Many different elements related with technique play a key role in the art of building: materials must be chosen carefully, the most efficient sollutions must be attained, and the most suitable construction systems must be used. The concept of construction is the cornerstone of the exhibition “STRUCTURAL POINT. Structures Construction Mock-Ups”, with a special emphasis on building structures. This exhibition is made up of 50 detailed mock-ups that show every nook, detail and constructive element of the buildings, where different types of materials (reinforced concrete, wood and metal) have been used. The works have been made by the students of the Degree in Technical Architecture of the Polytechnic University College, as part of the subject “Structures Construction I and II”.
