Green Civil Australia is looking for an experienced Senior Civil Estimator to take a lead role in shaping the pipeline of work that drives our business forward. This is a high-impact, Sydney-based position for a commercially astute estimator ready to move beyond supporting tenders to owning them — from first principles through to contract award. You'll bring deep technical expertise, sharp commercial judgement, and the confidence to lead complex, high-value tenders with minimal oversight, backed by genuine autonomy and a robust pipeline of civil and infrastructure work.

About the Role

Reporting to the Estimating Manager / Pre-Contracts Manager, you'll take ownership of the full estimating process for complex civil and infrastructure projects — from tender strategy and pricing through to submission, negotiation, and handover — while mentoring junior estimators and contributing to the commercial direction of the business.

Key Responsibilities

Lead full tender processes for complex, high-value civil and infrastructure projects, from go/no-go through to final submission

Develop tender strategy and win themes alongside senior management

Own detailed quantity take-offs, first-principles pricing, and cost benchmarking

Interpret complex tender documentation, identifying commercial risks and opportunities

Negotiate directly with subcontractors and suppliers on major packages

Drive value engineering to improve constructability and strengthen submissions

Manage commercial and contractual risk throughout the tender lifecycle

Engage directly with clients, principal contractors, and project stakeholders as the senior estimating representative





Mentor and develop junior and intermediate estimators

Oversee handover to delivery teams, ensuring commercial intent is clearly communicated

Skills & Experience

Minimum 10 years' experience in civil construction or infrastructure estimating, including leadership of complex, high-value tenders

Degree or diploma in Civil Engineering, Construction Management, Quantity Surveying, or related discipline

Proven track record winning large-scale, multi-million dollar civil and infrastructure projects

Strong commercial acumen and risk awareness across the tender lifecycle

Advanced proficiency in estimating software (Cubit, CostX, Candy, Benchmark, Expert Estimation or similar)

Demonstrated experience leading and mentoring estimating staff

Sound knowledge of Australian Standards and standard contract forms (AS4000, AS4300, GC21)

Experience in defence, data centre, renewable energy, or complex infrastructure sectors

Exposure to alliance, ECI, or design-and-construct delivery models

Current driver's licence

Typical Projects

Bulk earthworks, major road and pavement construction, stormwater and drainage infrastructure, concrete structures, retaining walls, demolition and remediation, utilities infrastructure, industrial developments, data centres, defence infrastructure, renewable energy projects, and large-scale land subdivisions.

What We Offer

A genuine leadership role with real autonomy and commercial influence, a secure pipeline of large-scale civil and infrastructure projects, a competitive senior-level remuneration package, and a collaborative team culture with clear progression opportunities.
