About the Opportunity

Amentum are seeking a Cost Estimator to support the ITER Project. You will support the engineering and delivery teams in the negotiation of estimate values where there is dispute between parties. Knowing where contractors are presenting unreasonable proposals and having a sound basis of costs to be able to support this position are vital tools. Where negotiation is required, the estimator must be able to present a coherent and realistic argument, and always consider the best interests of the project.

The Client’s specific cost database is in the process of development with some information already available for use. Nonetheless, it can often be the case for specific components that estimating norms are unavailable and experience of working with Control Account Managers to develop a valid estimate basis is necessary because of the project specificity. The Cleopatra knowledge base and tool will be provided, in your role you will be will be encouraged to use Cleopatra where appropriate to the work being estimated. Cleopatra will in any case be the primary tool used for any cost estimates related to assembly and installation works. The cost of assembly and installation is already prepared. The work in this area therefore focuses on any scope changes and allocation of work and cost to specific contracts. You'll work to validate the cost of Direct Implementations (DI) between stakeholders, and of Ordre de Service between the owner and their contractors, as part of the construction works.

You'll review and validate cost estimates related to PCRs with reasoning on any disagreement on cost that is substantial. This work not only requires validation of costs, but also requires that the scope of the change is fully and traceably identified in the estimate. Note that this work includes verification of the design change applicable date as before. Where PCR cost estimates cannot be supported, engage with the PCR authors and engineering. Key responsibilities will be:

• PCR cost estimates and Cost estimates

• BCPs review results

• Production of a list of cost savings and cost avoidance achieved and potential

• PCD support in elaborating price breakdowns and financial price offer analysis

• Position Papers on ownership of scope or eligibility for compensation

• Certification by Association for the Advancement of Cost Engineering (AACE) or the International Cost Engineering Council (ICEC) or equivalent

• Knowledge of P6 and SAP

• Understanding and experience of Baseline control and management

• Demonstrable competence in the use the Cleopatra estimating software (in particular for work relating to the Assembly and Installation work and contracts)

• Cost Estimating Officers allocated must have between 5 and 10 for an intermediate position, or over 10 years for senior position

• The project language is English

• Access to cost reference information from a wide range of industries is a valuable addition to the service, to supplement where conventional reference sources are unavailable, and to provide supplementary information for comparison purposes
