On most Dubai projects, drainage products are approved before they are ordered. The consultant, and sometimes the authority, reviews a submittal for each item. A complete submittal gets approved first time; a missing document means a rejection, a resubmission and a delay on site.
What a typical submittal includes
| Document | What it shows |
|---|---|
| Product data sheet | Description, dimensions and features |
| Material and grade | For example SS 304 or SS 316, PVC, ductile iron |
| Sizes and quantities | Each size against the drawing reference |
| Drawings | Dimensions, outlet positions and fixing details |
| Finish | Matte, mirror, brushed or coated |
| Duty rating | Light-duty or heavy-duty for gratings and covers |
| Compliance documents | Test reports or certificates, where the specification asks for them |
| Samples | For finish or detail approval, when requested |
Common reasons for rejection
- The wrong grade, such as SS 304 where SS 316 was specified.
- A missing drawing or dimension.
- No duty rating for gratings or covers in traffic areas.
- A finish that does not match the specification.
Tips for a fast approval
- Check the specification section and any approved product list first.
- Submit one complete pack per item, not documents in pieces.
- Reference the drawing and BOQ item on every page.
- Ask the consultant early if a document is unclear.
