Industry Foundation Classes for Project Management - A Trial Implementation

Abstract: An effort is underway to develop Industry Foundation Classes--industry-standard data structures for exchanging information about construction projects. In addition to physical information about buildings, these classes represent project management information such as estimating and scheduling data. Many core concepts relating to the project management portions of the Industry Foundation Classes have recently been added to these models, but these have received virtually no testing and implementation to date. A workshop was held to work through an implementation and evaluation exercise for these models. The results identified many areas for potential improvement, but also confirmed that the overall approach taken by the models worked well for representing and integrating product, work process, estimating, and scheduling information.

From BIM Models to Integrated Energy Efficiency Applications for Industrial Facilities

Abstract: Raised interest in efficient use of available resources in industrial facilities prompts for software-tools to predict and manage energy demand of the whole system. An integrated approach considering all energy consumption contributors, classified into building, energy system, production and logistics, is developed within the research project Balanced Manufacturing (BaMa). Thereby BIM models of industrial spaces containing valuable information are used for creating a comprehensive representation of building-related aspects in a hybrid simulation environment, able to assess manufacturing and auxiliary energy demands.For testing the applicability of this integrated hybrid approach, a prototype is developed based on an actual use case. The simplification procedure is presented and the energy performance results are compared with that of an established building energy modelling software, discussing advantages and limitations. Essential information that needs to be transferred from the BIM model is clarified and prioritised.

CONCURRENT ENGINEERING IN EDUCATIONAL PROJECTS: CASE STUDY SVARTO_BERGET

Abstract: Each year, Lulea_ University of Technology teach 40 civil engineering students and 45 architectural engineering students basic knowledge in the construction process through a simulated real-life situation. In the third year, the grand total of 85 students is brought together and taught their respective professional roles through acting as experts within 6 different fields in the realization of a residential area. Research in the last decades has identified concurrent engineering as a possible method for streamlining the design phase in the construction process. The student project was therefore planned with a concurrent engineering approach, where all student groups start their work at the same time. The pedagogy was to teach students a new approach to working in large projects, with the side effect of testing if concurrent engineering is feasible also in educational projects.Information is shared between groups through live documents on a project portal. Project coordination and communication is handled by 21 project leaders who meet regularly to exchange information between groups and detect missing information needed from other groups. Project planning is made through a method adopted from lean construction; Look Ahead Planning, which is part of the Last Planner method. IT-support is used to produce data and perform calculations but also as a tool for quality assurance across groups. All data is eventually summed up and presented in a virtual reality model of the new residential area. The VR model is gradually refined and the structure for delivering information into the model is drawn up by 6 appointed IT coordinators.

Assessing the Effectiveness of Virtual Environments for Learningthe Fundamentals of Surveying and Construction Layout: Initial Findings

Abstract: The practice of Surveying and Construction layout is one of the fundamental skills that need to be acquired by an engineering or construction management student. Mastering these skills require extensive training with the equipment and team members in order to achieve both precision and accuracy in measurements. In additional to getting used to the equipments, the mastering of the technique requires the students to follow procedures accurately. This paper presents the results of testing a surveying and construction layout game. The game is a first step in a plan to develop a Virtual Reality VR surveying education tool, where students will practice by interacting with a real time computer generated imagery (CGI).The test involve students who have been enrolled in the surveying class for the spring semester 2010. The students are asked to perform a specific surveying task. The students attempts are documented based on their ability to follow the correct procedures and on their ability to choose the correct needed equipment. The paper will show the results of the students ability to follow the correct procedures needed to achieve the appropriate level of precision and accuracy. The results of this test will help make the case that Virtual Reality tools can reinforce the learning of hands on classes such is the case for Surveying and Construction Layout.

Documentation and data archival of civil infrastructure research using multimedia cd-rom

Abstract: The University of Cincinnati Infrastructure Institute (UCll) currently operates a decommissioned steel stringer bridge testbed site which is serving as the test specimen for researching and demonstrating condition assessment and structural damage detection concepts and tools. The research is designed around the iterative application of various damage scenarios followed by structural identification in order to determine the viability and sensitivity of various experimental approaches (including instrumented monitoring and modal testing) for use in objective condition assessment. This project constitutes a first of its kind attempt at the study of these methods applied under realistic damage conditions to an actual full-scale operating structure. As a result, the experimental data and results acquired during this research are potentially of great value members of the academic, government, and induslrial communities. Correspondingly, one of the goals of this research is the dissemination of results through the use of a CD-ROM multimedia database incorporating infomation in audio, video, photogrammetric, diagrammaticKADD, text, graphical, and raw numeric data formats. The goal of this effort is to effectively communicate to users all information about the project necessary to be able to make use of the experimental data and results obtained in an intelligent and informed manner. This paper describes various design and development issues connected with this database development effort.

Testing Semantic Interoperability

Abstract: With standardised semantic representations of construction objects able to be transferred between major CAD systems, and other design tools, there is an expectation, supported by compliance testing, that semantically consistent data will flow across the project team. This assumption is questioned due to the known difficulties in mapping consistently and completely between two distinct representations of an artifact. To test the ability of CAD, and design tools, a number of buildings, described in a standard format, are loaded and then saved directly back out of these tools and then checked for differences. A range of potential differences has been postulated, and experiments show the existence of most categories of differences when data files are examined.

Safety Training for Scaffolding and formwork Construction by Using Virtual Environment

Abstract: Scaffolding and formwork activities are the most frequent construction activities that exist in almost every construction project. Common site accidents such as falling from a height, formwork collapses frequently occur during these activities. Previous literature highlight that human-based factors are the major causes that lead to the scaffolding and formwork accidents. In this sense, safety training is crucial to prevent these accidents by improving the safety skills of trainees. Knowing that virtual technologies based trainings have a great potential to provide an effective training, we developed a virtual safety training tool called V-SAFE.v2 which simulates the scaffolding and formwork activities. V-SAFE.v2 supports both single and multi-user training scenarios. In the training stage, trainees interact with the autonomous agents to learn the essentials of the tool and the scaffolding and formwork construction skills. In the testing stage, trainees enter into the virtual environment to test their skills and safety knowledge that acquired during the training stage. Finally, trainees receive feedback based on their safety behavior at the end of testing stage. The preliminary results of this study demonstrate that V-SAFE.v2 is an effective safety training tool for the scaffolding and formwork activities.

DEVELOPMENT AND TESTING OF A PROCESS MATURITY MODEL IN THE DOMAIN OF INFRASTRUCTURE MANAGEMENT

Abstract: As information systems continue to expand their reach into the work process of the construction industry, communication and information exchange that traditionally occurs between humans is increasingly being replaced with automated or semi-automated information exchange between computer systems. These computer-based communications must be more formally defined and designed than the human-based communications that they replace. We are researching techniques to formally represent design information transactions within the construction industry. As part of this work, we are interested in assessing the degree to which information exchange processes are formalized and managed. This paper focuses on the development and application of an Infrastructure Management-Process Maturity Model (IM-PMM) to benchmark the degree of formalization of work and communication processes in the infrastructure management field. The proposed IM-PMM evolved through reviewing a set of relevant maturity models. It uses a scale of five levels of process maturity and is based on three core dimensions (process, actor role, and information definition) to benchmark work processes, plus one dimension (message definition) to benchmark communication processes. The proposed IM-PMM has been applied in the domain of infrastructure management and attempts to benchmark only the asset inventory and condition assessment reporting processes using researcher-administered structured interview approach. From the results of the survey, it is concluded that communication processes in the area of infrastructure management are typically accomplished in an ad hoc (undefined and unstructured) manner, emphasizing the need for improvement if advanced information systems are to be deployed to support efficient management of infrastructure systems.

Utilizing 4D Technology in Supply Chain Management

Abstract: During the last decade the role of technology in supporting the project execution and management has increased. However, the real impacts to supply chain have not been considered. This paper introduces a study utilising 4D technology for supply chain management. We explore how the interactive 4D application can be used for testing alternative supply chain scenarios. We describe experienced challenges when developing 4DLive Linker environment, which enables simulations of multiple scenarios in large construction projects. We demonstrate the research approach in a residential housing case that has two supply chain alterations. Our experiences show that decision making benefits from interactive environment. The end result enhances existing 4D applications to direction where alternative plans can be easily incorporated into applications, studied further interactively and presented in a communicative manner for decision making and construction site training.
