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.

Developing a Horizontal Integrated Life Cycle Costing Analysis Model through BIM

Abstract: Advancing interoperability between design team applications has been a major challenge for advocates of open standards. The buildingSmart alliance and Open Geospatial Consortium Inc in the U.S. have developed and implemented an Architecture, Engineering, Construction, Owner Operator, Phase 1 Testbed that streamlines communications between parties at the conceptual design phase to establish an early understanding of the tradeoffs between construction cost and energy efficiency. The results of this Testbed combined with an on-going collaborative R&D project ‘Inpro’ co-funded by the European Commission to identify business and legal issues of Building Information Modeling in construction were used as theoretical propositions underlying a 2010 Delphi survey. This paper presents the results of one questionnaire of that overall study. It is anticipated that these results will contribute to (i) identifying the most appropriate applications for advancing interoperability at the early design stage, (ii) detecting the most severe barriers of BIM implementation from a business and legal viewpoint, (iii) examining the need for standards to address information exchange between design team, (iv) exploring the use of the most common interfaces for exchanging information, and (v) investigating the industry’s perception on whether the development of a Cloud based BIM Life Cycle Costing would be of significant use to the Irish and UK construction industry. The rationale for this research is to refine the results of the initial questionnaire, AECOO-1, and Inpro R&D projects in order to determine if a prototype based on developing a cloud integrated LCC model through BIM could be generated in the UK and, Ireland and if so, what would be the legalities of implementing such a project.

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.

Extensible enterprise computing for construction as a necessary pre-cursor for collaborative engineering

Abstract: "Our focus is to consider the construction industry as essentially an information processing system. In its ideal form, practitioners (each with an individual internal representation of design intent) interact with other practitioners by first interacting with an information processing system that manages various shared external representation of design intent. The underlying assumption (from an information technologist's perspective) is that design data is held in a sufficiently complete representation, and that changes to this representation are transactions that move the representation from one consistent state to another. We might call this 'enterprise computing' for construction. This ideal of 'enterprise computing' for construction can be compared to the realities of current practice. - Due to its fragmentation, the construction industry generally perceives its use of information technology in terms of multiple discrete 'individual' systems (with the resulting proliferation of discrete documents) rather than as an enterprise systems. - The drawing tradition, which represents building in 2D, with different representations of the same design split across multiple independently editable documents inhibits consistent management of design and the use of analytical tools. While these may be familiar arguments, there are new object oriented and data management tools emerging from key software developer, such as Bentley Systems, that are designed to address the specific needs of a 'construction enterprise', namely geometric generality, multiple application semantics, multi-user access, and transaction management. These systems also address the scalability and reliability issues required for deployment in practice. Again, arguments for (and advantages of) systems of this type have been discussed in the research literature for more than two decades. The difference is that these systems are ready for deployment. But with this prospect for a broader application of 'Enterprise Computing' for Construction, there are associated other significant issues which may concern both the 'strategic' and the 'creative' practitioners, namely: - Semantic completeness: building a sufficiently complete multi-disciplinary representation of design intent - Data integrity: where any intelligent components are used, these should not become 'orphaned', for example, by object ""instance"" data being detached from the definitions of the corresponding class - Data longevity: the integrity of design and other data should be maintained for the life-time of the building, across new hardware platforms and operating systems. Upgrades to the application and any intelligent components should not disrupt or invalidate existing data - Parallelisation of design: individual designers or engineers should be able to work in parallel, and then be able to synchronize their changes to design data with co-workers - Expressibility: architectural design and construction engineering are open-ended domains. Additional intelligent components should be capable of being added on a ""per project"" basis. Within this context, this paper will explore the essential 'tension' that exists within the Architecture and Construction sectors. On the one hand, there is a perceived need by construction managers for computing tools based on clearly defined and agreed schema to control the construction process (thereby giving economic advantage, comparability, etc.). On the other hand, creative designers who are under other competitive pressures, are expecting a different set of computing tools to allow the exploration of new building configurations and construction geometry. While in the former case a standardisation of schema (as the foundation of a traditional ""Enterprise Computing"" system) would appear to be in order, in the later case the essential 'open-ended-ness' of the creative process demands ""extensibility"" as a pre-requisite of any computing system. These differing requirements (and indeed, attitudes) within the user community, presents software developers with interesting challenges. What technologies (for example, object and/or relational) and what 'domain abstractions' are appropriate foundations for solutions for these differing requirements. Or indeed, what technologies and 'domain abstractions' can be used as the basis for broader set of applications whose design is intended to unify across this apparent ""management-creative"" divide…hence the theme of this paper: ""'Extensible Enterprise Computing' for Construction"". Fundamentally, this is not exclusively an issue of technology. We need to address both the technical and cultural issues if we are to realise our collective ambition of providing effective tools with which to support collaboration between the diverse range of interests that occur within the Architecture and Construction sectors."

Construction planning process improvement using information technology

Abstract: "Construction is a multi-organisation and interactive process. Successful completion of a project therefore depends on the accuracy, effectiveness and timing of communication and exchange of information and data between the supply chain. Unfortunately, the inefficiency of the existing method of communication has become a barrier to several innovative construction processes developed for the industry over the past four decades. Thus, research efforts and direction have since changed. Several studies now focusing on integration of the construction process with communication and standardisation of data exchange, taking advantage of evolving computer technologies. The capability of these technologies, object-oriented technology and the Internet has made a significant impact on other economic sector such as finance, manufacturing, insurance, etc., with significant improvement in performance and productivity. Thus the technology is available but the challenge is utilising the technology to develop method of improving the construction process. To ensure efficient utilisation of IT as enabling tools, formalisation and understanding of the construction processes are required. This will enable the identification of the problems and opportunities of the strategy, and its implementation and performance in practice. The paper presents a detailed model of pre-construction and construction planning processes, based on an on-going research project, that form the basis of the developed planning system. The detailed process mapping methodology using CASE tools and the associated integration of IT tools, as an enabler to aid and improve the planning process, are described. The system provides an interface for integration of CAD data, using IFC objects, within the system. The application of the system offers a promise of significant improvement in both pre-construction and construction processes."

A tool for developing knowledge management strategies

Abstract: While organisations recognise that Knowledge Management (KM) is essential for improving performance, many have difficulties in developing strategies for implementation. The nature of knowledge is of particular complexity in organisations such as those within the construction industry characterised by temporary 'virtual' organisations formed for the completion of projects. A significant proportion of construction organisations realise the benefits of KM but most remain at the infancy stages of developing and implementing KM strategies. This paper identifies the need for a methodology to help organisations establishing these strategies. It then describes a framework developed within the CLEVER (Cross-sectoral Learning in the Virtual Enterprise) project at Loughborough University. The framework introduces a methodology that supports KM at both the tactical and strategic levels in order to aid organisations, especially in the construction and manufacturing industries, in developing KM strategies. The methodology was encapsulated into a prototype software system to achieve a simpler format and is easier to use. Industrial collaborators evaluated both the paper format and the prototype software and it is evident that the developed methodology has the potential to provide a very useful way for developing KM strategies and that very little exists elsewhere to assist companies in developing KM strategies in this way. The software prototype was seen as an important enhancement to the paper version. The inviting format, simplified guidance, reduced input duplication, and automated report generation were found the most significant enhancements. The focus of this paper is on the development and operation of the prototype. Its key benefits and lessons learned in implementing it are highlighted in the paper.

Keywords: Construction organisations, knowledge management, KM strategies, software prototype.

Improving construction communication: the impact of the on-line technology

Abstract: The Special Projects Administration (SPA) of the Ministry of Public Work in the State of Kuwait is responsible for managing the construction of Kuwait's prestigious facilities that are, usually, complex and costly. This paper suggests a Web-Based Information Delivery Intranet Site as a complementary communication tool that would enhance the delivery and exchange of information on the SPA's construction projects. Also, the paper includes areas of improvements to the SPA's communication process as a result of incorporating the WWW technology in communication. Improvement on the information delivery time is found to be the most significant.

Computer aided strategic planning

Abstract: Modelling concepts developed to analyse project strategic decisions have been extended and implemented in a computer system leading to a generalised methodology that allows modelling and evaluation of strategic decisions in almost any decision area. Some recent application areas of this modelling system are: strategic planning, evaluation of environmental policy impacts and evaluation of risks in owner contractor relationships . The system uses concepts of cross-impact analysis and probabilistic inference as the core of the analysis procedure. A modular model structure and a simplified knowledge acquisition procedure has been designed to avoid the excessive cognitive demands imposed to the users by the original cross-impact methodology. A simple questioning process is used to guide the discussion and elicit information in an ordered manner. The result is a powerful but easy to use computer modelling system where managers, or other potential users, are not exposed to the complexities of the mathematical model. The computer system is implemented in a Windows 95 platform and it provides a graphical interface to help the users in building a conceptual model for the decision problem. The model is a simplified structure of the variables and interactions that influence the decisions being analysed. Influences and interactions assessed by experts or decisions makers are stored in a knowledge base. The system provides powerful analysis capabilities, such as: sensitivity analysis, to identify the most important variables in the decision problem; scenario analysis, to test decision under different environmental conditions; prediction of selected performance outcomes; risk analysis, to identify the risk involved in different alternatives; comparative analysis of the effects of alternative actions on individual or combined performance measures; explanatory capabilities through the model causal structure; etc. The computer model can translate expertise collected from multiple experts into a prediction of significant outcomes for decision-making. The model allows management to test different combinations of options and predict expected performance impacts associated with the decisions under analysis. The use of this decision-support tool can provide valuable insights on alternative options for strategic decision-making

Information technology teaching at the University: an experience at the Faculty of Architecture in Naples

Abstract: The experiences illustrated here refer to didactic activity carried out at the Faculty of Architecture of the University of Naples; in particular these concentrate on the technological aspects of the teaching of architecture. We can consider the evolution of the architect from individual operator to manager of the multi-disciplinary aspects of the building process (building process manager) as a reality in today's Italy. The Support Systems of Information Technology (ITSS), can be of great importance €or this professional figure, and for this reason it is important to include him/her in the teaching process. I personally have involved fourth and fifth year and last-year undergraduate students in the following subjects at the experimental stage: degradation diagnosis supported by m Expert System in courses of the Technology of Building Rehabilitation; co-ordinated System of tests in degradation of existing buildings; the use of three-dimensional programmes to survey and visualize rhe territory; rapid analysis of degradation in the maintenance of urban facades. * In these and other similar works I'TSS has played a significant part for a global synthesis in students' methodological approaches, being an inttoduc tion to new Information Technology potentialities.

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.
