An in-gin-ear just asked me how many hubs I can set in a day. I just don't do enough construction staking to know. What's a reasonable estimate to the number of hubs w/tack one can set in a day including shooting elevation? The site is wide open and grubbed, and I am not aware of having to dodge any equipment.
Hubs for what? If tacked, I hope it's not untility layout. Even tacking C/G stakes is a waste of time.
TDD Says -- 100 / Hr
That Equates to 1,300 per Day
At least that's what Ted might say if he had not been banned by the overseer
Depends on many things, need to determine the intent and the conditions along with crew and equipment. If he is looking for a cost figure, tell him that without the details and a site visit, cost plus.

Assume 8 an hour...that should be about average.
> An in-gin-ear just asked me how many hubs I can set in a day.
I think I would run as fast as I can if asked this. I prefer my staking to be done in small doses.
I've done as many as 130 in one day. However, I felt it for a day or two. 100/day is a good lick for finish staking, that includes offsets.
What equipment are you using?
How many on a crew?
I set 75 pile points, in a basement, with a helper, using RTK GPS, in 2 hours.
In 1978 I was the rear chainman on a 3-man crew that set all of the hubs for pavement in a subdivision, 10,000', in a 10 hour day. Every 50' in tangents and 25' in curves about 1/3 of it curved. It took 8 hours the next day, to shoot elevations and mark the grades. We used a T16, 100' steel tape and a lenker rod and level.
A 2 man crew can fly with RTK in open skies or almost as fast with a robot, depending on set ups. Your mileage will vary.

For staking curb and gutter, I've done as many as 100 a day. Those days are few and far between. The 8 and hour figure isn't bad, that about 64 a day, and you should be able to do that every day.
I'm not real fond of construction staking. We are doing building corners for rough grading and Curb & Gutter. The in-gin-ear is going to be the one pounding the hubs, so we probably won't get much work done. 😉 I am pretty sure we can do 50 to 60 per day easily after thinking about it. RTK maybe for horizontal position for rough grading stakes, but will use differential leveling for marking cut and fill.
If you've got a robot and about an hour to calculate it, you'll go faster and kill two birds with one stone.
depends on the job... 25 in two hours for radial house staking is average... so does that mean I can do 200 a day, I doubt it! (OK, maybe with a helper)
Everybody here has a project (or projects) in his head and is thinking about what he did then.
This is a w i d e l y variable number, depending upon many factors.
A robot and a two man crew can burn through hubs. One staking and one driving. This is the only way we do construction staking now.
Pegging house blocks average over day 12 hour.
Depends on size of set out area.
Setting stakes with rl tapes on for set out for roads and sewer 15/20 per hour.
I used solo and did all myself.
Actually did more than conventional 2 man crew. There again I owned the surveying practise!

1 every 5 minutes with about 10 minutes out of every hour for distractions make 10 an hour. If you have 45 minutes at each end of the day to load/unload and drive time you should get about 65 in a 8 hr day - if you are working at maximum efficiency.
Reality says that a surveyor that doesn't do much staking being helped by an engineer who hasn't done any is not going to achieve maximum efficiency. So figure maybe 75% of maximum on a good day.
For reference, I set about 40 sanitary and storm stakes in 8 1/2 hrs yesterday. Rained hard all day, had a battery issue, 3 setups.
Yes, your mileage may vary. But the answers got me thinking about it enough that I think I quoted a realistic number. Besides, we will probably have two crews on it, so I am sure we will make some good time.
Wish I had a robot, but not in the cards right now.
And for what its worth with regard to using the engineer on the field crew, at a small company, you get used to doing stuff outside your occupational specialty to get the work done.
It all depends on how hard the ground is and how accurate they need to be set...
Figure your estimate based on 50 per day. Shoot for 75. Bill hourly.
How many hubs in a day...very loaded question...
This definately depends on the job and crew and equipment way too much to give an answer for every situation.
Back in the day...(you rememeber that mythical day, don't you?"...with a Sokkia Set3 and an SDR24, 2 guys...we used to get a hub set and graded and marked every 3 minutes on jobs where the stakes were reasonably close together...like curb stakes..
With a Robot or RTK...the time shrank to around 1.5 minutes per stake.
Seems like 300 or so was the most we ever set in one day.
We were good and fast...but not supermen.
It still took time to flag laths, get hubs loaded into bag and all that.
