Client: Engro Polymer and Chemicals Limited (EPCL)

Date: 2023-2024


3D Engineering Surveys Ltd delivered the first fully intelligent 3D model with complete generation of as-built 2D plant documentation ever completed within Pakistan on behalf of EPCL at their EDC-VCM plant in Karachi, Pakistan, to enable accurate design for future upgrades at the facility.


Scope of Work & Deliverables.

Installation of permanent primary control network—Using the EPCL plant grid datum, 3DES traversed and installed a permanent primary control network for all. A complete control network report with station descriptions was issued.
