Partner-Led Expertise in Construction Disputes

At gb2, we believe that excellence is only achieved through direct involvement.

We are a lean, flexible, and highly motivated team, focused on helping you achieve the best possible solution through thorough forensic investigation.

Our role is to skilfully guide you through the complexities of dispute avoidance and resolution. Because we have worked for both employers and contractors on some of the world’s largest engineering projects, we offer a rare impartiality. This insight allows us to measure expectations accurately and ensure results are both realistic and fair.

A Team of Accredited Professionals

Our strength lies in our people. Led by a senior team of highly qualified experts, we bring together decades of experience in quantity surveying, engineering, and dispute law. Our team includes:

Forensic Analysis for Every Stage

We provide clarity when it is needed most. Our services are split between keeping projects on track and resolving issues when they arise:

  1. Dispute Avoidance: We provide project reviews, troubleshooting, and strategic advice to prevent disagreements from escalating.
  2. Dispute Resolution: We are regularly appointed as quantum experts, single joint experts, or court-appointed experts in litigation, arbitration, and adjudication.
  3. Investigation & Analysis: This is the backbone of our work, involving cost audits, forensic critical path analysis, and the valuation of claims for loss, expense, or disruption.

"Our aim is to deliver clear, precise, and persuasive opinion based on unrivalled experience and a diligent approach to the facts."

Whether the task is large or small, we have the resources to work with you
