What Vitamins Should A 18 Year Old Female Take

It's essential for healthy bones, teeth, gums, and blood vessels. Ask your doctor if supplements are right for you.Vitamin EVitamin E is an antioxidant and helps protect cells from damage. It is also important for the health of red blood cells.Vitamin E is found in many foods, such as vegetable oils, nuts, and green leafy vegetables. It's also added to some breakfast cereals.Teens should get 2.4 micrograms of vitamin B12 daily.Vitamin B6Vitamin B6 is important for normal brain and nerve function.

It helps maintain healthy skin and is important for nerve function.You'll find niacin in red meat, poultry, fish, fortified hot and cold cereals, and peanuts.Teen guys need 16 mg of niacin daily. It is also needed to make DNA.Liver, dried beans and other legumes, green leafy vegetables, asparagus, and orange juice are good sources of this vitamin. So are fortified bread, rice, and cereals.Teen girls and guys need 400 micrograms of folate daily. Although more supplementation studies are needed, ensuring vitamin D adequacy throughout childhood and adolescence seems prudent.

The Linus Pauling Institute recommends that adolescents aged 14 to 18 years should have a daily intake of 600 to 1,000 IU (15 to 25 μg) of vitamin D, consistent with the recommendations of the Endocrine Society . According to the Endocrine Society, at least 600 IU/day may be required to maximize bone health, and 1,000 IU/day may be needed to increase serum levels above 30 ng/mL (75 nmol/L) . Given the average vitamin D content of the diets of adolescents, supplementation may be necessary to meet this recommendation.

The RDA of magnesium for those aged 14 to 18 years, 410 mg/day for boys and 360 mg/day for girls, was derived from results of balance studies in adolescents. Good dietary sources of magnesium include nuts, and green leafy vegetables because magnesium is part of chlorophyll — the green pigment in plants. Meats and milk have an intermediate magnesium content, with milk providing mg per cup . Although data are limited, some studies have found that a large percentage of adolescents have magnesium intakes below recommended levels ( ).

In an analysis of NHANES data, US adolescents who consumed milk had higher daily magnesium intakes than adolescents who did not drink milk . However, NHANES data show that US adolescents (12-19 years) on average only consume about 1 cup of milk daily . Low-fat milk, nuts, whole grains, and green leafy vegetables are important sources of magnesium for adolescents. If adolescents do not meet the RDA through dietary sources, LPI recommends a combined magnesium-calcium supplement. Specifically, data used by the FNB to determine calcium accretion came from a recent longitudinal study in 642 Caucasian adolescents aged 14 to 18 years . Thus, the RDA was set at 1,300 mg/day; this level of calcium intake is expected to cover the needs of 97.5% of adolescents.

Vitamin B6 is required for heme synthesis and in the synthesis and metabolism of amino acids— the building blocks of proteins. Thus, the vitamin has obvious relevance to adolescent growth and health. Dietary intake recommendations of vitamin B6 for adolescents were established by extrapolating data from adults, using metabolic body weight and accounting for growth. The RDA for boys aged 14 to 18 years is 1.3 mg/day, and the RDA for girls aged 14 to 18 years is 1.2 mg/day . Only a few studies have evaluated vitamin B6 status specifically in adolescents.

The same investigators found more than 40% vitamin B6 inadequacy when a group of 112 adolescent girls (12- and 14-year-old) were followed for two years . For information on dietary sources of the vitamin, see the article on Vitamin B6. The RDA for vitamin A is based on the amount needed to ensure adequate stores of vitamin A in the body to support normal reproductive function, immune function, vitamin A-dependent gene expression, and vision . Vitamin A intake recommendations for adolescents were derived by extrapolating the recommendation for adults using metabolic body weight, accounting for growth.

For information on vitamin A content in foods, see the article on Vitamin A. The formulas also contain vitamin D, magnesium and zinc which contribute to the maintenance of normal bone health. Vitamin C has a number of important roles during growth and development, including being required for the synthesis of collagen, carnitine, and neurotransmitters . Vitamin C is also a highly effective antioxidant and is important for immunity . Further, vitamin C strongly enhances the absorption of nonheme iron by reducing dietary ferric iron (Fe3+) to ferrous iron (Fe2+). Specifically, iron absorption is two- to three-fold higher with co-ingestion of 25 to 75 mg of vitamin C .

This has special relevance to adolescent health, considering the fact that iron deficiency is prevalent among adolescents, especially girls . The RDA for adolescents aged 14 to 18 years, which was extrapolated from recommendations for adults based on relative body weight, is 75 mg/day and 65 mg/day of vitamin C for boys and girls, respectively . As we've seen, the use of multivitamins by teenage girls can help them ensure that they consume an adequate amount of essential nutrients on a daily basis, especially when they don't eat enough of the right foods. Although multivitamins are not a replacement for eating healthy and making the right lifestyle choices they can certainly help young women stay on top of their health and aid their growth and development. By consuming the right nutrients from an early age teenage girls and set themselves up for success for the rest of their lives. The teen years are a time when parents often start to have less control over their children's eating habits.

Teenagers begin to eat more food away from home, have a bigger say in family meal choices and often snack more on foods that are high in fat, sugar and/or salt but low in other nutrients. At the same time, some teens may start to skip meals, experiment with vegetarian diets, eliminate food groups such as meat, dairy or carbs, or closely monitor what they're eating to control their weight or bulk up. The end result can be very unbalanced diets – often with too much saturated fat, sugar and salt but too little fibre, a lack of fruit and veg and not enough vitamins and minerals during this time of rapid growth. Severe iron deficiency leads to iron-deficiency anemia; anemia affects more than 30% of the global population . Adolescents have increased requirements for iron due to rapid growth.

In particular, adolescent girls are at a heightened risk of iron deficiency due to inadequate intake of dietary iron, especially heme iron; increased demands of growth; and iron loss that occurs with menstruation. Following puberty, adolescent girls have lower iron stores compared to adolescent boys . This may be of major concern in light of the sizeable numbers of subjects in many countries with serum 25D3 levels below 50 nmol/l, especially during winter. However, much of this evidence is from studies in adults and whether poor vitamin D status in childhood is a risk factor for these chronic diseases is less well understood. Moreover, the biochemical definition commonly used to classify an adult as marginally vitamin D deficient, or vitamin D insufficient, may not be appropriate for use in children and/or adolescents. The present review will begin with a brief recap of the physiological roles of vitamin D, and then will briefly consider the issue of defining vitamin D status.

Finally, some possible modes of addressing low vitamin D status in childhood and adolescence will be considered. Meat, chicken, fish, eggs, nuts and legumes (e.g. beans and lentils) are good sources of iron and protein. Iron is needed to make red blood cells, which carry oxygen around your body. During your teenage years, you'll start to menstruate, or get your period, and this leads to loss of iron. If you don't get enough iron, you can develop anaemia, a condition that can make you feel tired and light-headed and short of breath. Not eating enough protein when you are still growing, or going through puberty, can lead to delayed or stunted height and weight.

Include meat, chicken, fish or eggs in your diet at least twice a day. In general, multivitamin/mineral supplements contain only a small percentage of the RDA for calcium and magnesium; therefore, intake of calcium and magnesium from dietary sources, such as low-fat milk, is important. The amount of bioavailable iron in food is influenced by the iron nutritional status of the individual and also by the form of iron . Individuals who are anemic or iron deficient absorb a larger percentage of the iron they consume than individuals who are not anemic and have sufficient iron stores .

Although heme iron generally accounts for only 10-15% of the iron found in the diet, it may provide up to one third of total absorbed dietary iron . The absorption of nonheme iron is strongly influenced by enhancers and inhibitors present in the same meal. For instance, vitamin C strongly enhances the absorption of nonheme iron by reducing dietary ferric iron (Fe3+) to ferrous iron (Fe2+) and forming an absorbable, iron-ascorbic acid complex.

Organic acids, such as citric, malic, tartaric, and lactic acids, also enhance nonheme iron absorption. Further, consumption of meat, poultry, and fish enhance nonheme iron absorption, but the mechanism for this increase in absorption is not clear . Inhibitors of nonheme iron absorption include phytic acid, which is present in legumes, grains, and rice. Polyphenols found in some fruit, vegetables, coffee, tea, wines, and spices can also markedly inhibit the absorption of nonheme iron, but this effect is reduced by the presence of vitamin C . Soy protein, such as that found in tofu, has an inhibitory effect on iron absorption that is independent of its phytic acid content .

However, when accounting for intake from fortified foods, less than 5% of individuals in that age group have intakes below the EAR . The US Food and Drug Administration implemented legislation in 1998 requiring the fortification of all enriched grain products with folic acid . Globally, more than 50 countries have mandatory programs of wheat-flour fortification with folic acid, but flour fortification is not common in Europe .

Dietary folate inadequacy is common among adolescents in European nations, especially girls . Vitamin C helps your body absorb iron, a mineral that facilitates the transportation of oxygen through your blood stream and helps regulate cell growth. Vitamin C helps to keep your cells healthy and, as an antioxidant, may protect you from illness. The recommended daily intake is 75 milligrams of vitamin C for teen boys and 65 milligrams for teen girls. "Vitamin D is essential for good bone health and for most people sunlight is the most important source of vitamin D.

The time required to make sufficient vitamin D varies according to a number of environmental, physical and personal factors but is typically short and less than the amount of time needed for skin to redden and burn. Enjoying the sun safely, while taking care not to burn, can help to give the benefits of vitamin D without unduly raising the risk of skin cancer. Vitamin D supplements and specific foods can help to keep up sufficient levels of vitamin D, particularly in people at risk of deficiency. While there is no doubt that severe vitamin D deficiency leads to rickets in childhood and adolescence, the impact of less severe vitamin deficiency on health, especially non‐skeletal health effects, is less clear.

It has always been assumed that adolescents are not at risk of low vitamin D status; however, a number of recent studies have shown this not to be the case, especially during winter. In contrast, younger children seem to have a lower prevalence of low vitamin D status. The reasons for the high prevalence of vitamin D insufficiency during adolescence are unclear. Dietary supply of vitamin D, including vitamin D‐containing supplement use, is an important consideration in relation to improving vitamin D status during childhood and adolescence, especially during winter time. Unfortunately, much research effort is still needed to identify what the optimal dietary recommendation for vitamin D should be. According to Holick,54 approximately 30 min of skin exposure of the arms and face to sunlight can provide all the daily vitamin D needs of the body.

When sunlight exposure is limited, dietary intakes of vitamin D, if sufficient, can make a significant contribution to vitamin D status. Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism and is therefore necessary for bone health. The growth plates of bones continue to enlarge, but in the absence of adequate mineralization, weight-bearing limbs become bowed. Adding a variety of foods to a teen's diet can help her get what she needs, and supplementing with multivitamins may benefit some teens. It's important for teenagers to get all the necessary vitamins daily. However, several vitamins are particularly important for growth, development and sustained energy levels.

Fill your diet with a variety of vitamin-rich foods to get plenty of vitamins, as well as other nutrients, without having to worry about taking dietary supplements. Anyone who struggles to eat a healthy, varied, and balanced diet may benefit from taking supplements. For teenagers, it may be helpful to take iron, calcium, and vitamin D if you feel you are lacking these essential vitamins and minerals. Before you or your teenager start taking any new supplements it's a good idea to check with your GP or a pharmacist. The B vitamin, folate, is required as a coenzyme to mediate the transfer of one-carbon units.

Folate coenzymes act as acceptors and donors of one-carbon units in a variety of reactions critical to the endogenous synthesis and metabolism of nucleic acids and amino acids . Moreover, higher intakes of folate in adolescents have been linked to better academic achievement . Like other B vitamins, adolescent intake recommendations for folate were extrapolated from adult recommendations, using metabolic body weight and accounting for growth. The RDA for adolescents aged 14 to 18 years is 400 μg/day of dietary folate equivalents . Vitamin A is a fat-soluble vitamin that is essential for growth and development, normal vision, the expression of selected genes, immunity, and reproduction . Vitamin A deficiency in children and adolescents is a major public health problem worldwide, especially in less developed countries .

Even marginal or subclinical deficiencies in vitamin A may have adverse effects on bone growth and sexual maturation of adolescents . Because of its role in immunity, inadequate intake of this vitamin also increases risk for infectious diseases . Vitamin A promotes proper bone growth and tooth development, making it a vital nutrient for all children and adolescents. According to the Linus Pauling Institute, teens in industrialized countries tend to have low intakes of vitamin A, which is a necessary nutrient for adolescent development.

Teen boys should get 900 micrograms, or 3,000 international units, of vitamin A per day, while teen girls need 700 micrograms, or 2,333 international units of vitamin A daily. Dairy products provide vitamin B12, which is only found naturally in animal foods. This means dairy products are an especially important source of this nutrient for people who follow vegetarian diets and don't eat meat, fish or eggs.

It's important we get enough vitamin B12 as it's needed for our immune and nervous systems to work normally. Plus, dairy products are important sources of good-quality protein in vegetarian diets. Unlike most plant proteins, milk, cheese and yogurt provide all the essential amino acids that we need to build protein. These can't be made by our bodies so we have to get them from the food we eat.

The combo of little interest in nutrition, together with high nutrient needs, means the teen years are one of the main times in life when nutrients are most likely to be lacking in diets. Indeed, studies suggest intakes of some key vitamins and minerals are worryingly low, increasing the risk of deficiencies that may impact on health in the teen years but also later in life. Dairy products provide many of the nutrients that are often missing. Experts recommend waiting until your child is 4 years old to start giving a multivitamin supplement. In addition, keep multivitamins out of your child's reach, and make it clear that they are not candy. The product features 25 important vitamins and minerals such as plant-based calcium, magnesium, and vitamin D.

All of these nutrients are necessary for teens to build strong and healthy bones and muscles. An optimum nutritional intake during adolescence and young adulthood can help set the stage for lifelong health. Teenagers need to have sufficient vitamins and minerals to ensure healthy development during growth spurts, plus as they undergo significant physical and biochemical changes in their bodies. So the importance of obtaining the right nutrients in the diet is vital, just at a time when this may not be a top priority for some busy teenagers. This has all the vitamins and minerals essential for the healthy growth of the brain, immune system support, skin, and overall health of your teenage girls and boys.

We have considered numerous websites and hundreds of user reviews to curate this list of essential multivitamin supplements for teenagers. We have ensured that these products are safe and meet the necessary criteria. Each item on the list has a detailed description of the nutritional value, ingredients, and factors indicating the need for each of these supplements. You can choose one your child needs based on the their requirement and the doctor's advice.

Vitamin A is an over-the-counter vitamin that is naturally present in many foods. Vitamin A is important for normal vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys and other organs work properly. There are two different types of Vitamin A. The first, preformed vitamin A, is found in meat, poultry, fish and dairy products.

The second, provitamin A, is found in fruits, vegetables and other plant-based products. The most common type of provitamin A is beta-carotene which can be found in foods and dietary supplements. Dairy products provide several nutrients that can help support our brains, especially important when we're learning, taking exams and using a lot of brain power! Milk, cheese and yogurt are the main providers of iodine in the UK diet. Studies show 19% of teen boys and 28% of teen girls have very low intakes of iodine and so would benefit from more.

How Do You Calculate Cut And Fill Volume

Earthwork cost is one of the major cost items (approximately 25% of the construction costs) in road construction projects. The amount of earthwork volumes therefore earthwork cost, mostly depends on the geometry of the road vertical alignment. We can conclude that an optimized vertical alignment has a profound impact on earthwork costs. Proposed linear optimization model is supposed to be implemented with application of simplex method as the component of complex branch and bound approach.

The developed model has been implemented on the basis of practical example. After the optimization of vertical alignment, earthwork volumes have been calculated in the road design software with average end area volume calculation method. We also have provided numerical results which include earthwork volumes and cost improvements over preliminary design. This method involves drawing horizontal and vertical lines over your site plan to divide it into grid cells of equal size. You then include the existing elevation and proposed elevation for each corner of the grid cells, and work out the difference between the two, as this will be cut or fill depth for that spot. When you've done this for every corner you add them up, average them, and perform further calculations that will end up giving you a total number of cuts and fills.

The difference between these two numbers will show you if earth will need to be removed or brought onto site to complete the job. The grid method of calculation involves drawing a grid onto the plan for the earthwork project. For each node of the grid, determine the existing and proposed ground level and calculate the cut or fill required. Once the cut or fill depth is calculated, multiply the value by the area of the grid cell. Do this for each square of the grid, then add the volumes together to determine the total cut and fill volumes for the project. The grid method involves drawing a uniform grid onto a plan of the earthworks project, and taking off the existing and proposed ground levels at each node of the grid.

With these values the average depth of cut or fill required on each cell of the grid is calculated, and the volume for each cell is obtained by multiplying the depth by the cell area. By adding the volumes for each cell together the total cut and fill volumes for the project can be estimated. Reliable and accurate earthwork calculation is one of the most important components in road engineering that can influence the construction cost and road alignment choice. In this research, the method of ground penetrating radar was applied to detect the subsoil rock share in forest road construction.

The GPR data acquisition was carried out using a 250 MHz GPR antenna along 22 segments on the centerline and 12 meters across to the road project. The GPR data processing was done by performing different filters, such as background removal, migration, band pass filter, and horizontal and vertical smoothing on the GPR data. To investigate the capability of the GPR method used in this road construction project, we compared the GPR radargram and road profile after construction. The results indicated that the maximum penetration depth of the GPR waves produced by a 250 MHz GPR transmitter antenna, which were between 2 and 5 meters in fine area and rocky grounds, respectively.

Moreover, the capability of GPR to map large dimension roots and water content is presented in this work. So how do estimators calculate the volume between two surfaces? This can be a very complicated process since the amount that the elevation of the soil surface changes can vary considerably and irregularly across the site. The first surface is typically the existing site topography, while the second shows the post-construction site grades.

Post construction grades can result from excavation of existing soil, by the placement of additional soil, or by some combination of the two. The volumes required to place soil are typically designated as positive volume while those volumes resulting from excavation are treated as negative volumes. The resultant numbers can be added together to get a cut-to-fill balance for the site.

A well-designed site will result in a balanced cut to fill with the net volume of the two equaling zero. Depending on the nature of the site and its proposed earthwork, there are several options available for accurately estimating the resulting earthwork volumes. The largest share of emissions in road transport occurs in the use phase; hence, considering vehicles' behavior already in the early stages of the planning process is crucial. This study compares earthwork costs, fuel costs, and tank-to-wheel emissions of alternative road vertical alignments using a spline linear programming optimization method. The traditional minimal earthwork cost model is tailored and augmented with a fuel item to account for vehicle fuel costs.

Three options are considered, including an earthwork-based optimal road alignment, a balanced earthwork-and-fuel cost (EW-FC) optimal alignment, and a minimal fuel cost alignment. Calculations are done for a reference test heavy-duty vehicle assumed to operate at uniform speed. The results exhibited that, although leading to some increase in earthwork costs, a design for balanced EW-FC cost yields substantial fuel budget and related emissions savings. The cross-section method of calculation is a common method used with the 2-dimensional method of mapping. With this method, cross-sections of the existing and proposed land levels are measured at regular intervals across the site. The cut and fill area is determined for each cross-section, then adjacent cross-sections are compared and the averages of their cut and fill areas are multiplied by the distance between them.

This is done for each adjacent pair of sections, then the total volumes are added together to create the complete cut and fill volumes for the project. Determinations of alignments and station locations are major tasks in railway design, which jointly and fundamentally influence the construction and operation of the whole project. Therefore, this study focuses on modeling and optimization of passenger railway alignments and station locations simultaneously. A novel optimization model is formulated for maximizing net present value considering comprehensive costs and revenue from riders over the railway's design life. Specifically, the comprehensive cost includes construction and operation costs of alignments and stations. The railway ridership is quantified by combining travel time and trip coverage using a logit function.

Then, the railway revenue is estimated and combined with costs through an economic growth model to obtain the NPV. To solve this model, two customized and mutually exclusive methods, that is, the station-alignment-integration and alignment-station-integration methods, are developed based on a particle swarm algorithm. The SAI primarily searches for possible stations in the landscape and then generates alignments to connect adjacent stations.

The ASI directly yields the main alignment, on which potential stations are located by handling specific constraints. The model and methods are applied to an actual high-speed railway. Results show that both SAI- and ASI-generated railways have higher NPV values compared to the corresponding railway designed by experienced designers. Sensitivity analysis reveals that SAI is more flexible than ASI in solving actual cases.

With some changes in input parameters based on locally applicable design standards, the proposed methods are generally applicable to other cases or countries. The second outdated but still efficient way of calculating cut and fill ratios is the cross-section method. This requires a very accurate graph to be mapped out where the existing elevation is located across both a vertical and horizontal axis. From here, the proposed elevations for the new plans are to be overlaid and then a grid is created between the two spaces.

This then enables the surveyor to calculate each grid piece and its volume, then calculate the cut and fill ratios based on this work. Before drone technology for GPS mapping existed, there were two very manual ways of calculating cut and fill ratios for your job site. The first of which uses a grid method which calls for your construction plans to be laid out over a flat surface and then divided up equally into to set grid squares.

This then allows you to calculate and determine what cut and fill are required per each individual grid section. Following this, all grid sections can be added together for the overall volume required +/- 20%. The Triangulated Irregular Network and Digital Terrain Model Methods.The Triangulated Irregular Network method utilizes files created by AutoCAD (".tin" files) on topographic surfaces to determine volumes. This, in turn, allows for the creation of highly accurate Digital Terrain Models.

Given the huge number of calculations required, this is a process that can only be done on a computer. The DTMs allow for direct calculation between a surface and a fixed elevation or two such surfaces. DTMs can also be generated for different soil strata in an excavation, allowing for direct calculation of volumes for each soil type.

The slices are aligned perpendicular to a baseline running the full length of the earthwork area. This is usually the site's longest dimension to increase accuracy, but can also be aligned along a property or tract line, utility easement, right of way, roadway centerline, etc. The interval between the parallel slices can vary depending on the size of the site and the designed accuracy of the calculation. The volume of a massive 1,000-acre site development could be calculated with reasonable accuracy with intervals of 100 to 200 feet.

A smaller square building lot of fewer than 10 acres would not achieve reasonable accuracy with such a large interval as it would only utilize six slices. In general, the smaller the site, the smaller the required interval between slices. The cross section method involves plotting cross sections of the existing and proposed levels at regular intervals across the project site. For each of the cross sections, the cut area and the fill area is determined.

The volume between each pair of sections is estimated by multiplying the average cut or fill area of the two sections by the distance between them. Once these volumes have been calculated for each pair of sections the total cut and fill volumes are obtained by adding them all together. Formulas and methods for determining the volumes and areas of regular shapes and surfaces go back at least as far as ancient Greece. Pythagoras and other mathematicians determined those formulas that are still used to calculate the volumes of spheres and pyramids, as well as the areas of curve conic sections. But what was a matter of mystic philosophy to the Greeks is a matter of financial life or death for earthwork contractors.

Since there is an inherent error in any estimating earthwork calculation, the contractor must properly manage the resultant unknowns to ensure the success of the project. The triangular prism method starts by triangulating the existing terrain to create a continuous surface of connected triangles. Once both surfaces are complete, the triangulations are merged to create a third triangulation. Once merged, the cut and fill is calculated by taking the volumes of the generated triangles and adding them together.

Because of the excellent representation of both the existing and desired terrains, this method presents an excellent representation of volumes for cut and fill projects. The cross-section method of calculation is considerably more time-consuming than automatic methods of calculating volume, and the accuracy of the method depends on the distance set between sections. Closer sections result in greater accuracy but take longer to calculate, while further sections are less accurate but take less time to calculate. Once we create the EG and FG surfaces, we can proceed to create a volume TIN surface.

On this surface, we will select the EG as 'base surface' and the FG as 'comparison surface'. After this, we will have a volume surface in Civil 3D containing accurate cut and fill volumes. The software obtains these volumes by comparing the volume contained between the triangles of the EG and those of the FG. We then just need to open the volume dashboard and add our newly created volume surface.

The volume dashboard will give us the amount of cut and fill in the volume surface, as well as the net volume so that we know whether the project will have an excess of material or will have to import material . On top of these, one of the most popular tools amongst contractors is the Civil 3D cut and fill analysis. Estimating the earthworks volume often becomes one of the most challenging parts of any construction project. Traditionally, this estimate was a manual process, using cross-sections from topographical surveys. This method was very time-consuming and often led to substantial errors due to the human factor.

Airborne light detection and ranging surveying technology plays an important role in road design, and it is increasingly implemented in the design stage. This paper reviews the application of airborne LiDAR in road design and factors including items from the perceived usefulness of technology. The context of the future direction of LiDAR technology is highlighted in civil engineering road design, roadway inspection and as-built documentation. Therefore, designers and contractors prefer to place road in the areas that have soft terrain and minimum earthwork, excavation (Ghajar et al. 2012). The rock proportion of the subsoil directly impacts the cost of embankment in forest road, including the excavation depth and height (Contreras et al. 2012). There are many ways to estimate the earthwork volume and material as the most important target to optimize or manage horizontal and vertical alignment.

The Grid Method.The Grid Method is normally used to estimate volumes excavated from borrow pits . Like the Depth Area Method, the Grid Method utilizes thickness measurements over a given area. Each grid point is treated as the center of a square whose sides are equal to that of the grid interval . The surface slope within the grid square itself is accounted for and approximated by assigning surveyed or proposed elevations to each of the square's corner points. The square is treated as a column that goes directly down vertically through the proposed soil excavation where the four corners align with matching corners located on the proposed surface.

Measurements can then be taken to determine the depth of cut or fill at each corner . At Position Partners, we make calculating your cut and fill volumes and ratios easier and more cost-effective with our line of innovative drones and drone technology. This new extensive range of drone technology is aimed at making site surveying easier and more cost-effective. By increasing the survey accuracy and utilising the high quality, durable and innovative drone and software programs, large site areas can be surveyed in half the time.

By utilising remote flight technology, this cuts the number of boots on the ground required which is generally what increases surveying costs. A computational method that can be used to calculate cut and fill volumes more accurately than previous methods is proposed. The method is a simple one, and utilizes the primary concepts of the average-end-area formula, and provides additional constraints that should improve the accuracy of the results. The proposed technique applies certain limitations to each type of calculation that is made depending on the configuration (cut and/or fill) of the end areas of the two sections. These limitations involve the definition and location of a theoretical section having zero cross-sectional area.

Like the cross-section method of calculation, the grid method takes time to implement and is significantly more time-consuming than any automatic systems. Additionally, the accuracy of the grid method depends on the size of the grid cell. Larger cells take less time to calculate but are less accurate, while smaller cells are more accurate but take more time to calculate.

How Do You Calculate Fill Volume When building a road, it is critical to select a vertical alignment which ensures design and safety constraints. Finding such a vertical alignment is not necessarily a feasible problem, and the models describing it generally involve a large number of variables and constraints. This paper is dedicated to rapidly proving the feasibility or the infeasibility of a Mixed Integer Linear Program modeling the vertical alignment problem. To do so, we take advantage of the particular structure of the MILP, and we prove that only a few of the MILP's constraints determine the feasibility of the problem. In addition, we propose a method to build a feasible solution to the MILP that does not involve integer variables.

This enables time saving to proving the feasibility of the vertical alignment problem and to find a feasible vertical alignment, as emphasized by numerical results. It is on average 75 times faster to prove the feasibility and 10 times faster to build a feasible solution. After a successful flight, the stand-alone Agisoft Metashape software begins the process of photogrammetric processing of all digital images taken and generates 3D spatial data. This allows surveyors to gain an accurate description of the area and to begin to plan work. TBC helps you create projected surfaces along a vertical wall and perform earthwork analysis to detect and monitor the quantitative movement of the wall. Surveyors and construction engineers may also create cut/fill maps on 2.5D topographic surfaces to determine how much material needs to be cut or filled on a job site.
