Every pipe piece has a place in the calculation.
A drawing alone cannot settle a close pipe-volume question. EngineCore records the actual network, identifies each piece and relevant fitting, and applies the calculation method in the controlling manufacturer instructions.
Use exact measurements where the margin is uncertain.
A detailed inventory is most useful when the apparent pipe volume is close to the system's limit, the field route differs from the drawing, or an added branch could change the calculation. The applicable manufacturer instructions control which measurements and fittings count.
Record the network
Identify the cylinder or supply, branches, endpoints, pipe pieces, fittings, sizes, and measured lengths. Unknown field conditions remain marked open.
Draw one connected model
Give each piece and component a tag. The isometric and physical parts list refer to those same tags, so a reviewer can follow each item back to the record.
Apply the source method
Use the identified manufacturer, model, and manual revision. Report the calculation basis, result, reviewer confirmation, and limits of the available evidence.
A second isometric for the section that would change.
If a small section needs to be added or modified, the proposed work can be documented separately from the existing network. Repair tags identify only the planned pipe pieces and components; the accompanying list gives quantities and part details for that section.
Repair detail R-01
- Connection
- Identify the verified tie-in point on the as-found record.
- Drawing
- Show the new or modified route as its own tagged isometric.
- Parts
- List each proposed pipe piece, fitting, size, length, and quantity by tag.
- Verification
- Recheck the affected manufacturer limits against the proposed final configuration.
Existing and proposed stay distinct.
The as-found drawing records the observed system. The repair drawing describes a proposed configuration and does not state that any work has been installed, tested, inspected, or approved.
Field measurements and the exact manufacturer source are required before a repair list can be issued as a verified scope. Pipe verification and repair planning are quoted separately from the $199 base Site Compliance Review.
One model, a drawing, and a parts ledger.
The existing submittal example shows a full tagged TANK piping arrangement and the detailed sheet information that stays off the main page. It is an example of a specific application, not a default rule for every system.
