| Main Contractor | DAELIM Industrial Co. |
| Original Design | Bored Pile (1000mm up to 60m depth) |
|---|---|
| Alternative | Steel Tubular Pile Driving (1000mm up to 60m depth) |
| Outcome | Shorten Schedule (4.5month) |
| Original Design | Sheet pile |
|---|---|
| Alternative | Steel Tublar Pile Driving (1200mm) width LT Clutch for sheet pile |
| Outcome | Shorten Schedule Improve safety & constructability |
Controlled Modulus Column
| Conventional Piling | CMC | Advantage |
|---|---|---|
| Require concrete pile cap | Could be granular mattress (w/geogrid) |
Cost saving by eliminating “pile cap concrete, piling work” Mostly effective for large diameter tank farm |
| Pile : Reinforced Concrete | Pile : Plain Cement Pile | |
| Deeper depth to get bearing capacity | Terminate at shallower depth, subject to settlement evaluation |
