abstract: Emerging information and communication technology (ICT) has had an enormous effect on the building architecture, engineering, construction and operation (AECO) fields in recent decades. The effects have resonated in several disciplines, such as project information flow, design representation and communication, and Building Information Modeling (BIM) approaches. However, these effects can potentially impact communication and coordination of the virtual design contents in both design and construction phases. Therefore, and with the great potential for emerging technologies in construction projects, it is essential to understand how these technologies influence virtual design information within the organizations as well as individuals’ behaviors. This research focusses on understanding current emerging technologies and its impacts on projects virtual design information and communication among projects stakeholders within the AECO organizations. / Dissertation/Thesis / Doctoral Dissertation Civil and Environmental Engineering 2017

Globalisierung, gestiegener Konkurrenzdruck und ein effektiver Einsatz von Ressourcen zwingen die Unternehmen – nicht nur in der Automobilindustrie – zu einer permanenten Effizienzsteigerung im Entwicklungsprozess. Um schnell das optimale Design zu finden, kommen CAD- und CAE- Programme in einer frühen Entwicklungsphase des Bauteils zum Einsatz. Durch eine virtuelle Überprüfung und Verbesserung z.B. von Funktion, Gewicht und Lebensdauer können kostenintensive Prototypen und Versuche erheblich minimiert werden. In der Automobilindustrie rücken zudem akustische Eigenschaften immer mehr in den Fokus. Ein geringes Innenraumgeräusch oder der spezielle »Sound« eines Fahrzeuges sind klassenspezifische Qualitätsmerkmale, welche die Kaufentscheidung des Kunden stark beeinflussen (Zeller 2009). Bei der Konstruktion von Karosseriebauteilen muss dabei besonderes Augenmerk auf die Vermeidung von Resonanzeffekten gelegt werden. Moderne CAD-Programme – wie CATIA V5® der Fairma Dassault – bieten bereits die Möglichkeit im CAD-Workflow Bauteileigenschaften zu ermitteln. Somit verschmelzen zunehmend die Grenzen zwischen Berechnung und Konstruktion. Allerdings setzt jeder Teilbereich Erfahrung und Expertenwissen voraus, wodurch immer noch eine entsprechende Kaskadierung der Aufgaben im Entwicklungsprozess zu finden ist. Diese wird nachstehend erläutert.

Numerische Methode zur Bestimmung der Fahrwerkskonfiguration aus Baukastenkomponenten

Aus der Einleitung: "Qualität nimmt als Wettbewerbsfaktor eine immer größere Rolle ein. Damit wächst auch der Bedarf an schneller Messtechnik zur präzisen geometrischen Erfassung unterschiedlicher Werkstücke. Ein weiterer Grund für diesen steigenden Bedarf sind der zunehmende Automatisierungsgrad und die Fertigungsgeschwindigkeit in der Produktion (Pfeifer 1998). Der Vorteil der optischen 3D-Messung gegenüber konventioneller Koordinatenmesstechnik besteht vor allem in der höheren Erfassungsgeschwindigkeit. Taktile Messgeräte können im Vergleich nur sehr wenige Messpunkte in einer bestimmten Zeit digitalisieren, optische Messgeräte hingegen große Flächen in wenigen Sekunden (Berndt 2008). Des Weiteren ist die optische Messung im Gegensatz zur taktilen Messung berührungslos, wodurch Schäden am Werkstück oder direkte Einflüsse des Werkstücks (weiche Oberflächen) auf die Messergebnisse vermieden werden. In der Fertigungsmesstechnik kommen optische Verfahren vorwiegend zur Bestimmung geometrischer Kenngrößen wie Abstand, Form, Profil oder Oberflächenstruktur zum Einsatz (Pfeifer 1998). So können z. B. in der Automobilindustrie Blechbauteile auf Ihre Maßhaltigkeit hin untersucht werden."

abstract: At least 30 datacenters either broke ground or hit the planning stages around the United States over the past two years. On such technically complex projects, Mechanical, Electrical and Plumbing (MEP) systems make up a huge portion of the construction work which makes data center market very promising for MEP subcontractors in the next years. However, specialized subcontractors such as electrical subcontractors are struggling to keep crews motivated. Due to the hard work involved in the construction industry, it is not appealing for young workers. According to The Center for Construction Research and Training, the percentages of workers aged between 16 to 19 years decreased by 67%, 20 to 24 years decreased by 49% and 25 to 34 age decreased by 32% from 1985 to 2015. Furthermore, the construction industry has been lagging other industries in combatting its decline in productivity. Electrical activities, especially cable pulling, are some of the most physically unsafe, tedious, and labor-intensive electrical process on data center projects. The motivation of this research is the need to take a closer look at how this process is being done and find improvement opportunities. This thesis focuses on one potential restructuring of the cable pulling and termination process; the goal of this restructuring is optimization for automation. Through process mapping, this thesis presents a proposed cable pulling and termination process that utilizes automation to make use of the best abilities of human and robots/machines. It will also provide a methodology for process improvement that is applicable to the electrical scope of work as well as that of other construction trades. / Dissertation/Thesis / Masters Thesis Construction Management 2020
