What is Cost Estimation in the Building and Construction Industry?

Construction cost estimation is a process that predicts the actual costs of a building project. A cost estimate is calculated using the inputs of labour rates, material costs, and task duration. It provides a financial baseline for a project, which is used to bid on contracts, budget resources, and control costs.

The Importance of Construction Cost Estimation

Accurate construction cost estimation is an essential step for the success of any construction project. It helps in:

  • Budgeting: A cost estimate facilitates budgeting and securing funding for the project.
  • Decision making: It aids in making informed decisions regarding project feasibility and execution.
  • Risk management: It helps identify potential financial risks and develop mitigation strategies.
