## How do you read grading elevations?

For example, given a benchmark at 100.00 and a **grade elevation** at 101.43, the difference is -1.43, which indicates that the **elevation** is 1 foot and some odd inches above the benchmark. Multiply the decimal part of the difference times 12 to find the number of inches. For example, 0.43 x 12 = 5.16.

## How do you use grading stakes?

Pound **grade stakes** into the ground on each end of the area you need sloped. The **stake** at the top of the slope is called the hinge. The **stake** at the bottom of the slope is called the toe. Determine the desired **grade**—typically 1-2% (1/8″ per foot to 1/4″ per foot) is enough to provide enough runoff.

## What is a construction grade checker?

A **grade checker** works in the **construction** industry, typically on roadways, to set **grade** stakes meant to guide equipment operators on sloping highways and embankments. In this career, you set these **grade** stakes using hand tools, measuring instruments, and using specified ratios.

## What is a 6% grade?

Driving down a highway you may see a road sign that reads “**6**% **Grade**” or “Steep **Grade**.” The **grade** of the road is, essentially, its slope. A six percent slope means that the road elevation changes **6** feet for every 100 feet of horizontal distance (Figure 1.3). Figure 1.3. A road climbs at a gradient of **6** percent.

## How do you find the elevation between two points?

To **calculate** percent slope, divide the difference **between** the **elevations** of **two points** by the distance **between** them, then multiply the quotient by 100. The difference in **elevation between points** is called the rise. The distance **between** the **points** is called the run.

## How do you use stakes to level ground?

**How to Use** a Line **Level** to **Level Ground**

- Find a length of string and two wooden
**stakes**. - Tie one end of string to a wooden
**stake**and hammer it into the**ground**at the highest elevation in the area. - Hammer in the second
**stake**across the area you want leveled.

## What do Survey stakes mean?

**Stakes** with simple flags and basic identification: The **stakes** shown here all indicate an access route to be used for equipment and trucks to get to a proposed pipeline right of way. The “H310″ is the EQT name for the 30” OVC pipeline.

## What is the grade chart?

The 4.0 Scale

Percent Grade |
Letter Grade |
4.0 Scale |
---|---|---|

93-100 | A | 4.0 |

90-92 | A- | 3.7 |

87-89 | B+ | 3.3 |

83-86 | B | 3.0 |

## What is my grade percentage?

The **grade percentage** is calculated by dividing the earned points by the total points possible. The formula is: Points earned / Points Possible, then that **percentage** is compared to the given scale.

## How much does a grade checker make?

Construction Grade Checker Salary

Annual Salary | Weekly Pay | |
---|---|---|

Top Earners | $79,500 | $1,528 |

75th Percentile | $73,000 | $1,403 |

## What is the height of Levelling staff?

Levelling staffs are usually 2 to 5 m long, foldable or telescopic, and made of plastic-coated wood or aluminium. Self-reading levelling staffs are usually graduated in **metres**, decimetres, and centimetres. These graduations are upside-down so that you can read them with a telescope.

## How do you read staff leveling?

The **staff reading** is the **reading** on the **staff** at which the horizontal hair appears to cut the **staff**. A **staff reading** consists of 4 digits. The first digit represents the whole number of meters, the second digit represents decimeters, and the third, and fourth digits represent millimeters.

## How many types of leveling staff are there?

The following **three types** of self reading staffs are available: (a) Solid staff: It is a single piece of 3 m. (b) Folding staff: A staff of two pieces each of 2 m which can be folded one over the other. (c) Telescopic staff: A staff of 3 pieces with upper one solid and lower two hollow.
