Design Standards Checklist

This document should be read in conjunction with Volume One - Introduction, which provides context on the organisational and governance arrangements that apply to the design and construction of new facilities and describes the key principles that underpin the requirements of the Standards:

Safety

Accessibility

Innovation

Student Experience

Maintainability and Serviceability

Modularity and Standardisation

Reliability

Compatibility

Sustainability

Heritage

Life Cycle

Precinct Wide Solutions

1.2 Purpose

The purpose of this brief is to set out the minimum requirements for the design of electrical services. The aim is to achieve the maximum possible consistency and standardisation across the electrical services systems on the RMIT University campuses. Any design aspects not specifically addressed by this brief shall be identified by the consultant during the design process and shall be brought to RMIT University’s attention for resolution.

1.3 Demonstrating Compliance with the Standards

Designers are required to confirm compliance and justify any proposed deviations by completing the Design Standards Checklist. All deviations must be approved by RMIT prior to commencing design. Unless a robust justification is provided for deviations from the Standards, it is unlikely that approval will be given. Design Standards compliance is achieved through completion of the Design Standards Checklist and endorsement by RMIT of any proposed non- compliances.
