Henry,
Quechua is a touchy subject to Peruvians from the Mountain regions. The government wants to ban it, but given that 5 million still speak it, that's not going over very well.
There is a definite undercurrent of hostility among those who call it their native language when the subject comes up. I can't say as I blame them, what's going on down there sounds an awful lot like what happened to the native peoples of north America. As for learning the language, I consider myself good at a lot of things, but when it comes to languages, I am about retarded. I've spent 5 years of my life in South and central America, but still can't speak but a few dozen words of Spanish and or Portuguese.
As for the the infrastructure, Lima was not hit very hard, from what the people there tell me, they learned something from what happened in Mexico city in 85. However; it didn't take in canete, or other outlying areas. They were nearly wiped out. Most of those buildings were made of adobe brick, which shattered. They are still cleaning up the aftermath to this date.
As for the project, that would be the one, though I am representing the owner.
Regards,
Gerald
