Just trying to review my pricing. Some days I think I am too high and others I feel like am too low. But then things always look to come out right. I am bidding a 185' drainage job that I don't want to lose on. Basically renting a mini excavator and taking a trench down the side of the driveway, putting in 2 or 3 drain boxes and then running the pipe to the street. just looking for a guesstimate for what I should be around.
Any help would be great!

I would charge approx $12 - $15/ft + rental cost

I am paying $9.80 for installed 4" pipe, sod lifted and replaced. I am paying $3.00 a foot for 2" pipe installed.

Ok the area is right along side a gravel driveway. I would say a little sandy and its all flat or already sloped toward the street. installing 4" drain pipe and 2 12" drain boxes. I was figuring some were in the range of $8 - $10 a ft. Pluss the rental of the excavator. Have hand dug a drain this long before but it was not fun and was also just across a back yard.

You should be in the range of $14/linear foot for 4" hard PVC.

I'd add $75.00 per 9x9" catch basin, and $100.00 per 12x12" catch basin.

Also, cutting the curb, boring in to city main, tapping in to downspouts, etc. is extra.

BTW - I would NEVER rent a mini ex to dig a couple hundred feet for 4" pipe...

That's just me, though...

Neglected to mention, though, that the soil down here in Southern LA is soft..

Might be a bit different in VA (i.e. hard-packed), thus warranting the mini-ex rental..

are you wanting a true french drain with rock or just put 4inch soild in and a couple of catch buckets?

12 - 14 per ft. of pipe, 75 per 9" basin, 100 per 12", plus rental.

Have you considered a riding trencher set up to cut 6" - 8" instead of mini-ex?

This is just 4" black plastic drain pipe. Would dump into the ditch that runs in front of the house. Along the are that has the issue I would do a french drain. That is about 40 -50 ft. The rest would just be solid pipe. The catch basins are for the spot that gets the worst water build up. I guess I should have explained this better when I first started the thread.

Had not thought of using a 6 - 8" trencher. That would definatly make it easyer to backfill. Have not bought a trencher yet just b/c I have access to one for when I need it and most of the irrigation work I have had lately has been addons to back lawns that are also geting sod so the soild is easy to dig once its been loosend up by the tilling or just repairs on exsisting systems.

I'm an open trench guy myself.

You can rent a trencher same way you'd rent a mini-ex.

Personally, I never run black corrugated underground.

I always stick to hard PVC.

More expensive, but will last muuuuuuch longer..

You say it will drain to the street? Is that even legal there? Around here thats a big no.

I'd say over half the drainage jobs I've seen are improperly or poorly done. My friend that I refer out gets a structural engineer involved in many cases and may be the only drainage guy I see using a surveyors level to determine grade and slope. I'm sure there are others, I just don't see many. ADS unless for french drain purposes makes for many a poorly done drain since it comes rolled up and most contractors don't take the time to get it straight in the ditch.

Also the dumbest thing I see is mixing a french or gravel drain with the downspouts. One drain pipe serving both purposes.:hammerhead:
