8-May-14 1 The electrical line from MDB at OPD Block to SDB at Administration Block (EL - 007) requires chiseling of the grade beam of Administration Block which might affect the stability of the block. (Please find attached the picture showing the pve pipe at entrance to Administration Block). We request your approval to use surface mounted weather proof u PVC pipes as shown on Meki engineer's answer to RFI 00003.
Proposed solution is acceptable. Construct above grade electrical installation per attached details on EX-502.

However, it is not clear up to where the telephone lines are to be installed by Subcontractor since it is not shown in the Site Electrical Plan.
The verandah floor finish is to remain and so is the telephone line to be installed undemeath the floor? Please clarify.
Pull the telephone line overhead per the attached revised sheet Administration/ANC Block Electrical Plan EL-003.
