life for buildings based on durability of materials.

Information Technology and the Construction Industry: Another Tower of Babel ?

Abstract: The application of information technology (IT) to the construction industry has not been outstandingly successful and does not seem to have produced the benefits which other industries have achieved. A number of reasons for this are highlighted, some already well-known. However some serious mismatches between the technologies and the requirements of the industry are also identified. It is suggested that new developments in multimedia interfaces and computer supported co-operative working may reduce this mismatch and result in a higher level of take-up of the technology.
