HKA tops list of world’s leading construction expert witnesses for the eighth successive year with 81 experts listed

HKA again emerges as the top firm in the 2024 global Who’s Who Legal (WWL) analysis of expert witnesses in construction. For the eighth successive year, HKA has more expert witnesses commended by the marketplace for their exceptional work across the construction industry than any other consultancy worldwide.

The WWL Construction – Expert Witnesses 2024 analysis involves months of research, canvassing and evaluating the opinions of law firm clients and construction experts from around the world. It is an authoritative international guide to expert advisers and witnesses on quantum, delay and disruption, and damages, as well as forensic technical issues in major construction arbitration and litigation. 

HKA remains the foremost firm in its field, with a world-leading 81 experts, drawn from its offices in America, Europe, the Middle East, Asia, and Oceania. 

Along with topping the construction table for the eighth year running, HKA is also ranked number one in the WWL Performance Index for construction.  

Renny Borhan, HKA’s Partner and Chief Executive Officer, said: “I’m thrilled to see HKA top the 2024 Who’s Who Legal Construction Expert Witnesses analysis again this year. Having 81 experts featured from our offices around the world endorses the outstanding work undertaken by our quantum, delay, technical and damages analysts on some of the world’s largest and most complex construction dispute projects.”

“I would also like to take this opportunity to thank all our peers, clients, and instructing lawyers who took the time to provide references and endorsements for our experts.”

“Enormous congratulations to all of our experts listed in this year’s guide for their commitment and this excellent recognition. This validates their professional standing and reputation in the industry, the outstanding services they provide to clients and the expertise they demonstrate on complex dispute matters,” added Renny.

Experienced as party or tribunal appointed experts, the firm’s experts can advise and, if needed, give evidence under cross-examination – including concurrent ‘hottubbing’ – in jurisdictions worldwide.
