+    "In this phase too several studies
+     have to be performed. The designer
+     makes several ‘structural’ concepts.
+     To make a sensible design, he
+     first analyses the force flow in both
+     horizontal and vertical direction. Also
+     the ability of the structure to retain
+     its shape and place is investigated
+     as well as the connections between
+     different elements and parts of the
+     building. After feedback from the
+     structural assumptions at least two of
+     the concepts are chosen for further
+     analysis. With the aid of design tools
+     (rules of thumb, diagrams and tables)
+     the overall dimensions of the structure
+     (including stability measures) are
+     determined and critical connections
+     are studied for feasibility. The
+     sections on different materials contain
+     information on structural elements
+     (such as precast conrete beams,
+     hollow core slabs etc.) and tables
+     with available (steel) profiles to come
+     to reasonable dimensions. Already
+     in this stage it is wise to orientate on
+     different foundation possibilities as the
+     foundation can have influence on the
+     rest of the structure. The section on
+     foundations can provide the necessary
+     information. Although the load bearing
+     structure is designed, this phase is not
+     yet finished. Finally the designer needs
+     to look into possible façades and roof
+     elements. Now a choice can be made
+     between the different concepts based
+     on a multi criteria analysis. The criteria
+     are based on the PoR and structural
+     assumptions.\\\n"

+     can be helpful. Make sure, also in
+     this preliminairy design, that stability
+     of your structure is ensured. It is a
+     good idea to search for alternative
+     possibilities for the foundation and
+     connecting structure to prevent
+     surprises in the final design stage. Also

+     attention is given to the foundation

+     from the main load bearing structure to
