Potentiella armeringsfel inom byggproduktionen : En generell studie

Sammanfattning: Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves. In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition. Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy. It happens that problems and mistakes occur, however they are usually not extensive, but in some cases the errors can lead to severe consequences such as structural collapse. This thesis has been written with the purpose to discern and enlighten the most common errors during the reinforcement process, especially orientated towards reinforcing drawings. Literature studies with elucidation on old known problems and errors have been investigated and thereafter compared with present issues. Data collection was conducted through interviews and a survey distribution to personnel with relevant experience. The results of the interviews and surveys revealed that several significant errors have arisen, errors that previously weren’t taken into consideration. The computerized society has led to the construction process, in some cases, becomes faster than the planning phases. Some parts in the construction process no longer have the time to do extensive and thorough planning as they used to be able to. To prevent these problems, extensive quality checks, but also competence- and execution training for involved personnel is needed. By knowing the most common errors during reinforcement work more focus can be given to these parts in order to increase the probabilities of the work being executed correctly.
