This calculator will calculate the volume of excavated material using the length and width of the excavation in feet and the excavation depth from an average of four points It will calculate the volume increase of the material using the swellbulking percentage from Bank to Loose volume A dump truck holds anywhere from 10 to 14 cubic yards of
Jul 16 2020 At Wt Lt where Wt and Lt are the width and length of the top of the excavation In our example Wb Lb 5 and Wt Lt 15 so Ab 5 5 2 5 and At 15 15 225 and D 5 Therefore the volume is 542 cf or 200 cy This is 15 cy more than the 185 cy we calculated using the average width and length or 8 more
The ratio between compacted measure and bank measure is called shrinkage factor SF Compacted cubic yards CCY SF Bank cubic yards BCY Shrinkage factor is either estimated or obtained from job plans or specifications which show the conversion from compacted measure to bank measure
The units used are customarily bank solid measure the volume of material in place insitu In dealing with haulage units however loose broken measure the volume of material after excavation is employed If actual values cannot be obtained the following approximate measures of specific weight may be used 09122015 17
The volume of soil to be removed when excavating for a basement is actually smaller than the volume of the soil after it has been removed This is because the untouched soil measured in bank yards becomes less compacted when it is disturbed The less compacted soil occupies more space and is then measured in swelled yards
Excavation and embankment cut and fill Excavation the removal of soil or rock from its natural location Embankment the placement and compaction of layers of earth or rock to form a roadbed of the planned shape density and profile grade Various sections of
The life of dirt on a construction site is a violent one Say that we excavated this 3704 cy hole and trucked the dirt down to one of the goals Once we finished stockpiling the 3704 cy of dirt you get out a wheel a tape measure or a survey instrument and measure the volume of dirt laying loose in the pile It measures 4260 cy not 3704 cy
Nov 20 2015 Before the excavating begins the field engineer creates a grid over the entire area where the excavation is to occur Elevation data are collected at each of the grid points and recorded for future reference At any time during the excavating the field engineer can reestablish the grid and determine new elevations for each of the field points
Common Types of Excavation 1 Cut and Fill operations A Large projects dozers scrapers rollers and water trucks and graders B Small projects grader or bobcat 2 Basementtype Excavation track backhoe or track loader and dump trucks
To use a bulking factor number you have to multiply the bulking factor number by the excavated volume size For instance a bulking factor for Clay and Gravel is typically 115 If your excavation was 15 m3 Your volume size would be 115 x 15 1725 m3 You must consider the bulking factor of the material you are digging to ensure you
Width of the excavation Depth of the cut Material type Working radius for digging and dumping Required bucket dumping height Excavator Trick of the Trade 1 Step 1 Determine the bucket fill factor based on the material type Using a chart or it will be given Lacking any other information use an average of 85 percent Step 2
Sep 06 2011 The difference between normal excavation and bulk excavation can be defined by the amount and area being excavated and and the volume of material removed A simple excavation example is when a

BCM Bank Cubic Metres CCM Compacted Cubic Metres LCM The best way to visualize LCM is to picture soil in the back of a truck or even better in the conical stockpile at the end of a stacker conveyor This is the idealized version of LCM As we proceed with this discussion you will

material for bulk earthworks due to the high organic matter and contamination by other materials eg rocks and timber Topsoil can only be removed once clearing and grubbing and disposal of materials has been completed and sediment and erosion control measures
Soil or rock from the borrow expands when dropped on the lorry or the landfill or stockpiled One cubic from the borrow does not translate to one cubic dump Bulking or swell factors for some materials Material Density at the Borrow 103 kgm3 Bulking Swell Factor
Guidelines for Uniform Temporary Marking of Underground Facilities OneCall SystemsThe OneCall damage prevention system shall be contacted prior to excavation Proposed Excavation Use white marks to show the location route or boundary of proposed excavation Surface marks on roadways do not exceed 15 by 18 40 mm by 450 mmThe facility color and facility owner identity may be added
Jun 15 2021 In addition some jurisdictions have not defined soil types but do require preventative measures when an excavation reaches a certain depth or proportion When a soil type is defined the purpose is to try to identify or predict the potential for the soil to move and cause a collapse while the work is being done Soil types typically use a
If you know the soils load factor L you could calculate this as a ratio of bank measure volume to soil load factor L Shrinkage Calculations Shrinkage is the decrease in volume of earth once its been replaced and compacted compared to the volume of dirt in its natural
