Plans have arrived....and so it begins
Posted 18 June 2012 - 10:51 AM
I figure it should be pretty easy to get quotes from the local lumber yards on the wood and such, but I've never dealt with concrete before.
The built site will be about 200-250 feet from where my driveway ends and I don't have a really clear path for a truck to pull back to the site (nor would I want to if I can avoid it). Has anyone dealt with concrete being pumped a similar distance? Does it significantly increase the cost? I'm hoping I'll just need it for the piers (yes, more than one) as I'll be going the deck route and I can set the posts myself with a power auger and a bag of Quickcrete in the bottom of each.
The piers will each be at least a cubic yard, but I may go larger if there is a minimum order or something.

I'm really not up for hauling and mixing the amount of concrete needed for my two pier bases though (at least 45 80# bags per pier)

Ouch. First quote for excavation and concrete for the 2 pier bases (3' x 3' x 3' each) is $1200 - $1500. Does that sound right? At that rate I'll blow through my budget in no time
Grab a shovel..or better yet pay some kids to dig the holes....they like digging for milk money.....

Thanks Mary. That's more in line with what I was thinking. He said even if I dug the holes myself it would still be over $1k.
Well, I and my daughters old boyfriend dug my 3.5x3.5x6ft hole and I payer $330 for 2.5 yards.

I was in residential construction for years. The customers who complained the loudest about prices were the weekend warrior types. I wouldn't even dream of pushing several cubic yards of concrete 200'-250' in a wheel barrow in my best days. They'll probably use power buggies to do it. I'd kiss every foot of earth getting back there just to find someone period that would do it for that price! I'd pay that in a heartbeat and get on with the next phase. Observatories aren't cheap at least the better ones. Mike
Like you said, his cost is most likely *delivery*...getting it to the site.
Are you saying my Observatory is a cheep, flimsy, shack cuz I saved loads of money and didn't ring up a big bill?
Is that what you are sayin....huh? Bro

The concrete will definitely be done by someone else. As you said. Moving and mixing 90+ bags of Quikrete is just not in my future.
I envisioned the piers being steel piers bolted to the tops of the bases. Perhaps a 3' cube of concrete topped by a 1.5' square 1' high to bring the top of the concrete near the level of the deck. The steel pier would then be bolted to the top of this and extend up through the flooring.
Sound about right?

Concrete poured, I am lucky and the truck could back up to my site
Pier is 6 feet of 8 inch 1/4 inch wall aluminum tube in compression
Pier mocked up in the house
Hope this gives you some ideas.

All in the details. You may find one contractor will pump (there is usually a minimum load for these follows), another might roll an electric mixer over. Access and labor wrt access can often be a significant contributor.
Locating on clay I'd want some sort of survey before starting - might need some sort of bedding and/or drainage - but a lot of that depends on your location and build site and if no permit required, you.

I'm leaning toward doing the digging the holes myself now. Since I planned on renting a 12" auger for the structure posts I figure I can use that to remove a large portion of the earth from the pier area then remove the rest by hand.
There is no permitting required in the township where I live except from the zoning inspector. No building inspector to be seen.

Dig the holes myself with help of the auger to remove a good portion of the earth. Cart it all away to the back corner of the lot.
$365 for delivery of 2.5 yards + $100 rental of concrete buggy to shuttle the stuff back to the site.
What do you guys recommend for the pier base shape? Just a square with the mounting bolts at ground level or should I raise up a portion at the center of the base to have the mounting point higher than the grade?

Exciting times, eh?
The warm room will be about 8 x 16 (minus wall thickness), leaving about 16 x 16 for the scope area with 2 piers.
My reason for going with steel piers is the ability to change things up relatively easily if my needs change down the road. If I need to change pier height, it's much easier to do by altering the steel pier or just making a new one if need be. Having a couple metal workers in our astro club doesn't hurt either
What sort of obs are you planning?

Exciting times to say the least, been planning for almost 2 years but looks like this is the summer work will begin. I just looked into steel pier pricing....OUCH! I definitely get your point on the aspect of changing things up as needed, with concrete piers, that would be VERY difficult. I'd like to keep in touch with you as you continue on with the project if you don't mind.
