The quantification methods for equipment and fixtures can vary according to the available information:
If the items are modeled:
They should be quantified by type and specification. The measurement unit may vary based on the nature of the element:
Count (Each): Pumps, valves, drains, etc.
Length (m or ft): Gutters and other linear elements.
If the items are not modeled:
They should be included in a total sum, clearly described and specified within the corresponding Bill of Quantities (BoQ) item.
