Abstract:
Logistical processes are an indispensable part of any construction process. Due to the complexity of logistical process chains, the modelling of logistical systems represents an important basis for process monitoring and control.
As an introduction to the topic, the relevant terms are clarified and historically classified. The importance of logistics in general is then highlighted.
The central aim of this thesis is to organise the project management of a construction company according to industrial standards.
The model is the modern production systems of the automotive industry. The technical possibilities of RFID have a high influence on logistics and are to be mentioned first. The documentation of the building materials and components used can be implemented in real time with this technology and improves a functioning exchange of information in the construction process. Parts of lean management, such as Just in Time and its application in the construction industry, are also explained. Due to the special features of the construction industry, the application is associated with difficulties. Individual tools of lean management are used in construction in a modelled form and optimise planning and execution. Work routines, standardisation and visualisation are then developed on the basis of the current status. The limits of transferability are characterised by capturing the differences in logistics processes in construction compared to stationary industry. High-quality models are essential in all areas of construction planning and execution. Therefore, Building Information Modelling (BIM) is considered as a future method. Using three case studies from civil engineering, road construction and a fire protection renovation, the utility value of introducing and using this method for those involved in the process is calculated and critically examined.
Against this background, relevant modelling variants are examined. In essence, it is a question of how a logistical process can be described and represented in the construction site environment. For this purpose, existing models such as SIPOC, flow diagrams, BPMN 2.0 and others are examined. In exemplary practical applications of these modelling variants, the possibilities and suitable procedures for increasing added value and supporting project management are demonstrated. Case studies for the modelling variants are typical material supply situations, for example with concrete components, steel deliveries, concrete delivery and concrete production. Based on the selected examples, comparisons are made and statements about the suitability and the advantages and disadvantages of these modelling approaches are summarised in a decision matrix.
