Construction boutique Viltoft is 'quick to react to new cases' and recognised by clients for its 'practical advice', 'quick turnaround' and 'solid market knowledge'.

Fellow practice head Henrik Hauge Andersen is also highly skilled in construction disputes and acted for Copenhagen Zoo against contractor Jorton in a claim relating to the construction of its polar bear facility, 'The Arctic Ring'. Other noteworthy individuals include Steen Hellmann, who was instructed by 3B in several disputes with contractors and suppliers, who claimed damages for the use of magnesium oxide boards on the client's housing projects; Peter Fauerholdt Thommesen, who assisted Hovedstadens Letbane with the construction of The Greater Copenhagen Light Rail including 27 stations outside of the capital; Morten Ruben Brage, who is particularly strong in environmental and planning issues, and Eva Olesen, who regularly acts in construction-related arbitrations.
