Information retrieval - a concept of an engineering database server for prefabricated elements

Abstract: A concept for an engineering database server for retrieving information on the use of prefabricated elements will be discussed. The methods for the re-use of design solutions stored in this structural library are based on database technologies for a client-server architecture and advanced concepts of object-oriented modelling techniques. The objective is to optimise the cognitive effort in the early design stage by actively supporting the choice and adaptation of a structural solution depending on the constraints of the design situation. Because of the great number of prefabricated concrete slab floors used in construction we have chosen this very promising domain to demonstrate our model.

Augmenting design integration and communication using idiom

Abstract: This paper discusses how a system developed for spatial composition using cases is able to improve design integration and communication. Layouts are built interactively by users rather than automatically generated as has been proposed by others. The design is incrementally parameterized as cases are added and therefore, case adaptation, user interpretation and model activation can occur at any stage. IDIOM supports designers through reducing constraint complexity and through managing design preferences, thereby restraining proposed solutions and further adaptation during subsequent project stages within globally feasible design spaces. Since this system finds global solutions for constraints in an incremental manner, it is well suited for collaborative design and for increasing the integration of spatial design with other activities. Practical applications, currently under way, are demonstrating the advantages of IDIOM for communication and integration in construction.

Toward Adaptive Context-Aware User Interfaces for Better Usability and Productivity in AEC Collaborative Tasks

Abstract: The Architecture, Engineering and Construction (AEC) sector gathers a wide range of stakeholders, roles and activities which may be performed in heterogeneous contexts. By “context”, we mean not only the environment and user’s particularities but also the “cooperation context” associated to the activity to be carried out. The activity in the AEC projects is highly collaborative, particularly uncertain and takes place in a continuously changing “cooperation context” (e.g. due to new plans, new stakeholders, problems on site, etc.). The activity is also characterized by a strong mobility (e.g. workers on the building site) which implies information availability issues. Therefore, we suggest in this paper considering new potential of context-aware technologies to support AEC business tasks. Interactive systems proposed for the sector do not usually address the usability issues implied by the various context changes. So, this paper introduces the use of Adaptive User Interfaces (AUI) for the AEC activity. AUI are particular context-aware applications capable of adapting themselves relevantly to the current context in order to better fit the ongoing task and users. To this purpose, it is firstly required to identify the particular AEC context properties and to characterize them. Based on a state of the art, we propose a classification of contextual information relative to the collaborative aspects. We then suggest reviewing AUI and focusing on their principles and capacity to improve visualization and interaction according to the user’s task. Many technical approaches exist such as the Model-Driven Engineer methods which we cover through a state of the art of AUI systems. Finally, we identify the potential usability and productivity benefits to apply AUI to common AEC tasks. For instance, we consider throughout this article, the cases of construction site meeting and inspection reporting. These two cases are good examples of context variability, both organizational and environmental.

Structuring Technical Guidelines in Fire Protection Engineering with Topic Maps

Abstract: Due to the federal structure of Germany and the continuous adaptation of engineering standards in the field of fire protection, there is a multiplicity of complex and heavily interrelated laws, technical guidelines, rules and regulations. This poses a challenge for all actors in the building planning process because for every trade structural fire protection aspects have to be considered.
