so a simple job turned into my biggest pain in the you know what today. I was asked to quote playground mulch installation for 43 yards of material. I quoted it to be "x". The guy said that it was quite high bid compared to another he had received. he then proceeded to tell me that he thought mine was high because it was quoting actaul playground certified material and that the other guy had not. He asked me to quote the installation for chip fines, which is a pretty similiar material. I said, if thats what you want i will, but doesn't it have to be certified? and he said not necessarily. So i beat the other company by like $20. Ok, so i installed 43 yards of material and got a call today saying that his boss looked at the material and was very upset on the material. There was about 30-40 piece of material (mostly bark and a couple sticks) that was in the material and that that was unacceptable. I said that he did not want certified material so i put a material that was very similiar and that there could be some bigger chunks, but not very many. I then proceeded to meet him at the property and he could not find one piece of material after digging through the material that would be considered "unacceptable". So there was about 30-40 pieces out and it was now clean. His boss wants me to take the mulch out and put the right stuff in at MY cost. After hearing that, does it sound like this should be my problem at all? They wanted to save money and get the cheaper material and now are blaming me. They also didn't give me any instructions other then put 43 yards of material in this area and level it to the top of the edging. Come to find out that playground material also has to be compacted somehow. I went into the job planning on installing the material as if i was spreading bark at some other property. No one told me to do anything differently and now this happens. i did it cheap enough already. I have told this story to so many people today so i might be missing a detail here or there, but everyone i have talked to said that it's not my problem. The problem i do have is i haven't been paid yet. Either way whats your guy's take?
