However, when the total lead is less than km., it will not be ignoredbut paidfor separately in successive stages of 50meterssubject to the condition that the rate worked on thisbasis does not exceed the rate for initial lead of 1 km. by mechanical/animal labour shall be reckoned in units of50 meters or part ;alldistances shall be measured over the shortest route. Route other than shortest practicalroute may be considered in cases of unavoidable circumstances and approved by Engineer-in-chargealong With reasons in Lift:The vertical distance for removal with reference to the ground level. The excavation up to depth below the ground level and depositing the excavated materials upto above theground level are included in the rate ofearth work. Lifts inherent in the lead due to ground slope shall notbe paid ANTIQUITIESAND USEFUL of archaeological interest such as relics of antiquity, coins, fossils or other articles of-valueobtained in excavationshallbe delivered to the Engineer-in-Charge and shall be the property oflocal body (Municipal Corporation, Municipal Council, Nagar Panchayat).

The contractor has to take written permission aboutproperplace of disposal of earth before the earth is disposed off, from CLEARANCEJ ungle clearance shall comprise uprooting of rank vegetation, grass, brushwood, shrubs, stumps, treesand saplings of girth upto 30 cm measured at a height of onemeterabove the ground level. Where onlyclearance of grass is involved it shall be measured and paid for of VegetationsThe roots of trees and saplings shall be removed to a depth of 60 cm below ground level or 30 cm belowformation level or 15 cm below sub-grade level, whichever is lower.

9 All holes or hollowsformed due toremoval of roots shall be filled up with earth rammed andleveled.
