If I had to drive around 50 miles or more getting everything & going to the job, gas for the welder & truck, buy concrete, rent a mixer (or mix it all in a wheelbarrow, no thanks), rent a bobcat W/auger (or rent something else), buy the pipe, cut, cope & weld it in pos in 110 degrees, hell yes! If there's Caliche under that dirt, you'll be hiring someone to cut thru it, or be jackhammering it all day. That ground is probably going to be hard, no doubt, but I always bid everything out at worst case scenario. I've been there too many times with the logistics of a job costing you more that the job was even worth. I have never put a pipe style fence up & would not want to rape someone on it, but I get paid for what I know as well as what I do. Pricing & hourly rate is different there too, I understand.
I charge around $100 a linear foot for wrought ornamental iron here. That will usually include materials, painting & installation, but that's a little different than this. I can understand the simplicity on a pipe fence, but unless I round it all out to getting $50-55 per hour plus my drive time, I'll just let it go on by. Too many hacks around here working for nothing, I can't afford to be one of them. Not with what I have invested in all my equipment & overhead. I don't have a 9-5 to fall back on. That changes the dynamic of the situation drastically. I've lost my can on a few jobs I under bid & then ran into horrendous problems. My post about that scrap job was one perfect example. It wasn't even worth all the running & headaches for what little I got paid. Ended up paying them, darn near, by the time I was done. I , again understand this a different deal & I have never done it. I just wouldn't want to get big shaft on it if I underbid it. At least from my perspective. :-) S.W.
