Decoding Complexity. Delivering Certainty.
At Lex Quantum, we provide a fully integrated service, combining both quantum analysis and forensic delay analysis to deliver a cohesive and comprehensive claim assessment. Rather than treating cost and time impacts separately, we align these critical elements to ensure claims are accurately quantified, well-substantiated, and strategically structured. Our expertise is strengthened by the real-time project exposure of our subsidiary company, PQS SA, which has 40+ quantity surveyors actively engaged in live projects. This direct involvement gives us unparalleled insight into the practical implications of claims on-site, allowing us to bridge the gap between contractual theory and real-world execution. With decades of experience in claim evaluation and dispute resolution, we apply technical precision, industry best practices, and data-driven methodologies to support fair and enforceable claim outcomes.
