What is a Estimator?

An Estimator works out the cost of a construction project before work begins. They calculate costs for materials, labour, and plant, then share these figures with architects, builders, and surveyors.

Estimators work across homes, offices, and civil works. They study plans and specs, get quotes from suppliers, and help teams decide if a project makes financial sense.

The tender process is a core part of the role. Estimators put together bid documents that lay out the full cost of a job. A sharp bid can win contracts and set a firm up for a strong year.

This career suits people who enjoy numbers, problem-solving, and project teamwork. Construction is growing in Australia, so good Estimators are in steady demand.

  • Read and study plans and specs to work out project scope
  • Prepare detailed cost plans for labour, materials, plant, and overheads
  • Put together tender documents and submit bids on time

  • Contact suppliers and subcontractors to gather and compare quotes
  • Update cost plans when project scope changes
  • Track project budgets and flag cost changes to the project manager
  • Help construction managers, architects, and surveyors with project planning
  • Read building codes and rules to make sure estimates comply

What skills do I need?

Estimators need a mix of technical skill and people skills. They must read complex plans and understand how building works. Good use of software like CostX or Buildsoft is key.

Strong number work is a must. Estimators work out material amounts, labour rates, and overhead costs with care. They need clear writing and speaking skills too, as they share findings with clients and project teams all the time.

Problem-solving and eye for detail count every day. Estimators often juggle many projects at once. Good time use and planning are just as vital as technical skill.
