Dispute Resolution

Strengthen your case with facts, structure, and credibility.

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

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. Because local insight also matters, Vijverberg brings a deep understanding of Dutch legal customs and procedures. This enables us to build arguments that fit the specific legal context, giving your case stronger footing from the start.

For international arbitration in construction disputes, Vijverberg has formed a strategic alliance with FTI Consulting. FTI Consulting ranks among the global leaders in construction delay analysis and quantum analysis, and is annually listed in the top three of the Global Arbitration Review’s Expert Witness Power Index. Together with FTI Consulting, we provide multilingual experts with in-depth and diverse expertise in delay and quantum analysis for projects worldwide.

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.

What to expect?

Build credibility with independent, court-recognised analysis

Strengthen your legal position with objective, fact-based assessments. We review contracts, schedules, correspondence, and project records to uncover the factual basis of a dispute. Our independent reports increase your credibility and improve the likelihood of a successful outcome, whether in negotiation, litigation, or arbitration.

Gain depth and speed with a multidisciplinary team

Move forward confidently with faster, sharper analysis. Each case is handled by a team of specialists in planning, contracts, and project execution. Their combined expertise allows us to deliver robust, defensible analyses quickly, saving you time while improving the quality of your evidence.

Rely on proven, internationally recognised methods

Trust conclusions backed by global best practices. We apply standards such as the Society of Construction Law’s Delay and Disruption Protocol and AACE International’s Recommended Practice for Forensic Schedule Analysis. These recognised methodologies ensure your case is supported by clear, defensible reasoning.

Work with qualified experts you can rely on

Gain the confidence that comes from recognised authority. Our lead experts are Registered Dutch Court Experts (LRGD), trained at the University of Leiden, and experienced in both Dutch and international proceedings. Their expertise ensures your evidence stands up to the highest level of scrutiny, even in high-stakes environments.

Leave no evidence overlooked with advanced data analysis

See the full picture and strengthen your argument. We combine decades of construction experience with advanced data analysis to review large volumes of project information efficiently and precisely. With AI-supported datamining, we examine everything from full project archives to staff mailboxes, ensuring every relevant fact is identified, verified, and used to reinforce your case.
