Deliverable 2.1

Building complex design matrix for each hazard scenario focussed on security effect solutions

Public report released


Executive Summary

Large scale buildings can be subject to a range of accidents, natural disasters or attacks. The impact of one of these “scenarios” is dependent on the magnitude of the event and the design of the building. In order to design safe buildings, the engineers must be aware of the possible hazards and the impact of these hazards to their building design. Deliverable 1.2 gives a clear overview of the hazard scenario to consider. This report describes the output of task 2.1 and deliverable 2.1.The objective of this deliverable is to provide a design matrix which shows engineers how a hazard scenario affects the building design regarding the architectural and structural elements and the building services.

In order to create a practical tool for engineers, it has been chosen to use the method of “system engineering”. This method is explained further in this report. Using the philosophy of this method the building has been defined by means of functions and objects/systems. The functions define the functional requirements of the Elasstic Building Complex. The objects and systems describe how these functional requirements are fulfilled. The objects and systems are defined by using the NL/SfB1 element classification system. This classification system assigns a unique code to every element in a building. This gives a clear structure and provides the means to realize “easy” coupling with BIM because every object has an unique code.

The definition of the building by functions and objects/systems is necessary to relate the impact of hazard scenarios to the design aspects of a building design. The scenarios are documented and quantified in deliverable D1.2. Within this report the scenarios are decomposed into consequences. One scenario will have several consequences on several building elements. By relating these consequences to the defined functions and objects/systems a design matrix is created which clearly shows how a hazard scenario has an impact on an object.

To store all data regarding scenarios, events, functions, objects and the relationship between these subjects a web based, commercial available, database tool is used. For this project “Relatics2” is used, this package is frequently used within Arcadis. This tool makes it possible to store all data in a structured way and realize the various relationships between scenarios/event on the one hand and the functions/objects on the other hand.

The tool Relatics has the potential to be used as an integral design tool which stores all relevant data for a project. It creates the possibility to define the whole building in functions, objects and specifications. Relationships within the database between functions, objects and specifications can be clearly defined. The tool can be used for constant tracking of the design process and verification of the design with the requirements. The use of this tool to the full extent is briefly described in this report but is at the moment not part of the Elasstic project. It has been limited to the extent of creating the design matrix.

After filling the database with all the information, two tools are created which can be used by other engineers. One tool is an interactive html based collapsible tree. Using this tree, the impact of a scenario on the building design is visibly structured. The second tool is an Excel spreadsheet. The spreadsheet shows the relationships between functions/object and the scenario/events.

This example shows the relation between the scenario “explosion, small inside the building” and the objects at the right side. The events are shown in the middle.

This deliverable provides engineers two tools which can help them to understand the impact of hazard scenarios on building design. The design matrix will be further developed during the Elasstic project. The matrix described in this report is a first draft. During the project new insights will be gained, which will then be incorporated into the design matrix. The intention is to extend this design matrix with design solutions. The matrix now only shows the impact on the design. However it is intended as part of Elasstic to define several design solutions for the objects which minimize the impact of the scenarios and events. These solutions will be incorporated into the matrix in a later stadium.

The database tool used to store all data proves to be helpful to structure all information and make interrelated connections between hazard scenarios and the diverse objects which are part of the building design. Because of this clear structure the Relatics database has the potential to exchange data with the BIM model of the building complex. This will have to be further investigated as part of WP 2. The goal will be to develop an optimal exchange in such a way that impact information will be shown in the BIM model.
