We have a long-standing presence in the Asia Pacific region and opened our Singapore office in 2020, enabling us to offer our expertise locally, supported by our large team of global experts.

Despite challenging times during this pandemic, our team have enjoyed collaborating with the vibrant local arbitration community, hosting workshops with local law firms and speaking at arbitration conferences in Singapore and Hong Kong.

This year, we also welcomed Christopher Nunns as our third Asia Pacific-based partner. Chris is a highly respected quantum expert with 40 years’ experience in the construction industry, including 30 years based in Singapore, primarily involved in dispute resolution, arbitration, contract administration and claims management. He has given expert evidence for arbitration and court proceedings and is a past Chairman of the Society of Construction Law in Singapore.

Chris joins our other Asia Pacific partners: Sharon McGahey, an experienced delay expert with more than 19 years in the construction industry, and Chris Johnston, a quantum expert who has been appointed on several matters, including SIAC arbitrations. The team are currently working on a number of projects in the region, with the support of more than 200 professionals across our four global brands:

Blackrock Expert Services provides delay and quantum expertise globally, including on some of the world’s most high-profile construction and engineering projects.

IT Group carries out expert analysis of all aspects of technology, data security and telecommunications disputes.

Haberman Ilett is a specialist forensic accounting firm dedicated to providing accounting, financial and valuation services in the context of disputes across a wide range of industries and geographical areas.

Martello Financial Services provides experts to support commercial disputes and regulatory investigations across the remit of financial services.

Across the group, we have extensive experience in Asia Pacific in transport, media and communications, construction and engineering, oil and gas, financial services and health care.  

From India to Brunei to Australia, our office in Singapore will help us continue to strengthen our service offering in the region.
