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.

how do you calculate cut and fill volume - We can conclude that an optimized vertical alignment has a profound impact on earthwork costs

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.

how do you calculate cut and fill volume - After the optimization of vertical alignment

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.

how do you calculate cut and fill volume - We also have provided numerical results which include earthwork volumes and cost improvements over preliminary design

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.

how do you calculate cut and fill volume - This method involves drawing horizontal and vertical lines over your site plan to divide it into grid cells of equal size

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.

how do you calculate cut and fill volume - You then include the existing elevation and proposed elevation for each corner of the grid cells

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.

how do you calculate cut and fill volume - When youve done this for every corner you add them up

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.

how do you calculate cut and fill volume - 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 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.

how do you calculate cut and fill volume - The grid method of calculation involves drawing a grid onto the plan for the earthwork project

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.

how do you calculate cut and fill volume - For each node of the grid

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.

how do you calculate cut and fill volume - Once the cut or fill depth is calculated

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.

how do you calculate cut and fill volume - Do this for each square of the grid

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.

how do you calculate cut and fill volume - The grid method involves drawing a uniform grid onto a plan of the earthworks project

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.

how do you calculate cut and fill volume - With these values the average depth of cut or fill required on each cell of the grid is calculated

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.

how do you calculate cut and fill volume - By adding the volumes for each cell together the total cut and fill volumes for the project can be estimated

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.

how do you calculate cut and fill volume - 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

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.

how do you calculate cut and fill volume - In this research

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.

how do you calculate cut and fill volume - 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

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.

how do you calculate cut and fill volume - The GPR data processing was done by performing different filters

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.

how do you calculate cut and fill volume - To investigate the capability of the GPR method used in this road construction project

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.

how do you calculate cut and fill volume - The results indicated that the maximum penetration depth of the GPR waves produced by a 250 MHz GPR transmitter antenna

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.

how do you calculate cut and fill volume - Moreover

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.

how do you calculate cut and fill volume - So how do estimators calculate the volume between two surfaces

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.

how do you calculate cut and fill volume - 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

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 cut and fill volume - The first surface is typically the existing site topography

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.

How Do You Calculate Fill Volume

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.

how do you calculate cut and fill volume - The volumes required to place soil are typically designated as positive volume while those volumes resulting from excavation are treated as negative volumes

This delta time is reported to the driver, and must remain positive throughout the VSC period else the driver will be penalised.GreenNormal racing conditions apply.

In the early days of Grand Prix racing, a driver would be allowed to continue a race in their teammate's car should theirs develop a problem – in the modern era, cars are so carefully fitted to drivers that this has become impossible. In recent years, the emphasis has been on changing refuelling and tyre change regulations. Since the 2010 season, refuelling – which was reintroduced in 1994 – has not been allowed, to encourage less tactical racing following safety concerns. The rule requiring both compounds of tyre to be used during the race was introduced in 2007, again to encourage racing on the track.

The safety car is another relatively recent innovation that reduced the need to deploy the red flag, allowing races to be completed on time for a growing international live television audience. On the track, the McLaren and Williams teams dominated the 1980s and 1990s, with Brabham also being competitive during the early part of the 1980s, winning two Drivers' Championships with Nelson Piquet. The rivalry between racers Ayrton Senna and Alain Prost became F1's central focus during 1988 and continued until Prost retired at the end of 1993. Senna died at the 1994 San Marino Grand Prix after crashing into a wall on the exit of the notorious curve Tamburello. The FIA worked to improve the sport's safety standards since that weekend, during which Roland Ratzenberger also lost his life in an accident during Saturday qualifying. Since 1994, three track marshals have lost their lives, one at the 2000 Italian Grand Prix, the second at the 2001 Australian Grand Prix and the third at the 2013 Canadian Grand Prix.

Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile , motorsport's world governing body. The "formula" in the name alludes to a series of rules established by the FIA to which all participants and vehicles are required to conform. Each year, the F1 World Championship season is held, consisting of a series of races, known as Grands Prix, held usually on purpose-built circuits, and in a few cases on closed city streets. Constructors are awarded points based on the finishing position of each of their two drivers at each Grand Prix, and the constructor who accumulates the most points over each championship is crowned that year's World Constructors' Champion. As of the 2021 Abu Dhabi Grand Prix, there have been 171 Formula One constructors who have raced at least one of the 1,057 FIA World Championship races since the first such event, the 1950 British Grand Prix.

This period featured teams managed by road-car manufacturers Alfa Romeo, Ferrari, Mercedes-Benz, and Maserati. They were front-engined, with narrow tyres and 1.5-litre supercharged or 4.5-litre naturally aspirated engines. The 1952 and 1953 World Championships were run to Formula Two regulations, for smaller, less powerful cars, due to concerns over the lack of Formula One cars available.

formula 1 racers and teams - A green flag is also shown at the start of a session

When a new Formula One formula for engines limited to 2.5 litres was reinstated to the world championship for 1954, Mercedes-Benz introduced the advanced W196. This featured innovations such as desmodromic valves and fuel injection, as well as enclosed streamlined bodywork. Mercedes drivers won the championship for two years, before the team withdrew from all motorsport in the wake of the 1955 Le Mans disaster. The current qualifying system was adopted in the 2006 season.

formula 1 racers and teams - Double waved yellows inform drivers that they must slow down as marshals are working on or near to the track and drivers should be prepared to stop

Known as "knock-out" qualifying, it is split into three periods, known as Q1, Q2, and Q3. Drivers are allowed as many laps as they wish within each period. After each period, all times are reset, and only a driver's fastest lap in that period counts.

formula 1 racers and teams - Can be seen

Any timed lap started before the end of that period may be completed, and will count toward that driver's placement. The number of cars eliminated in each period is dependent on the total number of cars entered into the championship. Currently, with 20 cars, Q1 runs for 18 minutes, and eliminates the slowest five drivers. During this period, any driver whose best lap takes longer than 107% of the fastest time in Q1 will not be allowed to start the race without permission from the stewards. Otherwise, all drivers proceed to the race albeit in the worst starting positions. In Q2, the 15 remaining drivers have 15 minutes to set one of the ten fastest times and proceed to the next period.

formula 1 racers and teams - If the flag is missed 3 times

Finally, Q3 lasts 12 minutes and sees the remaining ten drivers decide the first ten grid positions. At the beginning of the 2016 Formula 1 season, the FIA introduced a new qualifying format, whereby drivers were knocked out every 90 seconds after a certain amount of time had passed in each session. The aim was to mix up grid positions for the race, but due to unpopularity the FIA reverted to the above qualifying format for the Chinese GP, after running the format for only two races. Italian driver Andrea de Cesaris holds the record for the most races without a win, as well as the most retirements of any driver .

Fast but very accident prone in his early years – he was nicknamed "de Crasheris' after 19 shunts during his debut season with McLaren in 1981 – de Cesaris matured into a steady pair of hands in the midfield over an F1 career that spanned 15 seasons. But even when he wasn't crashing out, de Cesaris still failed to see the chequered flag in more than 70% of his F1 starts at a time when cars were notoriously unreliable. His worst period of unreliability came in a record 22-race streak from the end of 1986 to the early part of 1988, when he failed to finish any races. Despite retiring from every race during the 1987 season, de Cesaris did stand on the podium in Belgium - he was classified third despite running out of fuel on the last lap. During this period, the championship rules were changed frequently by the FIA with the intention of improving the on-track action and cutting costs.

Team orders, legal since the championship started during 1950, were banned during 2002, after several incidents, in which teams openly manipulated race results, generating negative publicity, most famously by Ferrari at the 2002 Austrian Grand Prix. Other changes included the qualifying format, the points scoring system, the technical regulations, and rules specifying how long engines and tyres must last. Bridgestone then went on to sign a contract on 20 December 2007 that officially made them the exclusive tyre supplier for the next three seasons. Although the UK's Stirling Moss was able to compete regularly, he was never able to win the world championship and has been described by The Independent as "The greatest driver to never win the world championship". In a seven-year span between 1955 and 1961, Moss finished as championship runner-up four times and in third place the other three times.

Fangio, however, achieved the record of winning 24 of the 52 races he entered - a record that holds to this day. National championships existed in South Africa and the UK in the 1960s and 1970s. Non-championship Formula One events were held by promoters for many years, but due to the increasing cost of competition, the last of these occurred in 1983. Chris Amon holds the record for most laps led and most pole positions without a win. The driver from New Zealand scored 11 podiums from his 96 starts in the 1960s and 1970s, but terrible luck and poor reliability prevented him from claiming an elusive victory.

formula 1 racers and teams - The main changes have revolved around what is allowed at pit stops

Amon led seven races during his career with Ferrari, March and Matra, but suffered a series of heart breaking retirements within sight of the chequered flag. Despite never standing on the top step of the podium at a championship race, Amon did score eight victories in non-championship F1 races and also won the Daytona 24 Hours and Le Mans 24 Hours. His controversial victory at Le Mans in 1966, which was shared with countryman Bruce McLaren, was dramatised in the hit 2019 film, Ford vs Ferrari. However, without drivers, the cars could not race so they are just as important to the sport and can also be considered equipment. The racing teams that prepare the cars, service them in the pits in race, and manage the operation of each pair of drivers they have are also an essential part of the premier motorsport. Finally, the tracks that the races are run on are all different and unique which helps create excitement and popularity as well as a diversity of tracks across the globe.

formula 1 racers and teams - In the early days of Grand Prix racing

All of these elements are needed to run a Formula 1 race each week of the season. As of 2019, each team may have no more than two cars available for use at any time. Each driver may use no more than four engines during a championship season unless they drive for more than one team.

formula 1 racers and teams - In recent years

If more engines are used, they drop ten places on the starting grid of the event at which an additional engine is used. The only exception is where the engine is provided by a manufacturer or supplier taking part in its first championship season, in which case up to five may be used by a driver. Each driver may use no more than one gearbox for six consecutive events; every unscheduled gearbox change requires the driver to drop five places on the grid unless they failed to finish the previous race due to reasons beyond the team's control. This approach lasted until the end of 2002 before the rules were changed again because the teams were not running in the early part of the session to take advantage of better track conditions later on.

formula 1 racers and teams - Since the 2010 season

Michael Schumacher, the living legend and the greatest Formula 1 driver, is the winner of 7 world championships for the year 1994, 1995, 2000, 2001, 2002, 2003 and 2004. Other than winning maximum championships, his other records include fastest laps and maximum number of races won during a single season. Schumacher, is the only F1 driver to have made history by finishing in the top three rank in every race of a season. Formula One official website quotes him as "statistically the greatest driver the sport has ever seen". The first seasons were run using pre-war cars like Alfa's 158. They were front engined, with narrow-treaded tyres and 1.5 litre supercharged or 4.5 litre normally aspirated engines.

formula 1 racers and teams - The rule requiring both compounds of tyre to be used during the race was introduced in 2007

When Formula One regulations returned in 1954 engines were limited to 2.5 litres. Mercedes Benz made major developments until they withdrew from all motor sports in the aftermath of the 1955 disaster at Le Mans. In the late 1950s Cooper introduced a rear-engined car and by 1961 all manufacturers were running them. As an added incentive for the teams, a constructors' championship was introduced in 1958. A typical circuit features a stretch of straight road on which the starting grid is situated.

formula 1 racers and teams - The safety car is another relatively recent innovation that reduced the need to deploy the red flag

The layout of the rest of the circuit varies widely, although in most cases the circuit runs in a clockwise direction. Those few circuits that run anticlockwise (and therefore have predominantly left-handed corners) can cause drivers neck problems due to the enormous lateral forces generated by F1 cars pulling their heads in the opposite direction to normal. A single race requires hotel rooms to accommodate at least 5,000 visitors. On the basis of this regulation, despite the fact that most current teams are based in the UK, this country is officially represented in Formula One only by teams holding a racing licence issued by the British National Sporting Authority. Teams take the nationality of their parent National Automobile Club that issued their licence for the period of validity of that licence and the change of the nationality is allowed. Benetton is the only team to have achieved victories while racing under two different nationalities.

formula 1 racers and teams - On the track

Before the arrival of sponsorship liveries in 1968 team's nationality determined the colour of a car entered by the team; thus, Italian teams' cars were rosso corsa red, French were bleu de France blue, and British were British racing green. Nick Heidfeld holds the record for most podium finishes in Formula 1 without a win. The German driver stood on the podium 13 times from his 183 starts, but never on the top step. Heidfeld spent much of this career fighting for points in the midfield with Sauber, though he did enjoy several competitive seasons when the team was partnered with BMW in 2007 and 2008. The closest Heidfeld came to tasting victory was at the 2007 Canadian Grand Prix, where he finished four seconds behind race winner Lewis Hamilton.

formula 1 racers and teams - The rivalry between racers Ayrton Senna and Alain Prost became F1

Italian racer Luca Badoer holds the record for the most F1 starts and most racing laps completed without scoring a point. Badoer made most of his F1 starts with Italian backmarker teams Scuderia Italia, Minardi and Forti in the mid 1990s, but is probably best remembered for his less than stellar comeback with Ferrari in 2009. A long-time test driver for Ferrari, Badoer was drafted in to replace Felipe Massa after the Brazilian suffered head injuries in a freak crash at the Hungaroring. But it wasn't to be a positive return for Badoer, who had last competed in Formula 1 ten years earlier and was hopelessly off the pace. After qualifying and finishing dead last in both the European and Belgian Grands Prix, Badoer was replaced by Giancarlo Fisichella for the remainder of the season. Formula 1 is considered the premier motor sport across the globe and it is unique compared to all the others in a few ways.

First, the open wheel concept of the cars along with the wings at the front and back give the cars a certain flair and look that is not seen often in other racing events, especially in the US. The engines are also unlike any across the racing sphere having supercharged elements that make the cars handle better and drive faster than their peers. Combining these two main elements along with the uniqueness of every track across the world they race in, Formula 1 has a very particular brand in racing that attracts many worldwide. An era of British dominance was ushered in by Mike Hawthorn's championship win in 1958, although Stirling Moss had been at the forefront of the sport without ever securing the world title.

Between Jim Clark, Jackie Stewart, John Surtees, Jack Brabham, Graham Hill, and Denny Hulme, British and Commonwealth drivers won nine drivers' championships and British teams won ten constructors' titles between 1962 and 1973. In the earlier history of Formula One, many races took place outside the World Championship, and local championships run to Formula One regulations also occurred. These events often took place on circuits that were not always suitable for the World Championship, and featured local cars and drivers as well as those competing in the championship.

Grids were generally limited to 26 cars – if the race had more entries, qualification would also decide which drivers would start the race. During the early 1990s, the number of entries was so high that the worst-performing teams had to enter a pre-qualifying session, with the fastest cars allowed through to the main qualifying session. The qualifying format began to change in the early 2000s, with the FIA experimenting with limiting the number of laps, determining the aggregate time over two sessions, and allowing each driver only one qualifying lap. World champion John Surtees drove for the team in 1967 and scored a memorable victory at the Italian Grand Prix - winning with the new RA300 in its first race. The team withdrew from motor racing after the 1968 season, to concentrate their energies on developing new road cars, having cemented the Honda name in the motorsport hall of fame.

A wide variety of technologies – including active suspension and ground effect aerodynamics – are banned under the current regulations. Despite this the current generation of cars can reach speeds in excess of 350 km/h at some circuits. The highest straight line speed recorded during a Grand Prix was 372.6 km/h (231.5 mph), set by Juan Pablo Montoya during the 2005 Italian Grand Prix.

A BAR-Honda Formula One car, running with minimum downforce on a runway in the Mojave Desert achieved a top speed of 415 km/h in 2006. According to Honda, the car fully met the FIA Formula One regulations. Downforce of 2.5 times the car's weight can be achieved at full speed. The downforce means that the cars can achieve a lateral force with a magnitude of up to 3.5 times that of the force of gravity (3.5g) in cornering. Consequently, the driver's head is pulled sideways with a force equivalent to the weight of 20 kg in corners. Such high lateral forces are enough to make breathing difficult and the drivers need supreme concentration and fitness to maintain their focus for the one to two hours that it takes to complete the race.

A high-performance road car like the Enzo Ferrari only achieves around 1g. American open-wheel car racing has also contributed to the Formula One grid. CART champions Mario Andretti and Jacques Villeneuve became F1 World Champions, while Juan Pablo Montoya won seven races in F1. Other CART champions, like Michael Andretti and Alessandro Zanardi won no races in F1. Other drivers have taken different paths to F1; Damon Hill raced motorbikes, and Michael Schumacher raced in sports cars, albeit after climbing through the junior single-seater ranks. Former F1 driver Paul di Resta raced in DTM until he was signed with Force India in 2011.

formula 1 racers and teams - Constructors are awarded points based on the finishing position of each of their two drivers at each Grand Prix

If less than 75% of the race laps are completed by the winner, then only half of the points listed in the table are awarded to the drivers and constructors. This has happened on only five occasions in the history of the championship, and it had a notable influence on the final standing of the 1984 season. The last occurrence was at the 2021 Belgian Grand Prix when the race was called off after just 3 laps behind a safety car due to torrential rain.

Under normal circumstances, the winner of the race is the first driver to cross the finish line having completed a set number of laps. Each car is allocated one set of the softest tyres for use in Q3. The cars that qualify for Q3 must return them after Q3; the cars that do not qualify for Q3 can use them during the race.
