About TacminMadini

Owner-side assurance across the capital lifecycle.

TacminMadini provides independent Owner-Side Capital Assurance and Governance Decision Intelligence for complex capital projects and capital-intensive operating environments. We support owners, boards, executives, investors and lenders where capital decisions, reported project performance, developing exposure or deteriorating conditions require independent evidence, challenge and experienced judgement.

Our role is to establish what the available evidence supports, where material exposure is developing and what decisions, conditions or actions require attention. Where engaged, we also develop practical solutions and lead implementation, with scope and responsibilities agreed around the owner’s needs.

Independent assurance tests the position for the owner. Any subsequent implementation has defined responsibilities and deliverables; we do not independently assure our own implementation work.

Delivery organisations execute and report the work. TacminMadini independently tests the position for the owner.


TacminMadini is a lean, senior-led practice operating independently on the owner’s side. We combine project evidence, technical and analytical capability and experienced judgement to clarify confidence, exposure and required decisions.



TacminMadini developed from three decades across engineering, construction, contract mining, operations, transformation and recovery—providing practical insight into how delivery weaknesses affect capital outcomes and owner decisions.



Sarel Blaauw founded Tacmin in 1996 and established TacminMadini Australia in 2018. His four decades across construction, mining, projects, operations, transformation and recovery underpin its assurance perspective.




TacminMadini remains independent of contractor, supplier, intermediary and transactional interests. We accept implementation responsibilities under clearly agreed mandates but do not independently assure our own or related parties’ work.


Begin with the position that matters
