We calculate the number of homes supplied with READY-FRAME® using our average board footage processed per house, which is based on our 2019 READY-FRAME® saw production data and our 2019 data of actual homes produced with READY-FRAME®.The structural building components association (SBCA) study "Framing the American Dream" ( /fad) found that stick-framed structures use 25% more lumber than manufactured components. An independent third-party study found that the lumber reduction from homes built with READY-FRAME®, compared to traditional stick-framed homes, equals approximately 7.8 trees per the average size US home of approximately 2,300 sq. Keep in mind that not all gravel needs to be compacted, and some varieties compact more than others, so this much additional material will not always be required for every project.1 Calculation based on production data for Builders FirstSource READY-FRAME® precut framing packages and roof and floor trusses since January 1, 2019. In the above example, 5.7 tons is necessary to include overage, but to account for compacting, you would need roughly 6.8 tons to make up the lost volume. Therefore, after accounting for overage, you will need an additional 20% of material to account for the volume lost during compacting. This compacting can lose as much as 20% of the total volume you wanted to fill. Gravel is also sometimes compacted prior to other materials being placed on top of it. To account for these, it’s generally a good idea to order an additional 10%.įor example, if your calculations call for 5.2 tons of gravel, you will want to purchase 5.7 tons to account for necessary overage. In addition, if you are backfilling an area with gravel, there may be voids that you have not accounted for, which will increase the amount of gravel needed to complete the job. It may slip off your wheelbarrow or spill from the back of the truck prematurely. For example, some gravel may be lost when you transport it to the final site. In most instances, it’s a good idea to factor in additional gravel or overage when calculating what you need. How to Account for Overage and Compaction MaterialĬheck out our stone and mulch calculators for estimating other landscape materials. Table showing how many yards per ton of gravel, rock, soil, and sand. The chart below shows how many yards are in a ton of gravel, rock, sand, and soil. Weight per cubic yard and cubic meter of gravel and other common landscape material Material The chart below shows how many tons are in a yard of gravel, rock, sand, soil, and other landscaping materials. Weight = cu yds × density weight min = 3.7 × 1.4 = 5.2 tons weight max = 3.7 × 1.7 = 6.3 tons How Many Tons in a Yard of Gravel Volume = length × width × depth volume = 10′ × 10′ × 1′ = 100 cu ft cu yds = 100 cu ft / 27 = 3.7 If the initial measurements were in feet, then divide the total number of cubic feet by 27 to get cubic yards.įor example, let’s find the amount of gravel needed for a space that is 10 feet long, 10 feet wide, and 1 foot deep. If the initial measurements were in inches, then convert cubic inches to cubic yards by dividing the total number of cubic inches by 46,656. If you measured in inches, then what you have is the volume needed in cubic inches, and if you measured in feet, then you have your total cubic feet. Multiply the length, width, and height together to find the volume of the space. Start by measuring the length, width, and depth of the area you need to fill in the same unit of measurement. Therefore, the first step to estimating how much gravel, sand, or soil you need is to estimate the volume of material needed. Both weight per cubic yard and the total volume are necessary to determine how many tons you will need to order. In addition to the weight of the material, you also need to know the volume of the space you are filling.
