As a federal Crown corporation, Trans Mountain continues to build on more than 70 years of experience delivering operational and safety excellence through our crude oil pipeline system. With our expanded pipeline system now in place, Trans Mountain provides enhanced direct access for Canadian crude oil to world markets. The expansion realizes a world-class system for oil transport, developed to Canada’s high standards within one of the most stringent regulatory regimes in the world, creating long-term economic advantages, enhanced marine protection, enhanced safety and emergency management capabilities, and enhanced skilled-worker capacity building in communities and Indigenous groups. Each obstacle we’ve overcome or success we’ve experienced has been the result of a shared commitment to living these values every day.

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.
