IC shall ensure that the following parameters are analysed before constructing the wall on the extension of the culvert;

1.	Wind speeds on apron slab as the cell is 4m high
2.	Column/ footing weights
3.	How the foundations shall be attached to the apron slab and related affects
4.	Has the load of backfill around the wall foundations been considered
5.	Impact/ integrity during high floods at high velocity
6.	Deflections due to Wall foundations placed at mid span vs supports and its effects on the openings/ cells causing reduction in Area of the flow. 

Hydrology study and related Compaction tests are attached.
