Dispute Advice

Our construction claims consultants investigate and analyse the cause and effect of the events that have arisen, prepare submissions, and present your case. Their skills and experience are invaluable when analysing contractual liability and causation and quantifying the effects in pursuing or defending claims. This thorough evaluation leads to the best solution for our clients, who may be claimants, defendants, owners, governments, contractors or subcontractors, law firms, architectural practices or engineering consultants.

HJA Dispute Service’s experts can assist with all types of construction disputes:

  • Claims drafting and defence

  • Negotiation strategy and support

  • Claims management and resolution

  • Assessing contract risk

  • Delay analysis

  • Quantum analysis

Our experienced team also has extensive and proven experience of successfully formulating claims under contractor insurance polices to maximise recovery, and also providing impartial expert, independent advice.

Mediation, Arbitration and Adjudication

Our expert dispute resolution team will assess your matter and determine the most appropriate dispute resolution route, whether that be:

Expert Witness Services

Expert witnesses play a critical role in construction dispute resolution. HJA’s dispute services team has provided expert testimony and support in multiple claims and disputes.

Our team has been appointed as independent experts in a range of complex claims and disputes, across major infrastructure and construction projects. We have been engaged by clients, legal advisors, and tribunals to provide expert opinion on matters involving quantum, delay, and technical matters and project management practice.

These appointments reflect our reputation for technical accuracy, commercial understanding, and clear, defensible analysis under scrutiny.

Expert Determination

Expert Determination is a streamlined, cost-effective method for resolving disputes where a neutral third-party expert is appointed to assess the facts and make a binding decision.

At HJA Dispute Services, we provide independent, highly qualified experts with deep industry knowledge to deliver fast, fair, and reliable determinations. This process is particularly well-suited for technical, financial, or contractual matters, offering a confidential alternative to litigation that helps parties move forward with clarity and confidence.

Training

We offer interactive training programs on dispute avoidance, with focus on commercial construction and infrastructure projects.

The HJA Dispute Services team has extensive experience in commercial leadership across a number of commercial models, including traditional and collaborative contracting approaches.

Drawing on this experience, we are uniquely equipped to deliver training on maintaining healthy business relationships in complex major and mega project delivery environments.

Our training programs will support you in managing the relationship with your client or contractor in a way that protects your contractual position, while maintaining transparency, professionalism, and trust. Our approach ensures that commercial integrity is upheld without compromising long-term relationships.
