Dispute Resolution

Drafting Delay and Quantum Expert reports. Mediate. Testify in court.

Strengthen your case with facts, structure, and credibility. When delays, cost overruns, or unclear contracts put your project at risk, we help you regain control with clarity and confidence. Our independent, evidence-based expert reports are recognised in court and preferred by leading law firms across the Netherlands. Since 1991, Vijverberg has supported Clients, contractors, and lawyers with delay analysis, damage and cost assessments, and clear expert reporting that strengthens every legal position.

Local insight also matters. With a deep understanding of Dutch legal customs and procedures, we build arguments that fit the specific legal context, giving your case stronger footing from the start. And through our strategic alliance with FTI Consulting, a global leader in delay and quantum analysis, we also offer international reach, multilingual expertise, and world-class credibility recognised by the Global Arbitration Review Expert Witness Power Index.

Approach

Information collection and verification – Confirm baselines, record actual completions (As-Built), and gather contracts, minutes, and correspondence.
Identification of delay events – Map and quantify delays at activity level.
Delay and quantum analysis – Apply the most suitable method, such as As-Planned vs. As-Built or Time Impact Assessment.
Reporting – Deliver independent expert reports for negotiation, litigation, or international arbitration.
Testifying – Provide expert testimony where required.

Throughout the process, we hold regular meetings with Clients and their legal teams to review findings, align strategy, and maintain momentum.
