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.

Keywords: logistics management, advanced mobile-based application technologies, construction materials and equipment.

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.

ForBAU – The virtual construction site project

Abstract: The paper introduces the Bavarian research cluster ForBAU which has been launched in January 2008 with the aim of an improved planning and management of construction sites, especially in infrastructure projects. To realize this goal, the research cluster focuses on developing a virtual representation of the construction site which involves all essential aspects, including models of the buildings under construction, the environmental boundary conditions, the construction procedure, the logistics processes, and the required resources. The resulting virtual construction site forms one the one hand the basis for simulating the construction process, which allows to identify critical aspects of the construction project in advance and to adapt the resources and the scheduling accordingly. On the other hand, the holistic virtual representation of the real construction site is used during the execution phase to capture all available information about the project – enabling site managers, controllers and engineers to get a detailed overview on its progress and identify potential problems in an early stage.

Utility assessment of electronic networking technologies in construction

Abstract: Despite an explosive growth in virtually all areas of industry and commerce, Electronic Networking Technology (ENT) has only begun to make inroads into the construction industry practice. Although information exchange protocols in construction firms and on construction project sites make it difficult to take advantage of most ready-made solutions applicable in other industries, there is a significant potential of large benefits from the correctly developed and applied ENT solutions for construction firms and construction project site offices. This paper describes the ongoing research effort to determine variables related to the application of ENT protocols for the main types of construction project delivery systems and to measure the utility of ENT configurations in facilitating communication between parties involved in a construction project with respect to specific project delivery systems.

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.

Data warehousing in the construction industry: organizing and processing data for decision-making

Abstract: Construction organizations are critically dependent on data. But data must be available in suitable forms for use. Timely access to useful and meaningful information can enable construction companies gain competitive edge, increase client satisfaction, expand market share and enhance profitability. Vast amounts of construction operational data are scattered across multiple, dispersed and fragmented departments, units or project sites. In this paper, we present data warehousing as an emerging database management technology that can provide the resource for decisionmaking. We point out the difference between an operational database - used for transaction processing; and a data warehouse - intended to be used for analytic processing in management decision-making in the context of construction organizations.

Electronic news service for the european construction industry

Abstract: "Abstract The Electronic News Service (ENS at http://www.connet.org/NS/Intl/) is an AltaVista-like service which is specialised for the construction industry. It has been developed as one of the services in the EC project CONNET (Construction Information Service Network, at http://www.connet.org/). The ENS provides a searchable index of the contents of Internet sites relevant to the built environment. The database containing the source set of Internet sites to index has information on over 14,300 Internet sites across the world, categorised and classified by several criteria. This base set of Internet sites is drawn from all major lists offered to the construction industry (e.g., Yahoo, EEVL, UK-BRP, etc) and from published sources (e.g., Architect's Journal, Building magazine, etc). Over 35 major lists of site sources are utilised to build, maintain, and grow this set of 14,300 resources for the construction industry. The ENS service provides all in the industry with a free method of identifying sources of information based on the content of a web page or service based classifications. Users are able to define profiles for news they have an interest in and to be periodically, and automatically, notified of new or modified web pages and sites which meet their criterion. Running the ENS within the CONNET network provides mechanisms to link together all news services, which are available, to provide answers to user requests across complimentary systems, or even to take requests established for news and use them to identify other information sources of relevance (e.g., publications, software, products). This paper will describe the ENS, the methods it uses to gather and index construction information across the world, and the services it offers to the construction industry. However, the main content of this paper will be an analysis of the references gathered from the 35 major lists of resources which are established across the world. This analysis looks at the overlap that exists between the Internet sites referred to by each of these lists (which is remarkably small), the particular biases which appear in the lists (mainly towards English language and USA-based information), the currency of the sites in the lists (quite poor), and the predicted coverage of total construction-based Internet resources found in all of these lists. Our analysis of the lists also shows a relatively small number of 'must have' sites, which are included in the majority of the lists operated around the world. These 'must have' sites are highlighted and analysed to provide an understanding of what makes these sites of such great importance to the whole industry."

CONNET: a gateway to Europe's construction information

Abstract: "The EC funded project CONNET (Construction Information Service Network, at http://www.connet.org/) has developed a set of Internet-based information services for Europe. These services are linked through a European gateway for the construction industry which provides a ""virtual technology park"", accessible to the whole industry regardless of national boundaries. The gateway provides mechanisms to link all information services for the construction industry, and to establish national gateways to services which can then inter-operate across Europe. The CONNET consortium is moving to establish the existing services in all European nations, and to encourage further existing or planned information services to be linked. A suite of five Internet based services has initially been developed, comprising: a technical information centre; a waste exchange centre; manufactured product services; a calculation and software centre; and an electronic news service as described below: 1. The Technical Information Centre provides a single point of entry to locate technical information from quality providers, initially in the UK. The centre draws upon information held by the major publishers in the UK, with over 200 identified to link into the service. Once a publication is identified a user is able to place an order to purchase, or browse, the item. An automated notification service for users, based on their areas of interest, is also available as part of this centre. 2. The Waste Exchange Centre extends the current UK based system to better enable the disposal and reuse of site waste across organisations Nationally and in Europe. Availability of, and requests for, waste materials are automatically matched in order to broker greater reuse of materials. 3. The Manufactured Product Service enables Finnish and export-market users to identify manufactured products which match their design specification by incorporating product attributes into the selection system. Users are able to identify certified products and drag-and-drop CAD information into their designs. 4. The Calculation and Software Centre provides the European entry point for information on all software products available for the civil engineering domain (over 3,900 collated to date). Online demonstrations, online purchase, and even pay-per-use software is available. 5. The Electronic News Service enables members of the construction industry to register an interest in specific topics and to be notified of any Internet published news that matches their interest. The news sources are drawn from the main information providers and professional institutes in the industry, both within the UK and Internationally. Currently over 14,300 Internet sites have been identified and indexed for this service. This paper describes the infrastructure which has been developed for the European gateway and the benefits it can offer to linked services within a single nation, or across Europe. The virtual technology park infrastructure developed in CONNET provides for user identification, centralised user profiling and profile management, automated and periodic user profile servicing, classification system management and mapping, discussion groups, secure communication and service validation, etc. The way in which these technology park services are able to be used and adapted in independent, but linked, national services is highlighted in the paper. The five individual services are also described briefly, highlighting the benefits they offer to the European construction industry and the possibilities they offer in terms of ensuring national services are inter-operable across all of Europe."
