Check the file name, then the number beside the model.
The Eng Hub is a UK reference for information-container naming, Common Data Environment state language, and the small preliminary calculations delivery teams actually run. It is not a structural or electrical design approval.
Start with the thing that fails first
Information-container name
Seven hyphen-separated fields. A project convention check, not a claim that ISO 19650 mandates the string.
GuideWIP, Shared, Published, Archive
What each state is for, and what people wrongly do with a Shared file.
CalculatorSimply supported reactions
UDL or point load. Reactions and maximum moment only. No section check.
CalculatorConcrete volume
Slab, pad or cylinder, with an order allowance. A quantity, not a mix design.
GuideISO 19650 in plain English
Appointing party, information requirements, and why the standard is not a software manual.
CalculatorCopper voltage-drop estimate
Go-and-return resistivity at 20°C. Labelled as an estimate, not BS 7671.
MechanicalPump power
Flow and head to kilowatts. Not a pump selection.
PipeworkPipe velocity
Straight-pipe velocity and Darcy head loss.
CivilPad bearing pressure
Average pressure only. Not Eurocode 7.
ElectricalThree-phase power
Balanced kW and kVA. Not a cable size.
Temporary worksFormwork pressure bound
Hydrostatic upper bound. Not CIRIA C766.
InfrastructureRational runoff
A peak-flow screen. Not FEH or a sewer design.
