Typical situation
A plant is adding bins, feeders, or a new conveying line to an ingredient room that has changed many times since its last drawings. The designer laying out the expansion needs the room as it stands today: floors and steel, mezzanines, equipment, and the piping every new line has to route around.
What this scope includes
- Tier 1, scan. The agreed 10,000 sq. ft. is scanned at the dense-process rate. Setups are spaced closely so congested piping and equipment are captured at short range, where the scanner’s point accuracy is best, and from more than one side.
- Tier 2, building. Floors, walls, ceilings, roof geometry where safely captured, stairs, doors, and building-access ladders.
- Tier 3, process. External geometry and major visible connections of the equipment, the agreed piping systems down to an agreed minimum size, and mezzanines, access ladders, and guardrails. The process area is the full 10,000 sq. ft. Insulated lines are modeled as seen; insulation outside diameter does not establish nominal pipe size.
- Tier 4, drawings. Plans, an equipment layout, the mezzanine plan, selected elevations and sections, equipment tags, and agreed layout dimensions, with one consolidated review round.
How the package gets used
New bins and conveying routes are laid out in Inventor directly against the existing-condition model, then checked against the model and point cloud in Navisworks before fabrication. The drawing set gives operations, maintenance, and outside contractors the same current plan to work from.
What’s excluded
- Equipment internals and anything hidden behind insulation, lagging, or other equipment
- Detailed supports and fabrication details
- P&IDs, fabrication drawings, calculations, and permit documents, which are separate scopes
- Structural analysis and code certification
Fabrication-critical tie-ins, flange locations, anchor bolts, and tight-clearance dimensions need separate verification before fabrication or installation, quoted separately. Verification rule
