Those dump trailers are handy CM, I find they work good as a mobile stone box if you're working in a parking lot or road with a mini ex and can't reach over the gate of a tandem, throw 4 or 5 ton of rock in the trailer and scoop it out as you need it.

Love my dump trailer. I can't imagine not having one. Don't buy a big tex though. Big piece of garbage. Gets the job done though.

That's right movindirt, it could be very handy for the small jobs that come up although I would probably use it just as much for personal work. I need about a yard of pea gravel in my fire pit and I've got some junk I need to haul off..:D

I haven't been that impressed with the Big Tex trailers I've seen either Aliate. Although if one came up cheap enough (I'm an auction bottom feeder) I'd buy it.:D

Pictures from this week at the auto parts store.

The front parking spaces will be pervious concrete with a rock storage chamber underneath with 6" per PVC to drain into an existing inlet.

Excavating the stone storage area. To the right in the pic is where the old curb was we removed, the new curb will go back in the same place.

Using the 279 to clip the bottom after the excavator dug it out.

IMG_2109.jpg

Filter fabric down, placing some #2 stone that makes up the water storage area underneath the pervious concrete.

IMG_2111.jpg

The design called for 2 runs of 6" perf PVC highway under drain. Pipe installed and covering with rock. A little track loader love finding it's way into the picture.

IMG_2115.jpg

Connection to the existing inlet. At the time this pic was taken we were waiting on 2 6" T's to connect the two runs together.

IMG_2116.jpg

Closer look at the connection to the existing inlet. One of the crew is cleaning out the existing inlet. We had to lower the grate about 6" to meet the new plans. Luckily there were 3 runs of brick on top of the lid so we knocked that off and re-set the grate.

Once we installed the T's and tied the two 6" lines together, we used some recycled DGB from the old parking to to bed the pipe and bring the bottom up to grade.

On a side note the Husky K760 has been a very good saw. In three years all we've replaced is the pull start assembly which was $60 at the local shop, not bad for 3 years of abuse errr I mean use.:D

Dumping a 25 ton load of #2's.

IMG_2118.jpg

The dump for the excess dirt was close to the quarry so it was take a load of dirt and get a load of rock type of operation.

IMG_2120.jpg

279 finishing out the rock. The two 6" pipes behind the skid are clean-outs and the one at the far end is an inspection port. The location of the clean outs were per plan which didn't make sense to me being 1/2 the way of the run of pipe, I would've designed them to be at the end of the uphill run next to the inspection port. The design did not call for a two-way clean out either.:beatsme

IMG_2122.jpg

Overview of the front parking lot. The 321 is cutting to sub-grade in front of one of two "retaining curbs" - IE short retaining walls that also serve the purpose of a curb.

There is around 1500 loose yards of export on this job including spoils from footings and underground utilities which we're getting paid to haul off.

IMG_2123.jpg

Passed two Abrams tanks on the interstate, they were probably heading to the Anniston Army Depot for a re-build.

CM some great looking pictures, of might fine looking work that you are doing. I sure enjoy seeing what you are working on, and the insight of hearing how you do the jobs, and how you would do it if it was left up to you. Thanks for taking time to share!

Thank you for the kind comments dirty4fun. I want to share my limited knowledge of what we do in the vast industry of heavy equipment on HEF, like our very knowledgable mechanic members share their knowledge of how to repair a machine. There is not another venue on the net that has the down in the trenches knowledge of the heavy equipment world like HEF.

One of my favorite sayings is - "We get paid to install it, not design it".:cool:

That is an interesting underground retention system. We have never done one with just rock like that, they always have the upside down U style or we have used big pipe like 42". Interesting none the less.

That is a good bit of sitework for a small store like that. I wonder why I always see the Cat ctl instead of the Bobcat in the pics:D

I agree with Dirty, thanks for posting.

LC this is the first one I've put in but I've seen it spec'd before. Rather simple on design and installation. The system is supposed to let light water flow percolate into the ground with the perf PVC acting as drains for heavy flow. In reality the heavy clay/chert it's in won't let much if any water percolate, so it will act more as a detention system.

I've never seen pervious concrete so that should be interesting.

Bobcat is at the shop with a hydraulic leak somewhere in it's bowels, no timeline to dig into that engineering nightmare at the moment..:rolleyes:

CM have you thought about getting an offset disk you could pull with the d5 for mixing a drying? Seems like you do undercut and flip pretty often. This video might interesting for you.

https://www.youtube.com/watch?v=8rbNznCBKI8

I have heavy, actually it's one of the items I regularly check for coming up for auction. It would've been overkill on this small project but the D5 is cheaper to run considering fuel and UC than the 953.

A friend of mine in concrete business posted that video on FB a while back. Pervious concrete is very interesting and I think we'll start to see more of it as storm water regs only get tighter, which is fine by me.;)

They have done a few parking lots in my area with pervious concrete here recently, they were in tight areas that did not allow for a open retention basin, so they took the calculated rainfall they needed to store and put it underground. From what I remember they used 1" clean rock for backfill as it had the most water storage capacity (something like 1/3 of every cu. yd. of rock was open space) The ground in this area is really dense clay, IIRC they oversized it by quite a bit just so that it had room to store plenty since it will take a while for it to drain out. Its some pretty cool stuff, I would think it will hold up fine in your climate CM, not sure how it will do here where we get a lot of snowfall and freeze/thaw cycles... seems like that pervious concrete might start to break down after a while.

Good point movindirt about how the pervious would hold up in different climates. There will be a sign erected in front of these parking spaces noting to not pressure wash or use sand abrasives during snow events and to use caution during plowing snow. Since we only get a snow event down here every few years and it's gone in a day or so I don't think it'll be an issue.:tong

Now the real question is how will all the oil and other fluids from the leaking cars affect the pervious? I would suspect not much and the gravel may filter some of the run off.:beatsme

my ? is what going to happen after a couple of years of landscapers blowing grass clipping's on in and leaves ,mulch ,general dirt and grime then it's all stopped up and won't drain any more. Then who pays to fix it and how.:beatsme

That's a good question Clint as this is the first I've seen of it my area. I'm along your thought lines, over time general dirt and fines would seem to clog up the "pores" but since I've never been around it we'll find out.

Since the concrete itself is not in my contract all I need is for the water to flow once it goes through the concrete.:D

We have never did anything with pervious concrete but have used pervious asphalt on a path that went over the roots of a grand oak. We had to use crushed concrete under it as well so the water could get to the roots.

LC I would think pervious concrete and asphalt would work well in your area with the sandy soils.

It's the opposite here with our heavy clay soils, pavements are designed to keep the water out of the sub-base as it will lead to failure. This particular parking lot has 2' of #2 stone on it so I doubt with light loading and that much stone stability will be a problem.

Went to a demo day at our local dealer for a fully integrated GPS D6N. This is a Cat corp. tour to show the machine. The lead engineer for this model D6N was there to answer questions.

IMG_2125.jpg

Sitech was there which is the technology company partnering with Cat for the electronics. They built a simple model with a pond and a short section of road. I'm currently in the bottom of the pond.

IMG_2126.jpg

It was a beautiful but very hot day. In the bottom of the proposed pond making a cut. I backed up to the edge of the pond put it in F lowered the blade and the machine took over the cut. I took my hand off the blade joystick and the tractor made the cut until it loaded the blade and then automatically lifted the blade and carried the material to the end of the cut like one would do in a slot dozing situation.

IMG_2128.jpg

IMG_2130.jpg

This was the first time I have been on an integrated GPS machine. This D6N doesn't have masts for the receivers they're built into the machine with all the other sensors. This tractor also has the capability to run GPS masts as well as laser masts. The GPS receivers can be seen mounted on top of the cab in front of the A/C unit.

I was very impressed with the machine but it's already one of my favorite dozers to run. The new models are more powerful than the '06 I had. The GPS and automation was impressive, there would be a small learning curve to get used to it but I see it's potential. However the tractor is pushing $320K as it sits so there's not one in the near future.:cool2

However this dozer would be ideal for large grading jobs such as residential subdivisions. It would cut the time to pad lots and grade roads to 1/3 of what it takes to do it with a laser and grade checker. I could see one machine such as this dedicated to fine grading with the rough cut/fill being done in conventional ways.

What I did take away was this technology is it will not replace an experienced operator. Rather it's a powerful tool in the hands of an experienced operator to be more efficient and eliminate a grade checker on the final pass.

Finishing up the auto parts store. The local fire district wanted the sign so we saved until the end to take it down.

IMG_2133.jpg

The structure of the sign was a 10" thin walled steel pipe, encased in the footing. Cut the pipe except for a 2" tab on the left side of the pipe in the pic.


IMG_2134.jpg

Got it on the ground in one piece.

IMG_2139.jpg

The steak house is just about finished up. It's going to be a nice building. The wife and I should get two tickets to the soft opening.:D

I like 6ns myself. I have never been on a machine with GPS and I think I would have a hard time adjusting. Did the machine load the blade evenly and smooth or did it jam the blade down until it started to spin tracks then let up?

Looks like the masons are rolling on the auto parts store and you will be back to finish up in no time! The Outback turned out nice and you should get a nice steak and lobster dinner on the house:D
