The Global Standard for Infrastructure Asset Management

Our Role:
Principal Authors of the IIMM

Sandy Muir, Director of Odysseus-imc Pty Ltd, is one of the principal authors of the early International Infrastructure Management Manual. This places Odysseus-imc among a select group of practitioners worldwide who have shaped the development of strategic asset management as a discipline.

As co-authors of successive IIMM editions, our team has:

• Developed foundational methodologies that define modern infrastructure asset management

• Contributed case studies drawn from real-world infrastructure projects across water, transport, health, and local government sectors

• Established industry best practices now adopted by organisations globally

• Aligned IIMM guidance with evolving ISO 55000 standards through direct involvement in standards review committees
  
  

With over 43 years of infrastructure experience, we don't just teach asset management principles—we created many of them.

Why IIMM Authorship Matters for Your Organisation

When you engage Odysseus-imc, you're working with the practitioners who literally wrote the book on infrastructure asset management. This expertise translates to tangible benefits:

Proven Methodologies

We apply field-tested frameworks developed through decades of real-world infrastructure projects, not theoretical approaches adapted from other industries.

Best Practice Insight

Our involvement in IIMM development means we understand what works across diverse sectors—from water utilities and councils to healthcare facilities and transport networks.

Standards Alignment

Direct participation in ISO 55000 review ensures our guidance reflects both international standards and practical Australian implementation requirements.

Continuous Innovation

As the infrastructure sector evolves, so does the IIMM. Our ongoing involvement means clients benefit from the latest thinking in climate resilience, digital transformation, and sustainable infrastructure management.

The IIMM and ISO 55000:
A Complementary Approach

The 5th Edition of the IIMM, released in 2015, was specifically developed to align with the introduction of ISO 55000 Asset Management Standards. As members of the ISO 55000 review committee, Odysseus-imc helped ensure this alignment delivers maximum value to practitioners.

ISO 55000 provides the "what"—defining requirements for an asset management system IIMM delivers the "how"—practical guidance, tools, templates, and case studies for implementation

This complementary relationship means organisations can achieve ISO 55001 certification more effectively by following IIMM methodologies. Over 120 case studies in the IIMM demonstrate good practice across diverse infrastructure types and geographies.
