Engineer - Cost Estimation

Responsibilities

• Formulate methodologies for deriving quantities from design parameters.
• Support project teams on scenario comparisons, uncertainty analysis and sensitivities on cost estimates, reflecting analysis of project risks.
• Support reviews and assurance of cost estimates. Benchmark against historical performance, industry norms and established KPIs.
• Assess prospect scope and develop consistent estimates ranging from Type 0 to Type 4.
• Work with Planning & Cost Engineers to ensure alignment between planning and cost deliverables.
• Arrange Estimate Kick Offs and Estimate Review meetings with the stakeholders.
• Develop Estimate Plan detailing how the estimate will be developed.
• Develop Estimate Basis to document how estimate was developed.
• Support process to collect actual cost performance, condition and normalise data for future use, develop metrics and benchmarking information.
• Develop benchmarking packages at appropriate level to check estimate results from top down versus both internal and external comparable data. Work with IPA forms and reports to understand comparison of Shell projects to industry datasets.
• Utilise Technical, Economical, Commercial, Organisational & Political (TECOP) profile to establish appropriate deterministic cost contingency.
• Support development of deterministic cost model and probabilistic cost analysis.
• Support project teams with presentations, dashboards.
• Update SharePoint with Estimates, Benchmark data and relevant data for future reference.
• Provide assurance and challenge, as needed, on detailed project cost estimates (Type 4). Incorporate project actual costs to date and detailed MTOs from IFC (Issue For Construction) design packages matched with detailed pricing and construction unit hours to establish remaining project costs.
• Perform uncertainty analysis and sensitivities on cost estimates, reflecting analysis of project risks. Utilize appropriate deterministic or probabilistic risk assessment tools to develop the appropriate cost contingencies.
• What you bring
• Bachelor's degree in Engineering and/or Certification as a Cost Estimator or equivalent experience.
• Minimum 2 -10 years of experience in cost estimating positions in the Oil & Gas industry (operating refinery or petrochemicals plants preferred) on small capital projects portfolios.
• Fully versed with Cost Estimating Tools and Methodologies.
• Well versed with ASPEN TECH estimating tool
• Experience in cost risk analysis, preferably with both deterministic and probabilistic methods.
• Experience in sourcing and using benchmark data
• Excellent analytical, oral and written communication skills
• Team player and self-motivated.
• Advance skill level in MS Excel.
• Fully versed with MS Office suite of software (Word, Powerpoint and Outlook)
• Preferred experience in following tools: ASPEN TECH , CCET.
• Preferred experience in Electrical Projects or petrochemicals plant turnarounds.
