Ontology-aided FMEA for construction products

Abstract: The goal of improving the quality and the maintenance of building products, and the will to integrate the sustainable development objectives led us to propose an original method based on the use and adaptation of the Failure Modes Effects and Criticality Analysis (FMEA). This method relies among others on ontology use. It facilitates the FMEA proceeding. This paper aims to introduce innovative software specifically developed to perform more easily FMEA on building components. This software takes advantages of a structured knowledge base and an inference rule engine that allow a complete and formal description of the product to be analysed and an exhaustive analysis of all failures (degradations) that may occur.

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.

A strategic and comprehensive vision for future R&D in construction ICT

Abstract: The tremendous development in the past ten last years of the Internet and ICT at large (whether it be in general technologies like semantic modeling, knowledge mining, RFID or mobile technologies, or domain-oriented ones like e-commerce, collaborative spaces, digital mock-ups, etc.) has opened a large spectrum of potential applica-tions of ICT in the Construction sector. The real adaptation and deployment of ICT in Construction has indeed just started, and there is a high need to organize and plan future R&D actions for Construction ICT, while at the same time to better evaluate the benefits and thereby convince Construction actors. This is the role of the Strat-CON and BICT projects, respectively, which are introduced in this article in terms of their aims and major results.

Collaborative practices for the adaptation of IT services to sustainable building design projects. Case study of design assessment-related practices

Abstract: Many professionals of the construction sector feel a need for improvement of the Information Technology (IT) that supports their work. Our main hypothesis is that this improvement is strictly dependent of a good knowledge of business activities. This study addresses this issue, introducing a method to adapt IT supported services to business practices. This method is based on a structured approach aiming at (1) identifying Collective Practices, (2) focusing on actors’ Individual Practices and Operations, (3) distinguishing different technology-related Usages and finally (4) selecting or designing adapted IT services relying on precedent analysis. An example based on sustainable project practices will illustrate the approach.

Overview of Concepts for Model Checking

Abstract: This paper gives an overview and a description of different concepts for model checking. Model checking is defined as execution of predefined rules on a building information model, e.g. an IFC-file. Rules can be based on laws, regulations, codes, standards, advisory material or self defined requirements for generally or project specific use. The different concepts will be presented with a description and examples of use related to stages in the life cycle of the design process (ISO 22263:2008). The paper will discus mixed use of these concepts in basis of IDDS, integrated design and delivery (IDDS, 2010). Generally should model checking be use to support areas where the designer is not an expert – or other (repetitive) tasks human performance is error prone. An model who have passed all checks can at it’s best said to be “not bad”, and never to be the best designed building. Reasoned feedback is an important part of model checking.The following concepts will (so far) be presented: A) Validating model checking. The checking is performed against a set or rules, that all must be passed, or not activated, to pass the validation. Examples are checking against codes or standards. Following sub-types: Geometry based, information based and mixed systems will be explained. B) Asking model checking. This is rules applied on defined situations who ask for a choice between different alternatives. Examples are choose of venetian blinds and ventilation related to area of window. C) Self checking and adaptive model checkingExample of this is the adaptation of the diameter of the column in response to number of floors. D) Reversed model checkingExamples are checking a model and give feedback on which codes / standards, or parts of this that is relevant. Support for manual checkingReference:IDDS, 2010.

Development of an Urban As-Built Model: The Case Study of Aberdeen

Abstract: This paper is focusing on the local strategic development plan for the city of Aberdeen, UK, and examines the initiation of applying a regeneration plan to the city centre. For that purpose, Aberdeen City Council commissioned Robert Gordon University to develop a 3D as-built model of the city centre. The researchers developed a novel process to tackle data acquisition for urban scale as-built visualisations that would afterwards promote stakeholders' collaboration. A workflow was developed and tested with the aim to provide not only geometric accurate data of the current state but also meta-data in relation to historic and future applications. Terrestrial LiDAR systems were employed and rapidly advancing hardware and software was tested, evaluated and utilised.This project aims to have an impact to the 3D data acquisition in relation to urban scale projects that apply Terrestrial Laser Scanning technologies. Furthermore, the suggested workflow can be generalised for the production of urban scale as-built models for the purposes of design and planning decision making and delivery of sustainable infrastructure, transportation systems and overall sustainable communities. The paper concludes with further suggestions for the generalisation of the process and its adaptation depending on the application, i.e. transportation, green spaces.

Distance learning in engineering and construction education: pros and cons

Abstract: Distance education has rapidly emerged as a new avenue for teaching and learning in the engineering and construction disciplines. Much has been written about the benefit and the downside of distance education. Many stakeholders in the construction and engineering fields remain sceptical about the validity of distance education. In spite of this scepticism the American Council of Education estimated that 85 percent of traditional colleges and universities offered, or soon would offer distance accessible classes. China alone produces more than 100,000 graduates, with more than half of China’s 92,000 engineering and technology graduates having attained their degrees through distance education. A universal model for distance education in engineering and construction would include answers to questions about the reliability and validity of the distance curriculum. The virtual engineering and construction classroom will become much more student centred. The traditional classroom will likely be replaced with a more intimate virtual environment. The student centred distance learning archetype will include dynamic demonstrations of theoretical engineering and construction models allowing students to manipulate, experiment, and translate theories into real-world applications. The distance education curriculum in engineering and construction will likely include the creative use of virtual technologies, theoretical adaptation, and the incorporation of comprehensive evaluation of student performance. Distance education in engineering and construction in the future must provide an element of comprehensive student evaluation to be universally valued and accepted.

SYDOX/MATCOMP/XI: an information system adapted to the needs of construction actors

Abstract: This paper presents the SYDOX/MATCOMP/Xi French project, whose goal is to provide the construction actors with an IT-based, on-line aid for component specification and selection at different levels of the construction life cycle. We will describe the main features of the information systems (IS), then specific aspects addressed by the project. SYDOX is aimed at defining and demonstrating a prototype to access information about MATerials and COMPonents used in construction, implemented on a WWW server and focused on a restricted sub-part of construction products. We will present the work done: methodology for data structuring, structure of the IS, database structuring, user interface, use of scenarios (enabling a selection and an adaptation of the information retrieved, on the basis of a set of criteria commonly used by professionals), hypertext links towards a taxonomic structuring of the information, application to window and floor, and some perspectives for the IS.

Information technology strategies and adaptation of knowledge - a conceptual analysis in the construction industry

Abstract: The goal of this study is to construct an understanding of preparations, made for strategic decisions of information technology. The focus is on adaptation of knowledge and the types of knowledge adapted. The study concentrates on the software and hardware used for producing drawings and specifications in the construction industry - the companies suffer an unpredictable market environment and a large amount of published data. The study is based on two case studies - made in two different companies – a multinational with operations in different countries, the other a medium size, mainly active on the regional market. Both of the companies are forced to make development decisions about information technology by estimating future benefits, costs, risks and intangible values. This should evolve from a thorough reflection based on selected information and an assessment of the situational data. According to their attitude towards CAD development these companies belong to different classes: pioneer and follower. The pioneer makes a broad scope selection of information and organises it for decision making. The follower estimates both the benefits of the software and the actions of the competitors. He calculates the revenues and costs carefully before the decision. There is a large amount of information offered by software developers, scientist and other experts. On the other hand the knowledge needed for strategic decisions has to be inside the company. According to the pragmatist philosophy, knowledge is gained through elaboration of experiences. In a fast developing field - such as software development and communication tools - the possibility of gaining experiences is good. The problem is - due to continuous progress - that new experiences are the only that can help you construct adequate knowledge. Sustainable decisions need to be based on long term experience, but in the case of information technology, the emphasis must
