Please excuse the misunderstanding. I was not trying to be nice. I was only pointing out that there are morons everywhere on earth. This is not unique to the Phils. In the USA I once hired a roofing contractor that had been in business a long time and had good references. They subbed out the roof removal and installation of the underlayment to a subcontractor. The subcontractors workers were clueless. The underlayment is a water resistant layer below the roofing tiles. It comes in rolls and is supposed to be laid out from the lower portion of the roof to the top just like tiles with each upper layer overlapping the lower layer. This way the water running down the roof will go over the seam onto the lower layer. These morons in the USA did it in reverse from top to bottom. This way the water ran under the lower layer and into the house. The general contractor did not notice the issue when installing the roofing tiles. My point is that there is poor quality workmanship everywhere. It is not exclusive to the Phils. Here we do not have the long term relationships where we have sorted out the bad quality from the good. We cannot trust the people sent by local businesses. We meet people randomly and do not have the time to sort out the bad quality from the good. Random local workers are OK for the work that we can see and can be reworked. Framing, masonry, etc. Plumbing and electrical is a bit more sophisticated and we need to be more involved in its design and installation. You have a team that you have been working with. Next time have the local vendor produce a sketch and a bill of materials that you will buy and have your team install under your direction. This way you will have better control over the quality. In the end this is what happened. The welder working for you built the shelf. We have no idea what experience they have or what Polaris is paying them. Maybe they have spent their lives working in a coconut plantation and cutting sugarcane. Nah. I am not going to tell you to go to church. You will not get your plumbing work done there. What I am saying is that in order to ensure the job is done correctly you have to lay out and direct the work yourself. As the saying goes: "If you want it done correctly then you have to do it yourself". The advantage here is that we can pull together low cost teams that do the physical work at our direction.
