When it comes to accurate construction estimation and cost control, two terms are essential: Material Constants and Labor Constants.
What are They?
Material Constants: These are standard quantities of materials required to complete a unit of a specific construction activity (e.g., how many bags of cement for 1 cubic meter of concrete).
Labour Constants: These define the typical quantum of labor (in man-hours or number of workers) required to execute a unit of specific work (e.g., how many mason hours needed for 10 sqm of plaster).
Why are They Important?
They allow precise project estimation—predicting consumption and costs before starting work.
By comparing actual consumption vs. constants, you spot wastage, inefficiency, or unusual variances early.
They make preparing Bills of Quantities (BOQ), tenders, and project billing much more systematic and reliable.

Why Do You Need These Constants?
To generate material consumption reports and track real costs.
For estimation, procurement, and billing—no guesswork, only accurate data-driven projections.
For resource planning and assessing workforce requirements.
