Checklist : Plot Plan Drawing Information


Plot plan drawing is a critical document based on which all other engineering work is commenced. All the required incormation must be incorporated in Plot Plan Drawing. Following checklist shall be completed for the IFA and IFC issues of  a Plot Plan.

Information Required
