Independent verification

Technical Advisory
& Assurance

An independent technical opinion, written so it can actually be used: what doesn't add up, how much it matters, what to do about it. For anyone who has to sign an acceptance, close a due diligence, or decide whether to trust a dataset.

Independent check on the differences at line crossings, compared against the IHO S-44 uncertainty limits. 2.8% exceed Order 1a, and the out-of-tolerance cloud sits in a single depth band: not scattered noise, but one block with an uncorrected tide. Illustrative dataset.

What it covers

We act as an independent technical party, with a clear mandate and an output that stands up in front of counterparties, insurers and lenders.

  • 01Technical reviewsVerification of specifications, procedures, methodologies, reports and deliverables against contractual requirements and applicable standards.
  • 02Due diligenceTechnical assessment of datasets, assets or projects under acquisition, financing or transfer. What is solid, what is assumed, and where the residual risk sits.
  • 03Contractor oversightTechnical evaluation of bids, capability and system audits, continuous performance monitoring during execution.
  • 04Independent verificationRecalculation, selective reprocessing and cross-checking of critical results, with documented evidence of the method used.
  • 05Technical support in disputesReconstruction of the technical facts, contractual compliance analysis and opinions supporting claim management.

Method

How we write a review

  • 01Explicit mandateWhat is in scope and what isn't, which documents and data were examined, which assumptions were made.
  • 02Graded findingsEvery observation carries a severity, a precise reference to the document, and an impact described in project terms.
  • 03Recommended actionFor every finding, what to do. A review that lists problems without pointing to a way out isn't doing its job.
  • 04Tracked close-outA findings register kept current through to closure, usable as audit evidence.
