Key Responsibilities
- Develop, coordinate, compile, integrate and maintain Class 5 through Class 3 cost estimates, incorporating and reconciling estimate inputs from engineering contractors, consultants, vendors, partners and internal disciplines using methodologies appropriate to the maturity of project definition.
- Prepare complete estimate deliverables, including quantity take-offs, cost models, estimate workbooks, pricing summaries, basis-of-estimate documentation, assumptions, exclusions, qualifications, escalation, productivity factors and cash-flow profiles.
- Review project scope, engineering deliverables, design criteria, execution plans, schedules, contracting strategies, technical studies and vendor or contractor proposals to confirm estimate completeness, alignment and traceability.
- Work with Engineering and Construction teams to translate technical definition, constructability, sequencing, logistics, temporary works, site access and field execution requirements into credible estimate inputs.
- Lead and support estimate challenge sessions, validation reviews, benchmarking, normalization and reconciliation activities; identify differences in scope, estimate basis, pricing basis and assumptions, and clearly explain material changes, uncertainty, cost drivers and sensitivities.
- Support quantitative and qualitative risk assessment, contingency development and management reserve analysis by connecting identified risks and opportunities to potential cost and schedule outcomes.
- Provide estimating input to option selection, business cases, stage-gate and assurance reviews, funding requests, sanction decisions, change evaluations and executive or partner governance materials.
- Collaborate with Supply Chain and Commercial teams to incorporate market conditions, contracting approaches, bid information, vendor quotations, labour assumptions, commodity pricing and escalation into project estimates.
- Partner with Cost Control, Scheduling and Risk to align estimate structures with the work breakdown structure, cost breakdown structure, schedule, risk register, control accounts, forecasting and performance reporting.
- Maintain estimating databases, cost libraries, norms, productivity factors, benchmarks and historical project information, with clear source documentation, version control and data-quality standards.
- Establish and continuously improve Pacific Link estimating procedures, templates, tools, coding conventions and assurance practices in alignment with Project Controls governance and business requirements.
- Provide functional guidance and constructive challenge to project teams, partners, consultants and contractors, promoting consistent estimate quality, accountability, transparency and stewardship of project information.

- Proven experience developing, compiling, integrating and reconciling major capital project estimates from early concept through project definition and sanction, with practical knowledge of procurement, contracting, construction sequencing and schedule interfaces.
- Strong knowledge of AACE estimate classification, basis of estimate, validation, escalation, contingency and cost-risk analysis.
- Owner-side experience challenging and integrating estimate inputs from consultants, contractors, vendors and partners.
- Strong analytical, communication and relationship skills, with the ability to present complex cost information clearly and maintain independence under competing priorities.
- Proven organizational skills with the ability to manage priorities, meet deadlines, and maintain attention to detail in a fast‑paced environment.
