Abstract [en]

The goal of this thesis was to identify the development process for a configurable product in the construction industry. This has been done by testing a modified development process from the engineering industry on a case study where the main beam of an end frame bridge was configured. By developing a configurable main beam the following six steps could be tested on the case study, Breakdown of construction, Choice of geometry, Choice of technical solutions, Validation of selected geometry and technical solutions, Production of general calculations and Validation of calculations. Four additional steps could be identified for the whole development process, two prior to the tested process; Choice of product type and Data collection, and two after; Configuring and Updating. The steps in the development process were modified at various points in time by a work group comprised of people specialized in bridge design, module development and bridge production.The background as to why the thesis has become relevant to investigate is that the construction industry is often described as an industry with low production development and insufficient quality (Byggkommisionen, 2002) (Statskontoret, 2009). The main reason for this is the unique solutions developed for each project (Simonsson, 2011). Calculations and construction documents are either fully or in part produced manually for each project, which leads to only a few details can be reused from previous projects. These constructions can be seen as products with integral product structure with no connections to its product family, and therefore knowledge transfer and reuse is hard to achieve. The technical consulting company Tyréns has made a pilot study on end frame bridges. The study indicated that the time for design and review can be reduced if the design is based on the idea of product configuration and platforms as opposed to the traditional design (Jensen et al, 2013).The thesis was performed at Tyréns where a work group comprised of specialized people work with developing a configurable end frame bridge. The work with developing a configurable main beam was done as a part of that project. The information was gathered at group discussions, meetings and literature study.In order to get configurable products used in the construction industry it's important to choose products requested by the market. It should be possible to produce a large variety of products by changing a few parameters in order to fulfill the customer's needs and it should be possible to configure the product in a cost efficient way. The main challenge in developing configurable products within the construction industry is to fulfill all standards and at the same time keep the general calculations from getting too complicated.
