Perceived customer value in construction information services

Abstract: The information needed to design, construct and manage a building is nowadays mainly produced, stored and made available in digital form. Information is produced partly in the design process itself. Design and procurement documents refer only to information produced elsewhere as external printed matter or databases (for example, describ-ing building products). An important channel for such external information is provided by specialized information service providers. In order to meet competition from companies’ homepages, search machines, internet start-up companies etc, established info-mediaries need to rethink their services as well as their business processes. A key issue is achieving a deep understand-ing of how customers perceive the value of these services and products compared to those of new competition enabled by the internet. A study of new business patterns and networks provides the empirical support for the concepts exam-ined in this paper. Traditionally, value is regarded as something inherent in the product; and which is handed over to the customer. More recently, research argues that value cannot be pre-produced. Value is co-produced by the customer, partly as a result of interactions between the customer and the supplier or the service provider. For services, value is, according to this view, produced and consumed simultaneously. Using this theoretical framework as a basis, the conclusions of the study are that it is not enough for construction infomediaries to produce just digitised versions of their traditional products, e.g. printed standards, and product sheets. They also need to gain a thorough understanding of their customers' busi-ness processes and, instead of producing products (or services), become facilitators of value creation for customers.

DEVELOPMENT OF COMPUTER ASSISTED LEARNING TOOL FOR EARTHQUAKE ENGINEERING

Abstract: Today, we live in the world where the information and communication technologies are developing faster than ever before. We receive information and learn from a variety of sources. However, such learning is rarely related to the official programmes of higher education. Lecturers must compete with, for example, Discovery channel, games and/or other audio/video/internet media. That is why many students today have great expectations which even the well prepared and quality books cannot satisfy. Besides, it is difficult to attract their attention when the lessons are not dynamic and the lectured subject is not illustrated as it could be, considering all the technologies available. This paper describes a possible approach for teaching the basics of earthquake engineering through the use of animations (simulations) and active participation of the students. It could be a great addition to classical teaching methods in civil and earthquake engineering. Besides, the idea and the development of the prototype of the learning tool are described. That type of media gives the lecturer the opportunity to animate students, to give them the possibility to dig deeper into the discussed subject, and to learn through experimenting (‘playing’) with carefully prepared examples.

A2D2A2D… Seamless transformations from analog to digital worlds in support of global teamwork

Abstract: In today’s communication intensive environment the rapidly changing nature of work, learning, and play is driven by more and more collaboration, globalization, digital media, interactive devices and spaces, mobility, and convergence of virtual and physical spaces and places. The people and their knowledge are the key corporate asset. Managing, transferring, and reusing knowledge can lead to greater competitive advantage, improved products, and more effective teamwork. The most effective means of knowledge creation and transfer from experts to novices in both education and industry settings is through stories and dialogue using analog channel such as verbal discourse, ges-tures, annotations, and sketching. Current knowledge capture and reuse solutions do not afford to capture and utilize the relevance embedded in these multimodal streams of communication. This paper explores innovative approaches to support (1) seamless transformations from analog and digital worlds, and (2) cross-media retrieval and interactive re-play of multimedia content in support of global teamwork.

Keywords: Analog, digital, knowledge management, dialogue, gesture, sketch, data mining, cross-media capture re-trieval and replay

Gathering End-user and Stakeholder Information in BIM-based Infrastructure Projects

Abstract: Improving customer orientation has been identified as one of the major challenges in the AEC industry. A number of reports have highlighted the need for a change, greater efficiency and stronger client focus on the construction industry. Customer orientation refers to the idea that a project is only successful if it meets the needs of its intended end-users. This could only happen if customer and end-user information is connected with the project for its whole lifecycle. In the house building, where the customer is usually known beforehand, service-related tools has been developed to capture end-users needs in the different phases of the project. However, Infrastructure projects differ from house building projects in the several ways, for example, end-users are presenting a big audience and the ownership of the projects are typically public authorities. These characteristics, together with the basic features of the project management, makes difficult to exploit past experiences to the future projects. One of the major strengths in the building information modeling (BIM) is that it enhances collaboration between the team members and allows the mutual channel for information exchange. However, there is lack of knowledge how end-user and stakeholder information and requirements can utilize and gather in the systematic manner from the design phase to the maintenance phase and for the infrastructure life cycle. In a present, it is widely noted that research system in this area has been found tangled and ineffective. In this sense, BIM could be also an effective tool for gathering, storing and utilizing end-user requirements, information, and knowledge.

Process modelling in the facilities sector: a case study

Abstract: "Facilities Management (FM) is a new field, which has strong correlation to the construction and property disciplines. Most of the investment in the construction sector is in the maintenance and management of existing facilities. Yet FM remains an under researched discipline, and is often excluded from the construction life cycle. The growing commercial market in FM, as well as new procurement routes such as PFIs (Private Finance Initiative) have placed FM and whole life cycle research firmly on the UK's agenda. To date the facilities sector has not benefited from process thinking. Process mapping and improvement initiatives are fairly new to the sector. SPICE FM is a current research project at Salford University, which aims to develop a process improvement framework for FM. The research starts by process modeling, in order to gain an initial understanding of the current situation. It then uses experience from other sectors, such as IT, to tailor an incremental framework for FM. The first SPICE FM case study is the FM processes of a large hospital, with 400 employees in the facilities department. SPICE FM is using object-oriented process mapping techniques, to gain an understanding of the processes. These results will be used to analyse the process characteristics and their major strengths and weaknesses. This paper introduces the SPICE FM research. It then describes the hospital case study providing examples of the process maps and interview results. Based on these results the process characteristics are highlighted and discussion is generated on how to channel the process improvement research in the facilities sector."

EFFECTIVE SEMANTIC WEB-BASED SOLUTIONS FOR CIVIL ENGINEERING

Abstract: The World Wide Web (the Web) has become widely recognized as the primary channel of communication and dissemination of information in industry. It has made immense amounts of information available and has been gradually accepted by users who now readily incorporate it into their daily lives. In civil engineering, despite the wide use of the Web, its use is still limited by the users’ willingness and ability to share their knowledge. The Semantic Web challenges this problem as it adds meaningful descriptions to information in a manner that facilitates automated analysis and extraction by computer systems. While many scholars in the field realize the importance of using such technologies to promote collaboration with various parties including the general public, research that is conducted on the Semantic Web and similar technologies is often disconnected from its application. Nevertheless, there is general consent that this collaboration is essential for the creation of sustainable solutions in civil engineering. This paper reviews and analyzes current research being conducted on this area in Europe and North America. We also propose methods that involve the Semantic Web to improve usability and effective information flow in city-scale projects.

Improving the brief through information and process modelling

Abstract: Due to the vast amount of information and knowledge involved in construction projects, clients often have difficulties in identifying and communicating their actual requirements. In order to address this information effectively during the briefing process, such information is modelled into structured data models using EXPRESS-G technique. The processes involved during the development of the brief, however, are modelled using IDEF0 technique.The developed models establish the foundation for the development of a computerised system, which utilise an object oriented environment. The implemented object oriented data models then form the framework for the presentation of the client's brief. These models, when implemented into the computerised environment, will significantly enhance the communication channel between the various parties involved from a very early stage of a construction project. The outcome is an improved brief, which fulfils the client's budgetary constraints.
