About MESCo
Built from experience. Delivered with intent.
McPhee Engineering Systems Co (MESCo) is a Western Australian consultancy specialising in structured systems and compliance frameworks that connect design intent to practical site delivery.

Our Purpose
Simplifying compliance so teams can focus on delivery
MESCo exists to strengthen the connection between project design, execution, and verification — ensuring that what is built on site matches what was intended in the specifications. We transform complex client and regulatory requirements into structured, practical systems that remove uncertainty, reduce rework, and give all stakeholders confidence in the evidence of compliance.
Our Approach
Early involvement, structured systems, ongoing support
MESCo's approach is grounded in structure, consistency and continual improvement. We apply the same principles that underpin ISO-based management systems — Plan, Do, Check, Act — to create order and confidence in project delivery. Our philosophy is built on proactive compliance versus reactive scrambling. Every problem has a solution.

Every framework and workflow we deliver is controlled, traceable and tested in live project conditions by our leadership team. We support civil, mining and infrastructure contractors with systems that make compliance clear, documentation consistent and close-out simple.
