Job Description
SENIOR ESTIMATOR
n
Price the opportunity. Understand the risk. Help secure the projects that build Alfabs' future.
n
Alfabs Engineering & Services isn't just another contractor in the market. As the flagship division of the ASX-listed Alfabs Group, we deliver complex engineering, fabrication and construction solutions across some of Australia's most demanding industries - including infrastructure, mining, energy and construction.
n
And we're growing.
n
As our project pipeline and capability continue to expand, we're looking for an experienced Senior Estimator to join our team and play a key role in identifying, developing and securing the next generation of major projects for Alfabs Engineering & Services.
n
This is more than simply producing estimates.
n
Working closely with our Business Development & Engineering teams you'll take ownership of complex tenders and help develop commercially sound, technically robust and competitive submissions. You'll be involved from the early stages of an opportunity - understanding the scope, developing the estimate, identifying risk, testing methodology and challenging assumptions - right through to tender submission, negotiation, handover and post-project review.
n
You'll have genuine input into what we pursue, how we price it, how we manage the risk and how we position Alfabs to win.
n
THE OPPORTUNITY
n
As Senior Estimator, you'll work across a diverse portfolio of opportunities, including major projects typically within the $10M-$40M range.
n
You'll work with Estimating Team and wider business to develop accurate, competitive and deliverable estimates while ensuring tenders are compliant, commercially considered and submitted on time.
n
This role suits an estimator who has built robust technical and commercial capability and is ready to take greater ownership of complex tenders, contribute to bid strategy and become a trusted senior member of the estimating function.
n
Your key responsibilities will include:
n
n
Coordinate the preparation of detailed, accurate and commercially sound estimates and tender submissions for complex engineering and construction projects.
n
Review drawings, specifications, scopes and tender documentation to develop detailed labour, material, plant, subcontractor and project cost estimates.
n
Work with the Estimating Team to manage tender activities, priorities and workloads, ensuring compliant, high-quality submissions are delivered on time.
n




Partner with the Business Development Manager to review new opportunities, contribute to Go/No-Go assessments, and develop competitive tender strategies.
n
Collaborate with Engineering, Operations, Projects and Construction teams to develop practical methodologies, resource plans, programs and delivery strategies.
n
Develop subcontract packages and scopes of work, obtain market pricing, and critically assess supplier and subcontractor submissions.
n
Identify and assess commercial, contractual, technical and delivery risks, including contingencies, qualifications, exclusions and contractual departures.
n
Support client engagement, tender clarifications, negotiations and ECI activities, working with internal stakeholders to strengthen tender outcomes.
n
Maintain tender registers, pipeline and forecasting information, and support the effective handover of successful tenders to Project and Operations teams.
n
Provide guidance to the Estimating Team and drive continuous improvement across the tender lifecycle, including reviewing won/lost tenders and completed projects against estimates to capture lessons learned.

ABOUT YOU
n
You understand that winning the right work isn't simply about being the cheapest.
n
It's about understanding the scope, knowing where the risk sits, developing a realistic delivery strategy and producing an estimate that is both competitive and commercially sustainable.
n
You're comfortable getting into the detail, but you can also see the bigger picture.
n
You can interrogate drawings and specifications, challenge assumptions, assess subcontractor pricing, discuss construction methodology with operational teams and clearly communicate the commercial rationale behind an estimate.
n
Most importantly, you take ownership.
n
You'll ideally bring:
n
n
5-7+ years' estimating experience within construction, engineering, infrastructure, mining or a related heavy industry environment.
n
Demonstrated experience developing detailed estimates for projects in the $10M-$20M+ range, with exposure to projects valued up to approximately $40M.
n
Strong experience developing subcontract packages and scopes of work for market pricing.
n




Demonstrated knowledge of construction methodologies, project delivery and commercial risk.
n
Experience assessing tender opportunities and contributing to Go/No-Go governance decisions.
n
Strong understanding of project risk, contingency development and commercial evaluation.
n
Experience working with Tier 1 clients and ideally exposure to Early Contractor Involvement (ECI).
n
The ability to support, mentor and share knowledge with less experienced members of an Estimating Team.
n
Tertiary qualifications in Engineering, Construction Management or a relevant trade/technical qualification.
n
Advanced Microsoft Excel capability and strong proficiency across Microsoft Office and Microsoft Project.
n
Exceptional written, verbal and presentation skills.
n
The ability to manage competing priorities and multiple major tenders simultaneously.
n
