Maintenance Plan Requirements
25.1
General
a)
The PRI-1 Contractor must, as a condition precedent to Construction Completion for each
Portion, develop a comprehensive Maintenance Plan for that Portion.
b)
The Maintenance Plans must describe the resources, methods, systems and procedures to be
used for the maintenance of the Metro Works in that Portion and comply with the requirements
of this Appendix 25.
c)
The Maintenance Plans must identify and address the maintenance of the Metro Works during
both the delivery phase of the IMO Project Works and the long term operation and
maintenance of the CBD Metro.
25.2
Contents of the Maintenance Plan
The Maintenance Plan must include, as a minimum, the following:
a)
a description of all Assets and Asset Components forming the Metro Works;
b)
a comprehensive set of the as constructed documentation identified in Appendix 23 of the
SWTC;
c)
relevant components of Project Plans which relate to maintenance after Construction
Completion including maintenance requirements identified in the Project OHS Development
Plan;
d)
Code of Maintenance Standards developed in accordance with section 25.3 of this Appendix
25;
e)
asset management information that satisfies the requirements of section 25.4 of this Appendix
25;
f)
a description of the maintenance resource and procedural requirements, including:
i.
the numbers, types, skills and qualifications of maintenance personnel;
ii.
roles and responsibilities of maintenance personnel;
iii.

iii.
groundwater ingress rates and groundwater discharge quality targets and limits;
iv.
normal operating condition levels;
v.
unsafe operating condition levels; and
vi.

h)
all details in relation to the durability and Design Life aspects of the Assets and Asset
Components including provisions made by the PRI-1 Contractor in the design and construction
of the Metro Works to satisfy the durability and Design Life requirements of the PRI-1 Contract;
i)
all ongoing requirements to be met during the delivery phase of the IMO Project Works and the
long term operation and maintenance of the CBD Metro to ensure that the durability and
Design Life requirements of the PRI-1 Contract for the Assets and Asset Components are
achieved; and
j)
a procedure for handing over the maintenance of Assets and Asset Components to the
Principal at Construction Completion of each Portion. This procedure must include details on
the training of personnel nominated by the Principal’s Representative.
25.3
Code of Maintenance Standards
25.3.1
Development of the Code of Maintenance Standards
a)
The Code of Maintenance Standards must describe the maintenance standards for all Assets
and Asset Components. The PRI-1 Contractor must develop maintenance standards that
ensure that all the requirements of the PRI – 1 Contract are met at all times during the Design
Life of the Assets and Asset Components.
b)
The PRI-1 Contractor must ensure that the maintenance standards it develops satisfy the
requirements of the PRI-1 Contract and that compliance with them will achieve the
performance, functionality and durability requirements for the Metro Works nominated in the
PRI-1 Contract.
25.3.2
Contents of the Code of Maintenance Standards
The maintenance standard for each Asset and Asset Component must include the following information
as a minimum:

Maintenance Plan Requirements
Information
Description
Reference Number
A unique code reference number.
Asset
Asset description.
Asset Component
Asset Component description.
Maintenance Rationale
The purpose for the maintenance of the Asset or Asset Component.
Defects
The visible or measurable evidence of failure or other undesirable condition
that is to be noted during Asset and Asset Component inspections. The
failure or condition may affect the safety, durability, serviceability, structural
capacity or appearance of the Asset or Asset Component.
Inspection Category
The inspection category in which the Asset or Asset Component is grouped.
Inspection Method /
Frequency
Inspection requirements and explanation of methods not covered by the
generic inspection category.
Item
A category of failure or condition of an Asset or Asset Component.
Measurement Criteria
The criteria for measuring the maintenance intervention level.
Intervention Level
The condition level at which a failure or condition is recorded and prompting
some form of investigation, planning and scheduling of rectification works.
The condition level is described by a severity rating using an objective
recognition procedure. When this level is reached, the failure or condition
must be rectified or emergency measures taken within a specified response
time.
Response Time
The maximum time period from the recognition of a failure or condition to the
completion of the appropriate rectification or instigation of emergency action.
The response time will depend on the:
(i)
severity of the failure or condition compared with the intervention level;
(ii)
potential for personal injury; and
(iii) operational impacts.
Repair Standard
The minimum acceptable condition level following rectification of the
identified failure or condition in relation to the measurement criteria. The
repair standard must ensure that the repair is fully effective, durable, fit for its
intended purpose and consistent with other requirements of the PRI-1
Contract.

to the Principal’s Representative.
b)
The asset management information must include, as a minimum, the following:
i.

iii.
records of the quantity, location, date and type of any maintenance work performed
by the PRI-1 Contractor on the Metro Works prior to Construction Completion; and
iv.
other information reasonably requested by the Principal's Representative.
