Hey Guys I am pricing out my first walkway for a customer. This walkway will be approximately 40 feet long and I will be using landscape timbers to create essentially a long staircase up a relatively gentle grade change. I plan on using Techo Bloc to fill in the landscape timber boxes that will become the "steps" of this walkway. I have never priced a job like this before so I was wondering what everyone thinks is reasonable and what aspects need to be brought into consideration when doing this. Any imput would be greatly appreciated!
