ITEM: Providing, fabricating and placing in position reinforcement steel for tunnel RCC worksincluding cleaning, straightening, cutting, bending, hooking, lapping / welding joints wherever required, tying with 1.25 mm dia.soft annealed steel wire, including cost of all materials, labour, machinery, ventilation, lighting, drainage etc.,complete with initial lead upto 1 km and all lifts.

DATA:No welding of reinforcement bars is considered since the diameter of bars for tunnel RCC workswill be generally less than 32 mm.As concrete will be placed by pneumatic placer, the reinforcement bars have to be held regidlyin place to prevent displacement due to shooting effect of concrete. This requires about50 percent more binding wire compared to locations where concrete placement is by manuallabour.Quantity of binding wire for works other than tunnel : 9 kg / tonneQuantity of binding wire for reinforcement in tunnel ( 1.5 x 9 ) : 13.5 kg / tWastage of steel : 2.5 percentLabour requirement per tonne:In view of restricted head room between shuttering and excavation line placing reinforcementwill be slow compared to open area.Further bars in transverse direction are to be bent to matchthe profile of tunnel. This requires more labour for bending at fabrication yard and for placingbars in position in tunnel.Labour requirement per tonne:Cleaning and straightening : 2 Bar benders & 2 Heavy mazdoorsMarking, bending and stacking : 3 Bar benders & 6 Heavy mazdoorsPlacing in position and tying : 3 Bar benders & 6 Heavy mazdoorsChecking, correcting & misc. works : 1 Bar benders & 1 Heavy mazdoors
