    I am in the process of preparing a bid for an irrigation system for a restaurant. There is one turf area and a flower bed near the main street, but the main areas needed to be irrigated are near the building itself. The restaurant sits in the middle of an older asphalt parking lot. Going underneath the asphalt without disturbance (i.e. torpedo) is not an option, just too much length of travel. I am not sure where the meter is but regardless of this we will need to go through the asphalt somewhere. Considering the shape the asphalt is in it will be no big deal to cut it up.
    What is the best way of doing this? Or is this one of those ones where it would be best just to walk away? They are family friends of ours and plus it would be great advertisement for our company to work there. My main concern is getting the asphalt up plus not knowing what is underneath said asphalt. Any advice would be appreciated. At this point i am guessing we would have to score and pull up the asphalt, then trench, then put it all back together.
    Thanks!

    BTW, the sprinkler system itself will be a breeze, prob 1 zone for turf and one for the beds. The turf area is very small. Think there are 3 beds that need to be irrigated. Thinking drip on them. I think there will be good pressure (major street with tons of businesses and neighborhoods feeding from it so they should have hefty pressure at the street) so I could get away with one zone but think i really need to separate the turf from the other plants because of different watering requirements. That would be if I ran spray heads on all materials, I definitively would not run drip and spray heads on the same zone!!!

    You Could directional drill it or use a k saw and cut the asphalt then dig. Either way call for mark out and hire a private mark out company to mark any consumer owned stuff like light posts etc.

    You might want to check to see if irrigation can be attached to the resturant water line. I am pretty sure in our area you can't....at least all of our have seperate meter and back check. I see guys cutting that asphault all the time for lighting....usually hand held saw if not very far. They fill it back with concrete.

    I could put it on the restaurant water but the majority of the stuff that needs watering is out in the parking lot itself. Either way I am going to have to go through asphalt for at least 50-100'.
    What about using a pipe puller? Then i would not need a very wide cut in the asphalt (if any?)
    When you mean K saw you mean kwik cut saw right?

    K saw = gas powered saw with diamond blade. I have pulled through asphalt with my machine but it was across a residential driveway I don't think it would work in a parking lot.

    I figured that was what it was but I was just checking.
    I'll get a pic of the asphalt this up coming week, its not every good and I'm beginning to wonder if I could get away with pulling through it since its so crumbled. Only thing is that the base is prob red clay and would be hard to pull through.

    Glad to know that, It's too bad they don't teach the real world stuff in Irrigation school. You have the right attitude however and should go far. I hired myself and a supervisor of mine out to a a small company right after we got our licenses. We had four people doing an install and all four had licenses numbering from the 2000 to low 3000 numbers. I'd say it was the most qualified installers in Texas, but two of us were new and didn't know Jack yet. I asked questions and learned a great deal from that one job. Some of it was what not to do. I still ask questions and try to not make the same mistake twice. Still going strong almost thirty years later.
