Rate for jungle clearance work is neither incorporated in PWR SOR nor skeleton for the same work is mentioned in PWD Skeleton. Besides above labour constants/output of labourer for jungle clearance work is not given in the books "Estimating and Costing in Civil Engineering" written by B.N. Dutta, "Civil Engineering Estimating & Costing" written by V.N. Vazirani & S,C. Chandola and "Indian Practical Civil Engineers' Hanbook" written by P.N. Khanna. However, labour constant for 'clear site of all rubbish, cut down shrubs, undergroth and small trees not exceeding 600 mm girth, grub up roots and burn or remove from site' is recommended as 0.05 per sqm in a day on serial no. 30 of the table given under chapter 'Labour Output Constants for Building Work' of the book "Practical Information for Qauntity Surveyors" written by P.T. Jogelkar. Hence, Output of Mazdoor/beldar for the above work = 1/0.05 = 20 sq m per day. Alongwith above a specific rate for jungle clearance is given in ID SOR as Rs. 57 per %sqm.

Output of labourer for the above work on the basis of ID SOR, assuming 10% contractor's profit & 1% for Sundries, T&P, etc.and prevailing labour rate as Rs.84 per manday =84/1.111 x100/57 = 132.6 sqm/day

On the basis of above facts and past experience & practically feasible conditions, the output of a labourer for jungle clearance work is adopted as

Hence, rate for Jungle clearance including costs of all materials, labour, T&P, etc. complete for the completion of work = 125/130
