In the dimensioning of a structural element, it is the structural engineer’s responsibilityto choose the type of concrete to be used by the given circumstances. However, theinfluence of external factors like the client or the contractor could affect the decision.But ultimately the decision comes down to the structural engineer. The approach ofstructural engineers in choosing concrete varies across individuals and companies, thereis no standardized method.The purpose of this study is to develop an effective and clear method for structuralengineers in selecting concrete and to discuss its potential impacts. This study is aqualitative case study with an initial survey. Data collection methods used in this studyinclude questionnaires, document analysis and interviews.In this study a flowchart was developed to make the process of selecting concrete clearand effective. The flowchart also includes climate-improved concrete as an optionproviding the structural engineers with the opportunity to propose both conventionalconcrete and climate-improved concrete using the same method.The study finds that the structural engineers use different methods in selecting concretewhich creates ambiguity regarding the correct choice. After applying the flowchart, thestructural engineers found it to be a clear method that was well visualized. Discussionsabout a standardized approach similar to the flowchart in selecting concrete wasdiscussed and its effects were seen as a good approach to increase insurance and clarityin selecting concrete. Additional discussions in the study regarding climate-improvedconcrete indicate a significant lack of knowledge among the structural engineers andthe need for improvement in the upcoming years.
