Expert Witness

Qualified quantum expertise for claims, disputes, and litigation and arbitration support.

Expert Witness
and Dispute Resolution Services

Construction disputes typically require a qualified quantity surveyor to provide expert evidence on quantum: the value of amounts claimed or in dispute.

We are experienced across a range of dispute resolution and determination processes, from negotiation and mediation to arbitration and litigation.

We also provide dispute management, commercial and technical support, and independent assessment of quantum for matters which are not subject of legal proceedings.
