Drawing & BOQ Requirements
What Information Is Needed for a Fabrication Quotation
The more complete the drawings and technical documentation, the more accurate the review and quotation. If documentation is incomplete, you can first submit available materials, and ZhongSai will further confirm what is needed for fabrication and quotation.
Have Complete Drawings
- Structural drawings (architectural / structural)
- Shop drawings (if available)
- Bill of Quantities (BOQ)
- Project technical specifications
- Project country
- Surface treatment and special requirements
Incomplete Documentation
- Project country
- Available drawings or sketches
- Component types and approximate quantities
- Project use and basic dimensions
- Known technical requirements
- Submit available materials for initial review
* PDF drawings, BOQ or other available project documents can be submitted for initial review. Additional drawings, specifications or technical information may be required before the final fabrication scope and quotation are confirmed.
Export Project Fabrication
Structural Steel Fabrication for Overseas Export Projects
ZhongSai provides drawing-based steel component fabrication for overseas contractors, engineering firms and procurement teams, with export packing, container loading and delivery preparation support.
Packing & Container Loading
