Beiträge zur 2. Fachtagung „Sicherheit auf Baustellen“ am Dienstag, dem 20. März 2001 in Weimar an der Fakultät Bauingenieurwesen, Professur Baubetrieb und Bauverfahren der Bauhaus-Universität Weimar. Der Tagungsband enthält einen Spezialteil „Qualität und Sicherheit auf Baustellen und im Schweißbetrieb“ anlässlich des Ausscheidens von Herrn Prof. Dr.-Ing. habil. Karl-Dieter Röbenack aus dem aktiven Berufsleben.
Jubiläumsbroschüre zum Tag des Baubetriebs >Prozesssteuerung-Projektleitung-Dienstleistung< am Freitag, dem 7. Juli 2000 in Weimar. Geleitwort des Rektors der Bauhaus-Universität Weimar 45 Jahre technologische Lehre und Forschung in Weimar Bauen im Jahr 2020 – Wohin verändert sich Baubetrieb? Statistische Übersichten
Die aktuelle demografische Entwicklung bedingt offensichtlich auch Arbeiten in rauer Umgebung bis zur Rente mit 67, auch auf dem Bau. Das Thema liegt scheinbar nur am Rande des Baubetriebswesens. Doch obwohl es sozialpolitisch determiniert ist, hat es sehr konkret mit Gesundheitsschutz, Arbeitsschutz und Arbeitsgestaltung zu tun. Die fünfte Fachtagung 'Sicherheit auf Baustellen' stellt sich der Diskussion, wie das Rentenalter gesund erreichbar ist, was alle am Arbeitsschutz Beteiligten schon heute und auch in Zukunft dafür tun können, und hinterfragt kritisch, wie realistisch diese pauschale Forderung nach Arbeit bis 67 ist. Forderungen nach schlankeren Strukturen im Staat und das Streben nach Deregulierung haben auch zu Veränderungen in der Arbeitsschutzverwaltung des Freistaates Thüringen geführt, über die das Forum informiert.
The aim of my research is to observe the variance of energy efficiency of a typical multi-story office building under the exposure of different climatic conditions. Energy efficiency requirements in building codes or energy standards are among the most important single measures for buildings’ energy efficiency. Therefore, this study can be set up for a better understanding of how energy efficiency of a building changes under the effect of adverse to moderate climatic conditions which possess a mentionable effect on the operation of a building.
This thesis is structured in three balanced and conceptual steps. Following the aim of the project, the virtual building model is to be analyzed under the effect of seven distinct climatic conditions namely work environment of New Delhi, Mumbai, Berlin, Lisbon, Copenhagen, Dubai and Montreal. Firstly, the task is to do a complete literature research based on the scope of similar researches and studying the problems in detail along with the theoritical background all the concepts which are implemented to get the numerical results. This chapter also comprises a detailed study of the climatic conditions of the above-mentioned cities. Different climatic traits like temperature variations, count of heating and cooling degree days, relative humidity, temperature range and comfort zonal charts for the specified cities are studied in detail. This study helps to understand the effect of these adverse to moderate climates on the operation of the building. On the second step, the virtual building model is prepared on a software platform named Revit Structures. This virtual building model is not necessarily a complete building, but it has the relevant functionalities of a real building. We perform the energy analysis and the heating and cooling analysis on this virtual building model to study the operational outcome of the building under different climatic conditions in detail. By the end of these above two tasks, two scenarios are observed. On one hand, we have a literature research and on the other hand we have the numerical results. Therefore, finally we present a comparative scenario based on the energy efficient performances of the building under such variant climatic conditions. This is followed by the prediction of thermal comfort level inside the building and it based on Fanger’s PMV Model. Understanding the literature and the numerical values in detail helps us to predict the index thermal comfort level inside the building.
The conclusion of this master thesis focuses mainly on the scopes of improvement of energy efficiency requirements in energy codes if any, differentiated according to specific locations. The initial aim of my hypothesis which is to study the impacts of climatic variations on the energy efficient performances of a building is fulfilled but as such topics have very deep and broad roots, the scope of further improvements is always predominant.
In recent years, the discussion of digitalization has arrived in the media, at conferences, and in committees of the construction and real estate industry. While some areas are producing innovations and some contributors can be described as pioneers, other topics still show deficits with regard to digital transformation. The building permit process can also be counted in this category. Regardless of how architects and engineers in planning offices rely on innovative methods, building documents have so far remained in paper form in too many cases, or are printed out after electronic submission to the authority. Existing resources – for example in the form of a building information model, which could provide support in the building permit process – are not being taken advantage of. In order to use digital tools to support decision-making by the building permit authorities, it is necessary to understand the current situation and to question conditions before pursuing the overall automation of internal authority processes as the sole solution.
With a substantive-organizational consideration of the relevant areas that influence building permit determination, an improvement of the building permit procedure within authorities is proposed. Complex areas – such as legal situations, the use of technology, as well as the subjective alternative action – are determined and structured. With the development of a model for the determination of building permitability, both an understanding of influencing factors is conveyed and an increase in transparency for all parties involved is created.
In addition to an international literature review, an empirical study served as the research method. The empirical study was conducted in the form of qualitative expert interviews in order to determine the current state in the field of building permit procedures. The collected data material was processed and subsequently subjected to a software-supported content analysis. The results were processed, in combination with findings from the literature review, in various analyses to form the basis for a proposed model.
The result of the study is a decision model that closes the gap between the current processes within the building authorities and an overall automation of the building permit review process. The model offers support to examiners and applicants in determining building permit eligibility, through its process-oriented structuring of decision-relevant facts. The theoretical model could be transferred into practice in the form of a web application.
Anlass zum Abriss der Brücke; Das abzubrechende Bauwerk; Vorgaben für den Abbruch (gemäß der Ausschreibung, aus statischer Sicht, aus Arbeitsschutzgründen); Abbruch der Aufbauten und der Fahrbahnplatte (Abbruch der Aufbauten, Problem Festpunkt Bogenscheitel – Fahrbahn, Abbruch Plattenbalken und Pfeilerscheiben); Abbruch der Bögen (Abbruchgerüst, Scheitelöffnung, Bogenrückbau, Kontrollsystem). Noch nie zuvor war in Deutschland eine Bogenbrücke auf diese Art und Weise abgebrochen worden. Maßgeblich für das Gelingen des schwierigen Rückbaus der Teufelstalbrücke war das Verantwortungsbewusstsein der Beteiligten im Zusammenhang mit der notwendigen Risikobereitschaft, aber auch mit der Vermeidung unnötiger Restrisiken schon von vornherein. Zur Risikominimierung trugen die gute Organisation des Vorhabens, regelmäßige gemeinsame Baustellenbegehungen mit Vertretern der für Sicherheit zuständigen Institutionen (Amt für Arbeitsschutz Gera, Bau-Berufsgenossenschaft, Sicher-heits- und Gesundheitsschutzkoordinator) sowie die technische Ausstattung bei. All dies führte letztendlich zum Erfolg einer Maßnahme, bei der man den bisherigen Erfahrungsbereich verlassen musste.
