Determine the following: (show complete solution with appropriate explanation if necessary, then highlight final answer)

1) For ACITIVITY-CLEARING AND GRUBBING (Removal of trees and foliage undergrowth), determine the total duration

20 For ACTIVITY-CLEARING AND GRUBBING (Removal of trees and foliage undergrowth), determine the total cost

3) For ACTIVITY-EXCAVATION, determine the total duration

**EXPERT ANSWER**

Area = 1 hectare

No of trees -= 358

No of trees to be cut = 300

Work done from March 4 2021 to April 2 2021 excluding Saturday, Sunday. This becomes 23 days period.

No of labourers employed = 15 , 340/day.

So, total labour cost for 23 days= 15*340 * 23 = 117300

Chain Saw cost per 2 persons = 18000 * 2 = 36000

Chain saw cost for 300 trees = 3600*300 = 10800000.

So, total cost would be = 117300 + 10800000 = 10917300.

The amount of work done ( the area covered by one person ) is not clearly mentioned and so it is considered that all the labourers are paid 340 for all the 23 days.
