Dokainish & Company has delivered project controls and project management consultancy services to owners and developers across North America and the Middle East since 2011, specialising in project controls, project management, quantitative risk analysis, estimating, and enterprise reporting for major capital projects.

We are seeking a Senior Estimator to join a high‑performing program controls team supporting a major, long‑duration nuclear decommissioning and radioactive waste management program. The incumbent will own the end‑to‑end development of project cost estimates and supporting documentation across a complex, multi‑project portfolio, spanning reactor decommissioning, radioactive waste facility operations, environmental remediation, and fuel processing programs.

• Develop project‑level baseline cost estimates (AACE Class 3–5) across a diverse portfolio of nuclear decommissioning, waste management, and remediation projects.
• Produce comprehensive Bases of Estimate (BOE) for each project, including methodology narrative, source data, escalation rationale, key assumptions, exclusions, and stated accuracy range.
• Apply parametric, analogous, and bottom‑up estimating methodologies; select the appropriate approach based on available information and document the rationale explicitly.
• Develop time‑phased cost profiles integrated with project schedules; collaborate with senior schedulers on cost loading, resource histograms, and S‑curve generation.
• Provide cost uncertainty inputs (P10/P50/P90 distributions, key cost drivers) to the project risk and quantitative risk analysis process.
• Establish and apply consistent estimating norms and unit rates scaled to project complexity and information maturity across the portfolio.
• Support program‑level planning deliverables: resource allocation plans, escalation profiles, and multi‑year cost projections.
• Respond to queries on estimate basis and methodology with traceable, well‑documented backup within defined timelines.

• Minimum 10years of capital project estimating experience; strong experience in nuclear decommissioning, radioactive waste management, environmental remediation of nuclear‑contaminated sites, or capital projects within licensed nuclear facilities (CANDU, research reactors, fuel processing, isotope production, or equivalent) is strongly preferred.
• Demonstrated experience preparing estimates across AACE Class 1–5 on projects of significant scale and complexity.
• Strong BOE authorship track record; document samples will be requested during the interview process.
• Experience in multi‑project program environments with concurrent estimate workloads.
• AACE membership in good standing; CCP, CEP, or PSP designation preferred.
• University degree in Engineering, Construction Management, Applied Sciences, or a related field; equivalent combinations of technical certification and demonstrated experience will be considered.
• Must be eligible for Canadian nuclear facility security clearance; existing clearance is an asset.

Submit a Basis of Estimate (BOE) document sample with your application. Redact any confidential client or project information. Applications without a BOE sample will not be considered.
