Ouch!

[ForceFed70]

Just got my 1st quote for concrete work for my 32x40' garage. Footings, stem walls, and slab.

$20,000

Nothing fancy except 1 stem wall that has been engineered so that I can backfill to 6'.

My wife is going to hit the roof

Tell her outside

 

[tatra]

how much is concrete out your way?...........

 

[akdiesel]

$20,000. Thats rediculous.

"Tell her outside" and thats a good one.

 

[rasit]

Does it include layout, excavation, haul-off, stone, re-bar, concrete, backfill, grading ect? Costs can add up fast and merely giving a simple "Footings, stem walls, and slab." description for $20K may seem misleading. If it's just concrete, it sounds high and if it includes all of the above, it's a bargin.

The best way to estimate costs for a garage project is to research your *** off, get many quotes, add them all up, double it, add 10% waste. Give that number to the wife and don't ever speak about money again until you're getting ready to wire it up, and have to explain that it's going to overun budget.

 

[stafford]

Thats in the neighborhood of 5000 worth of concrete. must be on the of a big assed hill and lotsa work needed on the lot?

 

[green.bubbly]

Yep, I was shocked as well when I began pricing the concrete and finishing. Ended up paying about $14,000 for a 38x46 and a separate 24x24. Sounds like you had a good bit more dirt work to do. My land was fairly flat.

Comparing quotes was a *****. One would quote just labor, one would quote labor and material but no concrete, one wanted me to get my own sand and material. Just make sure that when you decide who to go with, that everything is covered.

If I remember correctly the cost for my 30 X 36 was about $15 000. That included rebar foam, pex, concrete, excavation, 'a' gravel, set up and finishing. Flat ground but did need a lot of fill 6 dumptruck loads I think) after removing the loose overburden.

The rest of course was cheap with no over runs

Good luck with your wife, I was only dating at the time and did not get engaged until after the garage was finished.

Ah ha too late, it's already built!

 

[sdetweil]

yeh, ouch.. I would have stopped if that was the cost.

I got a 30x40, 1ft thick on one side for lift, and 20x30 flatwork section (6 in thick with fiber) for $6000 total. I did pay $500 separately for 4 truckloads of fill.

If you mean a garage shell on a slab, that's dirt cheap in my neck of the woods.

 

[gabedad]

I can believe it. I had a quote for excavation / foundation/ slab 24x30 for 9500 - which was cheap - the guy gave us a good price because he is friend of my wife's ceo

However, when they excavated - there was too much loam - not enough fill. Ended up costing 4000 extra for fill and backfill of the foundation afterwards. I will have the slab poured this spring and a trench for electric. It's going to some some additional cash for the sand at the bottom of electical trench - so I can certainly see 20k canadian

Good night man! Frame the forms and lay in the rebar over a few week-ends. Arrange the help of a few buddies to help you do the pour. Take a day, or two off and do the job yourself. It's a garage for goodness sake, not a government building.

That's what I did, and it saved me THOUSANDS of dollars. The longest waiting time I had was waiting for the inspections. Somehow,

• even though I'm not a professional concrete guy,
• nor were two of my buddies,
  • we got the job done, there's no cracks,
  • no one's laughing at the concrete job, and
  • I didn't break the bank.

If you're not willing to do the job yourself, you'll pay through the nose to someone else for your decision. In my case I did a 1100sqft floor, 18" footings and foundation and a 1200sqft parking area for the cost of the concrete delivery. I'll add a few bucks onto that for the plywood and 2X4's/2X6's used to make the forms. Those were recycled into shelving inside the garage with very little scrap.

If I can do it, you can too, 'cuz you're smarter than I am. Of course I'm in the States, and that changes things a whole lot from you boys north of me in BC.

 

[holdover]

Wow, That is alot of money. here in SW VA I paid 115.00 per yard Rein. concrete(current cost 130 yd). Gravel is 245 per 16 ton delivered. My slab is 41' X 61' finishing fee was $1195 and that included cutting the groves in the finished pad a few days later, slab is minimum 6" with section where 4 posts lifts are, 2 of them, 8-12". I built 2.5 yrs ago steel rebar and mesh was a bit cheaper. I was a contractor with a backhoe so the excavation cost were just fuel and my labor. I is hard to compare a turn key job to a self built one, but when the cost of materials are subtracted from the total cost, it often reveals very high labor charges, not saying this is the case here, but just a thought.

 

[gabedad]

remember - he probably has to go down 4' for the walls. I had to where I am in mass

 

[GarageEnvy]

I know this discussion has been had many times and there are a lot of regional differences but this really seems high. I'm in California on level ground with no engineered walls. Excavation, compaction and pad prep for my 53'x34' was $1,500. Concrete work was $8,000. It was 38 yards. That was with the rebar and me just sitting in a lawn chair watching the show. It also included a pump truck of $650. That was a complete "guy off the street" price. I didn't have any connections in the business.

 

[tdkkart]

32x40 is roughly 20 yards for a 4" floor, at $100/yd is $2000, double that number for installed price so $4000, add $1000 for a 6" floor(50% more concrete)

Footings usually end up being as much or more concrete as the floor, as does the labor, so now we're up to $8000-10,000

The above numbers assume a flat level site with only minimal excavation work, but using these rough numbers usualy hits it pretty close, at least around here.

We still don't have the above ground stem walls, nor do we have any of the excavation/fill work on a site that is apparently close to 6' out of level. Which could again double the $$$, so I wouldn't be surprised with a $16,000 estimate, and I'm sure there are other items not mentioned that could easily account for another $4000.

Construction costs are high, and as simple as it seems "just double that" is a really typical response for any changes or additions.

 

[larry_g]

Another way to look at this. I have no idea what the concrete cost now that it has been down two years. I just enjoy the time that I have in the shop and away from my life at this time.

no neat sig line

 

[cashishift]

i'd probably get a few estimates.....

 

[Daddy_Rabbit]

I just had a 24' x 36' monolithic (4-5" thick) with a 4" curb all way around completed (whirlybird finish) and it was less than $5,000 for material and labor.

 

[ForceFed70]

Will definately get another quote or 2.

Excavation has already been done, but it was done in November so it needs a little cleanup.

Concrete is in the neighborhood of $180-$200 per yard. He figures that the job will require somewhere around $10,000 worth of concrete. He also figures $1400 for form rental tho which kinda surprises me. I'm pretty sure I could buy the material to make my own forms for less than $1400.

The $20,000 includes:
- Supply of all materials, gravel, rebar, fill, etc.
- Forming, pouring, and finishing of the concrete.
- 2' deep footings, and 8" thick stem walls (except for the engineered wall, that wall must be 12" thick with a 4.5' wide footing and will be 9' tall)
- 5" slab with rebar 24" OC. No foam or PEX. Power trowel finish.
- Drainage, weeping tile, and backfilling.

The guy is in the the concrete business has to rent forms? I'd think a concrete guy would own his own forms.

At least it used to be like that.

 

[sfckiddo]

i can see where they might not have the forms to pour a 9 ft. wall not something that they would do often.
