I'm not sure if this is the correct forum, so if not please move it Jeff.

I have a bunch of questions about installing a large pond liner. We are developing a partnership with the irrigation company that we sub our work to. We have been working them for many years and they have provided us with excellent service, we have given them referrals and they have given us referrals. They are getting into the pond business in a bigger way but they do not have the equipment to dig, grade, haul pond liners, install, etc.

Sooo, I could use some advice. The first project that they want us to price the install on is a small detention pond. Approximately 150' X 270' and 10' deep. Yeah, it's a nice small one to start out with, but I figure if we can handle this, anything else will be a piece of cake. We will probably have to do some of the finish grading, but most of it will be handled by the excavator, so that isn't too much of a problem, the problems are:
1) How thick of a liner am I going to need? Does it need to be double lined?
2) Am I going to need any sort of underlayment? It is all sand in this area, hence the need for a liner.
3) Any suppliers that you work with on something this large?
4) Approximate weight? In other words, how in the world do you move something like this around?
5) Any approximate installation production rates? (I know, it's different for every company) but I still need someplace to start.
6) Any other pitfalls or craters that I am not thinking of?

The irrigation company is going to handle the pumps and electrical for the fountain and stream from the upper pond, there is going to be a recirculating pump from the lower pond to the upper pond. I figure I'd try to get help on the big pond and the smaller upper pond and stream should be a piece of cake.

Thanks in advance for any advice.
