Hi! Can you help me compute the concrete and masonry works for this structure based on the attached elevation drawing?The image shows the side view of a small building with labeled sections, wall openings (windows), and dimensions in centimeters.
Specifically, I need help computing the following:
For Concrete Works:
Volume of concrete for footings, columns, and slab (if applicable)
For Masonry Works (CHB Walls):
Total wall area (excluding window openings)
Number of CHBs required (based on 0.4 m x 0.2 m CHB)
Cement and sand for block laying
Cement, sand, and gravel for core filling (if reinforced)
Cement and fine sand for plastering (both sides)
Rebars needed for CHB reinforcement (if any)
Please base it on the drawing dimensions. Let me know if additional assumptions or standards are needed (e.g., CHB size, mix ratio, thickness of plaster). Thank you!
