View Full Version : Sprinkler Irrigation Quote needed

06-05-2001, 12:32 AM
Hello Irrigation people,
I had my last post disgarded, Ill rephrase this question diffrently.
I messed the other one up
I have to sub an Irrigation job out that will consist of possibly 40 heads in 6-7 zones I figure..
I just scaled things out and went by the average head being 17 feet apart covering an average 35feet, 5 heads per/zone..
I need a rough figure to use in this bid I need to fax 6/5/01 at 3pm
I have everything else priced out, consist of 325 varios plants, 18 trees, 5600sqft sod, top soil, mulch, 500lf aluminum edging..
Id apriciate any rough estimate one can shed light on for me
possibly maybe even what a ball park figure is per/head..
Pipe: Poly vinyl PVC scedual 40 pressure rated upstream from controls to downstream laterals, minimum pipe size one inch

Fittings: Type, size and style to match pipe

Ball Valves: Brass construction, non rising stem, inside screw with threaded ends

Valve Box and Cover: Aluminum or plastic sized for application intended with lockable covers

Y-Strainer with 200 mesh screen: Attach downstream from valve on all lines with drop emitters .

Backflow Preventer: Commercial, meeting all requirements of local authority having jurisdiction

Controller: Rainbird model ESP-8Si

Wire: Color coded 14 gauge or larger, single conductor solid copper with min 1/16 inch insulative covering of ICC-100 compound, UL approved for direct burial.

Sprinkler heads: Pop up type, sized to adequatly cover the area required

Flex tubing: 3/4 inch PVC with 1/4 inch PVC tubing runouts to emitters

Emitter: 4 gallon per hr for trees and 1 gallon per hr for shrubs

thanks a bunch ,, ill be checking the baord or you can email me
rough estimate is appreciated so i can send this off

Thom, there are a couple of things here that I don't think you took into account.

1) The irrigation forum is still fairly new and isn't getting nearly the viewings that, say, commercial lawncare is.

2) Your post was somewhat confusing to read. I had to go through it twice to figure out if you wanted a price on just the sprinkler job or on the trees, plants, etc. too.

3) If you're going to sub it out anyway, why not call the guy that you're going to sub it out to, get a quote from him, and tack about 15% markup on it for yourself?

Anyway, hope it went well for you.:cool:

I didnt know it was new,,
I was in a rush to try and get some idea, the irrigation contractors here on long island were all gone over that perticuliar weekend etc.. I had little time to finish that bid.
I came up with a guess however on it,,Im in Denver right now and just spoke to someone and they indicated I was too low :((
but high else where on something so maybe itll make up for it

Be sure and let us know how you come out, Thom, as well as why. Good luck!

I was told out in Denver from some fellow member that the Controller and Rainbird model ESP-8Si irrigation system should have been bidded at at least $300.00 per/head installed.
That was the number I was looking for a while back.
I was way off, too low

06-19-2001, 10:00 PM
300 per head ? LOL

He may have meant 300 per zone. The si series controller is not top of the line. I would go with the LX series instead, not that much more money and a much better controller. Depending on the time of year you can get between 300 and 600 pr zone, standard install with puller.

I agree that $300 per head is way off. Part of the problem with giving prices here is the competitive nature of this business. Some locales will support much higher prices than others.

06-19-2001, 11:37 PM
OK so possibly my figure wasnt that off then. Unless I scaled it wrong
I didnt have a good reliable contact at the time and assumed $125 / head,, Im not into the irrigation end.
The one fellow I knew well here in the industry just wouldnt bid on it unless the building was already up and completed and he knew the water pressure.
That surprized me some

06-20-2001, 07:12 PM
Thom that contractor was being smart. How can you bid an irrigation system w/o knowing the pressure/GPM output of the pump? These factors will affect the entire system.

06-20-2001, 08:15 PM
Avery is 100% correct. The irrigation contractor should not bid on the job untill you know:

(1) meter size

(2) size of the line into the house and past the meter, this is usually the limiting factor.

(3) length of the run, pressure loss through friction

(4) static, and if possible dynamic, pressure

The only way to bid a job without the above is, if you are on city water, bid on the minimum reqirements for main, meter and pressure reqired to meet code.

Example: For the purpose of this example the main line into the house is the limiting factor and the head total = 40gpm with 2gpm heads, we will assume 0 pressure loss from friction.

1) 3/4" main. Since the velocity cannot exceed 5 fps you could only put 4 heads/ zone, or 8gpm/zone, this would mean you need 5 zones.

2) 1 1/4" main. you would need only 2 zones.

It is very difficult to estimate a sprinkler without some kind of layout of the area. Too many variables. In my area $125 a head would fall in the ball park. Still would depend on soil conditions, utilities, Boring. You also had some specs for a drip system. Was there one to be installed? Also 17' distance? I am assuming you are talking about pop up sprays not rotors.

06-21-2001, 02:01 AM
NO!! the contactor wasnt being smart,, he just doesn't do commercial installations what so ever.
Yes he needs to know water pressure etc.. like you indicated...because thats what determines all your above

But you mean tell me there is no one bidding on new commercial jobs out there untill the project is completed and established???,,,thats impossible...!!!!!

These landscape installation jobs start with having to submitt a bid to the GC which includes the irrigation work.
You cant leave it blank or open, nor wait to the project is up and ready, you have to submitt a proposal meaning one has to come up with somekind of a close figure
Im the one who bidded on the entire project (which included irrigation) and was going to sub contract it out
I needed a freekin number to work with which I never got
Im the one who was taking the risk

06-21-2001, 09:51 AM
Im the one who was taking the risk

Exactly! That is why,in my opinion, the contractor was playing it smart.
If that contractor does not do commercial work why did you contact him for a quote? Not that it would matter much who you called. No contractor is going to pull a number out of the hat. He needs to know every detail about the system.

OK, Thank you all,
Bid was submitted 6/7/01 10 A.M.

06-21-2001, 11:16 AM
Just curious, but isn't there any minimum requirements and testing prior to becoming an irrigation contractor in New York State?

06-21-2001, 04:14 PM
I have submitted proposals for irrigation on new construction, prior to there being a building there. I test pressure at the nearest hydrant and get the other info from the general contractor. The GC must pull the permits, buy the meter and meet code so he should have all the info your IC needs.

Ok thank you Jim

06-22-2001, 08:29 PM
What did you bid?

06-22-2001, 11:51 PM
I allotted $8,500.00 within my bid for the irrigation installation.
Total bid was $ 61,102.00
Yes they where pop up sprinkler heads for the lawn areas and drip system emitters for trees, shrubs and plants. (18 trees, 325 plants, 8,000 sf sod)
I see the difficulty here now trying to explain a job layout such as this on a message board.
sorry about that.

A general bid in the Dallas Tx area since there are a million Irrigators here is for res. between $350.- $400. per zone or $20.00per head. Commercial is double plus if boreing is necessary.Matthew Li 8050
