There are many factors which affect the required balance since each and every project is unique. As you can see, the volume of excavations in this type of construction is not necessarily equal to the volume of total filling. If material from site excavations is not enough to fill the embankments, the engineer may order the contractor to import filling elsewhere. You use the material list to generate quantity takeoff tables and reports.
After you create a quantity takeoff criteria, you can apply it to a sample line group to create a material list. This filling is mechanically compacted to the required AASHTO density in layers not exceeding 300mm. To create a new quantity takeoff criteria Create quantity takeoff criteria as the first step in analyzing sectional material volumes. As much filling as possible must be obtained from the excavations. construction-material-take-off-sheet-sample-excel 1/5 Downloaded from on Februby guest Read Online Construction Material Take Off Sheet Sample Excel Thank you utterly much for downloading Construction Material Take Off Sheet Sample Excel. The excavated material is deposited down the slope in the valleys to create manmade formations known as embankments. How much earth requires to be cut from the slope depends on the elevation of the proposed road, its width and gradient of the hill slope. Vehicles are capable of moving on this road as if they are on flat ground, although the road may be at higher elevation than normal ground. The purpose is to cut the slope to create a surface that is level or parallel with the sea level. When building a road across a hill slope, open face excavation is required.
EARTHWORK QUANTITY TAKEOFF EXAMPLE UPGRADE
“ + “ walls / cross walls – Wall breath measurement should be deducted to the total length of centreline.Roads on Hillside Slope in Ladd Canyon, Oregon, USA – Upgrade of the I-84 Fish Passage – Photo Credits – Oregon Department of Transport “ T “ Junction – Half (1/2) breadth wall measurement should be deducted for a T junction. “ L “ Junction – There is no need to deduct from total centreline length. So there is o need to add or deduct anything to the measurement when takeoff quantity. But the measurement of blue coloured area will not be included in any instance such as when calculate the measurement of yellow coloured area or when calculate the silver coloured area. Here the green coloured area will be calculated twice when takeoff quantity. So the green coloured area should be deducted once from the measurement when takeoff quantity. Here, the green coloured area will be calculated twice when takeoff quantity.
But the calculations should be carefully noticed in junctions or cross walls such as L, T or +. Here, the center line is multiplied by breadth and the height to take out the necessary quantity (center line X breadth of wall X height). The center line act as “length” for calculation of an estimate by this method. But the method is more suitable if the offsets of the building are symmetrical. This method is easy or quick as to calculate even from work site.
This is another method of taking out quantities for construction estimation. Length of long wall measurement decreases while length of short wall measurement increases, when notice the measurements from foundation to super structure.Ĭalculate the quantity of excavation for the given plan using long wall – short wall method? Short wall length in-to-in = c/c length – 1/2 breadth on one side – 1/2 breadth on the other side Long wall (out-to-out) = c/c length + 1/2 breadth on one side + 1/2 breadth on the other side
