For estimation of any project first step is estimation of?
Material cost
Labour cost
Service charge
Profit/Loss
Material cost
In electrical estimation and costing, the first and most critical step is the quantity survey or estimation of material. This provides the base for determining the total project cost by quantifying items like wires, conduits, switches, and distribution boards required to complete the installation.

TotalCost=MaterialCost+LabourCost+Overheads+Profit
The estimation process follows a hierarchical structure where material requirements are identified first based on the layout and design specifications. Once materials are quantified, labor charges, overheads, and contingencies are calculated as a percentage or fixed rate based on the material cost, making material estimation the fundamental starting point.
Quantity Surveying (QS) is the primary step in any electrical project estimation.
Material list includes detailed specifications such as size, rating, and quantity.
Labor cost is generally estimated as a percentage (e.g., 10-20%) of the material cost.
Service charges and contingencies are added only after determining the material and labor base.
Ensures accurate budget planning.
Helps in procurement scheduling to prevent project delays.
Subject to price fluctuations in the market.
Requires precise technical drawings/blueprints before commencement.
Residential building wiring
Industrial power plant installation
Commercial office electrification
Estimating material first ensures that the bulk of the project expenditure is locked before variables like labor efficiency are applied.
Option B (Labour cost) is secondary because it is usually derived from the extent of work defined by the material quantity.
Option C and D are overheads or final financial additions added to the subtotal of material and labor.
A is correct тАФ The estimation of material quantity is the essential first step that dictates the scope and primary expenditure of any electrical project.
Always remember that in BOQ (Bill of Quantities) preparation, materials are itemized first; never base your labor calculations until the material list is fully finalized.
