  abstract  = {The objective of the joint project 'Life cycle optimised system solutions for densified housing with massive wood technology', short form Basys, was the development and application of an open building system for sustainable construction in a virtual enterprise. Four partners coming from building economy and a university institute developed the building system in a comprehensive planning process. By applying massive wood technology, most requirements of densified housing can be met and individual buildings can be produced on demand.},

  abstract  = {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. ...},

  abstract  = {Buildings require both for construction and, due to their comparatively long life cycle for maintenance, significant raw material and energy resources. So far available knowledge about resource consumption during an entire life cycle of a building is still quite rare, because various criteria affect each other and/or overlay mutually. In this contribution a model based software concept is presented using an integrated approach for life cycle simulation and assessment of buildings. The essential point of the development consists of connecting an IFC compliant product model of a building via the Internet with data bases for the resource and energy requirement of building materials. Furthermore, numerical simulations allow calculating and minimizing the energy consumption, the resource requirement, the waste streams and also the noxious emissions. In the context of this paper we present the first release of software programs for architects and engineers, which help them to evaluate their design decisions objectively in early planning steps. Additionally the usage of the software is demonstrated by a test case study for a real world building. By applying this software in practice a substantial contribution for saving energy and natural resources can be provided in the sense of sustainable and ecological building design.},

  abstract  = {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.},

  abstract  = {The pavement is one of the basic components of road infrastructure and, therefore, directly influences general levels of transport safety, as well as the quality of transportation services in human and cargo traffic. It also exerts a major influence on the final logistic costs of production and services in many aspects of everyday life. The continuity of transportation, which is closely tied to the development of a number of areas in the economy of every State, depends on the technical condition of the road pavement. Making proper investments in the complete course of life of the road pavement, a policy which makes sure that the conditions for continuous, safe, efficient, and economically optimised transportation are satisfied, is a priority for every administration managing municipal funds. If investments in the road pavement are not carried out properly, there usually are more and more road pavements the condition of which causes delays in transportation, and directly compromises traffic safety. Such a situation increases the running costs of vehicles, and decreases the transportation service levels and comfort of travelling. At the moment, the majority of pavements in Europe, (nearly 90\% of all pavements) are flexible road pavements. Due to the prevalent number of flexible pavements in Europe, the author analyses investment in the course of full-time of life cycle of the pavements, with a stress on flexible pavements. The paper presents basic assumptions and definitions in the area of analysis of life cycle costs of a flexible road pavement, as well as profits associated with proper long range investment. The classification of damages to flexible road pavement has also been presented, and their influence on technical and use related assessment of road pavement conditions, basing on the traditional road pavement structures, with relation to the catalogue of typical flexible pavements used in Poland, as well as regarding French, British, and American experience in constructing long life road pavements. The second part of the paper discusses different investment strategies in the course of a full-time of life cycle of the road pavement, and proposes a procedure of evaluating investment strategies. The summary presents some assumptions for a global index of investment evaluation during the full-time of life cycle of a pavement, based on the Best Return Index (BRI).},

  abstract  = {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.},

  abstract  = {Anl{\"a}sslich der Bedeutung und Tragweite des Risikomanagements f{\"u}r die erfolgreiche Abwicklung von Public Private Partnership-Projekten wurde von Juni 2008 bis Oktober 2010 das Forschungsprojekt „Lebenszyklusorientiertes Risikomanagement f{\"u}r PPP-Projekte im {\"o}ffentlichen Hochbau" an der Bauhaus-Universit{\"a}t Weimar umgesetzt. Gef{\"o}rdert wurde das Forschungsprojekt aus den Mitteln der Forschungsinitiative „Zukunft Bau", welche durch das Bundesministerium f{\"u}r Verkehr, Bau und Stadtentwicklung (BMVBS) und dem Bundesamt f{\"u}r Bauwesen und Raumordnung (BBR) als Projekttr{\"a}ger gemeinsam durchgef{\"u}hrt wird. Das Ziel des Forschungsprojektes bestand in der Entwicklung eines Integrierten Risikomanagementsystems (abgek{\"u}rzt: IRMS), das die PPP-Vertragspartner zu einem zielgerichteten und wirtschaftlichen Umgang mit den inkludierten Risiken bef{\"a}higen soll. Dar{\"u}ber hinaus soll das System eine projektspezifische und innerhalb des gegebenen Handlungsspielraums optimale Risikoverteilung erm{\"o}glichen. Der Forschungsbericht untergliedert sich in vier Teile, welche die Arbeitsergebnisse des Forschungsprojektes strukturiert darstellen. Zun{\"a}chst werden im ersten Teil des Forschungsberichtes die Ergebnisse einer empirischen Untersuchung zum Ist-Zustand des Risikomanagements in PPP-Projekten des {\"o}ffentlichen Hochbaus als Grundlage f{\"u}r die weiteren Untersuchungen und Ergebnisse des Forschungsprojektes analysiert. Der zweite Teil des Forschungsprojektes beinhaltet ein Kompendium bzw. Werkzeugkasten der Methoden des Risikomanagements. In ihm werden die Verfahren zur Erlangung von risikobezogenen Erkenntnissen oder praktischen Ergebnissen dargestellt und hinsichtlich ihrer Eigenschaften analysiert. Dar{\"u}ber hinaus werden Allokationskriterien auf der Grundlage der den PPP-Vertragspartnern real zur Verf{\"u}gung stehenden Informationen definiert, die als Basis sowohl f{\"u}r die Selektion vorteilhafter Risikobew{\"a}ltigungsmaßnahmen als auch f{\"u}r den Nachweis der Vorteilhaftigkeit der {\"U}bernahme von Risiken f{\"u}r Auftragnehmer im Risikomanagementprozess dienen. Durch die Anwendung dieser Allokationskriterien im IRMS kann eine optimale Risikoverteilung sowohl f{\"u}r den einzelnen Projektpartner als auch das Gesamtprojekt erreicht werden. Im dritten Teil wird das integrierte Risikomanagement-Prozessmodell {\"u}ber den gesamten Projektlebenszyklus eines PPP-Hochbauprojektes unter Ber{\"u}cksichtigung der relevanten PPP-Vertragspartner dargestellt und erl{\"a}utert. Es stellt einen wesentlichen Beitrag zur Standardisierung dar und bietet die M{\"o}glichkeit f{\"u}r die Praxis, ein Verst{\"a}ndnis f{\"u}r die Abl{\"a}ufe und Anforderungen der anderen Vertragspartner weiter zu entwickeln. Das Modell besteht aus drei Ebenen. Auf der ersten Ebene werden die Prozesse aller PPP-Vertragspartner und ihre Interaktion {\"u}ber den Projektlebenszyklus in einer globalen Prozesslandkarte dargestellt. Die zweite Ebene bildet die vertragspartnerspezifischen Prozesslandkarten ab. Den h{\"o}chsten Detaillierungsgrad weist die dritte Ebene mit den vertragspartnerspezifischen Risikomanagementprozessen auf. Sie bildet die Integration der einzelnen Phasen des Risikomanagementprozesses in die bestehende Ablauforganisation der PPP-Vertragspartner in Form von Prozessflussdiagrammen ab. Von herausragender Bedeutung innerhalb des Risikoprozessmodells ist der Standardprozess Risikoallokation, welcher bei allen Vertragspartnern in den einzelnen Projektphasen verwendet wird. Abh{\"a}ngig von der jeweiligen Zielstellung seiner Verwendung bef{\"a}higt er sowohl zur Ermittlung der optimalen Risikoallokation unter dem gegebenen Handlungsspielraum des Anwenders als auch zur Auswahl einer optimalen Risikobew{\"a}ltigung f{\"u}r ein Einzelrisiko bzw. Risikob{\"u}ndel innerhalb eines bestehenden Steuerungskonzeptes. Der vierte Teil f{\"u}hrt die Erkenntnisse der vorhergehenden B{\"a}nde in der exemplarischen Ausgestaltung des IRMS zusammen. Es besteht aus dem auf die PPP-Prozesse abgestimmten integrierten Risikomanagement-Prozessmodell, den zu den einzelnen Prozessen geh{\"o}renden Methoden sowie organisationsspezifischen Festlegungen. Um die Anwendbarkeit eines solchen IRMS aufzuzeigen, wird exemplarisch die methodische Ausgestaltung des Standardprozesses Risikoallokation vorgestellt.},
