Check list for approval of ESP (Engineering Scale Plans) issued by Engineering department…
Engineering Scale Plan is the basis for yard layout of a station and Signalling plan. Utmost care has to taken by the divisions while preparing and scrutinizing the ESP’s.
It has been observed that the Engineering Scale Plans are not being checked thoroughly by the divisions comparing with the last approved ESP, SlP and with site conditions in case of discrepancy between approved ESP and SIP before forwarding the plans for the approval of Headquarters. This is leading to consumption of lot of time at Headquarters tor getting attended the observations noted during the scrutinization of ESP. lf the religious scrutiny is done at divisional level lot of time can be saved both at divisional and headquarters level.
For the guidance and follow up, the list of items to be checked during the approval of ESP are described below…
