1. All dimensions are in millimeters, unless otherwise stated. 2. This drawing must not be scaled ,only figured dimensions should be used. 3. This drawing must be read in conjunction with relevant Architectural drawings. 4. Reinforced concrete to be grade 25 and blinding class 15 to BS 8110. 5. Cover to main reinforcement to be as follows: (a) Foundation = 50mm (b) Columns = 40mm (c) Beams = 30mm (d) Slabs = 20mm 6. "T" Denotes deformed high yield bars to BS 4449. "R" Denotes round mild steel bars to BS 4449. 7. Reinforcement in walls and columns must be inspected by the Engineer before being enclosed in the formwork. 9. All masonry walls must be reinforced with 25mm hoop iron after every two alternate courses. The hoop iron must be extended through the column sections. 10. To ensure enhanced bonding between the masonry and the R.C. columns, the masonry walling must be raised first before the columns are casted. 11. All mortar used to be of cement sand mix 1:3, with all the stone walling being laid in 200mm courses with 12mm mortar joints. 12. A minimum of 5.0N/mm2 average compressive strength of masonry in accordance with BS5390 should be used for all wall sections. 13. Mass concrete to be grade 15 14.
