Thank you plantladylin - for what it's worth, our contractor was actually pretty fantastic in most regards. I may be being a little too harsh on them. I went with the most expensive contractor bid because his itemized list specifically reflected a wash out basin (so they weren't washing tools and disposing of debris on my lawn). But, big burly concrete construction guys aren't exactly dainty. I even went to the extent of expanding my own Spanish so I could effectively say "no Pisa esta flores. Pertencian a mia abuela morta" No stepping on the plants, they belonged to my dead grandmother!
