PART A - CIVIL WORK

Dismantling the R.C.C. Work 1:2:4 and sorting out the materials such as steel etc. as directed and stacking them within the specified lead as directed etc. complete.

Dismantling of existing B.T. Surface (Flexible Pavement) to a depth of 50 mm manually, including loading of dismantled material to transport vehicle at site, excluding lead charges.

Excavation for roadway in soft rock, including dressing section to the required grade, camber and side slopes and conveying the excavated materials with all lifts up to a lead of 50 m and spreading or stacking as directed.

Trasportation of excavated material obtained from excavation including loading, unloading and stacking upto 5km extra, complete. 5km=5000m, Lead=252.22 for per meter=(252.22/5000)=0.05/meter. Total lead= (5000-50)=4950 meter(4950*0.05)=247.50
