Trouble finding building contractor for future project

[Mark Hu]

I have been trying to contact building contractors for a project 5 years + down the road. I've noticed that if I don't have the building drawings already done most do not want to talk or even send references.

Now is this because they are just too busy, or is it something worse? Is it difficult for contractors to get a good list of references, or do most of them not plan to be around in 5 years?
