Ensure accuracy and value in project costs.
A lean-driven Quantity Surveying practice focused on eliminating non-value-adding activities and maximising value for all project stakeholders. Engagements delivered across New Zealand and Sri Lanka.
QS Cost Auditing & Lean Cost Management Services
Delivering value through lean thinking, cost discipline, and independent oversight.
Managing construction costs is one of the biggest challenges faced by businesses in Sri Lanka. Projects frequently exceed approved budgets, not because of poor intent, but due to non-value-adding activities, process inefficiencies, rework, weak cost controls, and decisions made without timely cost visibility.
My Quantity Surveying practice is grounded in Lean Construction principles, informed by my PhD research in Lean Construction. I apply a lean lens to cost auditing and cost management, not only to check figures, but to identify where value is being lost and why.
As a QS professional, I provide independent cost auditing and second-opinion services that focus on reducing waste, improving flow, and maximising value for money throughout the project lifecycle. Often, a small additional investment in an independent lean-focused review prevents significant financial leakage and saves substantial time, cost, and resources later in the project.
Lean-focused cost auditing approach
Unlike traditional cost reviews that focus only on compliance, my approach integrates lean thinking with QS rigour to:
- Identify non-value-adding activities embedded in project processes.
- Detect cost leakage caused by rework, waiting, over-processing, and poor coordination.
- Critically review variations, claims, and interim payments through a value-based lens.
- Assess whether costs align with client value, not just contractual allowances.
- Provide a clear, independent second opinion to support informed decision making.
How lean QS services add value
- Independent and objective cost audits and second-opinion reviews.
- Early identification of inefficiencies and waste drivers.
- Improved transparency in cost reporting and decision making.
- Better alignment between project costs, value, and outcomes.
- Stronger cost control without compromising quality or intent.
The outcome
By combining Quantity Surveying expertise with Lean Construction principles, clients benefit from:
- Reduced non-value-adding expenditure.
- Improved efficiency and cost predictability.
- More informed financial decisions.
- Projects delivered within approved budgets while maximising value.
In essence, my service is not just about checking costs, but about challenging waste, protecting value, and ensuring that every rupee spent contributes meaningfully to the project's objectives.

Cost auditing · frequently asked questions.
What is construction cost auditing?
Construction cost auditing is the independent verification of construction costs against measured works, the contract, and programme. It confirms whether claims, variations and the final account reflect the value actually delivered, and surfaces errors, overclaims, or unjustified cost impacts before they settle into the record.
When in a project should a cost audit happen?
Cost audits add value at three points: pre-investment cost due diligence, interim valuation and variation review during delivery, and final account auditing at completion. Forensic reviews are typically commissioned when a claim or dispute is already active.
Can you act as an independent expert in disputes?
Yes. The practice provides forensic cost review, quantum analysis and structured expert opinion reports suitable for adjudication, arbitration or litigation, subject to a clear conflict check and written instruction.
Are your services confidential?
All engagements are confidential. A non-disclosure agreement is available on request, and documents are handled with chain-of-custody discipline for dispute-sensitive work.
Which regions do you serve?
New Zealand and Sri Lanka. Remote engagements are the default; on-site attendance is arranged where scope requires it.
