Over time, brownfield plants drift from original EPC documentation due to MOC changes and undocumented modifications.
These gaps between design intent and site reality can cause rework, shutdown delays, safety risks, and audit challenges. SixD’s As-Built Survey uses high-density 3D laser scanning, site verification, and intelligent modelling to capture accurate as-is conditions. The result is Master PFDs, UFDs, and P&IDs that serve as a controlled engineering reference, eliminating assumptions and reducing lifecycle risk.
