In some areas around here the municipality does require stakes in the hole, they consider it a recertification which makes no sense as nothing is there to certify, but them's the rules. Usually I'll just give them three corners and they're good to go. I don't mind this as its part of the plan and scheduled as such. Its when the concrete guys are just lazy that it honks me off. I normally wont set the house at minimums so it really isn't that picky unless the inch guys did the layout.
There is one Village down here where I have to stake for digging, then for the footings and then again on the footings. Then I have to go back again and certify the walls. Every job, even if its many feet away from minimums. That can be a pain and nobody like the invoice after that circus.
Usually I'll just give them three corner
Isn't that 4th corner pretty important for your and their check?
@bill93?ÿ
We always give every corner but occasionally the hole wasn't excavated far enough, luckily the formers here are pretty good with a measuring tape so as long as they have the other 2 corners to measure off of that one missing corner is pretty easy to lay out since they have to have plans with distances anyway.?ÿ
I'm confused about why we would do their job for them?
It is about adding value by your service. You assume that the forming crew can figure those little problems out on their own. Frequently, they can't. Or won't. If you can lighten the foreman's load by popping in a few more hubs then you are more likely to command premium pricing, and get more calls for new jobs and referrals.?ÿ If you get yourself a rep for blowing and going expect to be amongst the first to be short on work when the downturn comes.?ÿ And it will come. I expect it sooner than later.?ÿ
Plus, it is a lot less stressful to put in some extra hubs than to come back to explain how the slab got screwed up even if it isn't your fault.?ÿ
@bill93?ÿ
Not really Bill. The guys around here just want to be able to square it up in the hole which is where the 3 corners come in. Now if its one of the stupidly designed projects were every possible square inch is being built on then the answer may be different but I don't get too many like that anymore. And in that case I'll put three points in the hole for the footing and set more points on the footing after its poured because whatever I would set for the footing would disappear anyway, while something set on top has much more value to everybody. A lot of what I get is a house set in the middle of an acre or more lot. If something does go wrong no one cares anyway and sometimes I've had the owners/contractors move or twist the building without telling anyone.
Quite a few of the contractors around here have their own stake out crews running robots. They just need a hand to get started and then they take it from there.
Set HLT at PL at BLDG line ext. 8 hubs total assuming the offset to CL is the same. Elevate all of them and that's it.
?ÿ
One way to do it anyway; maybe hem back the corner lot offsets for convenience.
I stake big complicated houses on 50-70% grades a lot. One house I staked for excavation 4 times before they got the first footing poured. Big house, small lot, steep grades, no where to put the dirt. Then I was back another 5 times staking for excavation, footings and then pin the walls in different sections as they were built. The builder and owner's rep were very happy I saved them so much trouble.
More often I encourage builders to set up the batter boards. Then I STAKE LINE in SurvCE to quickly get the Station (distance to the corner), Offset is 0.00 and CUT/FILL to mark on the batter board.?ÿ ?ÿ

@bushaxe I work primarily in setting up all the construction layout my firm does and we do allot of it.?ÿ To stake what you mention, I would set 10' perpendicular offsets at each corner, setting stakes with tacks and a lath at each stake, then provide cuts/fills to the top of slab on all eight points.
I do the same with redidential building construction, stake the box (building envelope) and then provide 10' perpendicular offsets at eact of the four corners with cuts/fills to first floor.?ÿ

Unfortunately I think at this point all of our customers and the formers working for our customers would see the most value in us getting to the site in a reasonable time. They don't want us spending needless time giving them stuff they don't need..
We're booking into next year for any new projects (so are the only 2 other survey companies in the nearby area as far as I know). We have people ticked off at my PM just because they have to wait longer than they'd like. There is too much work to get done and has been for a couple of years now.?ÿ

Accepting what is available isn't the same as getting what you want.
I think at this point all of the trades are pretty used to accepting what is available, since there are shortages in almost everything these days. Not too long ago they couldn't get floor joists.?ÿ
@350rocketmike?ÿ
Your original question, which I answered, was "Why would you do that"?
?ÿ
You are right, my comment may have been irrelevant if the op is also not as busy as us. I remember years back our boss used to bid on jobs. I think now the jobs just come non stop.?ÿ
5 off and 10 off both ways at 4 corners, 16 stakes. That??s what our carpenters want but that??s in-house. One pin at finish floor elevation anywhere out of the way within view.
That is excessive.
That is excessive.
Dave works for a government agency. If those carpenters had to pay for his service they might give their wants some thought.?ÿ?ÿ
As I recall the OP is on the coast..So four corners of the big box and a TBM. When I put offsets in out there, they concrete crews would get confused. I would be more worried about the 3' from the property line and the fire protection line issues. Zoning can explain that one to you (don't bother with calling the fire department as they don't know).
?ÿ
I also reread your post....On top of the fire protection line, you also have less than 10' building separation which means different fire rating building methods and special variances as most muni's at the coast require 10' building separation (zoning code in general and I believe in state fire code).
It's been a while since I have done any kind of construction staking and I need some guidance. I have been asked to stake 4 corners of a 40'x20' rectangular concrete pad for residential construction. Is it standard to set a hub and tack offset in each direction at each corner with a guard stake noting the offset from the corner? The site is flat. The slab is to be graded at 4-inches above the adjacent sidewalk.?ÿ
Pin the four corners and hub & tack offsets, typically 10?? in your scenario. Drive a pin set to finish floor near one of your offsets. Write hub elevations on your 10?? o/s protection stakes for back-up.
Edit: if some of the offset hubs are wiped, there is usually enough for the contractor to recover layout. It is worth the effort to install them.
