OK, I have this irrigation system that needs service severely... The whole thing is a wreck... and that's putting it lightly. At this point, primarily... this system NEEDS a full reset... It over-watering and under-watering and running multiple times a day during the DAY. Everything just needs wiping clean and I need to start over from scratch re-programming. This is a 4 program 21 zone system. Lord knows how many heads... some mist... some drip too. Right now, it has 3 programs in it and the zones are all jumbled up across that. Nothing is right. But I am not so much worried about all that. What's getting to me is that the contractor who installed it (lowest bidder) did not supply the customer with a programming chart of any kind... No programming info, no wiring info, no master valve or pump info, no schematics or spec sheets. This was on purpose I am sure. Anyways, this means that I will have to test the electrical and I will have to go in manually and chart everything... extracting all the info prior to starting with a clean slate. I'm going to have to go through one step at a time and figure out every last detail of the system. Then re-program. I can do this and draft a whole new program to get it back to a reasonable state... then later do any repairs, head adjustments and program adjustments to tweak it on into perfection.... on a separate bill of course. So now you have a mental picture of what it is I'm dealing with... And you have an idea of what the first phase achievement goal is... So how would you go about calculating what you would charge for this? I've calculated it a couple of different ways and it sounds expensive to me.
