Affordable steel building;
Affordable house with intensive use of steel
Pascual Gavaldà, Marta; Octavio Bayón, Xavier
Nowadays Swedish construction is basically dominated by timber and concrete materials. Despite steel is not commonly used in Sweden, it does offer a lot of properties that make it very suitable for construction. For this reason, the goal of this project is to design an affordable building made out of steel in a city such as Lulea, where steel is an important resource. However, since steel is not generally used in Sweden, youth were considered the best users for the building. Thus, in order to construct a building as much functional, affordable and comfortable as possible, we decided to conduct a survey to know students’ necessities and preferences and, in addition to include innovative aspects to achieve this goal. Therefore, although modular construction is not widely used in Sweden either, was considered the best option for Swedish climate and the building layout, consisting of several rooms with the same characteristics and dimensions. Similarly, sandwich panels with great insulation properties at low price were selected for the façade. Milan Veljkovic, professor of the civil engineering department, was the supervisor of this project that has been carried out in collaboration with Monarken architects and LTU. The project started with a research of the new construction concepts and the study of the youths’ preferences. Hence the architects tailored the building based on the survey results and introduced the innovative concepts in the design, while the structure and the building parts were designed by LTU (Marta Pascual and Xavier Ocatvio). The project consists of different parts organised in the following order: 1. A comprehensive description of the country and its construction market, followed by a brief explanation about the affordable housing market, the current purchasing criteria and prices in Sweden. 2. An in‐depth explanation about the traditional housing concept consisting of a description of the main construction materials and construction types, as well as review of the building codes requirements and construction costs per region. 3. An introduction of all those innovative aspects used by the building and a description about why they were selected. 4. A risk evaluation analysis of the project where all the critical points related with the building are studied. 5. A detailed description of all the technical solutions such the structure, building parts, assembling, etc. Moreover, there is quantity survey followed by the bill of materials and the achieved quality analysis. 6. Finally, there is a complete economical evaluation of the project, where affordability is assessed. The aim of this project was to design an affordable building made out of steel. The main conclusion is that after an exhaustive economical assessment, we determined that the building is completely competitive in the current construction market. In addition, the building has an added value: it is possible to modify the building layout by replacing the modules. Thus, it can be adapted for other uses in a future. Finally, it is important to highlight that this project provides a good opportunity to introduce and promote all the innovative concepts of the building in the Swedish construction market.
