Contracting models

Contracting and execution models

Flexible structures tailored to each project’s scope, level of development and contracting strategy

CONTRACTING AND EXECUTION MODELS

SUN & WIND structures its involvement around your technical, contractual and operational needs, and can take part from early studies and engineering through construction, full project management, commissioning and handover.

The contract model is defined based on scope, risk allocation, engineering maturity, procurement strategy, interfaces, schedule, CAPEX and the level of control the owner requires.
