Automated Generation of Construction Sequences using Building Information Models

Abstract

Construction scheduling is usually limited to the documentation of one final construction schedule, and construction alternatives that might have been considered during the planning process are usually not included in the final schedule. Moreover, a formal control of construction schedules in terms of completeness and correctness is very limited, because existing methods, such as 4D visualization, are insufficiently integrated into the construction planning process. This paper addresses the development of a software framework that has been designed to support the process of construction scheduling. As will be shown in this paper, the process of construction scheduling, which is usually carried out manually, is conducted automatically to a large extent using building information models (BIM) and 4D visualization. Due to the logical interconnections of BIM objects and construction tasks, flexible schedules and visual representations of construction processes are automatically generated without permanent human interaction.

BIMTakt – Optimierung der Produktionsplanung durch ganzheitliche Integration von BIM und Lean Construction

“…Diese Vorgehensweise wird in [17] verwendet, um verschiedene Ausführungsvarianten zu berücksichtigen. Die auf diese Weise generierten flexiblen Terminpläne können in einer Datenbank gespeichert und für zukünftige Projekte verwendet werden [18].…”

Research on Full-Element and Multi-Time-Scale Modeling Method of BIM for Lean Construction

“…Thus, it is paramount to maintain vigilant surveillance of the conditions throughout each phase of the construction's evolution, facilitating timely adaptations to an array of elements. This monitoring of conditions can be mathematically encapsulated in Equation (7).…”

“…Ma [6] pointed out that construction enterprises need to rebuild the model corresponding to construction activities as they cannot directly use the model information of upstream design units. In terms of 3D model element integration, Tauscher et al [7] pointed out that the lack of a fine classification of model elements would affect the generation of the construction schedule. Chau et al [8] divided the objects in the 3D model into structural elements (i.e., the main body of the building), operational objects (representing various activities performed on specific elements, such as formwork erection, etc.…”

O uso do BIM na elaboração de propostas técnicas de obras portuárias.

“…Estado atual e desafios do planejamento de obras O planejamento da construção é usualmente limitado à documentação de um cronograma final de construção, e alternativas que poderiam ser consideradas durante o processo de planejamento não são incluídas no cronograma final (TAUSCHER et al, 2014). Este cronograma final de execução, é baseado, primeiramente, em informações estáticas, conhecimento tácito, normas, políticas Com relação ao uso de equipamentos em obras, guindastes são equipamentos de construção corriqueiramente utilizados e o custo de sua utilização costuma ser bastante representativo.…”
