Conclusion

Three major existing solutions are available. Due to it's specific nature (fragmented, low budget, many relationships), the building and construction industry isn't using any of these solutions. So there is no industry-wide standard for the building and construction industry and none of the three existing solutions comes close to being that industry-wide standard.

The first conclusion is that the building and construction industry lags behind when compared with other industries. The second conclusion is that a simple, cheap electronic solution is needed. The third is that a mapping of languages and concepts onto each other is needed.
