Define the measurement boundary
State whether dimensions describe the complete enclosed package, the skid only or a separate component. Note attached protrusions and loose items that are outside the reported dimensions. Include units for every figure. A bare sequence such as 180 by 72 by 90 is ambiguous without labels and a measurement boundary.
Use sources that match the assembly
Attach manufacturer documentation or another reliable record where available and identify its model/configuration match. Record whether a weight is described as dry, operating or otherwise qualified by the source. Do not assume a catalog figure covers added tanks, trailers or later modifications; preserve those limitations in your notes.
Mark measured and estimated values differently
If authorized site personnel take accessible measurements, record the date, method and any obstructed dimension. Do not create a false sense of precision by adding decimal places to an estimate. Avoid climbing or moving equipment to obtain a sales measurement. Leave inaccessible values unconfirmed for a qualified site review.
Let the handling provider confirm suitability
Provide the information to the selected qualified removal or transport provider for its own planning. Your inventory is not a lifting plan or confirmation of route suitability. Record which values the provider still needs to verify before collection and who is responsible for obtaining that confirmation.
