    Thanks man. I'm actually a computer nerd not a surveyor, I'm just trying to educate myself but if you know how many survey points you're taking you can program Excell to do all the math for you. You seem to be familiar with spreadsheet programs but there is so much more you can do with it... even incorporate your data into a 3d graph. I hope this was as helpful as your video. Thanks again. Very helpful.

    Hey mate not sure if you'll respond but why does the total sum of rises and the total sum of falls equal eachother? any reason for that?

    • @Buildsum
      @Buildsum  2 ปีที่แล้ว

      Hi Mate, they only equal each other when you have a closed survey, starts and finish at the same point. Therefore the rise and fall have to equal eachother. Hope this helps.

    Firstly great video, gives a good refresher lesson. My question is what would an allowable error be between the three checks, 10mm?

    • @Buildsum
      @Buildsum  8 ปีที่แล้ว

      Thanks bssk1337, There should be no error between the 3 checks if there are then you have done something wrong with your calculations. An error of up to 5 mm would generally be acceptable for the reading however this depends on the number of readings that you take, distance and change in height over the survey run.
      Hope this helps

    Hi Buildsum mate, just quick one i did a survey from the front of my house to the back of my house (through the garage, changing about 3 times to get all corners) i turn out to have 2mm difference in my b/sight-f/site and my rise and fall. Is this just a coincidence as i did not start and finish at the same point, or is it just telling me my block is flat from front to back? Thanks again great vid mate!

    • @Buildsum
      @Buildsum  4 ปีที่แล้ว +1

      Hi mate, as long as the check on the level book are good then it must be right. Where you measuring at the corner of the house of just out in the yard?

    • @united3689
      @united3689 4 ปีที่แล้ว +1

      @@Buildsum Just out in the yard! Not the slab which id hope is flat :) I basically wanted to see what fall i had on my stormwater pipe from the kerb and channel in the road, to my upstream pit in my backyard. I suspected it wasnt going to have much fall but this suggests dead set flat....So i was just puzzled. So the check you do should be the same regardless if you dont stop/start at the same point? That is if you do points A - B -C -D and finish it should be the same checks as if you did A - B -C -D - A again? Thanks alot for your time by the way

    • @Buildsum

    if i want to level the area round a building, lets say the fenced compound is kinda slopping unevenly, so i want to use a level to correct this slope and cos water to flow from one part to the drainage.... how can i do this..
    am thinking if i round a level, round the area, then obtain the highest point say (3.459) and the lowest point say (1.256), if i add this and divide by the number of points or stations (say 15 points run the compound), so if i do this maths, i should have a value say 0.314, then i can slope the are using a constant value of 0.314m. so the new height of the highest point will be (3.459-0.314m) which will yield 3.145m. i can slope the entire area by a constant .314m.. can this calculations be right.. ideas are welcomed.. thanks

    • @Buildsum
      @Buildsum  8 ปีที่แล้ว

      Hi Marshal
      I would work out the differnce between the highest reading and the lowest reading so 3.459 - 1.256 = 2.203 then devide this by 2 so 2.203/2=1.101 The add this to the lowest reading or subtract from the highest So 3.459-1.101=2.358 this would give a reading for the average height across the block.
      Alternatively you could add up ALL of your readings and then divide by the number to get your average, this would be more acurate

    Does anybody know what to do when the IS is a minus number, do you still just take it away or...?

    • @Buildsum
      @Buildsum  4 ปีที่แล้ว +1

      Hi Alex, if the number in the Level book is a negitive this means that point where the reading was taken is above the Line of Sight (Collimation) of the instrument. This is done by inverting the staff and taking the reading upside down and recording it as a negitive. If you minus a negitive figure you are effectively adding it on e,g, 1.120 - - 2.355 = 3.475 giving you a rise.
      Hope this helps

    • @Buildsum
      @Buildsum  9 ปีที่แล้ว

      Kkae Ong Hi Khae
      The intermediate sights are additional readings taken from the same position. They are the same as the foresight and the backsight it just that the foresight and backsights are used to calculate the difference in height between to different positions that the readings are taken from. if you didn't have any intermediate sights that's ok but you have to have foresights and backsights.

    what if it doesn't zero out

    • @Buildsum
      @Buildsum  8 ปีที่แล้ว +1

      Hi Eric
      If your survey started and finished at the same spot then you should get all zero's, depending on how accurate your reading of the staff was. If they don't then the amount should only be very small say 5 to 10mm and it should be the same across all three checks.
      If the 3 checks are different then there is a problem with your calculations. What is acceptable depends on the number of reading that you have taken, the rise and fall of the survey and what degree of accuracy you require for the end product
      If you didn't start and finish at the same point then you wont get a zero however all three checks should be the same.
      Hope this helps

    Hello Buildsum, Gr8 video! One query though.. When you are observing the levels two points from the same reference point and one gives you a lower value, doesnt it indicate a fall? as in the vid above, first two points : 2.050 and 1.970.. observed from the same datum. 1.970 must be lower than 2.050. But How come 1.970's RL is greater than that of 2.050? Isnt the first set of difference values coming under fall and second set under rise?

    • @Buildsum
      @Buildsum  9 ปีที่แล้ว

      Monis Raza Hi Monis I'm glad you like the videos as for your question as the ground rises the reading on the staff will get less therefore a reading of 1.000 would be higher on the ground than a reading of 1.200.
      Therefore the lower the reading the higher the ground
