I did a fairly large furniture store that also sold flooring and we installed many various rooms with their brand of birch engineered floating planks. This was a European concept store so the planks weren't glued together, neither was there any kind of this new fangled "click" system. You just tapped them tight together. The gimmick was when you decided to move you could then easily disassemble the product and take it with you to your next home.
Go figure.
Anyway, a side note on that project the wood floor rooms were pretty large, open areas out in the middle of the store---like 1500-2000 square feet per. The owner's rep comes along after we're about half done to check things out. He goes right to one of the white washed birch floors and claims that this one is supposed to be some other kind of wood, with a natural finish. Maybe it was also birch but the stain was WAY wrong according to his set of plans. I had my set of drawings right by my side and showed him I had it right. Somewhere along the line they failed to swap out the colors on two areas and forward the new plans to our office. Where they wanted darker and one they wanted white wash we had them reversed. So we got paid to sand down, restain and refinish both areas. I don't do that kind of work so we subbed it out. I recall being very impressed Monday morning when I came in and they had fixed the error without having to tear anything out.
