Good morning. Please what if you are on a site where there's no building in the surrounding to locate the benchmark

Talk to a practicing surveyor in the area, or visit the engineering survey office of your local council. If there are no national established control points, then there will be Temporal Benchmarks or some sort of recognized secondary or tertiary control networks.

Please do a video on open traverse calculations😢

Thank you sir Got d gist behind it But my problem is how can we apply this onsite sir

Plz Plz TOTAL STATION ALSO START FOR OUR TEACHING, I NEED IT URGENTLY.

How do you get 86.452 from subtracting 0.394 from 88.846?

@user-qs7tm7iz4s

Actually that 88.846 should've been 86.846

Please you didn’t show the unadjusted RL

There's architects too you know

Your first RL and last RL is same, so that means you close your observation at OBM. Your Label must be same!

@@isaacchiagozie9648 I ended the reduced levelling (RL) task at the same Ordinance Benchmark (OBM) [primary control point] station where I started transferring levels on the site ground. You can also start off from a Temporary Benchmark (TBM) [secondary or tertiary control point] station. If I had ended at a different station, I should be getting a value less than or greater than 0.000 in my final checks. But no matter how you ended your RL on that site, if you have carried out your levelling observations accurately, the final check should definitely be fine. I hope this helps. I will be making more videos on this and more subjects.
