Hey, I've been working on a bid for a customer that I would like to get to him this weekend. The job is building a 2 tiered(sp?) wall, I was going to be using some type of allen block, but now he decided he wants some BIG rocks. I've never used anything as big as he wants, he compares it to another house close by, I'll try to get some pics of it up. Any way, the rocks are very natural looking, but must be made as they all stack so well. They are probably 30" long and about 12" tall. They job would be to tear out 2 existing walls made of RR ties, and replace with this rock. The walls are about 50' x 3-4', and 40'x3', I think I have a place to take all the old ties, but I don't really know how to price removal, as I've never removed more than 5-10 at a time. If I end up with this job it may be the one that drives me to buying a skid steer, as I have needed it alot and would pretty much require it here. Anyway back to the wall, can someone who has done one similar give me some tips on base prep and any other suggestions?? I love this type of work and always end up with onlookers and new clients when I am doing one, but this is new for me, give me some advice. Actually, if this thread works, a picture of the style wall can be seen behind my bike HERE This looks like the same style, but the rocks are about half size of these. Thanks for any help.
