About

Dr Nilmini Thilakarathna.

Twenty years of chartered Quantity Surveying, and more than a decade lecturing. The work splits between construction firms in New Zealand and Sri Lanka that need independent cost assurance, postgraduate researchers who want structured mentoring, and QS students across Sri Lanka, the UAE, and overseas.

The Founder

Both sides of the desk.

Twenty-plus years in pre- and post-contract roles, ten of them as Group Chief Quantity Surveyor, running feasibility, cost control and regulatory documentation across 15 to 20 concurrent projects.

Senior Lecturer at Ara Institute of Canterbury, leading the B Cons (CM/QS) programme. Before Ara: Otago Polytechnic and the University of Moratuwa. PhD research covered human capital in lean construction, knowledge management, and competitive bidding.

The practice is named for retrieval: the work of lifting someone from where they are to where they need to be. Same instinct whether the target is a defensible final account or a confident dissertation defence.

About the Practice

Academic excellence, meeting real-world practice.

The practice does two things most firms keep separate: independent cost auditing on live projects, and academic mentoring. The standards overlap more than they look.

Independent of any contracting party. No ghostwriting. Work that has to stand up under audit or peer review, either way.

Value 01

Responsiveness

Timely answers, clear scope, and continuous communication. Critical matters triaged within 48 hours.

Value 02

Integrity

Independent and ethical. No conflicts, no hidden incentives. Only chartered standards.

Value 03

Precision

Every certificate, variation and report is traceable to measured quantities and documented reasoning.

Next step

Every enquiry begins with a conversation.
