I need Engineers/BQS in the house to help me with the quantity of the following materials that will be required to construct a decking slab for an area of approximitely 12.5M x 5.8M. Only the quantity of the materials;

1. Bag of cement
2. Sand
3. Granite
4. Rod - Y16
5. Rod - Y12
6. Rod - Y8
7. Wood - 1 X 12
8. Wood - 2 X 3
9. Ply wood - 4ft X 8ft

NOTE: Attached is the design plan of the structure that will be built on the slab area

Let me help you roughly,
1. 45bags of cement
2. 1/2 tons of 12mm rod
3. 15tons granite
4. 20tons shap sand
Pls for more details and others get a QS. Thank you.

Remember no details for beams and no drawing as well. The above is an approximate estimate from first principle. Also, note that I don't subscribe to 8mm rods for slab/deck work. Your deck is a small surface area with 150mm thickness a guess. That is what my rough estimate is base on.
