There's a company in the Boston area that does about 90% of all concrete saw cutting. They are called Pro-Cut and I have seen there trucks around since well before the beginning of the Big Dig.

I was just on a job in downtown Boston with JF White and ProCut was using a track guided diamond saw to precut an area of wall leading into a subway station that was going to be hammered out by a Brock the next day.

The ProCut crew was one man with his Isuzu NPR 1/4 box and flatbed truck mounted to the gills with scaffolding, ladders, hose and compressor doing what he did best.

I was able to observe Speedy Sawcutting in West Palm. Fact!!!!! Sub out the concrete sawing. Those guys worked like mules and for peanuts. The saw blades were very expensive and they ate up about 6 of them. People that do sawcutting are very talented, strong and they work on slim margins. Not a job for the weak also. I found sawcutting to have less impact on the neighborhood too.

I hear ya there. I could never cut straight with a ring saw, scoring or not.

It's possible to cut with high accuracy with the ring saw, before cutting with the ring saw you should cut with a "normal cutter" 6" deep, and after that cut with the ring saw. when cutting with the ring saw you shouldn't apply any pressure on the disc, otherwise the drive rollers will slip and the cut can start to drift away. by cutting in many rows, only 1-2" deep/row, it will cut straighter and be a lot more efficient.
and like i said earlyer, use only HIGH quality disks on it, if cutting concrete!! for concrete we only use the Husqvarna soft disk, it's really good in even quite heavy reinforcement.

but in any case, i rather use the pentruder wall saw, it's so nice to stand with a remonte controll instead of cutting by hand :D

yea i remember some door openings i had to cut with that ring saw through 10" of reinforced concrete, the saw bucking when it hit rebar and tossing me off some baker staging after it slammed me in the chest. What a great tool.

i think its a partner 700 series? not sure though.

Good luck this summer hope everyone does well.

I've been cutting concrete for 22yrs. maybe in another 20 I'll have it figured out. :confused:

then it's not because of the experience!

what model ring saw do you have? the old model was worth it's price in scrap metal, but the new models are neat! you can cut with the ring until there is no longer diamonds on it, without any major adjustments. and the adjustments are really easy to do!

we have had some "professionals" working for us that never did learn that you can't load and push the ring saw like a direct hydraulic unit, the RGC S16 for example. thats the reason we always use the softest rings for concrete, they wear more but needs a lot less preasure to stay sharp. in brick walls we use the medium ring.

also cutting with to little water wears out the wheels faster!
do you use a 4,5mm (1,77") wide pre-cut disk to open up a 15cm (6") deep cut first? it really saves money and nerves!

we only use the ring cutter when it is absolutely nesesarry, when the concrete walls are thicker than 15cm (6") we usually mount the wall saw. the cost of using it is a lot cheaper and the amount of time is the same or less if you hit a lot of reinforcement.
but then we use the ring saw to prevent over cuts (in combination with the chain saw), and when it is not possible or nesessary to use the wall saw.

but then again, when thinking back to the -90's, i still remember how MUCH i hated the old ring saw!!! :mad:
i had to cut a 60m (196') long horisontal cut in heavily reinforced concrete at a steel factory, i will probably never forget that one...

I had a Partner ring saw and hydraulic powerpack years ago. You always needed new drive wheels and a tool box to keep it going. :mad:

this is only partly true...
it is a really good tool in the hands of a skilled PRO, but if you don't know how to do the correct regular maintanance and adjustments -> it will be a real pain in the a..
for concrete i recomend to always use the softest segment type cutting ring, and stick to the original Husqvarna diamond tools ring. there are a lot of "pirate" rings that are not the right materials and often even not soft enough.
and always put a new drive wheel on a new disk! and remember to relase the spring tenision everytime it's not in use.
the suport wheels are corectly adjusted if you can barely keep them from spinning with your hands, when you rotate the disk by hand! (with tenision on the springs). remember to shut off the power pack when doing this!!!

We don't own one single gasoline driven concrete cutter, we always bring our own truck with built in power packs and generators!

James,

I agree with the sawcutting breed, those guys make us demo guys look normal. To answer the question , i usually sub out any cutting that i can't do with a stihl demo saw and a walk behind cart. For wall cuts we bought a partner ring saw which will cut 10", but i warn you that the amount of time you cut with the saw is tripled by the time you spend wrenching on it.

This post is speaking my language:)

James....the 'same tree'??? Surely, you jest:D

It appears by the few posts that pricing isn't the primary issue (although an obvious factor) rather dependability matters. Dependability does require a conscious investment in each project from accurate and knowledgeable bidding to pre-planning and safe execution. Not every apple in the orchard is capable of this.

So.....Here comes the obligatory plug.

If you seek a top shelf, professional, dependable, safe, capable selective demolition contractor, please feel free to contact me either through a PM or by email [EMAIL="rolson@concut.com"]rolson@concut.com[/EMAIL]. Our firm has developed and continues to develop state of the art equipment. We are not your average concrete cutting subcontractor.

Best regards,
Rick

I sub most of the larger amounts. I do have one of those Stihl walk behind wetcut kits for smaller slab cuts, but it isn't made for lots of continuous use.

We sub out most sawcutting but do most of our slabcutting. One of the hardest things was finding a good cutter who was dependable.
