Logistics Management in Construction Industry

Abstract: The construction industry is often slower to adopt new technologies than other industries. Yet the construction industry shall embrace these technologies sufficiently in order to keep up with advances in other trades. One of the most crucial elements in construction management is productivity. And the adopting of new technologies such as mobile-based application can increase construction project productivity in such areas as materials management, tool use time, and labour motivations. Most of these aspects have been thoroughly investigated in academia; however, logistics management and its contribution to construction productivity have been insufficiently investigated, especially with respect to the use of advanced technologies. In this paper, we propose to develop a new platform to utilize modern technologies in the construction industry. Hence, the main objective of this paper is to introduce mobile-based application technologies into construction industry that will improve construction productivity by enhancing logistics management practices. The use of this model will not only help increase productivity in the construction industry but also it will make this industry more competitive with other industries. In order to achieve the main the goal of the paper, different building construction sites have been selected from which to collect data using direct observation, interviews and questionnaires. In order to ensure a high quality result, all participants were selected based on their relationship to the subject being examined. By using the outcomes of the data analysis to identify a potential solution, a computerized logistical management model was developed to examine how to enhance construction productivity and to improve logistics management practices. Many positive opinions have been granted form different constriction experts. Facilitating the communications between such project participants as contactors, subcontractors and suppliers is another expected result. Also, the model would help in organizing the schedule for the use of such heavy equipment as cranes.

Socio-technical management of collaborative mobile computing in construction

Abstract: The constant changes of plan and unanticipated events in the production process at construction sites result in communication patterns that are dynamic, spontaneous and informal. Most of the existing ICT tools do not sufficiently support informal communication for powerful collaborative problem-solving, management of site resources, handling of parallel process activities and do not correspond to the basic needs and work patterns at the construction sites. Mobile computing technologies have the potential to provide an inclusive wireless mobile ICT platform (voice and data) that can enable improved support for informal communication and on-demand data at construction sites, which can result in improved project collaboration leading to increased efficiency and productivity in the construction process. Still, an implementation strategy for collaborative mobile computing at construction sites is complex and must consider numerous issues regarding system capabilities, mobility, applications, services, integration of existing ICT systems, user interface and user devices to meet the requirements and behaviors of site workers in the mobile distributed heterogeneous construction environment. A mobile computing platform needs to be designed, implemented and managed with a socio-technical bottom-up approach realizing end user and group needs, understanding the separate issues of adoption on different organizational levels, and recognizing mobile computing as a process integrated enabling technology for improving collaboration and project communication throughout the whole construction process.

Human oriented mobile system for on-site problem solving

Abstract: Uncertainties and the dynamic nature of on-site activities require complex coordination of information, resources and tasks. Problems caused by unanticipated events must be solved concurrently and should avoid project delays and costs increasing. For effective solving of such problems, the immediate availability of information and a prompt response of project participants on various levels of project organization are crucial. A combination of both conditions facilitate the optimum decision-making in cases of unanticipated events. Based on experiences from a series of experimental projects called E-site, it is our strong belief that a large amount of potentials for on-site problem solving lies in the knowledge, experience and capability of the site staff themself. Therefore, there is also a need to effectively link together the rich knowledge and experience of site staff and include site staff into problem solving processes. This paper describes a human oriented on-site problem solving system supported with context-aware communication to help dealing with unanticipated events on construction sites.

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.

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.

ecoCampus: a new approach to sustainable design education

Abstract: Civil and architectural engineering education programs strive to prepare students to design built environments that will be used by society. Some of these built systems can be challenging for laypeople to visualize while learning the design process. This research focuses on improving the way that students visualize and engage with building design content through the creation of a novel educational tool for designing sustainable building elements. The tool prototype, called ecoCampus, is an educational game that uses augmented reality technology on a mobile computing platform. It allows users to visualize a possible building retrofit design in the context of an existing built space and also receive tailored feedback about their design. The prototype application was tested with 47 first-year architectural engineering students to better understand the benefit of this tool. The results of this implementation were analyzed and compared to the results of prior semesters’ students who were tasked with completing a similar retrofit design activity without the use of ecoCampus or a mobile computing device. This comparison suggests that students who completed the ecoCampus activity were more likely to complete multiple design iterations as well as experiment with materials other than those present in the existing wall, suggesting that ecoCampus may help to break the tendency toward design fixation. Additionally, students generally rated the experience as highly enjoyable, suggesting engagement with this teaching tool. Future work will implement the ecoCampus experience with students in several building-related majors to identify possible additional benefits that can be observed.
