Design decisions lock in most cost, risk and performance outcomes well before construction begins. TacminMadini provides independent design assurance on behalf of asset owners, ensuring engineering remains practical, compliant and aligned with operational realities. We govern design development across assets and infrastructure by testing assumptions, managing interfaces and controlling scope before issues escalate into cost growth, constructability challenges or operational shortfalls. This assurance-led approach preserves intent, reduces downstream risk and ensures designs are execution-ready without unnecessary complexity.

Why it matters	Designs that are technically correct but operationally misaligned often lead to inefficiency, rework and long-term underperformance. When assumptions are not tested early, problems surface only once delivery or operations are underway.
Our focus	We govern the development of design bases to ensure performance requirements, operating constraints and lifecycle objectives are clearly defined and consistently applied. Assumptions are challenged against real-world conditions, ensuring designs remain fit-for-purpose, constructible and aligned with long-term asset intent.
Outcome	Designs that perform as intended in operation — reducing rework, improving efficiency and protecting whole-of-life value.

Design & execution assurance

Design basis & performance alignment

Multidisciplinary interface governance

Scope control & change assurance

Compliance, safety & constructability assurance

Why it matters	Value is frequently lost at design interfaces. Poor coordination between engineering disciplines introduces clashes, scope gaps and constructability issues that escalate cost and delay once execution begins.
Our focus	We govern interfaces across engineering, infrastructure, services and specialist inputs to ensure information flows are aligned and decisions remain coordinated. Design development is reviewed holistically, not in silos, preserving consistency across disciplines and project phases.
Outcome	Integrated designs with reduced interface risk, improved constructability and smoother transition into procurement and delivery.

Why it matters	Uncontrolled design change is a primary driver of cost escalation and schedule pressure. Without disciplined governance, incremental decisions quietly erode budget, dilute intent and increase execution risk.
Our focus	We provide independent oversight of scope definition and change, ensuring variations are assessed against cost, risk and performance impacts before approval. Design changes are governed through clear decision pathways that preserve intent and accountability.
Outcome	Stable, well-defined designs that support predictable delivery, controlled costs and defensible decision-making.

Why it matters	Designs that fail to consider regulatory compliance, safety or constructability expose owners to approval delays, rework and operational risk.
Our focus	We assure design compliance with applicable standards, safety requirements and regulatory expectations, while testing constructability and sequencing logic. This ensures designs are not only technically sound but practical to build and operate.
Outcome	Execution-ready designs that meet compliance requirements, support safe construction and transition cleanly into delivery.
