English to Portuguese Law/Patents Law (general) Arbitration of a construction project dispute

Quantum expert e, também "quantum expert report" ou somente "quantum".

Exemplos:

"The Respondent also adduced expert evidence on quantum. Mr. XX was called as the company’s **quantum** expert."

"Both **quantum experts** agreed that there are no records available to substantiate the number of man days claimed."

"Moreover, the Parties also provided me with various Scott Schedules, setting out the Parties’ respective positions on liability and the experts’ position on **quantum** in respect of the Disputed Contra-charges."

Perdoem-me os colegas se me enganei, mas ainda não consegui perceber bem se o termo estaria mais bem enquadrado na área da construção ou na do direito. De qualquer dos modos, agradeço, desde já, qualquer ajuda que possam prestar!
