This tools and calculators make it easy to calculate the cost of materials, labor, tax, and other costs related to the project so as to be able to operate within budget.
What is a Bill of Quantity (BOQ)?
The Bill of Quantity (BOQ) is a list of all materials, labor, and other costs needed in a construction or engineering project.
The BOQ typically includes:
Codes and descriptions of items
Quantity of materials
Unit of measurement
Unit prices
Total cost per item
Other information such as taxes, wastage and labor cost
An appropriately prepared BOQ increases transparency and avoids conflicts while facilitating decision making by stakeholders.
Necessity of a BOQ Calculator
It is usually a time-consuming task to prepare a BOQ manually, and there is room for error, particularly in large-scale projects where hundreds of items are involved.
A BOQ calculator automates this tedious task and provides the following advantages:
Accuracy: Avoids human errors in calculations
Efficiency: Saves time on repetitive tasks.
Flexibility: Makes quick changes on quantity, price or other factors possible.
Transparency: Gives a clear description of costs to all stakeholders
Currency conversion: Helps in projects involving different currencies.
