Staged engineering review

We review the engineering at defined milestones, before each decision becomes expensive to change on site.

30%
Concept and criteria
Basis of Design, layout and design criteria checked against site conditions, CAPEX and schedule.
60%
Basic engineering
Discipline coordination, interface management and a first constructability review.
90%
Detailed engineering
Interdisciplinary review, quantities, specifications and definition of work packages.
IFC
Issued for construction
Drawings and documents released for construction, with comments closed and risks logged.
Site
Field support
Technical queries (RFIs), engineering changes and as-built drawings through commissioning.

SUN & WIND develops and manages engineering with a focus on constructability, CAPEX, schedule, performance and risk reduction, integrating the civil, structural, electrical and infrastructure disciplines needed to take a project from its conceptual definition through execution and commissioning.

Our approach incorporates design criteria, actual site conditions, construction sequences, interfaces between disciplines, operational constraints and contracting strategy, allowing early identification of deviations that could affect the cost, schedule, quality or performance of the asset.

PRECONSTRUCTION, CONSTRUCTABILITY AND VALUE ENGINEERING

Reducing uncertainty before mobilizing resources to site

SUN & WIND integrates engineering, planning, costs and construction methodology during the preconstruction stage, identifying constraints, clashes, risks and optimization opportunities in advance. The goal is to establish an execution strategy that is technically robust, cost-efficient and contractually controllable before works begin.
