Hi guys

I've started doing more staking out these days. I always submit a report to the contractor of that day's work to prove that the staked out point were in the correct places when I left site.

I still haven't settled on the best way to report what I've staked out.

One way is to have an Exel spreadsheet of points with design co-ordinates, as staked out co-ordinates, and the differences. The report is presented within a pdf so it can't be altered.

Another way I've used is to send a pdf copy of a CAD file that shows the design points or lines, the as stakeout out points or lines. I annotate (as a dimension) the difference/delta.

I'm spending a lot of time doing these reports and wondered if there is a way so I can make better use of my time. What do others do?

I use Trimble S7 along with a TSC3 and so I could use the Access stakeout report function but for one reason or another I haven't done so far.

Cheers, Andrew

When we staked endless water main, sewer and sanitary, we had cut sheets that were given to the contractor. I think a weekly report is good enough, and what you are doing is all well. But far and above what the contractor needs or wants to know. If it were me, and I run my own firm, I would submit a memorandum issuing the days results without any coordinate data or map. A simple and clear explanation of the days progress into the job. Heck, I might do a weekly report with a more in depth report, but certainly less than you have described above.

 

As long as you’re staking to plan, and you can prove you’ve done so properly, you’re doing right by your client.

Have also a look at the custum stake out report that should be on the TSC3 by default, that may already do what you want without an extra effort.

If not present yet check for Style sheets on the Trimble Access Support site.

Are others using the stake out report on the TSC3? I found it a bit simplistic and wasn't sure how helpful it would be to contractors.

Like David said, far and above what the contractor wants. They won't look at it. The assumption and expectation is that it's staked correctly. Keep the data so that later if it's questioned you have it to back you up.

Cut sheet and point plot is all they want.

A cut sheet shows cuts/fills of as-staked elevations compared to design elevations. Provided to contractor as a backup to markings on stakes. See Norman Oklahoma's post of January 8, 2020 3:23 pm for a nice example.

Point plot shows the plan view depiction of the as-staked points.

I'll save you the search. Here is an example cut sheet.

And here is a point plot to go with that cut sheet. The superintendents really like the point plots. Sometimes I'll just take a red pen and sketch the points on the plans. That seems to make them just as happy.

I agree with others - a contractor will not look at your coordinates. He would not know what he was looking at if he did. But if things should screw up his attorney's forensic analyst might find something in it to use against you.
