Durame Site 202 Batu Site 251 Gimbichu Site 208 Arsi Negele Site 277 Waka Site 213 Meki Site 290
RFI No. Date Rec'd Item No. Question TT Response Response Date Follow‐up
1 An electric manhole is shown to be placed ri ght in front of OPD Block (EL ‐ 005). This manhole, at the proposed location, is placed at the center of the compound, car parking and junction of the Health Center.
This will cause inconvenience to the Health Center. We request your approval to shift the manhole location at around 7m towards the guard house (please refer to the attached sketch showing our proposal).
Proposal is acceptable. This has no cost implications.

2 The top slab of the Holding Tank will be 1.40m beIow the NGL. Since the pit created by this is too deep, the Holding Tank needs to be backfilled by soil. This will cause load on the top slab. Will the Holding Tank structural elements withstand the additional load? Please clarify. Please note that the bottom slab has been constructed and masonry wall is in progress.
Keep elevations and use attached drawing.
This has no cost implications.
