| THIS IS A DESIGN-INTENT ENQUIRY SCHEDULE, NOT A STRUCTURAL BILL OF QUANTITIES. No structural drawings were issued with the KV2 package - no foundation or pile layout, no framing plans, no sections, no bar schedules. Every specification below is either read off the architectural drawings or is normal Maldives marine practice researched for this project. Quantities are deliberately blank: they cannot be established from room areas. Use this to obtain budget rates and lead times, and to define what the structural package must resolve. | | | | | | | | | | | | |
| STATUS KEY D = confirmed by the drawing information issued. A = assumed design intent or preliminary specification, absent from the package. ALT = a priced alternative to the item above it, not an addition. | | | | | | | | | | | | |
