Possibilities and challenges created by a smart material in building performance simulation

Abstract: Smart materials are predicted to ‘revolutionise’ the A/E/C industry. They are supposed to enable a building to change colour, shape, size and opacity. However, past research shows that smart materials are still not used very often in engineering applications to their full potential. In this publication we advocate that materials should not be only chosen for simple properties such as visual, physical and insulating characteristics, but for capabilities such as being able to save/generate energy, store information, and to react to stimuli from their local environment. Therefore, this paper will research into the addition of SolaVeil to a window, its physical configuration and the possibility to model and analyse it through Building Performance simulation (BPS). This material is primarily designed to eliminate glare and redirect light. As a result it can reduce energy use caused by air conditioning and artificial lighting systems. This paper researches into the behaviour of SolaVeil in a computer simulation using two different case studies. The first will compare how changing the width but maintaining the reflective area affects illuminance distribution, and the second will determine which physical properties of SolaVeil are most effective. Finally, conclusions are drawn based on the case studies and it is shown that smaller width light shelves are the most suitable for an anti glare product. It is also determined that for SolaVeil to minimise glare in a room without compromising illuminance levels, it should have a light shelf angle of 40 degrees, cover between 40-60% of a window and its strips should be spaced 5mm.

Keywords: SolaVeil, smart materials, building system design, illumination.

The importance of engaging engineering and construction learners in virtual worlds and serious games

Abstract: The engineering and construction industries require their workforce to undertake complex learning and training activities. Exposing new employees, graduates, or apprentices to these environments could endanger their safety and the safety of those working with them. On site education and training also requires an investment of time from skilled individuals and companies. Problems accessing environments, such as construction sites, heavy plants or chemical manufacturers, are substantially heightened by the need to risk assess and comply with Health and Safety legislation making the traditional “hands on” and “shadowing” approaches to training and education more complicated than in the past. These difficulties are also compounded by changes to the geographical locations (e.g. distance learning, on site) of those studying to join these career paths or progress within them. Therefore, educational institutions and trainers must consider how to deliver this skill based learning for both those with access to academic premises and those learning at a distance. New technologies such as serious games are one of the solutions being explored. This paper undertakes an analysis of safety issues and safety training and learning methods relating to the construction industry. The paper takes its start point from a Health and Safety Executive commissioned report in 2003 (Hide et al, 2003) and questions if sufficient improvements in safety have been achieved within the construction industry since its publication. Then, the paper investigates the development of education and training that meets the necessary reality and complexity of engineering and construction sectors and the ability of serious games to provide timely and accessible training to achieve competency within these 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 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.

Transfer of road product model usage from academia to practice

Abstract: In Civil Engineering Informatics Centre at the Faculty of Civil Engineering, we are engaged in product models of construction objects. In product models, we see the key for integration of life cycle activities in the construction of individual objects. These activities are being weakly connected. Working on it, we have been focusing specially in the road design field. In the past few years we have developed a road model, called MCT, which is based on geometric road design. As a part of this project we have also made an application prototype, that uses advantages of MCT and enables simple road data transfer among particular life cycle phases. Yet in the early stage of our research project we were aware that our findings have to be tested in practise as soon as possible. Project was funded in part by the government institution that controls road building in Slovenia. For this reason we expected the investor to animate contractors to exchange data with our model. Unfortunately our expectations were not completely fulfilled and therefore the model wasn't verified in practise. Since we believe our model can rationalise road building procedure, we decided to carry out some extra activities, which would stimulate model usage. Therefore we established direct contact with some contractors involved in specific road life cycle phases. This wasn't an easy job, because a great number of small organisations are involved. Contractor's work is usually very clearly defined and computer is just a tool that helps him to do it quicker and better. For this purpose some extra functional modules of Road life-cycle environment (RO) were made and the existing ones were conformed according to the contractors needs. Since contractors are already using particular software to support their engineering process, we also persuaded software producers to include MCT in their programs for road design. This way, we gained broad software support for our model. Article fully describes a road model MCT, Road life-cycle environment RO and especially our efforts to introduce MCT into engineering practise.

A review on past, present and future of web based project management & collaboration tools and their adoption by the US AEC industry

Abstract: The term "Construction Project Extranet" (CPE) in this paper refers to Internet sites, which offer communication platforms, project management functionalities and hosted collaboration spaces for Architecture, Engineering and Construction (AEC) Industry projects. The paper focuses on web-based CPE offerings and examines in-depth analysis of the past, present and future of CPE solutions for design and construction projects as implemented by the AEC industry in United States. The paper builds upon previous research as well as structured interviews that were conducted with technology providers, users, and experts. The findings from the interviews and literature search were analyzed to address these questions: How has CPE technology been developed? How much are these systems accepted and used? What are the barriers to widespread adoption? How will the market for such systems evolve? The main goals of this paper are to fulfill the need of research related to the developments in this field, to provide a concise, updated overview of existing implementation practices and the current situation of CPE market, to discuss the reasons for slow adoption of CPE technology by the industry, and to understand the adoption and technology development patterns to forecast the future trends in this field.

The impact of electronic document management on construction information management

Abstract: This paper deals with the introduction of electronic document management (EDM) technology in the construction industry, and our current research knowledge about this topic. EDM has the potential to enhance the information management in construction projects considerably, without radical changes to current practice. Over the past fifteen years this topic has been overshadowed by building product modelling in the construction IT research world, but at present EDM is quickly being introduced in practice, in particular in bigger projects. Often this is done in the form of third party ASP services available over the World Wide Web. In the paper a typology of research questions and methods is presented, which can be used to position the individual research efforts which are surveyed in the paper. Questions dealt with include: What features should EMD systems have? How much are they used? Are there benefits from use and how should these be measured? What are the barriers to wide-spread adoption? Which technical questions need to be solved? Is there scope for standardisation? How will the market for such systems evolve?
