Constructability review & product feedback loop — Review Leviathan/Galleon MDC and site designs (civil, structural, architectural, mechanical, electrical, piping, controls, ICT, IT) at each stage gate and feed constructability input directly into product development — modularity, transport and lifting constraints, ISO container/skid interfaces, installation sequencing, and commissioning strategy — catching buildability issues while they are still cheap to fix, before they are locked into issued-for-construction drawings. Constructability governance, documentation & readiness sign-off — Build and maintain constructability guidelines, buildability/site-readiness checklists, and review workflows by geography; track open constructability items and lessons learned across active sites; and provide the final constructability sign-off confirming a site's design and execution plan are buildable and ready to proceed to construction.efinitions.
