Hlo sir ! In my region people directly uses to place the PCC footing ( generally ,2.5'×1.5') and then do the bricwork on the it .Then after few years cracks start to develop ( may be due to drying shrinkage) . My point is , If we do the same thing what specifications must be setisfied ? So that cracks might not develop.

@Civil_Guruji
@Civil_Guruji 22 күн бұрын
@nirajsingh577, compound wall ki costing nikalne ke liye aapko kuch basic steps follow karne honge: Measurement: Sabse pehle, aapko wall ki length, height, aur thickness measure karni hogi. Material Calculation: Uske baad, material ki calculation karni hogi, jisme bricks, cement, sand, aur koi bhi reinforcement material shamil hai. Labour Costs: Is project mein kitna labour lagega aur unka cost kya hoga, ye bhi estimate karna hoga. Additional Costs: Any other costs such as transport, machinery rental (if needed), and miscellaneous expenses should also be considered. Quotes: Different suppliers and contractors se quotes lena helpful ho sakta hai to get an idea of the market rates. Is information ka use karke aap ek detailed budget bana sakte hain. Agar possible ho to kisi experienced contractor se bhi is budget ko review karwane ki koshish karein, to ensure that your estimates are realistic.
