Dos Rios was hired to build a large concrete retaining wall, at the bottom of a hill in my backyard It was a sizeable project, involving an engineer, an architect as well as city permits. In hindsight, a project that i don't think he was experienced enough for. He was on site for 11 weeks, before i fired him and hired another contractor to finish the project. The top of the wall is not level, one side is bowed out, and one part of it is not actually the length it's suppose to be- it's short by about 6". In addition to that, the beveled edge, the only real "decorative" aspect to the wall is uneven and looks unsightly. He did not shore up the hill, until after it collapsed, and only did so, at my added expense. He did not provide his staff with a port-a-potty. despite them being on site for 11 weeks! I would not recommend Dos Rios. I dealt with about 6 professional contractors last year during this renovation and Adrian was by far the most challenging to work with, communicate with and was simply unable to meet any of the deadlines.
