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
 Reliability
 Accessibility
 Compatibility
 Innovation
 Sustainability
 Student Experience
 Heritage
 Maintainability and
 Life Cycle
Serviceability
 Precinct Wide Solutions
 Modularity and
Standardisation
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.
