I have an early 70s house in the US and looking to remodel. I spoke to a structural engineer about moving interior walls and he said he needs the following from me to give me a proposal on cost to do the analysis: copies of the plans, as-built cad drawings, and drawings of the new design.
These requests seem logical so I am trying to figure out the best way to go about this. I have an incomplete set of plans from when the house was built and he has looked at those already. They are discolored and faded as you can see here: https://imgur.com/a/NIYMmw8. He also advised it might be much cheaper for him to re-create the drawings in cad vs an architect but best case would be for me to provide it.
My questions are:
-
Is there a service/app that scan scan the old plans and create cad drawings or is this going to have to be 100% manual?
-
Is there a service/app to get as-built drawings by scanning the current house interior?
-
It’s basically 2 rooms in the house so I wouldn’t need to do the whole set of plans, maybe 5-6 pages total?
Thanks in advance for any advice. This is my first time doing a major remodel like this and I want to do it right.
