1. Project Title
  • As-Built P&ID development and 3D Model
  1. Project Summary
  • The project involved the progressive development of a complete suite of site P&IDs and a coordinated 3D as-built model for an operational manufacturing facility.
  • The work covered the production hall, mixing rooms, tank farms, on/off loading bays, boiler house and the wider site infrastructure.
  • DMD combined laser scanning, site surveys, engineering walkdowns and detailed draughting to establish an accurate record of the existing installation.
  • The project progressed beyond initial model creation to include P&ID completion, system tagging, model validation and physical valve identification on site.
  1. Sector
  • Industrial Manufacturing
  • Process Plant and Production Facilities
  1. Project Location
  • North West England
  1. Client Challenge
  • The client required reliable and coordinated engineering records for an established operational facility where existing plant information was incomplete or required verification.
  • P&IDs needed to be developed across several interconnected production areas while accurately representing continuations and tie-ins between systems.
  • The 3D model needed to capture different areas at appropriate levels of detail, balancing site-wide spatial awareness with higher accuracy in critical process areas.
  • Restricted access, insulated pipework and high-temperature working environments created additional surveying and validation challenges.
  • The resulting information needed to provide a dependable basis for future plant modifications, maintenance activities and engineering projects.
  1. DMD Scope of Work
  • Site-wide laser scanning and point-cloud capture
  • Site surveys and engineering walkdowns
  • Existing-condition verification
  • Development of a full suite of as-built P&IDs
  • Development of a site-wide 3D as-built model
  • Line numbering and service identification
  • Valve, instrument and equipment tagging
  • Physical valve tagging and validation walkdowns
  1. Engineering Disciplines
  • Piping
  • Engineering Surveying
  1. Project Delivery Approach
  • Initial laser scans and site surveys were completed to establish the physical arrangement of the existing facility.
  • The model was developed using a tiered level-of-detail strategy, allowing critical process areas to be modelled in greater detail than general buildings and infrastructure.
  • P&ID surveys were undertaken area by area, covering equipment, pipework, valves, instruments and process connections.
  • A dedicated site-based resource was used to progressively develop and validate the P&IDs and 3D model.
  • Final validation included physical valve tagging, supported by a client representative acting as the site acceptor during walkdowns.
