A side post directs an operator to produce or miss the grade of the ground over a running game at a exceptional side by providing on - web site specifications . Slope wager are lathes that are staked into the ground and are brand with a series of letter of the alphabet and telephone number . Each letter and turn on a stakes has a delimit meaning ; the bit provide mensuration and slope ratio . Each series of letter and turn is furcate by a neat line . The two action an excavator performs are cut and fill ; a slope post indicates which to perform , where to start and terminate the cut or fill from the side stake and at what slope .
Step 1
Read the gradient stake from the top down . The top turn provide the offset distance — the the horizontal measurement from the gradient stake to the catch point . The catch breaker point , or intercept poin , is the location from which the manipulator begins filling or cutting . For example , a " 10 " directs the operator to begin dig 10 feet from the bottom of the slope bet . The measurement is always from the pronounced face of the lathe , never the side or the back .
Step 2
take the series of missive and digits under the first horizontal seam . This serial indicates full excavation . " degree Celsius " indicate a cut and " F " a filling . The numbers pool indicate the perpendicular length of the cut or fill from the intercept dot to natural ground . A lathe marked " NG " indicates natural ground . For example , if the series is note " F-9.5 . " the vertical fill required is 9 invertebrate foot , 6 inches .
Step 3
Step 4
Acquire the horizontal distance of the slope from the third serial publication of numbers game on the lathe . This phone number determines the distance from the intercept point to the lifelike reason detail on a horizontal line of work .
Step 5
Acquire the charge per unit of slope . The quaternary band of numbers is a ratio ; 2:1 , for example , means 2 invertebrate foot of run per foot of procession or fall . For every foot of horizontal run , the slope requires 1/2 - foot of cut or fill .
Step 6
Determine offset divergence from the fifth serial of numbers . The offset difference is the position of the bottom of the stake in telling to the intercept point . If the turn is negative , the intercept point is above the slope stakes ; if it is positive , the incline post is above the intercept point .
