This paper describes a research project that addresses the difficulties in dealing with regulatory documents such as national and regional codes. These documents tend to be voluminous, heavily cross-referenced, possibly ambiguous and even conflicting at times. There are often multiple documents that need to be consulted and satisfied; however it is a difficult task to locate all of the relevant provisions. In addition, sections dealing with the same or similar conceptual ideas sometimes lay down conflicting requirements. We propose a framework for regulation representation, analysis and comparison with emphasis on the extraction of similarities between provisions. We focus on accessibility regulations, whose intent is to provide the same or equivalent access to a building and its facilities for disabled persons. An XML regulatory repository is developed to extract structural as well as non-structural features from government regulations to help user understanding and computational analysis. A similarity analysis is performed between different sources of regulations. In order to achieve a better comparison between provisions, we employ a combination of feature matching and structural analysis. Results are shown on comparisons between American and European codes, as well as on the domain of electronic-rulemaking.
A/E/C Team members, while collaborating on building projects, rely on past experiences and content through the use of project design archives (whether in paper or digital format). This leads to underutilization of potential knowledge, as decision-making of data, information, and knowledge reuse is limited by access to these archives, due to sheer size and inconvenient presentation. This paper presents an integrated solution that leverages two technologies CoMem (Corporate Memory) and iRoom (interactive Room) developed at Stanford. This addresses critical limitations, i.e., content, context, visualization and interactivity, constraining the process of collaborative exploration towards knowledge reuse and decision-making.
Construction is a conservative industry that over the last twenty ye ars has experienced drastic changes in the way that interdisciplinary teams interact to design and execute a project. In this article we offer a general overview of how the main participants cooperate in the different phases of a construction project, and which are some of the main areas for communication improvement. We also explore the communication tools used in the exchange of information, and identify the main causes of information breakdown. The general framework of this study is of application to both standard and green projects. At the end of the article we discuss the peculiarities of green buildings. Our goal is to offer a series of industry insights derived from the perspective of a general contractor aimed at identifying the areas where contributions in computing and information exchange could have a greater impact on the successful completion of a project.
An important feature of the 2003 SARS outbreak in Canada, Singapore, and Hong Kong was that many health care workers (HCWs) developed SARS after caring for patients with SARS. This has been ascribed to inadequate or ineffective patient isolation. However, it is difficult for dense cities to provide sufficient isolation facilities within a short period of time. This has raised concerns from the public for new strategies in the planning and design of isolation facilities. Considering that SARS or other infectious diseases could seriously damage our society’s development, isolation facilities that could be rapidly and economically constructed with appropriate environmental controls are essential. For this reason, the design team of the Department of Architecture collaborated with a special task force from the Faculty of Medicine, who are the frontline medical officers treating the SARS patients, to design Rapidly Assembled Isolation Patient Wards. Both architecture and medicine are well established disciplines, but they have little in common in terms of the mode of knowledge construction and practice. This induced much intellectual exploration and research interest in conducting this study. The process has provided an important reference for cross disciplinary studies between the architectural and medical domains.
Spatial data acquisition, integration, and modeling for real-time project life-cycle applications
(2004)
Current methods for site modeling employs expensive laser range scanners that produce dense point clouds which require hours or days of post-processing to arrive at a finished model. While these methods produce very detailed models of the scanned scene, useful for obtaining as-built drawings of existing structures, the associated computational time burden precludes the methods from being used onsite for real-time decision-making. Moreover, in many project life-cycle applications, detailed models of objects are not needed. Results of earlier research conducted by the authors demonstrated novel, highly economical methods that reduce data acquisition time and the need for computationally intensive processing. These methods enable complete local area modeling in the order of a minute, and with sufficient accuracy for applications such as advanced equipment control, simple as-built site modeling, and real-time safety monitoring for construction equipment. This paper describes a research project that is investigating novel ways of acquiring, integrating, modeling, and analyzing project site spatial data that do not rely on dense, expensive laser scanning technology and that enable scalability and robustness for real-time, field deployment. Algorithms and methods for modeling objects of simple geometric shape (geometric primitives from a limited number of range points, as well as methods provide a foundation for further development required to address more complex site situations, especially if dynamic site information (motion of personnel and equipment). Field experiments are being conducted to establish performance parameters and validation for the proposed methods and models. Initial experimental work has demonstrated the feasibility of this approach.
For planning in existing built contexts, the building survey is the starting point for initial planning proposals, for the diagnosis and documentation of building damages, for the creation of objectives catalogues, for the detailed design of renovation and conversion measures and for ensuring fulfilment of building legislation, particularly by change of use and refitting. An examination of currently available IT-tools shows insufficient support for planning within existing contexts, most notably a deficit with regard to information capture and administration. This paper discusses the concept for a modular surveying system (basic concept, separation of geometry from semantic data, and separation into sub-systems) and the prototypical realisation of a system for the complete support of the entire building surveying process for existing buildings. The project aims to contribute to the development of a planning system for existing buildings. ...
The contribution describes the didactical integration of wireless access networks for the campus of the University of Karlsruhe in the education of architects and engineers. It focuses on the development of an interdisciplinary communication network to encourage and promote the communication and collaboration between students. The project assumes that significant learning progresses in net-based learning scenarios are based upon the synchronous and asynchronous cooperation between the students themselves. The remote cooperation across borders of disciplines makes high demands on capacity in communicating and cooperating of the involved persons as well as on the supporting tools. Therefore, the collective acquisition of knowledge and cooperation has to be trained intensively during the studies. Based on the design and project oriented cooperation platform netzentwurf.de the authors developed the tools “Jobadmin“ to administrate multidisciplinary workgroups, the “Swarm Knowledge Catalogue“ to collect and store knowledge and “LivingCampus“, an instrument providing basic services for dynamic communication.
Three-dimensional models of urban objects play an important role in the urban applications such as urban planning, environmental concerning, or urban disaster mitigations. While the modeling of urban objects is time consuming and storage costing. This paper presents solutions for this. Buildings with regular shapes and plane roofs are constructed into computer models by identifying of graphic elements from the digital maps of urban area to get building base plane and building heights. Buildings with irregular shapes and non-plane roofs are constructed into computer models by employment of a specific system developed by the authors. Road objects and topologies are constructed into computer models by employment of specific algorithms. The solutions presented in this paper has been used in the development of urban disaster mitigation system for Shantou, China.
The construction management has been under pressure to reduce operating costs and to improve productivity using innovative information technologe (IT) solutions conformed to structural characteristics, site conditions and past experiences. Given the growing emphasis on effectiveness and efficiency in construction projects, there is an imminent need to develop a formal procedure to select the best IT application for each proposed construction project and research and development (R&D) project. As there are numerous factors that have to be considered in selecting appropriate IT in a given situation, decision-makers need to have multicriteria decision-making ability. To enable them to make the most appropriate decision in any situation, it is important that effective tools incorporating multicriteria decision-making techniques are available. In this paper, an Analytic Network Process (ANP) model is conducted for the selection of appropriate IT application for innovative construction management prior to construction or research. The paper concludes that the ANP is a viable and capable tool for conducting IT application selection in multicriteria decision-making environment.

Re-using knowledge in architecture, engineering and construction (AEC) firms can lead to greater competitive advantage, improved designs, and more effective management of constructed facilities. This paper discusses the importance of exploration and discovery of reusable knowledge from a corporate archive as opposed to simple search and retrieval. We describe and illustrate through a scenario of use an exploration framework and prototype, CoMemTM that formalizes the added value of exploration in the process of knowledge reuse. We discuss two exploration activities: (i) Breadth- Only overview exploration that assist a user to rapidly localize pockets of re-usable knowledge from the large corporate archive and (ii) Iterative breadth-depth exploration that enables a user to identify those re-usable components of the Corporate Memory that may yield design issues that were not originally considered.
The research reported in this article was conducted to mainly explore the two common numeric prediction techniques, the model tree and the regression tree, when used in conjunction with bagging as a wrapper method. Bagging is used to improve the prediction accuracy of these two algorithms, and results are compared with the ones obtained earlier by the k-nearest neighbor (KNN) algorithm. From the conducted experiments, both the bagged regression tree and bagged model tree produce better results than not only their corresponding regression tree and model tree alone, but also the KNN with optimal value of k equal to 7. In addition, the bagged model tree yields the lowest prediction errors and a highest correlation coefficient of 0.81. It is demonstrated that it is feasible to use the bagged model tree for engineering applications in prediction problems such as estimating the remaining service life of bridge decks.
This paper describes the concept, implementation and application of the Web-based Information System ‘Turtle’ for data monitoring, analysis, reporting and management in engineering projects. The system uses a generalised object-oriented approach for information modelling of physical state variables from measurements and simulations by sets of tensor objects and is implemented platform-independently as a Web application. This leads to a more flexible handling of measurement and simulation information in distributed and interdisciplinary engineering projects based on the concept of information sharing. The potential and advantages of Web-based information systems like ‘Turtle’ are described for one selected application example: a measurement programme dealing with the physical limnology of Lake Constance.
Some key facts about the economic environment of construction industry are explained. It is shown that construction industry is very heterogeneous and has changed drastically during the recent years due to a rapidly moving commercial environment. Two examples of todays’s use of virtual construction tools in construction projects are presented. The first example is the document control for a large international project. The second is the application of 4D modelling in the preconstruction phase of a dam project. It is shown that virtual construction, is a major international trend that currently takes up speed. Some generic industry needs for Research and Development which aims at short and medium term results are presented.
This paper introduces the current development of electronic catalogues of construction products. The common system architecture of Web-based electronic products catalogues are discussed, followed by a discussion on construction products information standardization and latest distributed-systems technologies for communicating construction products information. Finally, this paper presents an implementation of Web service in e-commerce systems to enable sharing of construction products information.
Beside the standard calculation programs for civil engineering buildings mathematical programs have been lately established for the solution of differential equations for the analysis of mechanical and static systems. Programs like Maple, Matlab, MathCAD and Mathematica are popular in this field. To the knowledge of the authors, the widest application functionality offers the program Maple. Its advantages are, e.g. the alternatively symbolic or numerical solution of differential equation systems, the easy handling of parameter studies, the immediate visualization of results, the definition of macros for selected calculation steps and their export in other computer languages and, not least, the automatically generated, very clear documentation of the matehematical calculus.
Building project, with many different players involved, requires open and commonly accepted standard for product model description. Product model based design tools support easy comparisons of design alternatives and optimisation of design solution technical quality. This supports client s decision-making and design target comparisons through the whole building project. Use of product models enable these tasks to meet both schedule and cost requirements Olof Granlund is using product models and interoperable software as the main tool in projects. The use and the realised benefits are illustrated by examples from 3 different real projects: University building, where product models were used already in the very early phases by the whole design team. Office building for research organisation, where product models were used in so called self-reporting building system. Headquarters for international company, where product models were widely used for building performance analysis and visualisations in design phase as well as for facilities management system configuration for operational phase.
With the speedy development of transportation of China, especially construction of many high-grade highways, some information technology successes have been achieved in the highway and bridge engineering, such as survey, design, construction and maintenance etc. In this paper, some applications about information technology in the highway engineering were introduced and some bridge professional software developed by RIOH (Research Institute Of Highways) in recent years was also introduced.
On Computer-Aided Instruction Tools for Teaching College Engineering Mechanics Related Courses
(2004)
In this research, questionnaires are designed to survey among teachers and students the current situation of applying Computer-Aided Instruction (CAI) tools to teaching and learning of college engineering mechanics related courses in Taiwan. The needs for CAI tools for teaching these mechanics related courses are investigated in the survey. Several prototypes of interactive multimedia tools are designed and implemented using information technologies. The applicability and effectiveness of these tools on assisting teaching of engineering mechanics related courses are discussed and evaluated. Moreover, a website for managing and sharing collected and developed CAI resources is constructed.
The contribution introduces an adaptable process model to meet the special requirements of the coordination of planning activities in AEC (Architecture, Engineering, Construction). The process model is based on the concept of Coloured Petri-Nets and uses metainformation to characterize process-relevant information and to enable process-control based on the actual results of the planning.
In this contribution, the design of an analysis environment is presented, that supports an analyst to come to a decision within a gradual collaborative planning process. An analyst represents a project manager, planner or any other person, involved in the planning process. Today, planning processes are managed by several geographically distributed planners and project managers. Thus, complexity of such a process rises even more. Prediction of consequences of many planning decisions is not possible, in particular since assessment of a planning advance is not trivial. There have to be considered several viewpoints, that depend on individual perceptions. In the following, methods are presented to realize planning decision support.
Building activities in the construction industry in Germany increasingly concentrate on building measures in or involving the existing built environment. Before planning can begin, buildings must be surveyed in whole or in part with the surveying of geometric data playing a dominant role. The geometric survey is typically undertaken using geodetic or photogrammetric measuring techniques and equipment that have been adapted for use in building surveying. Accordingly appropriate technical knowledge is required in order to be able to operate them as well as a considerable financial investment. Such equipment and surveying methods are usually adaptations from other disciplines. The paper discusses and presents approaches to developing “new” equipment for building surveying, devised with the needs of building surveying in mind – redesigns or new designs for surveying tools. The designs are the result of an inter-disciplinary project between the Faculty of Architecture and the Faculty of Product Design at the Bauhaus Universität Weimar.
This paper deals with two different agent-based approaches aimed at the incorporation of complex design information into multi-agent planning systems. The first system facilitates collaborative structural design processes, the second one supports fire engineering in buildings. Both approaches are part of two different research projects that belong to the DFG1 priority program 1103 entitled “Network-based Co-operative Planning Processes in Structural Engineering“ (DFG 2000). The two approaches provide similar database wrapper agents to integrate relevant design information into two multi-agent systems: Database wrapper agents make the relevant product model data usable for further agents in the multi-agent system, independent on their physical location. Thus, database wrapper agents act as an interface between multi-agent system and heterogeneous database systems. The communication between the database wrapper agents and other requesting agents presumes a common vocabulary: a specific database ontology that maps database related message contents into database objects. Hereby, the software-wrapping technology enables the various design experts to plug in existing database systems and data resources into a specific multi-agent system easily. As a consequence, dynamic changes in the design information of large collaborative engineering projects are adequately supported. The flexible architecture of the database wrapper agent concept is demonstrated by the integration of an XML and a relational database system.
The paper presents the abstraction of process relevant information in order to enable the workflow management based on semantic data. It is shown for three examples, how the standards define the information needed to perform a certain planning activity. Abstraction of process relevant information is discussed for different granularities of the underlying processmodel. As one possible application ProMiSE is introduced, which uses process relevant data in individual tokens in a petri-net based process-model.
Building design in Civil Engineering is characterized by the cooperation of experts in multiple disciplines. Close cooperation of engineers in different fields is the basis of high product quality, short development periods and a minimum of investment costs. For each building the engineers have to create a new fire engineering model. The consistent realization of the fire engineering model in all details has high demands on communication, collaboration and building models. Thereby, to preserve the related design models consistent to each other and compatible with the rules of fire engineering is a complex task. In addition, regulations and guidelines vary according to the building location, so the knowledge base must be integrated dynamically into the planning process. This contribution covers the integration of engineers and design models into a cooperation network on the basis of mobile agents. The distributed models of architectural design, structural planning and fire engineering are supported. These models are implemented as XML-based models which can be accessed by mobile agents for information retrieval and for processing tasks. Agents are provided to all planners, they are enabled to check up the distributed design models with the knowledge base of the fire protection regulations,. With the use of such an agent each planner is supported to check up his planning for accordance with the fire protection requirements. The fire-engineering-agent analyzes the design and detects inconsistencies by processing fire protection requirements and design model facts in a rule-based expert system. The possibility to check the planning information at an early state in the sense of compatibility to the fire protection regulations enables a comprehensive diagnosis of the design and the reduction of planning errors.
The contribution introduces a method for the distributed process modelling in order to support the process orientation in Structural Engineering, i.e., the modelling, analysis and management of planning processes. The approach is based on the Petri Net theory for the modelling of planning processes and workflows in Structural Engineering. Firstly, a central and coarse process model serves as a pre-structuring system for the detailed modelling of the technical planning activities. Secondly, the involved planning participants generate distributed process models with detailed technical workflow information. Finally, these distributed process models will be combined in the central workflow net. The final net is of great importance for the process orientation in Structural Engineering, i.e., the identification, publication, analysis, optimization and finally the management of planning processes.
Cost and Schedule Controlling in Relation to Liquidity Management during Construction Projects
(2004)
The present paper describes a software application which can be used for relating the scheduled events of a construction project with the respective financial parameters, leading to an overall improvement in general controlling and liquidity management. For this purpose, existing construction schedules are taken and details of the assignment are recorded. Thus it becomes possible to assess a future payment status should changes in the designated schedule occur.
The increasing demands in building and civil engineering – with regard to the growing amount of legal requirements and the needs of a flexible usage of the building - requires an optimisation of all processes during the planning and construction phases. This aim can be only reached by transferring of innovative information and communication technologies in the field of cooperation of all partners in a building project. In this article the enhancement of the existing planning processes based on an improved information management is introduced. Since the late 90ies the availability of hardware and software infrastructures for a networkbased cooperation, e.g. email, in small and middle-sized companies increased the problems of an unstructured communication in the planning and construction processes. These problems have not been solved by the usage of the upcoming project communication systems either, which are often used as a simple medium for data transfer. Because of the easy way of distributing documents to all planning partners a huge amount of files and subsequent versions can be stored so that the planners often have to scope with an information overflow. The underlying hierarchical structures based on simple files stored in tree views are not sufficient for an adequate representation of the different specific views of the planners and the management of relationships between the three information domains building structure, costs and time schedules. ..
Die Planung komplexer Bauwerke erfolgt zunehmend mit rechnergestützten Planungswerkzeugen, die den Export von Bauwerksinformationen im STEP-Format auf Grundlage der Industry Foundation Classes (IFC) ermöglichen. Durch die Verfügbarkeit dieser Schnittstelle ist es möglich, Bauwerksinformationen für eine weiterführende applikationsübergreifende Verarbeitung bereitzustellen. Ein großer Teil der bereitgestellten Informationen bezieht sich auf die geometrische Beschreibung der einzelnen Bauteile. Um den am Bauprozess Beteiligten eine optimale Auswertung und Analyse der Bauwerksinformationen zu ermöglichen, ist deren Visualisierung unumgänglich. Das IFC-Modell stellt diese Daten mit Hilfe verschiedener Geometriemodelle bereit. Der vorliegende Beitrag beschreibt die Visualisierung von IFC-Objekten mittels Java3D. Er beschränkt sich dabei auf die Darstellung von Objekten, deren Geometrie mittels Boundary Representation (Brep) oder Surface-Model-Repräsentation beschrieben wird.
Die Planung von komplexen Bauwerken erfolgt zunehmend mit Planungswerkzeugen, die den Export von Bauwerksinformationen im STEP-Format auf Grundlage der IFC (Industry Foundation Classes) erlauben. Durch die Verfügbarkeit dieser Schnittstelle ist es möglich, Bauwerksinformationen für die weiterführende Verarbeitung zu verwenden. Zur Visualisierung der geometrischen Daten stehen innerhalb der IFC verschiedene geometrische Modelle für die Darstellung von Bauteilen zur Verfügung. Unter anderem werden für das „Ausschneiden“ von Öffnungen aus Bauteilen (z.B. für Fenster und Türen) geometrische boolesche Operationen benötigt.
Gegenstand des Beitrags ist die Vorstellung eines Algorithmus zur Berechnung von booleschen Operationen auf Basis eines triangulierten B-Rep (Boundary Representation) Modells nach HUBBARD (1990). Da innerhalb von IFC-Gebäudemodellen Bauteile oft das Resultat mehrerer boolescher Operationen sind (z.B. um mehrere Fensteröffnungen von einer gegebenen Wand abzuziehen), wurde der Algorithmus von Hubbard angepasst, sodass mehrere boolesche Operationen gleichzeitig berechnet werden können. Durch diese Optimierung wird eine deutliche Reduzierung der benötigten Berechnungen und somit der Rechenzeit erreicht.
One of the most promising and recent advances in computer-based planning is the transition from classical geometric modeling to building information modeling (BIM). Building information models support the representation, storage, and exchange of various information relevant to construction planning. This information can be used for describing, e.g., geometric/physical properties or costs of a building, for creating construction schedules, or for representing other characteristics of construction projects. Based on this information, plans and specifications as well as reports and presentations of a planned building can be created automatically. A fundamental principle of BIM is object parameterization, which allows specifying geometrical, numerical, algebraic and associative dependencies between objects contained in a building information model. In this paper, existing challenges of parametric modeling using the Industry Foundation Classes (IFC) as a federated model for integrated planning are shown, and open research questions are discussed.
IFC-BASED MONITORING INFORMATION MODELING FOR DATA MANAGEMENT IN STRUCTURAL HEALTH MONITORING
(2015)
This conceptual paper discusses opportunities and challenges towards the digital representation of structural health monitoring systems using the Industry Foundation Classes (IFC) standard. State-of-the-art sensor nodes, collecting structural and environmental data from civil infrastructure systems, are capable of processing and analyzing the data sets directly on-board the nodes. Structural health monitoring (SHM) based on sensor nodes that possess so called “on-chip intelligence” is, in this study, referred to as “intelligent SHM”, and the infrastructure system being equipped with an intelligent SHM system is referred to as “intelligent infrastructure”. Although intelligent SHM will continue to grow, it is not possible, on a well-defined formalism, to digitally represent information about sensors, about the overall SHM system, and about the monitoring strategies being implemented (“monitoring-related information”). Based on a review of available SHM regulations and guidelines as well as existing sensor models and sensor modeling languages, this conceptual paper investigates how to digitally represent monitoring-related information in a semantic model. With the Industry Foundation Classes, there exists an open standard for the digital representation of building information; however, it is not possible to represent monitoring-related information using the IFC object model. This paper proposes a conceptual approach for extending the current IFC object model in order to include monitoring-related information. Taking civil infrastructure systems as an illustrative example, it becomes possible to adequately represent, process, and exchange monitoring-related information throughout the whole life cycle of civil infrastructure systems, which is referred to as monitoring information modeling (MIM). However, since this paper is conceptual, additional research efforts are required to further investigate, implement, and validate the proposed concepts and methods.

In construction engineering, a schedule’s input data, which is usually not exactly known in the planning phase, is considered deterministic when generating the schedule. As a result, construction schedules become unreliable and deadlines are often not met. While the optimization of construction schedules with respect to costs and makespan has been a matter of research in the past decades, the optimization of the robustness of construction schedules has received little attention. In this paper, the effects of uncertainties inherent to the input data of construction schedules are discussed. Possibilities are investigated to improve the reliability of construction schedules by considering alternative processes for certain tasks and by identifying the combination of processes generating the most robust schedule with respect to the makespan of a construction project.
30. Forum Bauinformatik
(2018)
Die Bauhaus-Universität Weimar ist seit langer Zeit mit dem Forum Bauinformatik eng verbunden. So wurde die Veranstaltung 1989 hier durch den Arbeitskreis Bauinformatik ins Leben gerufen und auch das 10. und 18. Forum Bauinformatik (1998 bzw. 2006) fand in Weimar statt. In diesem Jahr freuen wir uns daher besonders, das 30. Jubiläum an der Bauhaus-Universität Weimar ausrichten zu dürfen und viele interessierte Wissenschaftler und Wissenschaftlerinnen aus dem Bereich der Bauinformatik in Weimar willkommen zu heißen.
