Define enforceable line items; confirm missing values with ALFA.
Show what an engineer should define in BOQ/specification line items — without filling missing ALFA values.
| Field | Example guidance |
|---|---|
| Product type | Pressure pipe / gravity sewer / DWV / conduit / perforated |
| Material | uPVC / CPVC / … (do not mix properties) |
| Nominal diameter | DN or NPS — clarify OD system |
| Pressure class / SDR / Schedule / SN | As project + ALFA availability |
| Standard | e.g. DIN 8062, ASTM D1785, DIN 19534 |
| Joint type | Solvent weld / elastomeric / … |
| Length / unit | m, length each, or factory lengths |
| Fittings | Matching standard family |
| Testing | Per project ITP |
| Documentation | Datasheet, COC, MAR pack |
If a dimensional/rating cell is blank on the website, write confirm with ALFA — do not invent.
This engineering resource explains Boq Specification for designers and reviewers. Use it to clarify definitions, methods, and limitations—then apply project-specific data.
Document formulas and variable definitions when performing calculations. Call out where soil modulus, temperature derating, or surge dominates the result. Link outcomes back to product standards and application hubs for procurement.

Standard, size/pressure class, jointing system, quantities/lengths, fittings list, delivery location, and any submittal/test requirements from the specification.
Not without review. Dimensions, pressure classes, and test methods differ across standard families.

Batch-1 knowledge update: ALFA-specific order data must come from approved submittals—this section does not invent ratings or certifications.
