If you mean pricing quantity, then, payment will be made on the basis of plinth area measurements at ground floor only for all the stages of treatment in sqm. correct to two places of decimals. Rate includes the cost of materials, labour and all tools, plants, sprayers required for complete operation.

Further, if you meant quantity of concentrated chemical, you should follow manufacturer's recommendations of "application in terms of area", which obtained from "mixing of chemical to water ratio" as it may differ by different producers.

First of all thank you for the invitation.

consider:

A as the area for application (in square metres)

D as the water in which 1 ltr of chemical is diluted according to the manufacturer (e.g. for rate 1/19, D=19)

R: the applied rate of solution (chemical+water) according to specifications (e.g. 5 ltr/m2)

For 1 ltr of final -to be applied- material (solution) you used 1/(D+1) ltrs of chemical,

for 1 m2 of area you need R/(D+1) of chemical and finally

for your A m2 area, you need A*R/(D+1) of chemical (caution: just chemical, not chemical+water).

An example: area A=100m2, chemical/water ratio=1/19, so D=19, specified rate for application: R= 5 ltr/m2. Chemical quantity= 100*5/(19+1)= 25ltr.

If you look it the other way, for 100m2 you need 100*5=500ltr of solution(chemical+water). These 500ltrs consist of 1 part chemical & 19 parts water, so the chemical itself is 500/20= 25ltrs.

Input the underlined function in an excel and make your life easier.

Hope this is what you are looking for...

The quantity of chemical is usualy used to be ( 0.03 letter/ sq. metter )

so if you know the exact area the quantity(q) will be (q=0.03/area) ltrs.

It depend about the COEFFICIENT of the used material 

Example: 100 sqm and coefficient is 0.03 so 100 * 0.03 = 3 liter 

So u need 3 liters for 100 sqm

Got it...

Read the material data sheet to find out the coverage per liter (for example 10 square meter per liter). Then, devide the area by the coverage to calculate how many liters required.

Certainly! To calculate the quantity of termite proofing chemical needed when you have the quantity in area, you can follow these steps:

Determine the Application Rate: The application rate refers to the amount of termite proofing chemical required per unit area. This information is typically provided by the manufacturer or can be obtained from industry guidelines and standards.

Convert Area to the Unit of Application Rate: Ensure that the area is in the same unit as the application rate. If necessary, convert the area to match the unit of measurement used for the application rate. For example, if the application rate is given in liters per square meter (L/m²), make sure the area is also in square meters (m²).

Calculate the Quantity: Multiply the application rate by the area to calculate the quantity of termite proofing chemical required. The result will be in the unit specified by the application rate.

Here's the formula:

Quantity of Termite Proofing Chemical = Application Rate x Area

Make sure to double-check the units and ensure they are consistent throughout the calculation.

It's important to note that the specific application rate may vary depending on factors such as the type of termite proofing chemical, the level of infestation, and the construction requirements. Therefore, it is advisable to consult with a professional or refer to the manufacturer's guidelines for accurate calculations and recommendations based on your specific situation.

To obtain the required quantity of chemical, we normally follow the macufacturers recommendation in product catalog, or otherwise it is done in three layers, excavated area, backfilling area and third layer below the Grade Slab, For quantity estimation we take 1 litter for 50 square meter area into three layers, so average consumption is 15 m² per litter.

Different chemicals have a different Coverage which is mention backside of Chemical product. Simply divided total quantity ( Length x Width)  by Chemical Coverage, you will find total quantity if termite prof chemical.  

Formula 

Quantity of Chemical = Quantity (Length X Width)/ Coverage of Chemical (sq-ft or sq-meter)
