Construction Estimator

A construction estimator prepares detailed cost projections and material schedules for building and civil projects by analysing design specifications, site conditions, and current market rates. They work with architects, engineers, and project managers to quantify labour, materials, plant, and overheads, then produce tender documents and budget forecasts that inform project planning and commercial decisions.

Measure and quantify building elements from architectural and engineering drawings using digital takeoff software and manual scale rules. Research and compile current rates for labour, materials, plant hire, and subcontractors through supplier quotations and industry pricing databases. Calculate labour productivity and duration estimates based on crew size, task complexity, site conditions, and relevant Australian Standards (AS/NZS standards for construction). Apply mark-up and contingency allowances for risk, overheads, profit margin, and project-specific factors such as remote locations or difficult terrain. Prepare tender schedules of rates and lump-sum estimates formatted to suit client specifications and tender requirements. Itemise provisional sums and prime cost items for client variation and supply requirements. Coordinate with subcontractors and material suppliers to obtain firm quotations and validate cost assumptions. Conduct site inspections to assess ground conditions, access, and logistical constraints that affect construction method and cost.

The standard entry pathway requires a diploma, advanced diploma or associate degree (ABS skill level 2). Specific qualification requirements vary by employer and state. Some employers may accept equivalent experience. Check yourcareer.gov.au for available courses and dewr.gov.au/skills-reform/free-tafe for subsidised training options.

You're doing detailed maths and measurement work all day, often under tight deadlines when tenders are due. Small errors in your estimates can cost projects hundreds of thousands of dollars, which means stress and accountability. Pay typically caps out below senior management level unless you move into project management or start your own quantity surveying practice.

Some work for consulting firms in regional centres, but most regional construction uses estimators based in the nearest city. Remote work is possible for office-based estimating, but site inspections mean you'll travel.

Published for ANZSCO unit group 3121, the wider group this job sits in, not for this job on its own.

This is the median for full-time employees who are not managers and are paid at the adult rate, before tax and salary sacrifice. It is a guide to what the work pays, not a wage rate.
