|
| (1) Use of Quieter Plant |
|
| (2) Use of Movable Barrier |
|
| (3) For Box Culvert and Bridge, piling, earthworks,
reinforcement fixing/concret operation and backfilling will not be carried
out at the same time. Thus, the maximum SWL of these activties will be used
for calculation. |
| (4) For Piling Work in Ho Chung Area, piling and reinforcement
fixing/concret operation will not be carried out at the same time. Thus, the
maximum SWL of these activties will be used for calculation. |
