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.

A three level approach for exploring the ICT impact on the building design process applied to a real-life project

Abstract: An understanding of how ICT impact on the building design process and the architect's role and contribution within it can be crucial for the building project success. This paper introduces a possible approach of organizing and structuring design process actions and roles, and how ICT impact on them. This approach is based on the definition of three building project levels and could contribute to a better overview of how ICT impact on the building design process and on the architect's role and contribution. The aim of this paper is to illustrate how this approach can be used to explore the ICT impact on a real-life project.

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.

Assessment of Impacts of Project Technical Complexity on Building Production Using Clustering and Knowledge-Based System

Abstract: Site production layout planning is highly correlated with the technical complexity of a building project. Building structures, building layouts, scales of project and external site conditions are the major components affecting allocation and positioning of site facilities and construction plant. The relationships between these attributes are well known by experienced project managers. In the planning and tendering process, project managers and planners would assess and decide the site production layout by applying their cognitive knowledge using intuitive rather than quantitative approaches. They recognize the benefit of using quantitative models in decision making, which however present much difficulty when modeling the intwined and complex relationships between large numbers of variables. This study proposes an assessment model to examine impacts of technical designs, building layout designs and site conditions on building production with respect to the site layout plan using a data-based platform, which can assist decision making in site planning.The system consists of two components, the Building Production Impact Assessment Model (BPIA) and the Building Production Impact Database (BPIDB). The BPIA adopts the natural clustering technique, the self-organizing Map (SOM), to classify building project samples in terms of technical complexity to compute the technical complexity index for the sample projects. The sample projects and their index are uploaded to the BPIDB forming the data records. In the assessment platform, planners can input the project information of a new project, and the system will return with a complexity index and three sample projects with the highest similarity. The objective of the proposed system is to generate both a quantitative complexity index derived by the clustering model and the cognitive knowledge through the selected projects to improve the quality of decisions. The conceptual framework of the system will be discussed and illustrated with examples.

Challenges and benefits of implementing virtual design and construction technologies for coordination of mechanical, electrical, and plumbing systems on a large healthcare project

Abstract: This case study presents the challenges that the project team faced and the benefits they realized in imple-menting virtual design and construction technologies to coordinate the Mechanical, Electrical and Plumbing (MEP) systems on a $95M healthcare project in Northern California, USA. These challenges include creating a work structure for the MEP coordination process, organizing the project team consisting of designers, engineers, contractors, and subcontractors, determining the handoff of information between the team members, creating guidelines for the most efficient use of virtual design and construction technologies, creating the process of conflict identification and resolu-tion between the MEP subcontractors, and aligning the contractual interests of the coordination team to meet the over-all project schedule. We also discuss the benefits that the project team achieved by using the virtual design and construction tools for the coordination of the MEP systems. These benefits include labor savings ranging from 20 to 30 % for all the subcontrac-tors, 100% pre-fabrication for the plumbing contractor, only one recorded injury throughout the installation of MEP systems over a 250,000 square feet project area, less than 0.2% rework for the whole project for the mechanical sub-contractor, zero conflicts in the field installation of the systems and only a handful of requests for information for the coordination of the MEP systems. The overall benefits to the owner include about 6 months’ savings on the schedule and about $9M in cost for the overall project.

Applying System and Requirement Engineering for Information Modeling in Infrastructure Projects

Abstract: The definition of LOD is currently subject of debate: Level Of Detail, Development, Definition, Information, etc. The question of the content of each LOD is generally discussed but much less the question of the real utility of these LOD. We first propose to apply system engineering on the whole project process documentation to identify the BIM uses scope. We then use requirement engineering to validate that modelling information is depending on requirement management. We complete this work with experimentation, applying system and requirement engineering on a specific system, longitudinal drainage system, defining this way a specific BIM use. This experiment complements our conceptual proposal for organizing process requirements related to project information management.

'Healer, heal thyself!': information management in an architecture faculty

Abstract: The architect’s profession has always been that of an organizer; a coordinator. In an increasingly specialized society such as ours there is an even greater demand for professionals with a wide range of management abilities. Today’s architect will have to organize and coordinate the flow, the means and the systematic storage of information in a project. For an institution that ‘produces’ architects, it is, in the opinion of the authors, vital to not only teach modern / contemporary methods of organizing information but also to practice them. If architecture students are to comprehend the necessity of organizing skills & tools, they will have to encounter these from day one of their student life. In 2002, the Faculty of Architecture of Aachen University (RWTH) reached a decision to provide all members of the faculty, teachers and students alike, with a central service for the management of information. That service, called RWTH Information Technology Assistant (RiTA) is to be a set of web-based tools for organizing and managing the curriculum and all matters connected to that. The objective of RiTA is to increase efficiency and transparency in the administration of the faculty.

An integrated decision-support system model for construction management executives

Abstract: In recent years, with the increasing popularity of the World Wide Web, integrated data management tools have enabled organizations to automate their management information systems. The application of information technology (IT) in the construction industry mainly involves planning, monitoring, reporting and similar managerial functions that, in unison, support effective decision-making. Istanbul Technical University's Project Management Center (ITU-PMC), was established as a research institution under the ITU Rectorate, with the main aim of planning, executing and controlling all construction projects within the university campus. One of the initial activities undertaken by the ITU-PMC, in enabling an efficient and effective management system was a research project concerning Management Information Systems for ITU Construction Projects. The objective of this project was to develop an integrated data management tool including decision-support utilities for communicating, organizing and managing project information using web-based technology and the network. This paper describes the model that was developed to enable the effective management of ITU's campus construction projects. The model entails an automated system for the effective management of multiple construction projects, enabling efficient budget utilization by offering an elaborate decision-support system for executive managers.

UNDERSTANDING ADOPTION AND USE OF ICT IN CONSTRUCTION PROJECTS THROUGH THE LENS OF CONTEXT, ACTORS AND TECHNOLOGY

Abstract: In the literature on construction related ICT no distinction is usually made between ICT use in the permanent organization and the temporary organization forming the building and construction projects. By drawing on the rich body of literature on organizational and managerial aspects of ICT the aim of the paper is to investigate how the interplay between contextual elements, actors’ frames of reference, and the ICT influence the adoption and use of ICT in building and construction projects. This objective will be pursued by an analysis of an ongoing study of ICT use in the Swedish building and construction sector, including semi-structured interviews and an ethnographic inspired study of a partnering project worth 50 million €. It is concluded that project based mode of organizing, with the prime focus on time and costs, creates a conflict with the process of introduction and development of ICT use that is characterised by ambiguity and indefinite duration in time that goes beyond the termination of a project. Unless immediate benefits are perceived by the adoption and use of an ICT application, it will not be used. This conflict can probably not wholly be solved, instead the industry has to learn to live with it and create spaces for innovation of ICT-mediated changes.

Organizing the information flow within a planning team: experiences, problems and solutions from a practically-oriented R&D-project

Abstract: Within the scope of the research project "Virtual Technology Park - Resource Saving inConstruction" a new approach was developed to reduce resource consumption (materials, energy,money) over the lifetime of a building. Furthermore, flexibility in planning should increase byimplementing combined organizational and technical measures to improve information flow duringthe planning process.To reach this goal, appropriate tools are needed: content-related, on the organizational level, andsupported by an "enabling infrastructure". The respective project results are a computational modelto assess the resource consumption for a building over its lifetime, an Information DependencyMatrix to improve project manageability, and employment of a document management system tofacilitate data exchange and co-ordination between project members.
