Factory fabrication and assembly of rebar

① Based on factory fabrication and on-site assembly work of rebar. ② Includes rebar splicing (lap splice or mechanical splice), spacer installation, and rebar lifting work. ③ Excludes material purchase and transportation costs (rebar, splice materials (couplers), spacers), on-site handling costs, and shop drawing preparation costs. ④ Excludes special factory processing costs such as rebar threading. ⑤ For applicable types by specification, refer to the following. Category Type a. Civil engineering structures with typical rebar fabrication and assembly work (semi-gravity retaining walls, L-shaped retaining walls, bridge slabs, mat foundations, sluice gates, etc.) Type-Ⅰ b. Cases where rebar fabrication and assembly are repeated at a specific location (beam fabrication, welded wire mesh, etc.) a. Civil engineering structures with complex rebar fabrication and assembly work (rahmen bridges, abutments, box culverts, underpasses, counterfort retaining walls, sewage treatment facilities, waste treatment plants, etc.) Type-Ⅱ b. Cases where a small quantity of rebar is used relative to concrete (side ditches/open channels, gravity retaining walls, monolithic median barriers, etc.) c. In Type-Ⅰ facilities, where rebars with a diameter of 13mm or less account for 50% or more of the total rebar weight a. Civil engineering structures with very complex rebar fabrication and assembly work (piers, old-style abutments, etc.) Type-Ⅲ b. Cases in special structural facilities where rebar diameter exceeds 35mm and stand-alone manual installation is difficult (plant structures such as nuclear power plants)

- When work is carried out in combination with lifting equipment, apply by multiplying the following factors. Category Standard market unit price Labor cost ratio Without lifting equipment 1.00 1.00 With lifting equipment 1.17 0.96 ※ Use of lifting equipment: apply where, due to site conditions (work at height / narrow rebar storage space, etc.), construction using a mobile crane is continuously required.
