3D BIM from 2D-drawings for calculation

I work for a construction company in Sweden. We want to start using models more in our calculations by turning 2D drawings into a model that we can use for quantity takeoffs in the early stages of projects. We are looking for a partner that can learn how we want these kinds of projects for us and be able to do them on demand with relative brief advance. As a pilot project, we want to see what kind of quality we can get from doing the model abroad. One challenge is that the drawings and descriptions are in Swedish. We are looking for a basic model where we can use volumes, areas, length, and count of different objects for calculation. Objects with different kinds of characteristics need to be set apart with different IDs. For example different kinds of walls, doors, ceilings etc. In the long run, we want to have these objects classified to a Swedish standard but for starters just be able to set them apart will be fine. We are looking for a model in .ifc containing - slabs - columns - beams - walls - roofs - floors - ceilings - doors - windows - spaces Because its a pilot project i dont have all the specifics now of the end product. I require that we have a good communication during this project and solve problems on the way. Regards Arvid
