|Project title||Organization and control of construction site processes in modular building consolidation to optimize costs, time and resource efficiency (MoGeNa)|
|Project duration||01.11.2018 – 30.10.2020|
The increasing demand for affordable housing in major German cities is one of the most explosive political issues of the current era. Due to limited open spaces, the Modular Building Compaction represents a promising solution with high potential. The concept can be applied both to the closing of vacant lots and to the overbuilding of existing areas (e.g. parking lots). Standardized room modules are manufactured in advance in a "module factory" and installed just-in-time on the construction site.
The aim of the research project is to develop a method for the organisation and control of processes in MoGeNa, including the trades involved in the process (especially SMEs). In addition to the characterisation of modular construction sites and the identification of central influencing variables including existing interdependencies, the transfer of established production control procedures to the planning and control of construction projects forms the core of the method development.
The final aim is to implement the developed method in a software demonstrator in order to enable SMEs in particular to optimise the construction process and thus significantly reduce project costs.

Since free?aces for new buildings are limited or not available at all, redensification is a promising approach to generate new living space. This can be both the extension of existing buildings by further storeys and the vertical extension or change of use of other building structures. Modular house construction takes this objective into account because a large part of the added value is generated before construction begins. Its advantages are now set against the logistical challenges of post-densification.

On inner-city construction sites, there is usually only a limited amount of space available. This increases the complexity in the implementation of corresponding construction projects and at the same time the risk of postponements. Both the composition of the demand for specific types of space and the development of demand during the construction period should be taken into account in the course of scheduling. One way of assessing the demand for space is to introduce the potential for conversion as an indicator of the property of a specific space to be able to adapt flexibly in the event of possible short-term changes in the construction project. This can be used to create an evaluation basis that initially provides decision support for project planners and can subsequently be integrated into optimising procedures for scheduling. This will have a positive influence on the quality of a schedule in connection with its robustness.

Demographic change and the associated population growth in large cities make it increasingly difficult to create affordable housing. There is also a lack of available building land for potential new buildings. One approach to alleviate the housing shortage in large cities is modular building post-compaction. In this context, prevailing framework conditions are characterized by limited available space, a complex infrastructure or the consideration of the burden on residents. The lack of description models for associated construction sites, as well as for the organisation and control of necessary processes, still stand in the way of their widespread use. This refers in particular to the interactions of the parameters mentioned and their effect on the logistic performance of such a construction site. This article therefore describes a method for the organization and control of construction site processes in the modular building post-compaction with the aim to be able to plan and carry out such con-struction projects efficiently and with little effort. The users shall be provided with a process description of the planning of construction site equipment and process flow, as well as with a decision support in case of disturbances of the process in the operative operation.
