From: Assessment of Delay Factors for Structural Frameworks in Free-form Tall Buildings Using the FMEA
Consideration | Delay factor | |
---|---|---|
A. Plane | A-F1 | Increased rebar installation work |
A-F2 | Construction joint work increase | |
A-F3 | Increased production and installation/disassembly of nonstandard formwork | |
A-F4 | Increase in ACS installation/dismantling time | |
A-F5 | Increase in production time of nonstandard formwork | |
A-F6 | Increased worker transit time due to split L/C zoning | |
A-F7 | Lack of a preparatory plan | |
A-F8 | Lack of worker skills | |
A-F9 | Lack of understanding by the field manager of the design drawings | |
B. Elevation | B-F1 | T/C and L/C increase, additional material installation work |
B-F2 | Tilt adjustment operation when the ACS climbs | |
B-F3 | Tilted reinforcement work | |
B-F4 | Formwork work corresponding to the slope of the elevation | |
B-F5 | Lack of worker skills | |
B-F6 | Lack of understanding by the field manager of the design drawings | |
C. Floor height | C-F1 | Additional formwork installation for vertical member construction |
C-F2 | Additional scaffold installation work when the ACS is applied | |
C-F3 | Install additional form after ACS climbing | |
C-F4 | Lack of a preparatory plan | |
C-F5 | Lack of worker skills | |
D. Structural | D-F1 | Reinforcement work with high difficulty |
D-F2 | Selection error of construction order of special structure and slab layer | |
D-F3 | Additional temporary material installation work | |
D-F4 | Additional joining operations for additional structures | |
D-F5 | Lack of a preparatory plan | |
D-F6 | Lack of worker skills | |
D-F7 | Lack of understanding by the field manager of the design drawings |
