GENERAL NOTES 1. Do not scale from drawings; written dimensions govern. Verify on site and report discrepancies to the Architect. 2. Units: dimensions in mm, levels in metres. Ground floor FFL ±0.00 (= +0.45 m above finished ground). 3. Compliance: Ghana Building Regulations (LI 1630, 1996), Ghana Building Code (GS 1066:2018) and local MMDA/Development Planning Dept. requirements — to be verified by the registered architect/planner before submission. 4. Structure: RC frame (columns/beams/slabs) with sandcrete block infill, designed by a registered Structural Engineer (GhIE) after a geotechnical investigation. Foundation depth/type shown in sections is indicative only. 5. Walls: 225 mm external, 150 mm internal sandcrete blocks (min. 3.5 N/mm²), plastered both sides. DPC 150 mm above ground. 6. Termite pre-treatment of soil and plinth; 1000-gauge polythene DPM under 150 mm ground slab on compacted hardcore. 7. Climate: hot-humid, ≈ 1 500–2 000 mm rain/yr — flat roofs min. 1:60 fall, 900 mm parapets, rainwater pipes to U-drains, plinth 450 mm, cross-ventilation to all habitable rooms, projecting canopies for sun/rain shading. 8. Internal wet rooms (visitor WC, Bed 4 ensuite) and utility room have no external wall: mechanical extract required. 9. Electrical: ECG supply; provision for generator change-over and PV/inverter (≈ 5 kWp). MEP design by licensed engineers. 10. Water: GWCL main + borehole + 5 000 L ground tank + 2 × 2 000 L roof tanks. Sewage: septic tank & soakaway (A-01). 11. Fire & safety: min. 2 extinguishers per floor, smoke detectors, 1.1 m guard rails at stairwell, terraces and roof terrace. 12. Orientation (street to the south) is assumed; north arrow and boundaries to be confirmed by a licensed surveyor. 13.
