How can u calculate quantities for estimations as per component wise like BBS, Cement, aggregate and their senorages.

Question

Accepted Answer

To calculate quantities for estimations, use Bill of Quantities (BBS) for components and consider storage requirements.

Create a Bill of Quantities (BBS) for each component, specifying the required quantities.
Consider the storage requirements for each component, such as cement bags, aggregate piles, etc.
Calculate the quantities based on the project specifications and design requirements.
Take into account any wastage or additional quantities needed for contingencies.
Example: For cement, calculate the quantity based on the required strength of concrete and the mix design.
Example: For aggregate, calculate the quantity based on the volume of concrete and the desired aggregate-cement ratio.

Accepted Answer

First we can find the volume of concrete for 1m3 so we can use on different volume for cement, sand, aggregate.

Accepted Answer

calculate quantities of materials for 1 m3 of concrete (By volume).let us assume the mix proportion is 1 : 2: 4 (Cement : Sand : Stone = a:b:c)

Volume of wet concrete = 1 m3

Accepted Answer

Calculate quantities as per site MIx design ratios which are used in your site execution for different components like PCC , Concrete M30,M25.., Cement mortar ratios...,Tiles, false ceiling, painting, plumbing, electrical...etc and then estimate give rates with help of SSR rates.
