Modeller för att underlätta upphandling av entreprenör: en undersökning och analys av vägentreprenörernas behov och krav / Models to facilitate contractor procurements: An investigation and analysis of the needs and requirements of road contractors

Introduction – The objective of the report was to gain an understanding of how a roadconstruction model should look like and what information it should contain in order tobe suitable for the contractor´s production. Also, to be able to take this further towardsstandardizing the working process. Method – The report has been conducted as a survey, where the main source ofinformation has been semi-structured interviews with candidates that the group hasdeemed to have high competence in BIM and road construction. Results – The study revealed that there are shortcomings in understanding betweendifferent actors and that the purpose of the BIM model itself can be perceiveddifferently. Contractors are mostly interested in getting 3D polylines that are elevatedin the correct coordinate system, and if the model is not complete is not a problem ifthey get external documentation on what is inadequate in the model. There is a need forstandardization throughout the construction process, which should be followed upsuccessively to maintain the quality of the design basis. Analysis – There is no common knowledge about IFC, meaning that most intervieweesdid not mention much about IFC but talked a lot about the need of good coding that isrelated to it. There are questions about responsibility for a road model, who isresponsible for the model, and how the designer can easily waive their responsibilitywith the help of documentation. Discussion – The group believes that they have received useful answers from theinterviews, which has been analyzed to form an understanding of what can be improvedregarding the road construction process. Competence in understanding BIM need to beimproved to achieve standardization, and the purpose of the BIM model need to be clearto improve the design basis results for production. To achieve even higher reliabilityand understanding, more interviews from the contractor side could have been needed,but lack of correspondence prevented this.
