Specialist construction claims and dispute resolution advice
Equitas Consulting is a specialist construction claims and disputes practice advising on delay, quantum, contractual claims and dispute resolution across major international construction and engineering projects. We support contractors, employers, legal teams and project stakeholders where rigorous analysis, clear reasoning and commercially grounded judgement are critical.
Evidence-led analysis.
Commercially grounded advice.
Equitas was established to provide construction disputes advice that is analytically rigorous, commercially grounded and capable of withstanding scrutiny. Our work is built on careful examination of the facts, the contract and the contemporaneous project record.
We advise across the lifecycle of a dispute — from early risk identification, contract administration support and claims preparation through to dispute board proceedings, adjudication, arbitration support and expert appointments. Our role is to help clients understand the strength of their position and present it clearly, accurately and persuasively.
We do not advocate positions for negotiation value alone. We develop opinions and analyses that can be properly supported by the evidence. That approach reflects the principle behind the Equitas name: balanced, independent and defensible judgement.
“Our role is not to amplify a position beyond what the evidence can sustain, but to provide clear, robust and defensible analysis.”
That approach underpins every engagement — whether we are advising on a live project, preparing a contractual claim or supporting formal dispute proceedings.
Led by experience.
Defined by specialist practice.
Equitas is led by a practitioner with a dual technical and legal background, combining construction engineering, project controls, claims strategy and dispute resolution expertise on complex international projects.
Mahkemelerin Gecikme, Disruption ve Quantum Taleplerinde Beklediği İspat Standardı
Metehan Caglar Sonbahar is a dual-qualified construction professional with more than 22 years of international experience across construction, engineering and dispute resolution. His background combines technical delivery, project controls and claims expertise with advanced legal study in construction law and arbitration.
As a Chartered Civil Engineer with postgraduate qualifications in both construction management and construction law, Metehan advises on complex matters involving delay, quantum, contractual entitlement and dispute strategy in both live project and formal dispute environments.
Specialist Expertise
Metehan specialises in the FIDIC suite of contracts and has been appointed as a Dispute Adjudication Board member under FIDIC. He has advised across a broad range of sectors including infrastructure, highways, buildings, manufacturing, power, water, utilities, marine works and industrial facilities.
His dispute-resolution experience spans arbitration proceedings at the ICC, LCIA, DIAC, ISTAC, ITOTAM, DIFC, UNCITRAL and ICSID, as well as alternative dispute resolution through negotiation, dispute boards and adjudication. He has been cross-examined in arbitral proceedings and has given concurrent evidence.
A core feature of his work is the ability to bridge technical and legal issues — from programme and productivity analysis to contractual risk, entitlement review and the structured presentation of complex project events.

He serves as a Committee Member of the European External Aid Committee of EFCA and has published a number of articles on construction and dispute resolution topics, contributing to the development of professional practice in the field.
