Claims handling analysis and services

Invariably on large projects commercial and contractual claims arise between the parties, either under or in relation to the contract. Under these circumstances, QSi can put in place the necessary claim management systems and apply its expertise to ensure that such claims are professionally analysed, both from an entitlement and quantum perspective, in order to optimise the client’s position.

Typical analyses undertaken by QSi involve delay and disruption, encompassing schedule analysis, productivity studies, acceleration measures analysis, cost analysis and formal audit.

Cost and damages assessment for power projects

QSi has expertise in cost and damages analysis and assessment, combining both audit principles in conjunction with the application of the appropriate entitlement framework (whether arising under contract or at law). QSi will support this work with a detailed report, which can either facilitate settlement or be used in formal dispute resolution proceedings.
