T1 - Supporting Domain Experts in Determining Viable User Interface Designs for Wearable Computers Used in AEC Work Situations N2 - The design of mobile IT systems, especially the design of wearable computer systems, is a complex task that requires computer science knowledge, such as that related to hardware configuration and software development, in addition to knowledge of the domain in which the system is intended to be used. Particularly in the AEC sector, it is necessary that the support from mobile information technology fit the work situation at hand. Ideally, the domain expert alone can adjust the wearable computer system to achieve this fit without having to consult IT experts. In this paper, we describe a model that helps in transferring existing design knowledge from non-AEC domains to new projects in the construction area. The base for this is a model and a methodology that describes the usage scenarios of said computer systems in an application-neutral and domain-independent way. Thus, the actual design information and experience will be transferable between different applications and domains.

A1 - Akinci, Burcu A1 - Wang, Hongjun T1 - Towards Domain-Oriented Semi-Automated Model Matching for Supporting Data Exchange N2 - The process of matching data represented in two different data models is a longstanding issue in the exchange of data between different software systems. While the traditional manual matching approach cannot meet today’s demands on data exchange, research shows that a fully automated generic approach for model matching is not likely, and generic semi-automated approaches are not easy to implement. In this paper, we present an approach that focuses on matching data models in a specific domain. The approach combines a basic model matching approach and a version matching approach to deduce new matching rules to enable data transfer between two evolving data models.

T1 - Issues in delivering it systems to field users N2 - IT support for field personnel is starting to appear on bridge inspection sites, construction sites, and on the manufacturing floor. ENR magazine now regularly advertises palm computing-based systems for recording data on a construction site. This support can, and should, take on many forms and functions and needs to be carefully designed and evaluated like any other important tool used in the field. With careful design and implementation, IT devices for the field should have tremendous impact on the productivity of field personnel. If the devices are not carefully designed to take account of the field context and the abilities and preferences of the field personnel, field workers will not use these tools.

T1 - An Approach for Planning Sensor-Based Inspection of the Built Environment N2 - The promise of lower costs for sensors that can be used for construction inspection means that inspectors will continue to have new choices to consider in creating inspection plans. However, these emerging inspection methods can require different activities, resources, and decisions such that it can be difficult to compare the emerging methods with other methods that satisfy the same inspection needs. Furthermore, the context in which inspection is performed can significantly influence how well certain inspection methods are suited for a given set of goals for inspection. Context information, such as weather, security, and the regulatory environment, can be used to understand what information about a component should be collected and how an inspection should be performed. The research described in this paper is aimed at developing an approach for comparing and selecting inspection plans. This approach consists of (1) refinement of given goals for inspection, if necessary, in order to address any additional information needs due to a given context and in order to reach a level of detail that can be addressed by an inspection activity; (2) development of constraints to describe how an inspection should be achieved; (3) matching of goals to available inspection methods, and generation of activities and resource plans in order to address the goals; and (4) selection of an inspection plan from among the possible plans that have been identified. The authors illustrate this approach with observations made at a local construction site.

A1 - Ries, R. T1 - Processing "fuzzy" materials sets for environmental impact analysis of buildings N2 - Processing technical and environmental data on building materials, components, and systems has become more important during the last few years. Increased sensitivity towards environmental and energy problems has lead to the demand for simulation and evaluation of the long term behavior of buildings. The results of such simulations are expected to enable architects and engineers to develop a broader, interdisciplinary understanding of the impact of their products (buildings) on the environment. However, conducting such evaluations is currently hampered by the lack of comprehensive, up-to-date, and ecologically relevant data on building materials, components, and systems. To address this problem, this paper proposes an approach to deal with the absent or uncertain attributes of building materials, components, and systems. In the past, various information systems have been developed to provide data on a limited set of building materials, including precise values pertaining to some of their characteristics, such as availability, manufacturers, costs, etc. These traditional information systems have difficulty in dealing with uncertain, incomplete and sparse data. However, uncertainty and incompleteness characterize the nature of most of the available and environmentally related characteristics of materials, components, and systems. In this paper, a fuzzy-logic-based augmentation of traditional information systems is proposed towards providing management, utilization and manipulation of incomplete and uncertain data.

A1 - Akinci, Burcu T1 - SiDaCoS: Product and Process Models on Construction Sites N2 - Site superintendents performing project management tasks on construction sites need to access project documents and need to collect information that they observe while inspecting the site. Often, information that is observed on a construction site needs to be integrated into electronic documents or project control systems. In the future, we expect integrated product and process models to be the medium for storing and handling construction project management information. Even though mobile computing devices today are already capable of storing and handling such integrated product and process data models, the user interaction with such large and complex models is difficult and not adequately addressed in the existing research. In this paper, we introduce a system that supports project management tasks on construction sites effectively and efficiently by making integrated product and process models accessible. In order to effectively and efficiently enter or access information, site superintendents need visual representations of the project data that are flexible with respect to the level of detail, the decomposition structure, and the type of visual representation. Based on this understanding of the information and data collection needs, we developed the navigational model framework and the application Site Data Collection System (SiDaCoS), which implements that framework. The navigational model framework allows site superintendents to create customized representations of information contained in a product and process model that correspond to their data access and data collection needs on site.

T1 - The preliminary design of a wearable computer for supporting Construction Progress Monitoring N2 - Progress monitoring has become more and more important as owners have increasingly demanded shorter times for the delivery of their projects. This trend is even more evident in high technology industries, such as the computer industry and the chemical industry. Fast changing markets, such as the computer industry, force companies to have to build new facilities quickly. To make a statement about construction progress, the status of a building has to be determined and monitored over a period of time. Depicting the construction progress in a diagram over time, statements can be made about the anticipated completion of the project and delays and problems in certain areas. Having this information, measures can be taken to efficiently >catch up< on the schedule of the project. New technologies, such as wearable computers, speech recognition, touch screens and wireless networks could help to move electronic data processing to the construction site. Progress monitoring could very much take advantage of this move, as several intermediate steps of processing progress data can be made unnecessary. The processing of progress data could be entirely done by computers, which means that data for supporting decisions can be made available at the moment the construction progress is measured. This paper describes a project, that investigates how these new technologies can be linked to create a system that enhances the efficiency of progress monitoring. During the project a first prototype of a progress monitoring system was developed that allows construction companies and site supervisors to measure construction progress on site using wearable computers that are speech controlled and connected to a central database via a wireless network.
