A prototype computer program for product design applied to the construction context

Abstract: In this paper we discuss the requirements for an information system for product design and present an information system in the form of a prototype computer program that tests these principles in the context of building design. Design is a product determination process, i.e. the properties of a possible product are determined during the process. Design can be categorised as routine or innovative. In routine design the product is well known and the determination process includes selecting a prototype solution and determining its variable attributes. Innovative design is necessary when no such prototype solution can be applied, and new kinds of things and new uses for known things have to be created. Innovative design is a search process characterised by adding and removing attributes from the product model. In an information system for routine design the product model can be an instance of a specific product type, whereas in innovative design the product model must be an instance of a much more generic thing. In the latter case, the classification of the product model is determined successively during the design process. Information systems can be characterised as open or closed concerning classification of model objects, and concerning definition of classes in the conceptual schema. An information system for routine design can be closed in both respects, while an information system for innovative design must be open in these respects, so that the designer can define new attributes and classes and reclassify model objects. Building design, especially during early stages, is an example of innovative design. In the paper we describe a prototype program for product design, with examples of its use in the construction context. The prototype supports the above-mentioned dual openness by implementing a data model where the product model may freely be given attributes and be classified on the basis of these attributes.

The status of construction EDI in North America

Abstract: Electronic data interchange (EDI) is an innovative technology that has been used effectively in the aerospace, automotive, and manufacturing industries for the direct computer-to-computer exchange of standard business documents. Documents that are routinely transmitted using EDI include purchase orders, purchase order acknowledgments, material releases, requests for quotations, supplier bids, and fund transfers. Over the past three years, the North American construction industry has embraced the usage of electronic data interchange (EDI) through pilot projects, full-scale implementations and the formation of a focussed EDI user group representing many companies--the Construction Industry Action Group ( CIAG). The basic concepts of electronic data interchange are presented and the status of the development of both national and international EDI standards is discussed. This paper will briefly outline the North American construction EDI evolution and discuss successful case studies, important findings and future directions of EDI in the industry.

3-D visualization and animation techniques in structural design education

Abstract: As technology rapidly changes, the importance of educating and training diverse populations of civil/construction engineering/science students becomes more critical. With the advances in information technology over the last decade, the traditional teaching format of having an individual lecture to an audience has been supplemented, and in some cases, replaced by the rapid development and implementation of new distance learning methods. Traditional lecture format teaching methods sometimes fall short of conveying the complex analysis and design principles that need to be mastered in structural design. However when the theories are exemplified in a virtual environment with multimedia, animation, interaction, and manipulated image visualization techniques, students' conceptual understanding are enhanced. The important advantages of the virtual reality environment over other computer-based design tools, are that it enables the user to interact with the simulation to conceptualize relations that are not apparent from a less dynamic representation, and to visualize models that are difficult to understand in other ways. The interactive nature of virtual environments made it a natural extension to the 3-D graphics that enable students to visualize real life structures before actually building them. The main objective of this research was to create an innovative structural design concept visualization methodology on a web-based interactive virtual environment. The approach adopted in this research was to create the interactive learning environment using Java and Virtual Reality Modeling Languages (VRML). VRML was the primary language used to create a virtual environment and 3-D simulation, and Java applets were created for interactive analysis, design and structural behavior animation over the World Wide Web (WWW). The presented paper illustrates the design concept visualization techniques for reinforced concrete structure analysis and design.

FIEMSER: Energy Efficiency in Smart Residential Buildings

Abstract: Buildings are responsible for up to 40% of energy use in most countries. However, there is a great potential to improve this figure, and ICT is one of the key tools to achieve it. This paper will present how the FIEMSER system will contribute to increase the energy efficiency in residential buildings through a double strategy: optimizing the operation of the building (energy demand, local generation and storage) and improving the behaviour of the building users. The FIEMSER system is an innovative Building Energy Management System (BEMS) for existing and new residential buildings that is been developed in the context of the Seventh Framework Programme (FP7). Current BEMSs have several weaknesses: predefined energy control strategies, lack of integration of the local energy generation with the building energy consumption, lighting system is completely decoupled from the HVAC system, based on wired control networks, limited interoperability, … FIEMSER system will define dynamic and holistic control strategies that take into account the current and future building operating conditions (building users activities, weather conditions, energy prices,…) and integrate the different energy related subsystems: HVAC, lighting, local generation and energy storage. The FIEMSER system leverages on the Service-Oriented Architecture (SOA) paradigm with the definition of modular service interfaces. This paradigm provides the necessary flexibility to adapt the system to the different configurations, integrate existing control protocols and emerging wireless ones, and support different GUI (Graphical User Interface). This paper will address the following questions: opportunities to reduce energy demand and increase local generation in residential buildings; operation scenarios; functional requirements of the FIEMSER system; the OSGI-SOA architecture that supports it and the associated data model.

Visualization of Failed Highway Assets Through Geo-Coded Pictures in Google Earth and Google Maps

Abstract: The Virginia Department of Transportation (VDOT) has adopted an innovative highway asset management program known as Performance-Based Road Maintenance. Under the Virginia Tech-VDOT Partnership for Highway Maintenance Monitoring Programs, Virginia Tech’s Center for Highway Asset Management Programs provides independent assessment and technical leadership to support innovations in highway maintenance contracting and asset management practices. In the past, VDOT’s only way of checking a failed asset item was to go out to the field. This was very time consuming, especially if the assets were numerous or far apart. Moreover, it was often difficult to locate a specific asset item failure in a given segment. In other cases, finding the failure was impossible, since the condition of some asset items can change in a short span of time. This paper presents the development of a comprehensive system to display pictures of failed asset items. The major contribution of this system is to provide VDOT a tool to check any failed asset item from any computer with an Internet connection, eliminating the need to go out to the field and visit each individual site. The proposed technologies and processes were implemented as a pilot project in the Staunton South 2009 Maintenance Rating Program Evaluation. Results from the pilot project were used to evaluate how the system can enhance current highway asset management practices.

Mobile augmented reality, an advanced tool for the construction sector

Abstract: Augmented reality is nowadays a novel technology that is acquiring great relevancy as a research area. This technology complements the perception and interaction with the real world and allows placing the user in a real environment augmented with additional information generated by computer. Throughout last years it is increasing the interest and the results reached in the technologies of augmented reality on desktop environments. However there are numerous environments of application of these technologies that require mobility of the user, need of access to the in-formation at any time and any place, in these cases there becomes necessary the utilization of mobile devices. Construc-tion Sector is a clear example. The development of mobile computing solutions is crucial in construction sites. The per-manent change of the site (workers, activities, work place, etc.) implies that users need to get permanently updated in-formation. Mobile computing solutions make this information available without reducing or disturbing the mobility and agility of the users. In this paper we present the mobile augmented reality as an advanced and innovative tool for the construction sector. This technology has a high potential to achieve more sustainability, profitability and higher quality level in this sector. It is structured in two main sections. An initial one that analyses the current status of the augmented reality technologies using mobile devices and describes the benefits provided by these technologies, the most recent challenges achieved, the novel applications and the problems not yet solved. And a second one that analyses the poten-tial applications of the mobile augmented reality in the construction sector and describes a scenario in which the use of mobile computing solutions makes possible to increase efficiency and safety in construction sites.

Digital Tools for the Construction Site. A Case Study: ACCEPT Project

Abstract: Construction projects often encounter problems related to scheduling reliability and to a mismatch between the expected and actual building performance. In order to reduce these problems, the ACCEPT project is developing an ICT system to manage construction works more efficiently by applying Lean Construction principles, to increase the quality of executed works by implementing interactive checklists and sensors, and to share information in real-time among different stakeholders. In the ACCEPT system, existing technologies such as Augmented Reality, BIM, mobile/wearable devices and sensors have been combined together to create an innovative ICT solution for construction management. The ACCEPT system consists of three interconnected applications: SiMaApp for mobile devices CoOpApp for smart glasses and Dashboard for PC. The main goal of this research paper is to describe the framework of the ACCEPT system and its applications.

Automated sustainability compliance checking process: proof of concept

Abstract: Building Information Modelling solutions are evolving to achieve effective integration in the construction industry. The emerging approaches of knowledge sharing and data processing push the researchers to re-engineer innovative automated processes for integrated 3D design that complies with regulations and statutory requirements. This paper presents a generic approach for automating BIM compliance checking with standards and best practice with a focus on sustainability related standards. A methodology will be presented to provide a reusable solution for compliance checking within a similar context. The proposed approach is generic in nature thus allowing implementation in different fields of engineering including electrical engineering, energy, water and electronic engineering. It is anticipated that the findings of this research will promote a fundamentally innovative BIM-based compliance checking for a variety of industry standards. In this approach, the RASE methodology is utilised to extract requirements from sustainability based regulations, with the goal of converting them into compiled coded rules for execution by a rule engine

It and E-architecture – a technological breakthrough, a techno knowledge race or a new paradigm in business?

Abstract: The impact of Information Technology on the growth of the knowledge society is profound. In an era when human intellectual creativity is highly valued, IT is a powerful tool enabling the analysis and development of ideas and concepts. Regarding IT as a means to automate business tasks aiming at some labour savings would be an extremely simplistic approach to a more complex concept. Designing systems that augment user capabilities, encourage further exploration and foster creativity will enable users to do what they have not been able to do before. Business environments where collaborative work relationships flourish become highly successful in the intensely competitive global marketplace. The synergy between IT and teams working together to accomplish mutual goals becomes the key to organisational performance. The AEC (Architecture, Engineering and Construction) industry in particular is undergoing dramatic changes due to the pervasive use of networked computers and multimedia equipment. The advent of the first PCs in the architectural profession in the early 1980s gradually started adding a new element of complexity to the architect’s job. The essence of the architectural work is the teamwork environment and IT is able to facilitate the design process and make project collaborations effective. Our research focuses on IT and its impact on architectural team environments. Recent emerging trends that will be analysed include architecture firms’ collaborations on national and international projects (firms experts in particular building types associate with local or regional firms called “architect of record” commissioned for the contract documentation and the contract administration stages of the project). The Royal Sun Alliance Building, Metropolis Apartments, Botany Downs Shopping Centre, DFS Galleria (all in Auckland) are some NZ examples of international collaborations with the design coming from the USA and Australia and Auckland firms commissioned as “architect of record”. Such trends necessitate the use of new technologies like advanced digital communications and hence the unprecedented boom of project extranets, or project WEB sites, and the emergence of the WEB-based architecture. Highly sophisticated architectural environments are built around Intranets, Extranets, the Internet and Video Conferencing systems. This enables the integration of architectural design, business management and team collaborations through computer technology. As a consequence, traditional roles and responsibilities in an office environment will change dramatically with fewer lower level routine tasks being available. Continually updating skills through on-going education becomes a lifetime commitment for the highly qualified industry professionals and for the company as a whole. A large number of computer software applications become indispensable for the highly efficient everyday functioning of an office. Some of the most significant buildings of the 1990s like F. Gehry’s Guggenheim Museum in Bilbao, Spain and S. Calatrava’s Extension for the Milwaukees’s Art Museum, Wisconsin, USA couldn’t have been made without CAD. Another interesting trend is the use of IT to define a building through its entire life cycle in a more comprehensive way. This covers not only the traditional design and construction phases of a project but also automated facilities management and even the building’s eventual demolition. Our research methodology encompasses an array of primary and secondary sources of information – literature review, international case studies and projects both pre and post IT revolution, interviews with experienced industry professionals, hands-on experience demonstrating WEB based concepts in practice and individual professional expertise. Research Outcomes and Conclusions: · Although technology has given us numerous new tools to be more productive and innovative creatively, the amount of quality architecture being designed may not necessarily increase. · It is academia that drives innovative uses of technology not industry. Academia has more time and resources to experiment and is not at the mercy of the vendors’ vision or how technology can or should be used. · Computing is in a never-ending flux. This change, for better or worse dynamically drives the way we do business. The entire industry must seek out these changes, create them, challenge them, foster, adopt or discard them to suit. · As object oriented CAD becomes more pervasive, more value will be added to the construction documentation. This value-add needs to be recognised and exploited. · As technology pervades, the design process, regardless, remains relatively the same. · Hierarchical business models and decision-making processes are no longer the norm. This fosters an atmosphere of collaboration and employee empowerment. · Talent is talent. Technology is no substitute for it.

Towards ICT-enhanced management support systems for optimizing infrastructure procurement

Abstract: Infrastructure procurement programmes of many public clients and large private developers, increasingly involve complex networks of stakeholders. Well balanced and 'fully informed? decisions are critical in optimizing resources to achieve agreed objectives. A research project in Hong Kong is aimed at developing an ICT (Information and Communications Technology) - enhanced MSS (Management Support System). This will empower the formulation of more effective and efficient construction project procurement and delivery/ operational systems - for innovative and improved 'total? management of construction projects - from a large client's viewpoint. Web-based Decision Support Systems (wDSSs) are being developed to help achieve such objectives, by capturing, codifying and mobilising both expert and experiential construction industry knowledge. Furthermore, web interfaces are being designed to mobilise the collective expertise of the entire project supply chain in real-time collaborative formats. These decision aids will enable the often fragmented multi-disciplinary project teams to build on 'state of the science? knowledge, past 'lessons learnt? and present best practices, in making more informed managerial decisions that will help to optimise inputs and reduce wasted resources. Potential benefits of wDSSs are demonstrated in this paper, through examples from the integrated framework and prototype modules/ models that are under development and 'construction' in Hong Kong. These cover a crosssection of infrastructure programme management decision scenarios, i.e. in: (1) multi-purpose contractor registration-prequalification, (2) dynamic performance appraisal of contractors and (3) evaluating 'extension of time? entitlements. Interim outcomes included herein are the basic MSS framework, pilot models of items (1) and (2) above and prototype modules of item (3) above.
