Detailed Engineering Design Review Process

A structured four-stage workflow that ensures every design document is technically sound, fully compliant, and ready for construction execution.

01

Finalize MDL for EPC

We establish a contractually binding Master Document List, defining all drawings, schedules, and review scopes before engineering begins to prevent gaps.

02

Design Review & Comments

We iteratively review EPC documents against codes and MTRs, issuing actionable comments to eliminate errors and optimize design before procurement begins.

03

Design Approval — Issued For Construction (IFC)

We issue formal IFC approval once documents meet all standards, authorizing construction and procurement while providing bankable documentation for lenders.

04

Finalize Project Schedule

We review and approve the EPC schedule to ensure it is realistic, properly sequenced, and protects your project's target Commercial Operation Date.

DED Deliverables &
Documentation Package

A comprehensive set of technically verified, IFC-approved engineering
documents that form the definitive design basis for your solar power plant.
