ITEM: Providing, fabricating and fixing in position permanent structural steel supportsas per details

including cost of all materials, machinery, labour, cutting, bending, welding, grinding, lighting,

ventilation, drainage and all other ancillary operations etc., complete with initial lead upto

1 km and all lifts.

DATA:Clear diameter of tunnel : 4.50 m

Assuming 300 mm thick concrete lining and about 25 cm extra excavation for fixing permanent

structural steel supports and further 20 cm pay line margin the over all width of tunnel for

excavation will be 6.00 m.

Permanent steel supports are generally provided in the form of quarter / half / full rib depending

on the condition of rock and mode of excavation and size of sections. For the purpose of rate

analysis quarter arch rib fabrication is considered.

Generally, the depth of rib will be considered at 25 mm per metre width of tunnel and the

spacing of ribs depends on the condition of strata to be supported. Average spacing of 5 times

the depth of rib ( generally 2 ribs per blast ) is considered for analysis.

For 6 m wide tunnel the depth of rib required will be 150 mm.

Further, to provide adiquate bearing for lagging sectoins wide flanged structural steel beams are

considered for tunnel supporting ribs.

ITEM: Providing, fabricating and placing in position reinforcement steel for tunnel RCC works

including 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 regidly

in place to prevent displacement due to shooting effect of concrete. This requires about

50 percent more binding wire compared to locations where concrete placement is by manual

labour.

Wastage of steel assumed at 2.5 percent.

Quantity of binding wire for works other than tunnel : 9 kg / tonne

Consider 1 tonne reinforcement steel for rate analysis.

Reinforcement steel ( 1 x 1.025 ) : 1.025 t

Binding wire ( 9 x 1.5 ) : 13.5 kg


No machinery is required.


In view of restricted head room between shuttering and excavation line placing reinforcement

will be slow compared to open area.Further bars in transverse direction are to be bent to match

the profile of tunnel. This requires more labour for bending at fabrication yard and for placing

bars in position in tunnel.

Cleaning and straightening : 2 Bar benders & 2 Heavy mazdoors

Marking, bending and stacking : 2 Bar benders & 4 Heavy mazdoors

Placing in position and tying : 4 Bar benders & 4 Heavy mazdoors

Checking, correcting & misc. works : 1 Bar bender & 2 Heavy mazdoors

4. Re-handling lead for materials:As reinforcement steel is stored outside tunnel and is to be conveyed inside tunnel after

fabrication at fabrication yard re-handling lead of 1 km is considered.
