I contacted Sutha to get plumbing design done for one of the project that I was working on (a triplex). The city of Toronto noticed me after 2 months of submission the requirement of the plumbing designs so I was in a rush to have it done as soon as possible. Sutha had been very accommodated and provided me with the drawings in a very short time and came up with an economic design. He is very pleasant to work with and I will surely ask for his helps for other types of mechanical designs as well.
