Full textThe purpose of this study is to determent what type of build it’s more economic profitable for the supplier of prefab element to use single-use sheets or form plywood as mold material. Tasked by UBAB a survey was made to see which of the mold materials’ the most profitable alternative in production of stairs. This was made through analyzing the processes time consumption, material cost and total cost. Working procedure is different between the mold materials and that is why the operations been charted through time studies for input and observations for a greater understanding of the processes. A material consumption has emerged through interviews that together with the information from the time studies been used to determent the total cost. The result shows that the total cost for the single-use sheet is greater than when using the traditional form plywood. Only the first cast turns out to be more profitable with the single-use sheet. For the single-use sheet to be a cost efficient alternative at multiple casts the material consumption must be lowered since the cost quickly becomes twice as expensive as form plywood. Even though the cost of single-use sheets is greater there are still benefits and possibilities for improvement. To develop standardized working procedures for the single-use sheet as well could make it more time efficient and by decreasing the material consumption could make the single-use sheet a more profitable alternative.

Full textThe construction industry is constantly striving for efficiency and optimization that can reduce a project’s construction cost and construction time. The construction of plant rooms built on roofs is perceived by both structural engineers and project managers as a step in the production that has a big construction cost and a long construction time. A plant room on a roof has other conditions compared to the rest of the building, which can slow down production and the construction time is therefore extended. One condition that separates the plant room from the building is that the plant room’s outer walls require an offset from the facade of the building. This leads to the plantroom’s outer walls not necessarily lining up with the underlying vertical structure. The loads that go down through the plant room’s outer walls create point loads on the plant room’s slab. The point loads could make the slab need strengthening, which is both costly and time-consuming. An investigation into the material of the structural frame's impact on the construction cost and construction time has been carried out. The aim of the investigation is to analyze which structural material is optimal with regards to cost, time and structural capacity. In the investigation three materials were analyzed by the conditions and requirements from a reference project. The chosen materials were a steel frame as well as light elements made from timber and concrete. The result shows that lightweight elements made from timber are the most economic option and concrete is the most time-efficient option. The conclusion is that the optimal structural material for the reference project is concrete.

Full textThe construction industry is currently responsible for about 21 percent of Sweden’s total annual emission of greenhouse gases. A major challenge is to be able to achieve the goals of the climate change act, which means that Sweden will not have any net emissions of greenhouse gases in the atmosphere in the coming decades. At the same time, the need for more housing increases in connection with an increased population. Concrete is the construction material that dominates today’s industrial construction of multi-storey buildings and in connection with the earlier Swedish law that prohibited wooden structures with more than two stories, wood construction in Sweden is not as developed to the same extent as concrete structures. In order to increase understanding and knowledge of CLT structures among operators in the construction industry, such as clients, the purpose is to compare a CLT structure and a prefabricated concrete frame based on differences in environmental impact, material cost and construction time. With documents from a reference project with CLT structure obtained by the company Bjerking, an investigation of the construction’s material consumption has been accomplished, in order to be replaced with a prefabricated concrete frame. The comparative study has been completed using the material consumption for each frame. The results shows that the CLT structure has less environmental impact and total material cost compared to the prefabricated concrete frame, however, not all materials in the CLT structure are included in the study. The excluded materials are reportedly costly, which in the end means that the CLT structure can become the more expensive alternative. The construction time, which in this case is the time for the frame assembly, was estimated to be about one working week per storey for both frames, but less workers is required for the CLT structure. The conclusion is that the CLT structure is the most environmentally-friendly frame material for building the reference project in Kajstaden because it contributes least to the environmental impact. The prefabricated concrete frame is more advantageous if a lower material cost is the priority. If a shorter construction time with less workers is desired, the CLT structure is more favorable. In the future, the most important parameter in the choice of frame material should be the one with least environmental impact for the construction industry to become more sustainable.

Full textThe Swedish agriculture is developing towards fewer and larger farms. The growing business for the farmers results in an increased number of animals in livestock. This provides a greater need for agricultural buildings with open spaces and long spans. Länsstyrelsen has noted large variations in total construction costs for agricultural buildings in the country. Along with Länsstyrelsen Gävleborg developed an idea to explore how material costs are affected by various spans and different frame systems. The objective is that the study will result in a decision-making basis for new construction and reconstruction of agricultural buildings. Previous research and theories were examined and a number of site visits were made to increase knowledge in the field and determine which spans and frame system to be investigated. Parametric studies of four different scenarios of the agricultural buildings were made. Two cases in the study were constructed of glulam and two of steel. The parametric study is to report relationship between agricultural building spans and costs as well as which building system that is most economically advantageous. The cost of the survey includes only material costs. The result shows that the cost increases linearly with the increasing span. The material costs of the four tested scenarios are relatively equal, but the tapered steel frame has the lowest material cost for all tested spans.
