Calculating The Numbers Of Blocks You Need For Your Fence by Nobody: 11:07pm On Jan 15, 2015 |
The Simplest Way To Calculate The Numbers Of Blocks U Need For Your Fence The simplest way to calculate the numbers of blocks you need for your fence project, assuming you are fencing a land measuring 120 feet by 60 ft, a standard plot This calculation is based on 9 inches block fence . The measurement we are using is 120 ft (length) and since we have two lengths that is multiply by 2 which is 240 ft. (120 x 2) = 240 The breadth is 60 ft and also since we have 2 breadths that equal 120 ft (60 x 2) = 120 Then (240 + 120) that is 360 feet perimeter line fencing. The calculation (we are to convert this 360 feet to inches ) since a foot is 12 inches , now let us multiply 12 inches by 360 ft which is 4320 inches. Now to get the line numbers of blocks that will go around the fence perimeters of 4320 inches or 360 feet, we would need to divide 4320 by 18 inches, since the length of any block be it 6 inches or 9 inches is 18inches. Now 4320 inches divide by 18 inches is approximately 240 line of blocks , then we must multiply that by the numbers of coaches of blocks you want for your height, assuming 7 ft which is 9 coaches that means 240 multiply by 9 which is 2160 blocks and that is all you need anything aside from this is fake and fraud, this calculation is derive by me professionally and i have been using it without any mistake, but always remember to add 10 % of blocks to it because of broken blocks, and for this work, you only need 30 bags of cements, one bag of cement to 70 blocks, is standard. for your pillars between the fence, let assume 6 blocks far from the next pillar, that means 6 divide by 240 which is 40 pillars, 1 bag of cement to 2 pillars standard, that is 17 bags plus 40 bags that is 47 bags is need by me to do this fence, if i'm in position and you should also to add 15 bags for floor blinding of the fence making 62 bags of cement. Then, we need to minus the gate and the pillars that are also taking space in the fence. The gate is 12 ft, let us assume the gate columns or pillars is 14 inches each, we have 2 pillars holding the gate, that is 28 inches or 2. 4 feet plus 12 feet that is 14.4 feet or approximately 15 feet. Remember we already calculate the pillars that 40 pillars is need for the measurement. Each pillar or column for 9 inches concrete is 9 inches square, 9 x 40 = 360 inches that is (30 feet + 15 feet = 45 feet ) / 18 inches = 30 blocks multiply by the number of coaches, 30 x 9 = 270 block minus 2160 blocks = 1890 blocks in total. 40 lengths of 12mm iron rod, since one pillar is equivalent to 1 length. 3 lengths of 16mm iron rod for the 2 big pillars holding the gate. 90 planks of soft wood for the framing. 1 truck of granite (granite would be use for the wall foundation and columns) 5 trucks of sharp sand Thanks for the opportunity giving me to explain this simple arithmetic.

HsLBroker: observation please, 120ft plus 240ft=360 ft 360ft x12 inches= 4320 inches/18inches= 240 lines of blocks 240 x 9 coaches=2160 blocks as for the cement it is 2160/60=36 bags for 6 inches while for 9 inches it is 2160/50=43 bags of cement for 9 inches. please cross check, i stand to be corrected. 28 Likes 2 Shares |

Very good and concise write-up by Mr. HsLBroker. Nice summary and corrections made by Engineer Segzy14. I hail both of you for contributing immensely to this forum. It will even be more helpful if you can tell us the tons of sand needed, and the bricklayer/help labor to set the blocks. Thank you. Now if we can have it on Front page, it has all been Politics lately. Hajji M. 10 Likes 1 Share |

Nice one,but it seems you did not leave room gate,which could actually reduce the amount of blocks from one end of the 60s. Good job though. 7 Likes 2 Shares |

euromilion: You are right. I was about to make this comment too. I have fenced some of my projects, and I keep getting arbitrary quotes. It occurred to me, there should be a standard way of calculating the amount of materials required. I am going to make a copy of this, print and laminate it! Some of the masons I hired love to argue. They will tell you that the job doesn't get done by simple arithmetic. Well, the truth is, simple arithmetic/calculation/estimation is the bedrock of building and other technologies. A thousand thanks for this posts! 20 Likes 1 Share |

mufutau55: for the bricklayers fee it is 2160 blocks x 50 naira/block = 108,000 naira. it all depends on your bargaining power it can be 45-50 naira per block. 5 Likes 2 Shares |

euromilion: as for me there is no need to leave room for the gate since i didnt add the percentage for breakages. i mean i was supposed to add some percentages for breakages, since i did not add it,that is why i didnt leave room for gate to compensate for it. 6 Likes |

2 blocks = 3 ft 120ft X 2sides + 60ft X 2sides= 360ft / 3 ft= 120X2blocks=240blocks X 9 coaches= 2160 blocks. #SIMPLEST# 51 Likes 6 Shares |

tunad4rari:1 truck of granite 30 tons (granite would be use for the foundation footing and columns or pillars) 5 trucks of sharp sand excavation of the foundation should be 600mm or 1.9ft or 0.6m sorry for the late respond, the thread disappear and i never knew when it appear again i don't know how or why but all the same is here again regards Adeniyi 08182481552 09039992385 10 Likes 2 Shares |
