Design Management & Owner's Engineer — Multi-Discipline Substation Packages

Large substation packages involve many designers, vendors and reviewers. Without firm interface control, RFIs pile up and non-compliances reach site.

• Design review against client standards
• Interface control across disciplines and vendors
• Technical query and RFI management
• Vendor document review
• Compliance tracking

• Contract and technical specifications
• Design programme
• Vendor document schedules
• Client standards

• Design review comment sheets
• Interface register
• RFI and TQ register
• Compliance matrix
• Design status reports

• Common data environment (CDE) used on the project
