Construction Cost Estimator (m2)

This calculator creates an early-stage construction budget scenario and breaks down where the total comes from, instead of showing a single opaque number.

It is useful in pre-feasibility, scope framing, and comparing multiple unit-cost assumptions before requesting contractor bids.

Total area (m2) represents the built area considered for costing. Unit cost (TRY/m2) is the modeled average rate reflecting material, labor, and execution quality assumptions.

Permit-operations share adds non-direct build costs such as permits, mobilization, and site administration as a percentage. Contingency share is a risk buffer for uncertainty in prices, supply, and execution.

The flow is: base cost = area x unit cost. Permit-operations cost = base cost x permit-operations rate. Contingency amount = base cost x contingency rate.

Total project cost = base cost + permit-operations cost + contingency amount. Final unit cost is total project cost divided by area. Since the model is additive, higher rates increase totals linearly.

The output is a mathematical result of your own assumptions and should be read as planning support, not as an official quantity survey or contract-ready estimate.

Read base, permit-operations, and contingency layers together. This reveals which component is driving budget pressure and where value-engineering discussions should start.

Example: area 900 m2, unit cost 23,000 TRY/m2, permit-operations 8%, contingency 12%. Base cost is 20,700,000 TRY.

Permit-operations adds 1,656,000 TRY and contingency adds 2,484,000 TRY. Total becomes 24,840,000 TRY, and final unit cost reaches 27,600 TRY/m2. This helps set bid-evaluation ranges before procurement.

The tool improves decision speed and budget visibility, but it does not independently model geotechnical risk, structural complexity, MEP scope, or project delivery constraints.
