Hello I am new to the site and would welcome opinions of this particular situation. I have a potential customer who is interested in having a 225' Versa-Lok retaining wall built to replace an existing but rotting railroad tie wall. The height would vary from 3 to 4 feet high. His budget is somewhat tight and he has proposed that he would remove the ties himself and hire me to lay the first 2 courses of Versa-Lok. He would then "finish" the job himself. I would have him sign a waiver absolving me from liability but from a practical standpoint is there anything that I am not thinking of. It is a huge job and even simply starting it for him would bring in a decent amount of $. Fire away with your thoughts. Thanks.
