About Cesar

I support Owners, EPCM/PMC and investors in structuring and executing procurement and contract management for complex CAPEX projects. My role is to bring clarity, control and commercial discipline from FEED and pre-tender phases through award and execution.

I typically step in when procurement category/strategies are not well defined, tender processes need experienced leadership, or contracts start drifting during execution, including claims management and prevention. I work hands-on, close to project teams, focusing on decisions that are defensible, documented and aligned with project risk.

Core areas of support

- CAPEX procurement and contracting strategy (FEED to tender)
- Package definition and tender management (RFP/RFQ, evaluations, negotiations)
- Commercial contracting and risk allocation
- Contract administration, variations and claims prevention
- Supplier performance and commercial recovery

I operate as an interim lead or project-based consultant, integrating with engineering, construction, commissioning and supply chain teams. My approach is pragmatic and execution-driven, designed to withstand audits, lender scrutiny and senior management review.

If you need experienced commercial leadership to stabilize procurement, contracts or tender processes in a CAPEX project, I can step in quickly and deliver value.
