Methodology
Execution methodology
A structured process from opportunity definition to operational handover
SUN & WIND structures every project through technical and management control stages, setting progress criteria, responsibilities, deliverables and decision points throughout the entire life cycle.
The methodology integrates engineering, procurement, construction and commissioning under a common framework of scope, schedule, cost, quality, safety and risk, maintaining traceability from the initial decisions through project close-out.

Collaboration model
A long-term technical relationship, from identifying opportunities to execution
SUN & WIND proposes a progressive collaboration model to identify concrete opportunities within projects in development, construction or operation, assess them technically and turn them into executable scopes with measurable impact on cost, schedule, constructability, energy efficiency and performance.
The model lets you start with specific interventions and scale up to engineering, construction, project management or integrated energy solutions as your needs require.
- 01
Technical assessment
- Review of current and future projects
- Analysis of engineering background information
- Review of specifications and design criteria
- Identification of technical constraints
- Constructability assessment
- Review of interfaces between disciplines
- Identification of execution risks
- Assessment of electrical infrastructure
- Review of energy opportunities
- Preliminary identification of optimization opportunities
Outcome: Technical map of opportunities, constraints and potential areas of intervention.
