Factory fabrication and assembly of rebar

① Based on reinforcing bar shop fabrication and field assembly work. ② Includes reinforcing bar splicing (lap splice or mechanical splice), spacer installation, and rebar lifting work. ③ Excludes material purchase and transportation costs (reinforcing bars, splice materials (couplers), spacers), on-site transportation costs, and shop drawing preparation costs. ④ Excludes special shop fabrication costs such as threading of reinforcing bars. ⑤ The application criteria by specification are as follows. Classification Type Type-Ⅰ a. Where reinforcing bars with diameter 13mm or less account for less than 50% of total reinforcing bar weight a. Where reinforcing bars with diameter 13mm or less account for 50% or more of total reinforcing bar weight b. Fabrication and assembly used in combination with structural steel Type-Ⅱ c. Structural facilities where reinforcing bars with diameter 13mm or less account for less than 50% of total reinforcing bar weight, but reinforcing bar fabrication and assembly work is complex (sewage treatment facilities, waste treatment facilities, etc.)

- When constructed in parallel with lifting equipment, apply by multiplying the following coefficients. Classification Standard Market Unit Price Labor Cost Ratio No lifting equipment used 1.00 1.00 Lifting equipment used 1.20 0.95 ※ Use of lifting equipment: Apply when site conditions (work at height / narrow rebar storage space, etc.) require continuous construction using a mobile crane.
