Problem based learning in architectural education

Abstract: There is limited published research and discussion on pedagogical approaches in architectural education. Problem (or Project) Based Learning is used successfully in other professional disciplines, and, consequently, there have been attempts to utilise the same pedagogical approach in architectural education. This paper critically reviews PBL implementations at the Faculty of Architecture, Technical University of Delft (TUDelft), Netherlands and the De-partment of Architecture, University of Newcastle, New South Wales, Australia and draws general conclusions about the implementation of PBL in architecture and particular recommendations with respect to the teaching of architectural computing.

BIM Innovation Capability Programme of Ireland

Abstract: The Irish Government has requested that Enterprise Ireland, an organisation responsible for the development and growth of Irish enterprises in world markets to actively promote the use of BIM in Ireland. This promotion has taken the form of an opportunity for Enterprise Ireland clients to apply for a grant under their BIM Enable and BIM Implementation schemes and also through their funding of the BIM Innovation Capability Programme (BICP) of Ireland. The BICP is a two-year project (2016-2018) which seeks to capture the capability of the Irish Construction Industry and the Higher Education Institutes to respond to the increased requirement for BIM in Ireland. One of the primary responsibilities of the BICP research team is to collate data to assist the Irish National BIM Council (NBC) in the formulation of a National BIM Roadmap. To achieve this a global and local BIM study was undertaken in 2016. This involved extensive desk-top based research exploring the value proposition behind what governments and professional bodies are doing to advance BIM in their respective countries. The research identified a number of common themes or pillars that Ireland will need to further address before a roadmap is formally disseminated. After exploration of these pillars, within an Irish context, it was found that despite a lack of standards and contractual frameworks, it has not prevented the industry from deploying BIM on Irish projects

Building Support for Cloud Computing in the Irish Construction Industry

Abstract: The construction industry has been traditionally recognised as a fragmented sector associated with a poor level of implementation and penetration of Information Communication Technology (ICT) by Small to Medium Size Enterprises (SMEs). The ability to collaborate in parallel with a change management process system that requires a central repository that can act as a base for interoperability between various construction disciplines and their software applications has long been sought. The proposed collaborative solution is not an invention, but more of a practical innovation combining several earlier inventions into something new and compelling. Cloud computing is a collective term for a large number of developments and possibilities. It is a new layer of internet architecture that creates an open opportunity to add functionality to an increasingly global network. The characteristics of Cloud computing such as shared infrastructure, on-demand applications, elasticity and consumption-based pricing, allows all disciplines in the sector to benefit. As part of the Irish Construction IT Alliance (CITA) Enterprise Innovation Network (EIN) research on investigating eBusiness technologies for the Irish construction industry, this paper will present the findings of its research methodology in developing a Web based collaborative platform for the SME market. It is envisioned that this opportunity gap will enable SMEs to support data exchange, information sharing and supply chain collaboration across a secure and affordable network that will allow them to compete in a global environment.

The conception of making decision support system introduction into building structures design practice

Abstract: The paper discusses introduction of artificial intelligence into structural engineering practice. The necessity of this paper is accelerated by the information base (IB) and decision support systems exigency, as some standards are not completely designed and there is no statistical information on faults, defects and damage to various buildings. The article suggests creating a decision support system for the optimal structural design of buildings that takes into account a risk of a propagating rupture. The article describes possibilities of a decision support system, the stages of its development and structure. Conceptual solution of the proposed decision support system for the analysis of structures is illustrated by designing trade and business centre high-rise building. The system is based on a knowledge base, which is created during its development and can be updated and expanded with the advent of new codes of practice and new structural design recommendations. Expert system will be built on the basis of clear rules and recommendations from foreign and Russian codes of practice, as well as European standards, and international occurrences of buildings accidents. Optimization of structural elements is performed on the basis of a genetic algorithm. The effect of various genetic operators on the performance of the algorithm is investigated. A model of a genetic algorithm for optimization of steel structural elements is developed. The work is the attempt to create a complex approach to the structural design: the user can not only study the normative documentation, get advice, study the examples of calculation, but also take advantage of the proposed programs for the optimization of the design decisions. It is expected that expert’s knowledge on the analysis of buildings incorporated in expert system will improve the quality of the design, and as a consequence, the reliability of structures.

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.

Towards mobile lean communication for production management

Abstract: This paper reports on an ongoing case study of a mobile computing pilot project at Sweden’s largest con-struction company, Skanska AB. The company has recognized the potential of a mobile computing platform based on the tablet computer user device for construction site management teams. A global initiative within the company has started with the aim of improving information management and project communication at production site operations with the use of tablet computers. The paper portrays Skanska’s ambition towards the creation of usefulness and benefit of the tablet platform for the site based mobile workforce in the initial development and implementation process. The evolving mobile computing project has so far been directly influenced by the needs of intended end users and pro-gressed in a trial and error fashion. The paper also discusses the role of mobile computing and project communication in a wider industrialization perspective; integration of project organization and technology that enables an effective platform for collaboration to facilitate leaner communication in the construction process.

Automated construction schedule creation using project information model

Abstract: In this paper we will propose a method of using a project information model (PIM) for creating construction schedules. In the paper we will briefly review current available scheduling possibilities, which use combination of BIM and scheduling software. We realized that BIM lacks user specific data that is vital for proper schedule creation and has, on the other hand, too complex structure and software tools for planning personnel to understand. Through the use of simple 3D model viewer, user specific data and BIM, we are proposing a novel approach of schedule estimation in construction, which we call project information model (PIM). PIM is the process that is based on internal logics, that creates the estimated schedule and resource usage. After the PIM process, the automatically created schedule is included in BIM and made available to project managers and other construction stakeholders, to coordinate and carry out activities.

Modeling a project scope using a case-based reasoning approach

Abstract: The availability of a good, complete scope definition in the early stages of a project is widely recognized by industry practitioners as a key factor for overall project success. This paper presents a Project Scope Modeling Methodology for computerized decision support during the definition of a new project scope. The methodology is based on the effective reutilization of historical project scope definitions through the application of Case Based Reasoning (CBR), an Artificial Intelligence approach. In CBR, the previous experiences are reused in solving new situations re-ducing the complexities of modeling reasoning processes. By using CBR, the scope modeling methodology helps to find and reuse the most relevant historical information, allowing to easily consult and combine information from multiple scope definitions in a computerized environment. The resulting scope definitions are ready to serve as input information for different planning purposes. The application for conceptual cost estimating is discussed.

Process Model for Understanding Stakeholders Expectations in New Projects Development

Abstract: There is in construction a fundamental change in the making and delivering of successful new projects: the focus shifts towards value adding for projects based on a better understanding of stakeholders expectations. The process of modelling this new paradigm in construction will put “the creation of value in the eyes of the client”, central in the development of new projects. This paper describes a model that is designed to help stakeholders to achieve their expectations regarding urban and housing projects. The process of integrating different sub-models (costs and qualities) is examined and includes quality evaluations based on people’s preferences and willingness to pay. The model is developed through a methodological pluralism, identifying people-oriented variables. The different parts of the model are described, besides data requirements for each part. The development of the model was based on a case study carried out on the city of Guayaquil-Ecuador. Information obtained from a field work research was used for testing of the model. The study examines implications and limitations of the use of the model for inclusion of stakeholders. The paper concludes with findings regarding the identification of most preferred attributes by housing users and the use of alternatives methods to incorporated additional value to the projects, translated in more appealing profits for developers and the provision of better and affordable houses for the users.

A computer model for selecting equipment for earthmoving operations using queuing theory

Abstract: This paper presents a computer model “FLSELECTOR” for equipment fleet selection for earthmoving operations. The methodology based on the queuing theory is incorporated in a computer module to account for the uncertainties in that are normally associated with the equipment selection process. FLSELECTOR is capable of assisting the users in making decisions required for earthmoving operations, such as determining the size and number of trucks and excavators, haul road lengths and surface conditions, etc…These decisions are based on the calculated output for all feasible fleets. An actual case study is presented in order to illustrate the effectiveness and performance of the FLSELECTOR in comparison with the simulation method
